日本大同廠生産大同牌(有托)頂針,大同牌耐熱頂針係由特殊鍛模鋼製成.其頭冠部因經過鍛造工程,再經過退火處理等加工工藝,使頂針不易毀損.頂針本體表面經過氮化處理後,其硬度達HV1,000-1,200度(大約等於HRC65°-80°),且內部硬度達HRC36°-40°,因此韌性極佳.頂針本體表面則施以精密的磨削加工外,再經過磨光處理,因耐表面整修極美.它可適合於保持精巧的模具及壓鑄模具的精密度,同時能提高模具模具的使用壽命.
Daido HOTWORK EJECTOR PINS are made of hot alloy tool steel. By nitriding,thebody of the pin has surface hardness of850～1,100 Vickers(approx.65～80HRC),while having the inside hardness of about 40HRC. The pin head is formed by hot forging and therefore the inside structure flows along the shape. Pin body is precision ground.
