As we know, choosing a suitable material for injection mold tooling is important for the overall production, including mold service life, economy, etc.

My company usually choose steel to make the mold, like P20 steel, #45 steel, H13 steel, etc. I heard someone may use aluminum as the mold materials. We tried aluminum before but the aluminum is more limited. It is lower hardness and easy to wear out after a few thousand of production cycles.

All in all, if considering the small scale production, aluminum is a cost-effective choice and steel mold is more suitable on mass production. Which material is you guys prefer? Which steel, or aluminum?
