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.
Carbide insert pin, also known as tungsten steel insert pin and hard alloy punching pin, is made up of hard alloy rods, with high precision, high hardness and good bending strength, suitable for hardware and electrical processing industry, generally used for punching on stamping dies to separate or plastically deform the material to obtain the required parts. Due to its advantages of high hardness, long service life, corrosion resistance and no rust, it is widely used in industrial machinery manufacturing and processing.
As a precision mold, the consistency for the carbide insert pin is a key factor, which will directly affect the life of the mold and the dimensional accuracy of the product. It is not only the rough processing of carbide rods but also the fine-size processing of hard alloy punches. It is essential to strictly control the dimensional tolerance requirements and the consistency of mass production.
The carbide insert pins of our company use high-quality grade alloy materials.
The physical parameters 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 | The precision requirements can be ±0.001. |
Our company is specializing in producing and manufacturing hard alloy insert pins for precision mold customers. It is used with electronic ceramic injection molds. The precision requirements are very high, and the perfect consistency of products is the primary standard of this set of products. The tungsten carbide punching pin equipped in electronic ceramic precision mold is used in large number, and each insert pin is required to maintain good consistency. This requires that the finishing process must strictly control each processing procedure. Our company can produce the hard alloy insert pins according to the requirements of the precision mold manufacturer. The consistency of the products can be guaranteed, and the tolerance requirements are +0.002. The finish of the punch needles is required to be 0.2, which meets the highest requirements of applications in electronic ceramic injection molds.
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.
