Die ejector use
1). In the plastic mold, the product is separated from the mold, is also the most commonly used;

The types of plastic mold thimble are: , dome pin, holder pin, standard ejector pin, non-standard ejector pin, etc.
Plastic mold thimble materials are SKH51, SKD61, SKD11, 65Mn, etc.
SKH51 thimble toughness better than SKD61; SKD61 thimble can withstand high temperature 1600 °C, SKD61 thimble surface after nitriding treatment can be very good to improve the thimble wear resistance, 65Mn thimble because of its poor quality, quality is more brittle easy to break, large Some plastic molds have not been assembled and used 65Mn thimble.
