Ejector Pins and Ejector Sleeves are extensively used in ejecting out components from opened moulds in plastic moulding and die casting operations. These tools are manufactured from hot die steel (HDS) of H13 quality. HDS H13 steel is best suited when the operating temperature exceeds 180ยฐ centigrade. The ejector pins and ejector sleeves are hardened, ground, tempered and nitride. Their hardness is maintained between HRC 48 to HRC 52, and the surface hardness is maintained at HV950. The company also offers round piercing punches, ejector pins, ejector sleeves, blind hole core pins, stepped pins, die buttons, HSS round tools bits, drill jig bushes and punch guide bushes, etc.
Thickness of nitration case: 0.02-0.05mm, After surface treatment, the product will have an anti-wearing and corrosion-resistant surface with fairly high hardness and a body with fairly low hardness and high tenacity, applicable for molds operating under high temperature
The minimum diameter of pin to be machined is 0.2mm, with the maximum precision up to 0.002mm.
Further machining such as chrome-plating and character-engraving is allowed for working end.
Unremitting efforts in research has made us the pioneer to make ejector pin with high-speed steel which is of high hardness, high ductility, high grinding resistance and high heat resistance, better for precision mold, capable of increasing the service life significantly, particularly being very effective in controlling the hot deformation for precision mold.
