Production technology
Ingredients (Main ingredients :WC+TiC+TaC+Co+VC+……) → Full mixing → crushing → Drying → Adding molding agent after sifting → drying → sifting mixture → Mixing granulation and pressing → molding → low pressure sintering → Blank after sintering → Inspection (non-destructive ultrasonic inspection)→ blank dimensional accuracy inspection → Electric discharge machining (or wire cutting molding)→ rough grinding → fine grinding → polishing → Inspection → Marking → Packaging.
Product use
Its application field is very wide, because it has the characteristics of acid and alkali resistance, no rust and long service life, the pharmaceutical industry selected its punch for the production of stamped tablets.
