How to Cast Platinum (Platinum Casting Process) and Platinum Casting Equipment Buying Guide

Platinum boasts an exciting history. In Egypt, between 1200-700BC small quantities of Platinum were used alongside Gold to create decorative objects. La Tolita Indians bordered a rich source of platinum; between Colombia and Ecuador. They used platinum to make earrings, nose rings, and masks. Though these kinds of uses were isolated, they have been carefully documented by scholars and researchers. Platinum has been used for luxury reasons for thousands of years.
 
Platinum bears unique characteristics that make it an ideal metal for fashioning jewelry. This also explains why it has evolved slowly but steadily over time. This luxurious metal has a melting point of 3221.6 degrees. It is very strong and highly durable, which means you can’t change its shape and form before softening it.

Until the 19th century, no one had a clue of how to make platinum malleable. Early Egyptians and Indians used techniques that were lost somewhere in history. The same happened to its sources. The modern discovery of platinum dates back to late 1600s. During this time, it was used, but people believed it to be an unusable immature type of Gold. At this time, platinum remained obscure since its value was still not known.

Chapter 1:

Introduction of Platinum

Platinum has been used for at least three centuries now. This means that the mining started in the 1600s. It is imperative to note that the ancient methods of platinum mining were quite primitive. In this section, we intend to look at both ancient and modern platinum mining methods to help you understand how technological advancement took effect in this regard. 

1.1, What are the Characteristics of Platinum?

In the 16th century, platinum was thought to be platina or rather little silver. In the 18th century, it was termed as the only best metal for a king. Let us take at some striking characteristics of platinum. 

The element has a chemical symbol Pt and is a silvery-gray metal. It is one of the only six metals that feature platinum group metals. There are other platinum group metals (PGMs) such as osmium (Os), iridium (Ir), ruthenium (Ru), rhodium (Rh), and palladium (Pd). Albeit platinum is rare, it is the most common of all the PGMs.

In the jewelry industry, platinum is used alloyed with other PGMs. Compared to pure platinum, platinum alloys weigh less, but they are harder than the pure one.

When a measurement is taken in parts per billion of the earth’s crust, platinum is more common than gold. However, it tends to be more dispersed and harder to refine. This makes it have a higher price. Platinum also occurs in meteors and asteroids alongside other metals such as titanium, cobalt, and nickel.

Due to the terrestrial quantities of platinum group metals, researchers are now strongly considering asteroid mining. Platinum is one of the heaviest metals on earth. 15 cm of the metal weighs around 75 kg (165 pounds); the same weight as an average adult male. Platinum is also easily malleable and ductile, although less compared to gold. Out of the three most common metals, platinum has the least metal memory. This makes it one of the best substances for making jewelry.

Once platinum is bent, it retains that shape until it is bent into another shape and form again. Since it is quite dense, which makes it add strength to delicate designs of jewelry? Platinum is also highly durable.

When the substance is scratched, it just gets displaced instead of breaking or getting chipped. This makes it easier to repolish without losing its original weight. It has a high resistance to corrosion, and will never react with water, air, heat, or any other chemicals.

1.2, What are the Platinum Application

Platinum is an essential industrial metal. It is used in a wide range of industries where it plays a central role. It is mostly used as a military resource due to its unique properties. The overall demand for platinum falls under at least eight broad categories.

  • Jewelry – best substitute for silver and gold
  • Automotive- in catalytic converters, sensors, and spark plugs
  • Chemical processing- used as a general catalyst
  • Petroleum refining- used as a catalyst in cracking crude oil
  • Medical/dental – reconstructive and equipment
  • Glass- dies and process technology
  • Investment – coins and bullions

Platinum has gained popularity in a wide range of industries due to its authentic properties. Some industries use it because of its unique appearance, durability, malleability, ductility, and due to the fact that it is less reactive.

