很多刀片由于结构较为复杂，需要流线线条，或者比较厚，无法用切割或冲压直接完成加工，所以选择精密铸造成型。Some blade structure is complex and cannot be cut or stamping processing, so choose precision casting molding.

产品打样，小单量的产品，未定型的产品试产，在不制作冲压模具的情况下制作产品，大多采用线切割或激光切割外形制作。 Product proofing, single product quantity is little, not production stamping die, use "line" or "laser cutting production.

产品订单量较大的产品，制作五金冲压模具，用高速冲床冲压产品外形。Product orders for larger products, production of metal stamping mold, with high-speed punch stamping product appearance.
