Mould Dehumidification

Mould Dehumidification

Mould Sweating is undesirable, causes rusting and severely affects the life of expensive mould and machine bed, The injection Moulding process involves injection of plastic melt in the mould and cooling the melt in the mould to take the desired shape. Chilled water is used for quick cooling of plastic melts and to reduce the cooling time in a particular cycle. However, when chilled water is used for cooling of moulds, the moisture present in the air in the vicinity of chilled mould surface condenses, leading to the formation of water droplets on the mould surface (Mould Sweating).

Mould Sweating is undesirable, as the condensed water droplets tend to drip on the machine bed and seep into the mould, which causes rusting and severely affects the life of expensive mould and machine bed. Further, condensation in the core and cavity of the mould will lead to defects in the moulded component
