1. What is lost wax investment casting?

Before casting any jewelry or dental, you must have a wax model, which can be obtained through a 3D printer or traditional wax model making methods. In either case, the wax model determines the casting result. Next, we put the wax molds together to make a small wax tree. Of course, we cannot allow any wax mold to touch, make full use of the casting space and make high-efficiency production.

We put the wax tree in a container and then we can start producing plaster. At this time, we use a vacuum shaker. Under vacuum conditions, the formation of bubbles in the plaster affecting the casting is avoided, and the plaster is filled into the mold. Put the formed plaster mold in a high temperature baking wax oven, so that the wax melts and discharges. The next most important step is to use our mini casting vacuum casting machine, which is a combination of melting and casting, and everything is done under vacuum.

After installing the machine, put the gold into the dry pan, put the plaster mold in the same position, close the lid and start to melt. After the casting is completed, remove the plaster mold, clean the finished product in a sandblasting room, and go through a series of processes such as polishing and polishing. The exquisite jewelry is presented to you.

The SuperbMelt Mini Vacuum Pressurized Jewelry Casting Kit is designed to cast the largest. 300 grams of precious metals and dental metals; the highest temperature can reach 2600℃, suitable for the casting of gold, platinum, palladium and silver; this machine is specially designed for small batch jewelry casting, jewelry sample making, dental casting and some DIY precious metal casting; plus Pressure and vacuum casting ensure that castings are free of porosity and shrinkage; inert gas protection to prevent oxidation of precious metals; PLC control and automatic casting machine functions make manual casting operations more convenient and reduce failures. Any precision jewelry and metal artwork can be perfectly produced using Superbmelt vacuum pressure casting machine. We also provide a complete one-year warranty and on-site training services worldwide.

2. What are the different types of casting process?

Casting is a process that can be done in a wide range of ways. The method you choose to use determines what you end up with.

First, we have the sand casting which is the process one can used to produce sand molds. Sand casting might be a great choice for those looking to produce iron, sheet, and many other nonferrous alloy castings.

Next, we have what is known as the investment casting. With this method, you will need to make some patterns in a fusible material. You will cover the surface of the pattern with many layers of refractory materials.

We also have die casting. This one involves the use of high-pressure metal liquid by pressing it into a precision metal cavity at a very high speed. The metal liquid will then be cooled and solidified under extremely high pressure to form the casting.

There are many other types of casting like low-pressure casting, centrifugal casting, gravity die casting, and on the list goes.

3. What happens in the vacuum chamber?

The vacuum chamber might seem like a complicated place, but that is not what it really is. In this chamber the machine will suck out all the metal into the mold. Note that there is a need for enough force to resist the surface tension of your molten metal.

Unless that is done, your molten metal will just stay there because it will turn into a blob. In the vacuum chamber, there is adequate steady pressure to help you achieve the bottom line without breaking a sweat.

The molten metal is also placed in the vacuum chamber to make sure that there is no air bubbles on the inside. If the air bubbles are not gotten rid of, you will not end up with a product of the best quality.

4. What are the advantages of investment casting?

Platinum’s high melting point (around 1768°C) and reactivity with certain crucible materials are the main challenges in casting it. To avoid issues, always use a quartz or high-purity ceramic crucible rated for platinum’s melting range, and ensure the vacuum chamber reaches proper pressure before melting begins — this prevents oxidation and porosity in the finished piece. SuperbMelt’s investment casting kit automates temperature and vacuum control throughout the process, reducing the risk of operator error.

5. What tools or materials do we need for jewelry casting process?

There are so many things you might want to make as a jeweler. If you would like to invest in this lucrative business, you might want to invest in these tools and materials;

Flat nose pliers
Round nose pliers
Nylon tipped pliers
Wire cutters
Titanium alloy,
Gray iron,
Aluminum alloy,
Steel,
Copper and Zinc

There are other materials like practice material, ruler, disk punch, jeweler’s saw, and many more. Do not forget to invest in wire. Wires are highly versatile, so you need to know what exactly you need to invest in. We have aluminum, rose gold, gold-filled.

Best of all, once you have decided to become one of the best jewelers in the industry, it is vital to make good use of your imagination. If you can make outstanding items at all times, breaking through the market will become one of the easiest things.

