1. SKD61 hot-working die steel, can produce high-end very durable gate sleeve, hardness can reach 48-52HRC. The gate sleeve made by SKD61 has the characteristics of high temperature resistance

which leads to the failure of the die due to wear. So the wear resistance of materials is one of the most basic and important properties of dies. Hardness is the main factor affecting wear resistance.

1.In plastic moulds, separating products from moulds is also the most commonly used. 2.Cemented carbide thimbles, such as tungsten steel thimbles, can be used to pass through longer and finer holes.
