Cold-feed Extruder

Product Detail

Shenghualong Rubber Machinery is one of the leading cold-feed extruder manufacturers and suppliers in China, we are able to offer you cheap cold-feed extruder made in China and welcome to check the price with us.

usage :

it is mainly used for continuous extrusion and forming of rubber sealing strip, with frame strip, rubber sheet, tape, tubes and other shape of dense or foaming rubber frofiles for auto, construction, water conservancy, roads and bridges, electric , machinery and other industries.

features:

1. The barrel is adopted of water jacket structure, is composed of several temperature zones.

2. The screws and barrels are made of high quality alloy steel with nitrogen hardening which makes it more wear-resistant and more corrosion protection.

3. The temperature each zone may be automatically probed and controlled by mould temperature controller with good sensitivity, and can be adjusted according to requirement of process.

4. The extruder is driven by a change frequency motor , which achieve continuous and smooth speed regulation.

5. the extruder is equipped with vacuum pump and vented type screw to vent the air and water of rubber materials during mixing and plasicate