1.3, The History of Platinum Jewelry

Platinum boasts an exciting history. In Egypt, between 1200-700BC small quantities of Platinum were used alongside Gold to create decorative objects. La Tolita Indians bordered a rich source of platinum; between Colombia and Ecuador. They used platinum to make earrings, nose rings, and masks.

Though these kinds of uses were isolated, they have been carefully documented by scholars and researchers. Platinum has been used for luxury reasons for thousands of years.

Platinum bears unique characteristics that make it an ideal metal for fashioning jewelry. This also explains why it has evolved slowly but steadily over time. This luxurious metal has a melting point of 3221.6 degrees. It is very strong and highly durable, which means you can’t change its shape and form before softening it.
 
Until the 19th century, no one had a clue of how to make platinum malleable. Early Egyptians and Indians used techniques that were lost somewhere in history. The same happened to its sources. The modern discovery of platinum dates back to late 1600s. During this time, it was used, but people believed it to be an unusable immature type of Gold. At this time, platinum remained obscure since its value was still not known.

Platinum found its way to the European scientific community in 1741. It happened that William Browningg, an English man who was a physician and a scientist starting experimenting with samples he received from his brother-in-law. A native Colombian Platinum was used in the experiment. Throughout the 1700s, chemists worked tirelessly, trying to find the best ways to melt and refine platinum.
 
In 1800 it was found that arsenic and platinum powders fused when mixed. Things become better when it was later discovered that platinum could be melt with the help of flame that has hydrogen and oxygen. Later on, a blowpipe was invented using the gases to help melt the substance. Since the methods were dangerous, the mainstream workshops were loath to adopt them.

For more than three thousand years, platinum has been used to make important items. In ancient times, the jewelries were used to symbolize power, wealth, and luxury. Today, the jewelries made with platinum are mostly used to show a luxurious lifestyle. But this is not 100% the case as there are many other things that could be made out of platinum. The ancient Egyptians and Indians used the substance to make masks, earrings, and nose rings. We intend to delve deeper into this as we discover more about the substance. 

Chapter 2:

What Casting Method Should I use?

Many casting methods can be applied to platinum. However, you need to choose wisely, depending on your budget and the amount of platinum you have. In this section, we have mentioned some of the best casting methods you can choose to apply.

2.1, Vacuum Pressurized Casting

Superbmelt Machines are the most suitable for melting and casting metals of very high melting temperatures, such as platinum. As per their model and design, they have the capacity to melt steel. They can also work on metals or alloys of very low melting points such as aluminum. This means that they come in handy for melting and casting a wide range of substances. 

2.2, Centrifugal Casting

If you need to use centrifugal method to cast platinum, then it ought to leverage a temperature of at least 1800 degrees. This is the required maximum temperature to melt and cast platinum. It might feature a gas argon atmosphere and a vacuum pump, but there are optional. However, they come in handy when you need to protect the substance from oxidation. If possible, it should come with an IR temperature reader to help you determine whether the right temperature has been arrived at.

2.3, Other traditional casting methods

If you have a company that casts platinum, you might want to apply the best method that would give you the most impressive results. We have seen that you can either use Vacuum Pressurized Casting or centrifugal casting. However, according to our fifteen-year experience in casting elements, we have used both methods, and we are here to share the reason we feel that Vacuum.

2.4, Pressurized Casting should be your number one choice

First of all, you are supposed to consider the speed at which the two methods work. Without being bias in any way, Vacuum Pressurized Casting beats centrifugal casting with a landslide. It is also economically feasible being that it works pretty fast, and there is not a lot of learning curve involved. Note that with Vacuum Pressurized Casting, you will not be using some traditional method that would reduce the quality that you get from your work as a mineral-oriented company.

2.5, Other traditional casting methods

Pressurized casting is a process that features that se of a compressor and a pressure chamber to get rid of bubbles from the casting out from a casting resin or the mold rubber. The pressure casting technique is mostly used by expert prototype model makers who don’t want to see even a single bubble, but that is how it ought to be. A single bubble located on the surfaces of the casting might cause the entire casting to be discarded. 

