Rolling Mill for Jewelry Making
Introduction of Rolling Mill for Jewelry Making
Rolling mill for jewelry making is a machine that can press the thickness of sheet metal through a one-shot rolling process. It is widely used in industries dealing with metals such as gold, silver and copper, such as jewelers, metal processing plants and craftsmen.
The continuous rolling mill consists of 5-6 sets of pressure rolls, which apply pressure to the metal and achieve its desired shape and thickness in one go. The roll gap can be adjusted between 5mm-0.5mm to produce various metal sheets for processing bracelets or rings.
This equipment has greatly improved the shortcomings of ordinary electric rolling mills that require two workers to repeatedly press and roll, and can complete sheet processing faster and more efficiently, saving more labor costs.
How to Use a Rolling Mill for Jewelry Making
The continuous rolling mill has increased the level of automation to a greater extent, with 5 to 6 groups of pressing rolls working at the same time. Controlled by intelligent PLC, gold, silver, copper, tin and other metals within 5mm can be pressed at one time, so how are the sheets used for rings, bracelets and other jewelry produced through a continuous rolling mill?
- Metal Material Measurement
To measure the size of metal materials, taking gold as an example, the thickness must be controlled within 5mm and the width within 60mm.
This step is to ensure the suitability of the material and avoid damage to the machine due to size errors.
- Parameter Adjustment
Adjust the pressing speed, pressing gap, forward and reverse direction of rollers, etc. through PLC. Adjust according to the size required by the product.
- Feed Preparation
The material is fixed at the feed port, and the material is sent into the press area through the remote control device. Remote operations can avoid operational risks.
- Material Collection
Install the automatic winding device, and when the material is output from the discharge port, it can be fixed on the automatic winding device to realize the whole process of automatic winding without manual collection.

Details of Rolling Mill for Jewelry Making
- Continuous Rolling Process
This machine is designed for continuous operation of 5-6 sets of pressure rollers, which means that one machine no longer needs two workers to operate, the sheet forming time is shorter, and labor resources are saved.
- High-precision
The pressure roller is made of high-hardness hrc63-degree steel, which can achieve accurate measurement, flatness and consistent results at one time.
- Electric Operation
The mill is driven by electric power, PLC operation is more convenient, and the speed can be adjusted, which reduces the required manual labor.
- Adjustable Rollers
The rollers can be adjusted to fit metals of various thicknesses, and it is more flexible to solve the size required by most jewelry products.
- In and Out Material Security
Feed through the remote control panel, you only need to press the button, and the material collection is also through the automatic winding device, without manual feeding and discharging, which is safer and more efficient.

Continuous rolling mill is used for forming metal sheets such as gold, silver, copper, tin and etc., pressing flat and uniform jewelry processing materials. Like hollow bracelets, rings, etc., the materials need to be pressed into thin sheets by a tablet press, and then used for later cutting and welding for pipes.
