Wear-resisting Heat resista Steped ejector sleeves Used SKD61
Materials for Plastic Injection Mold
Description
The ejector sleeves is a kind of plastic mould accessories used in
conjunction with ejector pins, it looks like a hollow ejector pins.
When there are circular through-holes or blind holes in the
injection products and it must be ejected, the ejector sleeves
should be used.
Materials
SKD61 has good toughness and high temperature fatigue resistance.
It can withstand temperature fusion. It is suitable for long-term
work at high temperature. It has good cutting performance and
polishing performance. It is the best material for making ejector
pins and cylinders.
SKD61 is also suitable for the manufacture of high-volume plastic
molds. The nitriding treatment can obtain a good hardened layer
structure on the surface of the mold, and improve the wear
resistance and corrosion resistance.

Customized
If a custom-sized product is needed, please let us know the
following values, and anything else we have done for you.
Attention
It is necessary to spray antirust agent to prevent rust during the
