Avoiding mould condensation in plastics processing

Mold condensation

Molud condensation is a fairly big issue when the mould water approaches the environment dew point. Condensation appears on the moulds and affects the surface quality. Often the only solution to the problem is increasing the mould cooling water temperature. This results often in bigger cycle times, quality problems due to the different shrinkage etc.

Solution

Creating an over pressure of ‘dry’ air inside the machine, in such way that the dew point inside the machine is brought below the actual dew point, thus preventing mould condensation.
