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.


Metal Extrusion Machine

Cdocast metal extruding machine is the latest multi-purpose four-column horizontal machine developed by our company, which is controlled by microcomputer PLC.
This metal extruder is mainly applicable to:
1. It is applicable to the extrusion of various specifications of copper and copper alloy wires (rods).
2. It is applicable to the extrusion of silver and aluminum alloy wires (rods) of various specifications.


Power; 3phase,380v

Appliction:gold, silver ,copper

Final products: rod, sheet, bar,wire,plate..etc



Water chiller

Air-cooled water chiller is one of the models of water chiller, the normal temperature water will be cooled to a certain temperature through the compressor of the chiller to strengthen the cooling mold or machine, as a stand-alone use, the radiator is a built-in fan, there are three interconnected systems: refrigerant circulation system, water circulation system, electric automatic control system.

The air-cooled water chiller model is compact, small and movable. CDOCAST water chillers are mainly used in the cooling of intermediate frequency furnace and continuous casting, mainly applied in the process of lowering the temperature of the power supply furnace, to protect the whole equipment from the damage of high temperature. Sometimes, it is also used in the cooling of semi-products cooling.

Laser Marking Machine

The principle of laser marking machine is to use a laser beam to make permanent marks on a variety of different material surfaces.

The effect of marking is to expose the deeper layers of material through the evaporation of the surface material, or to “engrave” the marks through the chemical and physical changes of the surface material caused by light energy, or to burn away part of the material through light energy to reveal the desired etching pattern or text.


Hydraulic Logo Stamping& Blanking Machine

CDOCAST  hydraulic logo  stamping  machines are mainly used in gold and silver bar production lines for embossing logos and designs on gold and silver bars, CDOCAST can also provide dies designs for logo stamping Adopt four-column and three-plate structure, the planar accuracy of the movable plate fish table is high, the four-axis precision linear self-lubricating guide sleeve is controlled, and the vertical accuracy is high

XRF Gold Analyzer

CDOCAST XRF Gold Analyzer  isdesigned for precious metals and jewelry detection. The measurement process only takes a few seconds; the measurement result unit is displayed as% and carat.

xrf gold tester can also be used to detect coatings and non-standard alloys. The instrument can be operated using the embedded display screen or the CDOCAST software installed on the PC. CCD camera is applied to achieve precise sample positioning. Automatic variable collimator, required measuring point size is free to choose


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.

Hydraulic Press For Minting

Cdocast hydraulic press is mainly used to suppress the patterns aon gold and silver coins. The hydraulic press can be divided into four column and frame type hydraulic presses. According to different customer requirements, the corresponding equipment is selected.The tonnage of our hydraulic press ranges from 10ton to 1000ton, and can be customized. According to the complexity and depth of the patterns to be pressed for coins, our engineers will choose the most suitable  hydraulic presses for your needs.

Wire Drawing Machine

The wire drawing machine usually changes the diameter or shape of the wire from the disk to the disk through the wire drawing die to move the required diameter or shape. The wire must be lubricated when it enters the drawing die, and the drawing die has a dedicated cooling (usually water-cooled jacket cooling). The closing machine provides power.

Graphite Crucible

Graphite crucible, with its special advantages and Plasticity, is widely used in the smelting area, e.g. gold smelting, silver smelting, aluminum smelting, and cooper smelting in metallurgy, casting, machinery, chemical and other industries.
