We will use low-cost P20 soft-tool-steel or 7075 Aluminium and make just the core, cavity & ejector plates and insert these into a Master Unit Die (MUD) base. We will not add cooling ways or other costly trimmings to the tool. This is as basic as it gets and is similar to many of the ‘rapid injection molding’ services offered elsewhere in the World today. For polished or high-gloss parts we will normally use NAK-80 a polishing stainless steel.
