Standard Size SKH51 High Speed Steel Mold Ejector Pins for Plastic
Injection Molding
Description
Mold Ejector blades is commonly plastic mold parts, used to separate products from the
mold. It is required to have high hardness, good toughness and hard
breaking.
Materials
High speed steel SKH51, SKD61, SKD11 and 65Mn were usually used to
make the ejector pins. The toughness of SKH51 is better than SKD61,
but SKD61 can withstand high temperature 1600℃, and if it was after
surface nitriding treatment, the wear resistance can be improved
very well. Because of its poor quality and brittleness, the
application of 65Mn is becoming less and less in ejector pins
industry recently.
Standard Size
According to HASCO standard, we have the following standard sizes
of thimbles in stock, generally can be shipped within 3 working