I. How Does Pressure Casting Work?

  1. A liquid plastic is mixed and then poured into the rubber mold
  2. The whole mold structure is put into a pressure chamber
  3. The lid or door to the pressure chamber gets closed and then secured tightly to prevent air from moving in.
  4. The pressure will then be turned on, and the resin and mold are subjected to up to 60 psi pressure until the resin gels up..
  5. The bubbles are then collapsed into the solution, and you will get a bubble-free casting

 

II. Can I make the Mold under Pressure?

If you intend to use a rubber mold regularly in the casting process, it would be best if you made the rubber mold under high pressure as well. This implies that you will mix and pour the mol rubber over the initial model, putting the structure inside your pressure chamber and then applying a pressure of up to 60 psi until the mold cures.

 

III. The Reason for Doing This

If you are pressure casting resin in the rubber mold that has not been subjected under pressure, in case of any bubbles in the rubber mold, they might implode under pressure, and then the collapsed bubbles might get reflected in the finished casting. They will show as dimples or bubble positives.

IV. What to Note

Once you have started making a mold of a hollow model and you intend to do it under pressure, it might end up collapsing under pressure.

It is advisable to only use commercial pressure chambers. Many resin casters have learned the hard way that most home-made pressure chambers might end up exploding violently hence causing serious injuries.

It is important to ensure that the running air from the compressor is kept dry. This is mainly used for pressurizing the pressure chamber. The moisture available in the airline will react deeply with urethane resins and rubbers. When this happens, it will cause foaming or bubbles. The airline driers can be found from industrial supply stores and dealers.

 

V. Importance of Pressurized Casting

Pressure die casting is fast and highly convenient compared to other methods. This makes it reliable and very cost-effective. It is mostly used by those looking to producing high volumes of professionally casted metal components that are net-shaped with tight tolerances.

The pressure die casting technique encompasses injecting under high pressure a perfectly molten alloy into a steel mold. This will then get solidified fast to form a net-shaped component. The casters will automatically extract it.

Let us take a look at some of the basic importance of pressurized die casting

  1. Highly cost-effective compared to other methods
  2. Castings done within thin walls, which makes them lightweight
  3. Castings are done with close dimensions control and excellent surface finish

Before we continue, it is worth mentioning that there is high-pressure casting and low-pressure casting. Therefore, you need to understand the exact type of machine you need to use for the casting process. High-pressure casting will always feature a wide application of at least 50% of all casting production. In the current market, low-pressure casting only accounts for 20% of the entire production, but its use has also increased over the years.

 

VI. More about High-Pressure Casting

In this case, the liquid metal gets injected with high pressure and speed into the metal mold. The basic equipment features two vertical platens. The bolsters are then placed on the two platens and to hold the die halves. One of the two platens is movable while the other one of fixed. This kind of model will help the system to open and close. A given amount of metal is then poured into the shot sleeve. Later on, it will be introduced into the mold cavity. This must be done with the help of a hydraulically driven piston. Once the metal has solidified, the die gets opened, and the casting is removed.

 

VII. What about Low-Pressure Casting?

This is the method that is used when you want to manufacture high-quality aluminum alloys together with magnesium and other alloys with very low melting points. Most of the time, aluminum with the weight range of 2-150 kg is cast using a low-pressure casting method.

This is how the process works. The metal die is placed above a furnace that is sealed and contains a molten metal. A refractory-lined riser then extends from beneath the die all the way into the molten metal. Low-pressure air of between 15-100 kpa, 2-15 psi is deployed into the furnace. This will then make the molten metal to rise up the tube and before entering into the die cavity with very low turbulence.

Once the metal has solidified, the air pressure gets released. This will make the metal that is still in a molten state in the tube riser to collapse back right into the furnace. Once the subsequent cooling has occurred, the die gets opened, and the casting is extracted.