Aside from investment casting kit, it is important to always have a lubricant when using a jeweler’s saw. That is the only sure way to keep your fingers safe when doing your thing. Also, the lubricant will ensure that the blades don’t break and that the cutting edge is also preserved.

But again, you don’t have to finish the product on your own due to the level of quality demanded by modern clients, and the fact that there are so many risks involved.

If you try to complete the process on your own, you might start the work, only to learn that you do not have everything that is needed. But since we are specialists, you will never feel disappointed if you let us do the work for you with our investment casting kit and other materials.

The safety standards and regulations are also up to par. As such, you don’t have to risk hurting yourself when our duty is to help you as you focus on other essential aspects of your business.

6. What is a jewelry wax made of?

You will need resin to make your jewelry wax with the help of investment casting kit. This is not a material that is very hard to find. But if you need help finding something of the best quality, do not hesitate to get in touch with Superbmelt. We have trusted dealers globally and we can help you get in touch with some of them.

7. How is vacuum casting method different from centrifugal casting method?

The difference between vacuum casting method and centrifugal casting method is not slight. Unless you are a newbie in the industry, you won’t notice the obvious difference that centrifugal casting method is a technique that is used to produce pipes while the vacuum casting method is used to produce other materials.

In centrifugal casting method, molten metal is poured into a cylindrical mold that spins rapidly. It is the same force of rotation that subjects pressure on your molten metal to provide the desired results.

In a nutshell, it is accurate to state that vacuum casting is a process meant for the elastomers, and you can complete the process with our investment casting kit. The vacuum is needed to draw the molten metal into the mold to give you the desired shape or product.

Many experts will say to you that vacuum casting becomes the best method whenever there is an entrapment problem. While that is true, you might also have many other valid reasons to employ vacuum casting technique.

There is also a huge difference between the machine used for vacuum casting, and the one you will need for centrifugal casting. Your centrifugal machine will make use of the weight of the molten metal as well as the centrifugal force available.

A vacuum casting machine, on the other hand, will use a vacuum to suck your molten metal into the available mold. There is the need of a force to help counter the surface tension of your molten metal.

We wouldn’t wish for you to forget that the vacuum casting method is currently the best, which is why you should give our investment casting kit a shot. It leverages the latest technology to give you the perfect finished products you and your clients deserve. If you would like to learn about and benefits of our kit, be sure to check out our main websites and the “Machines” tab.

8. What is investment casting used for?

The process of investment casting can be useful during applications such as making jewelry, precision parts, etc.

Investment casting is a process that comes in handy when you need to make complex-shaped materials that also need tighter tolerances, better surface finishes, and thinner walls that you can get with the help of sand casting.

The thing that makes investment casting stand out from the crowd is the manner in which the mold is created. Some parts of the pattern are made using wax, and then the wax is immersed into a super-fine ceramic.

In the ceramic slurry, there is an alumina and colloidal silica. From there, you will have the mold dried and heated right inside an oven so that the wax melts out to give you a ceramic shell mold that you will then use for casting in our investment casting kit.

Investment casting technique can also be termed as the lost wax process. That name comes from the fact that to complete the process, you will have to melt and get rid of the wax. If you are not sure how to complete this method, we can help you come up with the best parts for your operations.

9. What kind of wax is used in investment casting?

With the help of technology, manufacturers can use a range of methods to craft complex parts of machines and many other things. Investment casting is an old method, but is still used to date. It is a process that involves coming up with a component out of a wax.

Here are some of the waxes you can use in investment casting to create various parts.

Primarily, there are two types of wax you can use to complete this process; they include castable resin and non-castable resin. These are the general types of wax you should always consider using for your lost wax investment casting.

10. What would be considered an advantage of investment casting?

This lost wax casting equipment is designed for casting only small quantity of precious metals (within 300g). It is designed very simple; leaving room for a DIY casting.

This product comes with an inbuilt vacuum pump as compared with other castings kits in the market which doesn’t always come with a vacuum pump.

The automatic intelligent Simen control system (PLC) makes your whole casting process very safe seamless.

The vacuum casting machine automatically stop the machine when an error is detected.

This product is designed fully automated. Both your melting and casting chambers can be flipped automatically during operation. This feature saves you more money it terms of manpower needed to handle your casting operations.

