The Composition and Function of each part for pvc Extrusion Mould:

Configuration of Mould



Dies head

Produce continuous,stable,homogeneous profile

Divided into four standards based on different appearances: D1602,D1802,D2002,D3002


Cool down and form the profile, the smaller the resistance is ,the better

Divided into four standards based on different widths: C1402,C1702,C2002,C3002.The quantity of calibrator parts are decided by profile, and extrusion speed.

Water tank

Cool down the profile further

Divided into three kinds: organic glass, stainless steel, pp board. They have wonderful tightness, brief frame, easily be processed.
