HIGH-SPEED STEEL EJECTOR PINS

Material :SKH51 Hardness :59-61HRC.

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.

PARTICULARLY NITRIDED EJECTOR PINS

Material :SKD61 Internal

Hardness :40-45HRC Surface

Hardness :HV900 above.

pin dia.:2.0-25mm ,

length:below 1000mm ,

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

RECTANGULAR EJECTOR PINS

Material :SKH51Hardness :59-61HRC

The flat part may be machined to 0.3mm thickness with 0.005mm precision.

 The flat part shall be abraded after being subject to heat treatment so as to ensure the consistency in its internal structure and result in high tenacity and non-deformation.

EJECTOR SLEEVES

 Material :SKH51 Hardness :59-61HRC

Length:within 300mm

Coaxiality :0.01mm

Max. precision: 0.005mm.

Material :SKD61 Internal Hardness :38-42HRC

 Surface Hardness : HV900 and higher Length: 1000mm and lower Coaxiality:0.06mm

Max. precision 0.01mm

The internal holes of these products have been subjected to precision grinding and rigid coaxiality control to ensure proper fitness with ejector pin and core as well as high compatibility.
