plastic molds componets

Material :SKH51 Hardness :59-61HRC Shaft Diameter Φ0.3-25mm,Length :within 500mm. Super precision shaft diameter reached 0.002mm，precision 0.005mm,nomal 0.01mm。After our concentrated studies and we are the first manufacturer that exploit and use the high speed steel to make the ejector pin in the world .This kind of ejector pins are of high hardness ,good performance in tenacity, wearability and heat-resistance .It suits the precision molds .It can increase the service life substantially ,especially the control of precision mold's heat deformation .
