Regular mould maintenance can help your mould to last longer, to run with less interruptions, and will save you time, money, and frustration in the long run. The amount and frequency of maintenance is determined by several factors, (Mold Material) Aluminum or soft tools will suffer wear and tear in a shorter period of time than tools made of conventional tool steel.
(Part material) Plastic materials that have fillers are especially abrasive and will tend to wash away the mold steel after thousands of cycles. Also plastic with a high melt temperature causes more wear than those with low melt temperatures. Higher melt temperatures expose the mold to more heat and enhance material wear. Some materials give off excessive of residue or even corrosive gasses requiring more regular mold cleaning.
