Carbide Punch Bar Tungsten Steel Round Bar Custom Made Production


The production of stamping dies in industrial production is a continuous progressive state, especially for high-precision, high-demand stamping operations. The usage quality becomes a priority. In the cold stamping process, the material is processed into parts by stamping dies. Stamping is a pressure processing method that puts pressure on material by means of the die mounted at room temperature to cause separation or plastic deformation to obtain desired part. It is commonly used in industrial production. Stamping dies are indispensable process equipment for stamping production, also the technology-intensive products. The quality, production efficiency and production cost of stamping parts are directly related to the precision and design of die parts. As the industrial tooth, cemented carbide, with the advantages of the high strength, high hardness and high wear resistance, are the core parts of precision machining operations. For the hard alloy punching rods in precision die stamping operation, our company provides customer-made production according to the customer's drawings.

Technical parameters:

Carbide punching rods are made according to the customer's drawings. We can provide high-performance and high-precision punching rods. The physical parameters and tolerances are as follows:

1. CO content: 10% ~ 12%

2. Density (g/cm³): 14.0 ~ 14.5

3. Hardness: 89 ~ 92.0 HRA

4. Grain size: 0.6 ~ 1.2 um

5. Bending strength: 4000MPa

6. Modulus of elasticity (GPa): 490.

7. Thermal expansion coefficient 10-6/0C: 5.4.

8. The dimensions and specifications of the carbide insert pins are customized according to the drawings, and the precision requirements can be ±0.001.


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.