 

VIII. Platinum Devesting

You will learn that there are quite some challenges in removing the investment. The investment is usually baked at very high temperatures, which make it turn into a glass-like substance that can be hard to remove from the cast pieces.

To most manufacturers, hydrofluoric acid works best, but this might be extremely dangerous, especially when you are a novice. If you have to use this method, then you must be very cautious. Make sure to use some rubber gloves, a respirator, and a rubber apron. The respirator helps to filter tiny particles from the air.

If you run a smaller shop, then you might need to use a devesting agent that is created specifically for platinum investment. It is used as the best substitute for hydrofluoric acid. Since there are several brand names, you want to ask your supplier about the right one to use. We can give you detailed information on the same to ensure that you are safe.

 

Chapter 3:

Understanding the Process of Platinum Casting

To cast platinum, it is essential to understand how the entire process works. You should also be able to repeat the same functions on a consistent basis. Due to enhanced technology, small scale platinum casting has become easier than ever.

Ricardo Basta, in 1986, chose to start platinum casting. He spent a lot of effort trying to learn everything possible regarding the process. Unfortunately, he never achieved substantial success. He wanted to understand the properties of platinum as well.

No one had an idea of how to cast platinum when Eichberg started. He worked alongside a few employees. Interestingly, they were not even aware of the essence of insulating gloves and their ability to protect them from burning. Most of the time, they had wet rugs around their arms and cheeks to keep them safe. They were not adequately equipped.

Eichberg never gave up anyway. Through trial and error, he started the learning process. If you looked at his first casting, you would be convinced that he lacked experience. He had quite a number of drawbacks, such as cracks in the metal, no so good surfaces, and porosity. In case there was a problem, he tested many things until he got a better casting.

The popularity of platinum is just fairly good, which means that the learning curve with the metal has decreased exponentially over time. In the few previous years, the level of demand for platinum has increased significantly. Due to the increased demand, more manufacturers contemplate joining the industry of smelting and casting platinum. If you have been thinking of joining this industry, then you are on the right track. If anything, platinum casting is not as hard as it used to be back then.

It is imperative to note that platinum casting is a little different compared to silver and gold casting. Unless you are prepared for the process, and that you understand it well, you will just go through lots of frustrations. To achieve a good level of success, you ought to have the proper equipment and elaborate process control. We are about to let you know everything regarding casting platinum to get you started.

How Does Superbmelt’s Vacuum Casting Process Solve the Problems Caused by the Casting Process?

The platinum casting process is not simply a walk in the park. Even by following the right procedures, there are certain problems that you have to deal with. Thankfully, our team at Superbmelt has the most applicable solution for you. Read on to discover some of the issues our company is there to help you with.

1, Air Entrainment in Wax

Bubbles that are found under the surface of the wax can either appear when air found in the mold is trapped amid the wax injection process, or when it is introduced into the mold alongside the wax. Regardless of the case, the air bubbles might pop if it happens that the casting equipment gets vacuumed. The void gets filled when the bubbles pop, and the investment gets slurry. Later on, the metal gets filled around the investment formations. Most of the time, they appear as tiny round holes in the castings.

SuperbMelt will always inspect investments for the availability of bubbles. This is done by holding them up to a source of light, and then looking through them.
If you see some light spots, it means that there are bubbles in the wax, and they need to be removed. It is the readability of your wax that determines how easy it will be to see the bubbles. You will then remove the bubbles using a heated wax tool to pop them. You will see exposed holes that you need to fix with wax. These things can be done by SuperbMelt, and we will ensure that you get nothing but quality work.

Wax in molds tends to have different viscosity. However, this will not deter you from seeing the imperfections that you need to fix. There is only one perfect way to deal with the bubbles, which is by eliminating the source of the bubbles. The nature of the air you intend to remove dictates the method used to remove them. The air might get trapped amid the injection process, or it might have been introduced alongside the new wax.