The precious metal casting equipment can cast any of your precious metals in the shortest amount of time possible. This machine is capable of reaching your metal casting temperature (max. temp of 2600℃) in split seconds by a 4.5Kw induction generator

The furnace powerful inbuilt generator speeds up your production process coupled with savings in utility for power consumed

11. How long does the platinum casting process take?

The platinum casting process typically takes about two weeks from start to finish, including wax modeling, investment mixing, burnout, casting, and finishing. Because platinum has a much higher melting point (around 1768°C) than gold or silver, the casting stage itself requires more precise temperature control, though SuperbMelt’s investment casting kit is designed to handle this within a single automated cycle.

12. What do you mean by investment casting machine?

An investment casting machine/kit is the gadget you use to ensure that you get enough pressure or heat to cast your investment without any problem. It should come with an oven where the heating and letting of the wax takes place.

Our jewelry casting machine is a perfect example of a casting machine you should consider using. If you would like to learn more, see the features of our investment casting kit and you will get the gist of what we are talking about.

SuperbMelt vacuum jewelry casting kit (SPB-MVC150) is a top-quality product that is specifically designed to hold metals whose weight do not exceed 300g gold, platinum or 150g silver.

The mini vacuum metal casting machine comes with a quartz and an inbuilt furnace. It is capable of heating up to a maximum temp of 2600℃. The above features makes this product suitable for casting tough metals such as gold, platinum, palladium and silver. etc.

Jewelry casting kit (SPB-MVC150) is equipped with a gas chamber. The gas chamber that releases pressurized inert gases which completely eliminate any form of porosity and oxidation during the casting process. This feature that gives your final cast the touch of class and a feel of quality.

13. What is the temperature for platinum casting?

There is no standard temperature for platinum casting. However, when you begin to cast, you will need a temperature that ranges between 3362 Fahrenheit and 3392 Fahrenheit. Before you begin working, you want to make sure that your machine can produce enough temperature to let you do the work without any hiccups.

Note that you will need the torch to melt your metal and get it into it molten state. For a long time, platinum has proven to be one of the trickiest materials for casters. The truth is, you will struggle to cast it.

Platinum is a very reactive material, which explains why it is also hard to cast. Most of the time, you will notice that it reacts with the crucible.

14. Are there risks involved in platinum casting? How can I avoid them?

There are so many things you are supposed to protect yourself from when dealing with platinum casting. First the ultraviolet rays will be emitted and they might damage our eyes. As such, you need to have eye protection whenever you are dealing with platinum.

You are also supposed to use lenses that are approved by the department of health. You must never use regular lenses or dark lenses because they will never protect your eyes from ultraviolet rays. If you don’t know the right glasses to use, be sure to get in touch with some jewelry suppliers.

15. How do you cast jewelry?

Before using the investment casting kit, the first step is to make your wax mold. You will need a 3D printing machine to make your wax mold. The machine can also help you print the design drawings. The second step involves making the cast plaster. To complete this step, you will need a gypsum powder mixer to help you come up with the plaster moulds that you will use for the jewelry casting.

You should have your burnout plaster mould. You will need it to melt and flow the wax right in the plaster and as well as a plaster mold is obtained.

Now you are ready to commence the melting and casting process. At this stage, you will use the vacuum pressurized casting machine bu customizing it to melt and cast silver, gold, and any other precious metal.

Now the part is ready, but you will need to clean it. Now you need to use the palster cleaning machine to clean the finished product.

Chapter 1:

What Is Investment (Lost-Wax) Casting?

Investment casting — also called lost-wax casting — is the process of creating a metal piece by first sculpting it in wax, encasing that wax model in a heat-resistant investment (plaster/gypsum mixture), melting out the wax to leave a hollow cavity, and then casting molten metal into that cavity. It’s called “lost wax” because the wax model is destroyed in the process — each mold produces exactly one casting.

This method has been used for jewelry making for thousands of years because it captures fine detail that other casting methods can’t reliably reproduce, and it works for both one-off custom pieces and small production runs.

SuperbMelt’s Investment Casting Kit (SPB-MVC150) is built around this exact process, combining a vacuum casting machine with the supporting steps below into a workflow suited to jewelry workshops, small manufacturers, and dental labs casting up to 300g of gold/platinum or 150g of silver per cycle.

