This product is divided into two categories, high quality alloy steel, high chromium stainless steel. By forging, cutting, drilling, such as heat treatment process is made.

My company through the strict production management and a series of technical improvement, make the product quality especially in the hardness of ring die, die evenness, die finish has reached the domestic advanced level. Not only increase the service life of the ring die and raised its view of granular material extruded additional texture, make the particle surface is smooth, uniform particles, powder feed rate is small.

Alloy steel series:

With high quality alloy steel as raw materials. This series of ring die of high strength, surface hardness of HRC - 61, hardening layer depth of 1.2 mm, with strong resistance to wear; In the process of using hardness difference less than HRC3, put an end to the crack, metal shed and the phenomenon such as eccentric wear, greatly improving the service life of ring die.

Stainless steel series:

With high chromium stainless steel as raw materials. This series of ring die adopts integral vacuum quenching process, the hardness greater than HRC50, has high wear resistance and corrosion resistance. Especially suitable for high compression ratio of the feed.