It is advisable that air should leave the mold at a faster or rather equal rate compared to the wax that is being injected. It gets trapped if this does not happen. These trapped can be removed or prevented by applying powder properly in mold vents. This will then clear air from the mold cavity amid injection. You can also reduce trapped air in molds through the reduction of pressure and then slowing down the injection rate.

There are some instances in which air might get rapped in molds, especially if the air has to flow backward in the form of turbulent to fill the pattern. This is always the case due to the manner in which the model is gated. Some problems in casting might be caused due to the method of gating configuration.

Air can also be introduced in the mold alongside the wax that comes from several sources. Dissolved gas is one of the many sources of air that can be introduced into the mold. Another instance is when air gets trapped when fresh wax dots or chips are introduced into the wax pot. What happens that the tiny air spaces in between the cold wax chips get covered by molten surfaces before they can escape. These bubbles could get trapped until they get injected into the molds.

To overcome these challenges, you need to pre-melt the wax in the reservoir unit and then vacuum de-gas it having it loaded into the production wax pots. Superbmelt will use a transparent lid that has an airtight lid, with a fitting for the vacuum line alongside a separate vacuum release valve. In case these resources are not available, you can choose to vacuum de-gas the production pots. While doing this, make certain that the pressure gauge is well isolated on the wax pot amid the vacuum de-gas process. To do this, have a small ball valve installed between the wax pot and the gauge. Then make sure to close the valve when you are about to start the vacuum pump. You must never de-gas a full wax pot since some wax might end up in the vacuum hose. Water vapor is another source of air that gets trapped in the mold. This comes from condensation that happens in the compressed airlines.

2, Wrinkled Surface

Wrinkled surfaces can be caused by a number of factors. For instance, if there is an inadequate escape route amid wax injection, the wax pattern might not fit completely. This defect usually leads to another, which means avoiding them is necessary. If the pattern doesn’t fill, this then makes the worker increase the injection pressure. Once the injection pressure has gotten so high, the worker is compelled to apply a higher clamping pressure on the mold. This is done to prevent the wax from leaking out through the sides. Many other problems can also be encountered. 

Due to the mistakes in the combination of the three pressures-injections, forward and clamp-pressure usually features seams and non-fills. It might as well lead to the wax-bubble problem. In case of too much forward pressure, the mold might split to let more air into the wax stream. The mold has a tendency to split, which makes an additional pressure of clamping necessary. This helps to keep the wax from leaking. Due to extra clamp pressure, small vents could be closed to trap some air on the inside.

This problem normally comes about due to hand wax injection due to the variable nature involved. It is crucial to avoid this problem at all costs, and this is where SuperbMelt comes in. With the auto-clamp system, you can discover, document, and repeat the proper pressure combinations, thereby letting you get rid of the three pressures from the affected areas.

3, Tree Building Defects

Wax tree is another main source of defects. The quality of the connection between sprue and the gate is the main issue we are talking about here. The get is the section that connects the jewelry wax piece and the central trunk of the wax tree. Central talk can also be referred to as the sprue.

The sprue/gate connection must be smooth and sealed all the way around. It is not advisable to use a wax pen to create a hole into the sprue and then having the gate inserted into the wax spot, but this is the mistake made by most individuals. If this method is used, it leaves many sharp inward points or angles in the wax. This will finally turn into sharp pieces of investment, and they can break off during the casting process. When this happens, they get pushed toward the exteriors of the mold cavity due to the disparity in the overall density between the investment and the metal.

It is possible to use a wax to create a filet at the base of the sprue/gate junction. This will help you avoid the possible situation that might ruin everything you have been working on. There is a better solution, which involves using a tiny smelting reservoir and sticky wax to get the job done a little faster and minimize the chances of defects. Even with this, sealing the base of the sprue/gate is necessary. This way, you will be able to come up with a smooth filet.

