Jewellry Double Head Rolling Mill

Jewellry Double Head Rolling Mill

CDOCAST This heavy-duty dual rolling mill is engineered for maximum efficiency and precision in metalworking. Constructed from high-grade steel, its robust frame ensures stable, long-lasting performance even under the daily strain of processing thick or hard metals like gold, silver, and copper. The fully adjustable rollers provide exact control over thickness and texture, making it an indispensable tool for jewelers, blacksmiths, and crafters who require professional, bubble-free finishes for everything from handmade jewelry to intricate art pieces. Despite its powerful capabilities, the mill features a compact, workshop-friendly design that fits comfortably in both professional and home studio settings.
The core of this mill’s efficiency lies in its dual rolling heads, which operate simultaneously to streamline the shaping process. A craftsman feeds a metal sheet or wire into the first set of rollers, which begins the initial shaping and thinning. Instead of removing the metal and resetting the machine, the material is fed directly through the second rolling head in a continuous motion. This second pass further refines the metal, achieving the desired final thickness, smoothness, or pattern with exceptional precision. This seamless, two-stage process effectively halves the manual handling time, allowing for high-volume production and consistent, professional results with every operation.
Beyond its efficient workflow, this machine offers remarkable versatility for a wide range of applications. It is perfectly suited for flattening and shaping precious metal sheets, reducing wire thickness smoothly, and creating custom textured patterns. The precision control allows for fine-tuning every detail, ensuring repeatable accuracy across multiple projects, which is crucial for both custom design work and industrial metalwork. This combination of power, adjustability, and consistent performance makes it an ideal investment for anyone seeking to enhance their crafting capabilities, from professional jewelers to dedicated DIY enthusiasts.

Jewelry Wire Rolling Machine

Jewelry Wire Rolling Machine

The Jewelry Wire Rolling Machine is a machine specifically designed for processing precious metal wires such as gold, silver, and platinum. Through multiple rolling processes, it gradually compresses metal billets (such as ingots and thick wires) to a target diameter (such as 1mm to 5mm) and improves the surface finish and mechanical properties of the wire.

Metal Strips Rolling Mill

Metal Strips Rolling Mill

The Rolling mill is an industrial machine used to process metals (such as gold, silver, copper, etc.) into finished or semi-finished products of specific shapes and sizes through a rolling process. The core principle is to apply pressure to the metal using one or more pairs of rotating rollers, causing it to plastically deform, thereby changing its thickness, width, or cross-sectional shape.

Rolling mill

Rolling mill

CDOCAST Jewelry Rolling Mill is an equipment that realizes the precious metal rolling process. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough.

Our rolling mills are capable of extruding wire and plate of various sizes and can be customized according to different dimensional requirements.

Metal Wire Rolling Mill

Metal Wire Rolling Mill

CDOCAST metal wire rolling mill machine is mainly suitable for rolling pure silver wire, K gold wire, pure gold wire, and silver alloy wire, copper wire, copper alloy wire…etcThe metal wire rolling mill is mainly composed of machine body, wire straightening mechanism, rolling mechanism, take-up mechanism, cooling and lubrication system, transmission system and electric control part.

The body is welded with steel plate and section steel, and the pinion box is cast. The transmission part is driven by helical gear and spiral bevel gear. The roll is made of special alloy steel and processed by the heat treatment process, which has the advantages of super wear resistance and impact resistance. The rolling part is cooled and lubricated by spraying. The power adopts frequency conversion stepless speed regulation.

Multiple roll boxes are arranged in parallel on the machine body. Each roll box has two pairs of longitudinal and transverse rolls. The two pairs of rolls are distributed horizontally and vertically respectively. The line diameter after rolling is gradually reduced in proportion. The compression rate is designed according to the material extension characteristics. The compression of each pass is equal. When the wire passes through the roll, the material is pressed by the rotating roll, The reduced wire rod is extruded from the roll, and finally, the wire rod is transported to the receiving tray through the traction device to realize the rolling of the wire rod.
