The most common alternative to aluminum milled molds is steel. Steel molds are strong, durable, and corrosion-resistant, but they have a lower melting point than aluminum. This means that steel will require a higher temperature to melt. Steel also requires more force for pressing and can be harder to work with due to its weight
Wood is another alternative material for making molds. Wood is typically used for smaller, lighter applications where the weight of metal would be too much. Wood has a low melting point, so it can be difficult to work with in some applications because the wood will warp when heated above its melting point
Another alternative to aluminum milled mold is plastic injection molding (PI). Plastic injection molding (PI) is a type of blow molding process that uses plastic as the material for injection into an open cavity or cavity block made from another material like aluminum or steel.
