Why is aluminium considered suitable for smaller runs only out of interest?
- mcphage 9y agoAluminum is softer than steel, so the mold wears out quicker—the models lose details.
- RyJones 9y agoand it's much cheaper to work. If you're only doing a couple thousand moldings, you don't care as much about mold life
- anfractuosity 9y agoAh cheers that makes sense. One thing I was wondering would they use stainless steel for moulds, to prevent them rusting?
- TylerE 9y agoNope, "real" molds are made out of tool steel. Corrosion isn't really a problem since machines are typically stored indoors.
