Domestic different supplier performance also has difference, but in ensuring adequate performance at the same time, to control the cost is also a method to solve the problem! 3. Add a moderate amount of punching and shearing of oil, ( Lubricate the punch, cutting mouth to prevent scraps) Cleaning the mold, timely to grinding of punch, sharp, reduce the generation of debris is also effective way! 4. Stainless steel casting mold finish is close friends certainly, brush with wool processing when cleaning up mould surface, often should clean the mold surface and workbench, cannot have iron particles and other impurities in the material or mold surface pressure caused by injury, but reduces the production efficiency.
