Grewin Tungsten Carbide Tools Cold Forging Dies
Tungsten carbide Fasten punching mould has two definition: cold forging and hot forging.
it used on the cold forging machine, making the materials cutting, reforming, forming to the mould.
we use the advanced HIP sintering technology which makes the density perfect. It can make the working life longer and the punching resistant improves.
Advantages
1.The raw materials were choose strictly from the first step, the size of the WC is medium and course and the cobalt powder is imported one.
2.The advanced technology and machine will be used on low pressure sintering.
3.The HIP sintering will brings better density and strength, especially on working application is obvious.
4.special powder pressing technology with HIP sintering, reducing the porosity, improve the density and catachrestic.
5.we choose the suitable grade according to the exactly usage.
