Diamond Coating Mould:a new mould is obtained by Chemical Vapor Deposition (CVD) on the inner hole surface of the die with cemented carbide (WC Co) as the substrate.The diamond coating is precisely ground and polished to obtain a new mold.
The product has the toughness of cemented carbide mold,the hardness and wear resistance of natural diamond,and the inner hole is bright and the friction coefficient is low Long service life.
Wire drawing is done by passing the metal wire through the hole of the Wire Drawing Die, and applying a pulling force to the wire at the exit side of the die. The wire is contracted and squeezed in the die cavity and gradually becomes thinner, and its speed increases near the exit of the die hole. Since the volume of the wire is constant, the decrease in cross section makes it stretched. In the center, there is a hole of a certain shape, such as round, square, octagonal or other special shapes. When the metal is pulled through the die hole, the size becomes smaller and even the shape changes.
The best material depends on the wire you draw and the quantity you draw. Contact us to help you choose the most economical solution and reduce the total cost of ownership of your drawing dies.
Top Quality Wire Drawing Moulds Compacting Copper Aluminum Wire With CVD Diamond Coated Wire Bunching Drawing Dies
CVD Diamond Wire Drawing Dies the bundle and strand moulds are used to guide and / or organize the wire through the bunching machine and stranding machine,the winding drum of the double and single twist bunching machine is inside the machine,and the mold is fixed at the entrance of the machine to collect the wire.
In some cases,the die is fixed to the front of the winding drum inside the machine to regulate the wire,and the strand mold of the tubular and basket strander is inside the machine to guide and concentrate the wire.
Process and technology:
Targeted pretreatment process:to make the coating and the substrate closely combined
Micro diamond coating:excellent wear resistance
Surface nano diamond coating:excellent surface finish and low friction coefficient
Optimization of pass design by computer simulation
The Wire Drawing Die is a very important and consumable product used by various metal wire manufacturers to draw wires. The application range of wire drawing dies is very wide, mainly used for drawing straight and difficult-to-machine objects such as bars, wires, wires, pipes, etc., and generally suitable for drawing processing operations of metal and alloy materials such as steel, copper, tungsten, molybdenum, etc. . Since the cost of the wire drawing die can reach more than half of the wire drawing cost, how to reduce the consumption cost of the wire drawing die and increase its service life is the primary problem that metal wire production units urgently need to solve.
Wire Drawing Dies have a wide range of uses, such as: high-precision wires used in electronic devices, radars, televisions, instruments and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires, all of which are made of diamond It is drawn by a wire drawing die. Due to the use of natural diamond as the raw material, the diamond wire drawing die has strong wear resistance and extremely long service life.
