The cooling of the surfaces is necessary for the molding of thermoplastic materials because the material must be cooled to the solidification temperature before opening the mold.
The speed with which the mold is cooled influences the characteristics of the final product.
The ISO 293 standard defines the cooling speeds to be used.
The cooling is performed by means of integrated cooling platens and requires the connection to a water source or a chiller.
Control of Cooling speed
The Automatic Press Controller automatically regulates the cooling system according to the temperature and cooling rate set in the moulding cycle.
When the set final temperature has been reached, the platens are opened automatically for the extraction of the moulded part.