Chapter 2:

The Complete Casting Process, Step by Step

2.1, Wax Modeling

Every casting starts with a wax model of the final piece — created either by hand-carving wax, or more commonly today, by 3D printing the design directly in castable resin or wax. The model must match the final piece’s exact dimensions, since the metal will occupy the same space the wax once did.

2.2, Why personal gold miners need a gold melting furnace

Multiple wax models are attached to a central wax stem (the “sprue”), forming a tree-like structure. This lets you cast several pieces in a single cycle. Models must be spaced apart so molten metal can flow evenly to each one without weak points forming between them.

2.3, Investment Mixing & Mold Making

The wax tree is placed in a flask, and investment powder (gypsum-based) mixed with water is poured around it under vacuum — this removes air bubbles that would otherwise create defects in the final casting. Once set, the investment hardens into a solid mold with the wax tree encased inside.

2.4, Wax Burnout

The flask is heated in a burnout oven through a controlled temperature ramp, melting and burning out the wax entirely and leaving a precise negative cavity in the hardened investment — ready to receive molten metal.

2.5, Melting & Casting

This is where SuperbMelt’s Investment Casting Kit does its work: the flask is placed into the vacuum casting chamber, precious metal is melted in the built-in crucible (up to 2600°C), and vacuum pressure draws the molten metal into every detail of the mold cavity — all in a single automated cycle.

2.6, Divesting & Finishing

Once cooled, the investment is broken away to reveal the cast metal tree. Individual pieces are cut from the sprue, then cleaned, polished, and finished into the completed jewelry piece.

Chapter 3:

Why Vacuum Casting Suits Small-Batch and Custom Work

Not every casting job needs a large production line. For workshops producing custom pieces, samples, or smaller batches, a compact vacuum casting kit offers real advantages over larger centrifugal or continuous casting systems:

Lower entry cost: A single integrated melting-and-casting unit costs significantly less than a full production line, making it accessible for smaller studios.
Faster turnaround on one-off pieces: No need to set up a large production run — a single wax tree can go from mold to finished casting in one cycle.
Consistent quality at small scale: Vacuum pressure and inert gas protection prevent porosity and oxidation regardless of batch size, so a 5-piece run gets the same quality control as a 50-piece one.

If your production needs grow beyond small-batch work, SuperbMelt also offers larger casting equipment and full production line solutions — see our [Jewelry Casting Process Solution](https://www.superbmelt.com/jewelry-casting-line-solution/) guide for a complete production line breakdown.

Chapter 4:

Common Casting Defects and How to Prevent Them

Even with good equipment, casting defects can occur if any step in the process isn’t controlled properly. Here are the most common issues and how vacuum casting helps prevent them:

Porosity (tiny holes in the casting): Usually caused by trapped air or gas. Vacuum casting actively removes air from both the investment mixing stage and the casting stage itself, significantly reducing this risk.
Incomplete fill: Occurs when molten metal doesn’t reach every detail of the mold before solidifying. Vacuum pressure helps draw metal into fine details that gravity alone can’t reach.
Oxidation and discoloration: Happens when molten metal reacts with air during melting. Inert gas protection during the melting and casting cycle keeps the metal surface clean and oxide-free.
Cracked investment: Can result from uneven burnout temperatures. Following a controlled, gradual burnout schedule (rather than rapid heating) helps the investment expand evenly and stay intact.

Chapter 5:

Casting Different Precious Metals

Different metals require different handling during the casting process:

Gold (24K, 18K, 14K, K-gold alloys): Relatively forgiving to cast; melting point varies by karat and alloy composition, generally between 900-1064°C.
Silver (fine silver, sterling silver): Prone to oxidation if not protected — inert gas casting is especially important for achieving a bright, tarnish-free finish.
Platinum: Requires much higher casting temperatures (up to 1768°C) and is more reactive with certain crucible materials, making precise temperature control essential.
Palladium: Similar high-temperature handling to platinum, with good resistance to tarnishing once cast.

The SPB-MVC150’s crucible reaches up to 2600°C, giving it the temperature range to handle all four metals within a single piece of equipment.
