Ejector Punch Pins
Ejector punch pins refers to the metal parts on the stamping die of mechanical tools, also known as punching rod, punching needle or punch pins, it is installed on the stamping tooling for continuous punching operation, marking the processed material separated or plastic deformation, so as to get the required finished or semi-finished products.
We specialized in the design and manufacturer of carbide or steel ejector pins for different requirements, our professional engineers designers can work with you ,using your requirements and preferences to provide you with quality replacement parts to the most demanding specifications.
Supported with heat treatment and ultra-cryogenic processing technology,the pins material performance is greatly increased 30% in hardness and wear resistance .
HSS Punches Pins
We have strong ability to produce all kinds of HSS ejector punches for metal stamping tools or other molds.its tolerance can reach +/-0.001mm.
Ejector Pins with Coatin
All ejector punch pins are manufactured with the highest level of carbide,DLC or TiN coating are available.
