Introduction:

Cemented carbide is a mixture produced by metal carbide powder and cobalt.

Tungsten carbide, titanium carbide, tantalum carbide and vanadium carbide are usually use to improve the carbide properties, thus cemented carbide has high hardness and high wear resistance.

Alloy is a kind of high-efficiency tool material. It is made up of the mixture of high-melting-point and high-hardness metal carbide powder and binder and then pressed into workpiece of various shapes by powder metallurgy method, therefore, to ensure that the cemented carbide has certain hardness, strength and toughness.

Advantages:

As a cemented carbide manufacturer in Zhuzhou, we provide high-precision and high-performance punching rods for stamping dies, especially for carbide punch rods used in progressive blanking dies.

The high-quality alloy round bar is selected as the base body, which has the properties of high precision, high hardness, good bending strength and high degree of finish.

It is suitable for industry punching, such as for the production and processing of electronic ceramic injection molds, metal punching processing and so on. And it used for separating or plastically deforming the material to obtain the required parts.

The hard alloy punch rod produced by our company has the characteristics of high hardness, high precision, perfect consistency, long service life, corrosion resistance and no rust. It has become the most ideal punching tool for mechanical stamping processing.

From raw material production to finished product processing, the hard alloy insert pins of our company are complete and perfect. The whole project is based on the cemented carbide production process. The ingredients are mixed thoroughly → pulverized → dried → sieved, then added to the forming agent → re-dried → sifted to obtain the mixture → pressing the mixed granulation → forming → low-pressure sintering → sintered blank → inspection (non-destructive ultrasonic testing) → blank dimensional accuracy inspection → EDM (or wire cutting) → rough grinding → fine grinding → polishing → inspection → marking → packaging. Mass production of carbide insert pin requires product consistency, which directly affects production efficiency. Carbide punching pins produced by our company, whether it is custom-made or mass-produced, always controls each processing procedure to ensure the consistency of the carbide insert pins.

The physical parameters are as follows:
