Guide sleeve, as an essential part of the mold, co-operate with the guide column, its wear resistance and toughness have certain requirements. Normally we will choose different materials depending on the mold, common materials include carbon structural steel, carbon tool steel, alloy tool steel,alloy structural steel.They must have good cutting performance, and strong wear resistance.
In order to obtain good usage tool life, we usually use heat treatment to improve the performance. Heat treating is one of the most important process for producing mold, and it will have high hardness, large allowance after heat treating. And we need to choose the most suitable cutting tools depending on all factors.
