COOLING IN WATER

Cooling in water of moulded plastic materials to grant the dimensional stability of the components and their conformity to the reference sample.

COOLING IN WATER

The device for cooling in water uses a variable number of blocking dies and the plunging of the article in water. The cold water prevents the thermoplastic material from shrinking or getting deformed.

After being removed from the moulding machine, the article is placed on some dies that block it on various points of its surface. The blocking dies hold the article in the crucial points to maintain the specific dimensions. While held in this way, the article is plunged in cold water to cool down and to keep the dimensions that conform with the reference sample. The water temperature and the length of the immersion in water vary according to the thermoplastic material to cool.

The articles that can be cooled in water can be produced by means of injection moulding, extrusion moulding, compression moulding, blow moulding and suction 2D/3D (2k).

Among the articles that have been cooled in water by the machines of GS Finishing Machines the following can be listed: pipes to intake the dirty air and clean air from the engine and filling pipes for tanks.
