TPM pellet mill series ring die is made of high-quality alloy steel or high-chromium stainless steel (German standard X46cr13). It is processed by forging, cutting, drilling, heat treatment and other processes. Through strict production management and quality system, the hardness, die hole uniformity and die hole finish of the production ring die have reached very high quality.
TPM series pellet mill ring die
1.Select high-quality raw materials, secondary steelmaking, degassing billet;
2.Ring die material: X46Cr13 / 4Cr13 (stainless steel), 42Crmo / 20CrMnTi (alloy steel) or other custom materials;
3.Imported gun drill and multi-station drill, one-time forming die hole, high-quality finish, production of feed, beautiful appearance and high output;
4.Select the combination of vacuum furnace and continuous quenching furnace to ensure long service life;
5.According to the principle and requirements of the customer to design compression ratio and strength;
6.Microscopic examination to ensure product quality;
