Ejector sleeve DIN and JIS quality skd61

Specialized in making DIN and JIS skd61（FDAC） ejector sleeve, stable quality in low cost.

Hollow ejector pins are also named ejector sleeves or ejector bush,were mostly used in hot die casting tools under high temperrature 650℃ conditions, cylindrical ejector pins with a cylindrical head made of hardened and nitrated 1.2343 material  Ejector Pins  full body are through-hardened with an Vacuum  ion nitriding surface improve surface hardness from HV990-1200(HRC65-70).After through such hea-treatments, the surface strength, hardness, and wear resistance can be effectively improved, and the product life can be prolonged too much.

SS ejecotor pin sleeve mosted used in medical industries,it ws made from 420 Stainless Steel 50-52 RC thru hard; Superior corrosion resistance compared to standard ejector pins.
