Special Punch Tooling
Sandi is committed to offering high quality punch components to extend the life of mold tooling and reduce production costs.
All standard or punches are manufactured with the highest level of tool steel and carbide,no broken after 100M punching and no deformation after 200 punching ,the roughness of the punch tooling can reach Ra0.4 ,the tolerance can reach ±0.002mm. we have strict dimension control system to ensure that the qualified rate of 99.8%, all special punches which did not meet the requirements of the drawings will turn back to re-work for free until satisfied

HSS Special Tooling
Supported with heat treatment and ultra-cryogenic processing technology, the special tooling performance is greatly increased 30% in hardness and wear resistance
SKD11 Custom Punch
Our customized punch is mainly suitable for die stamping manufacturing, SKD11, SKH51, ASP and other commonly optional material for punching working in various stamping conditions
Tool Steel Punch
The punch is matched with the dies when stamping working,the clearance between them is very small for some precision molds.We use mainly CNC turning and cylindrical grinding to ensure all dimension in good tolerance.