Even with the sticky wax, you still need some ea pen to get the parts sealed. Once you have dipped the end of the wax gate inside the sticky wax, the moving time between sprue and wax reservoir will allow the sticky surface to cool down slightly. Once this has happened, the unsealed gate might come off the sprue wax. This problem can be avoided by picking up the wax pen once per column or row and then sealing them.

4, Dewax Defects

At Superbmetl, we have what it takes to see that you are getting the best services at all times. Dewax defects is one of the main problems associated with platinum casting problems. But we are here to ensure that this does not bother you. Below is how you can dewax without the worry of observing any defects once you are done with the process. 

Now that you have the mold and are ready to remove the wax, let’s show you how you can do it. Make sure that the molds are put into an autoclave while the wax is exposed, with the end facing downwards. During this time, the autoclave must remain closed. The steam should be injected into the autoclave within the shortest time possible. The steam will then pressurize the vessel to expose the mold to very high temperatures that go beyond 300F. The steam is the one that heats the wax. The steam pressure is necessary to offset the pressure due to the heating. This process will then expand the wax on the inside of the molds.

The wax will keep heating, and while it does so, it melts very fast and drains rapidly from the open end of the mold. This method is reliable since you will have 100% of the wax captures and then recycled so that you can use them again later on. The molds will be removed from the autoclave within a very short time. You will then let them cool down and dry.

This is mainly done in investment casting. Other casting methods also have their unique ways of getting things done. You will learn that they require the molds to be opened before the pattern can be removed. However, in investment casting, you can simply have the pattern melted, thereby allowing for improved detail in a perfect mold.

5, Cold Shuts

Cold shuts are surface imperfections that might occur in a material regardless of the casting or molding process used. We are talking about defects that can be seen by an unaided eye. These imperfections usually lead to rejection of the castings, which means that they need to be avoided at all costs. They might as well be referred to as the cold lap points. At Superbmelt, we have everything in place to ensure that these mistakes do not occur.

Cold shuts might take place when two metal streams fail to fuse together perfectly. This usually leads to some discontinuity or rather weak spots on the inside of the casting. Most of them tend to look more like cracks. Low pouring temperatures, too cold shell or slow pouring speeds are some of the major potential causes of cold shuts.

Platinum Casting Equipment Buying Guide

Whether you are an established company or a start up, knowing what to consider when buying platinum equipment is important. We do care for you, your money, and the productivity of the company. Therefore, we believe that with this buying guide, you will not make a wrong investment. Take a look at some of the things you should be looking for before making a purchase.

  1. Consider the Price

Nothing is more important than thinking about the price of the product. Though you are looking to optimize the productivity of your company, make sure that you do not put all your money into this single bit of the project. Do your homework and come up with a budget. This budget will help you determine the maximum amount of money you can spend on platinum casting equipment. Note that it is possible to determine the budget by coming up with an integral plan. If you are looking to do lots of production, then you will need an advanced machine, which might cost a little higher.

  1. Consider the size of the production

Your choice of platinum casting machine should be inspired by the scale of production for which you intend to apply it. There are platinum casting machines of all sorts. If you are looking to do a lot of production, then you need to get a machine that can easily stand that sort of work. However, there are ones meant for small shops, and they are great for small scale production. Before you start shopping, understand the nature of your company along that line, and you will never go wrong. Superbmelt should be your number one stop if you are looking for machines that match the type of work you intend to do.

 

  1. Consider the features

Always invest in machines that feature unique features to enhance the productivity of your company. Understandably, the features play a central role in determining the prices of various casting machines available. However, if you go for the best, then you will always have a long-term financial gain because you shall have gained a competitive edge. Some machines are automatic, while some come with parts that are mostly manual. Note that because a machine is manual does not mean it won’t function optimally. Just take your time and think carefully so that you make the best decision.
