What Is The Most Important Role Of Dies In Cable Industry?

With the development needs of the cable industry, the diversification of cable product types, and the increase in customers’ special needs for cable products, the types and requirements of cable molds have gradually increased.

At present, the types of molds involved in the cable industry mainly include drawing and stranding molds;Press molding die, cabling die;extrusion molds, etc.In particular, according to different materials and applications.

SFD divides wire drawing dies into different types

such as PCD wire drawing die, carbide die, CVD coating die.

In the cable industry, drawing and stranding molds are important components of wire molds, and their types, performance, and application are crucial.This type of mold is usually divided into round mold and mold, and the commonly used wire mold materials include diamond mold, hard alloy mold, polycrystalline mold, etc.

Diamond molds have the highest hardness and wear resistance, and are suitable for drawing small-sized monofilaments;Hard alloy molds have replaced the previous tungsten steel molds, boasting excellent wear resistance, polishing quality, and corrosion resistance;

Polycrystalline mold is currently the most commonly used mold wire mold, although it has good wear resistance, its surface smoothness is not good;Tungsten steel molds are suitable for aluminum drawing, but they have a shorter lifespan and a less smooth surface.

Diamond mold, also known as diamond, has the highest hardness and wear resistance, but is relatively expensive. In wire drawing, it is generally used to pull small-sized single wires, such as those with a diameter of 0.40mm or less.	In stretching production, tungsten steel molds used in the past have all been replaced by hard alloy molds. Compared with steel molds, hard alloy stretching molds have better wear resistance, good polishing performance, lower adhesion to the processed metal, lower friction coefficient, higher thermal conductivity, and high corrosion resistance.	Also known as artificial diamond, is currently the most commonly used wire mold. It has wear resistance, but its drawback is that the surface of the produced product is not smooth.	Currently commonly used for aluminum drawing and with a short service life, it is generally used for bridge molds. Tungsten steel molds have average wear resistance and low price, but their strength is not suitable for copper drawing, and the surface of the drawn wire core is not smooth.

In wire drawing and twisting molds, the design of the inlet area and lubrication area is particularly critical. The next article will provide a detailed introduction. Please stay tuned!
