How to choose the steel for thin wall molds?
In view of high speed high pressure injection, it need to use more than HRC42 hardness steel to guarantee long time mold life. Moreover ,box's raw material is usually clear transparent,this also determines the need for a high polishing steel.
Therefore, based on the above characteristics,usually, we recommend using S136 steel with HRC43-45 hardness.
However,H13 steel with vacuum hardened also have HRC43-45 and it can be the second choice for economic invest.
