Industrial High Efficiency Heating & Cooling System Design for Twin-Screw Extruders

Introduction of Heating & Cooling System Design for Twin-Screw Extruders

Heating & Cooling System Design for Twin-Screw Extruders are mainly suitable for fully extruded parts. They are combined of several heaters with cooling system. According to the applications, the main parts can be combined into one system, as the extrusion cylinder is completely covered, the temperature will be uniform, and at the same time it has a bigger radiation area. It can also eliminate the frictional heat caused by extrusion. As the ceramic beads have good conductivity, using it as insulator, the heater could heat up and cool down faster and more efficiently. This heater is recommended for customers with high cost performance requirements.

Applications of Heating & Cooling System Design for Twin-Screw Extruders

(Especially for Products which are sensitive to temperature.)

Plastic Extrusion

Injection Molding

Blow-Molding

Pressure Molding

Structural Foam

Food Industry

Container Pipe and Tank Heating

Packaging

Chemical, Oil & Gas Industries

Types of Heating & Cooling System Design for Twin-Screw Extruders

Air cooled ceramic heater

Air cooled mica heater

Air cooled aluminum heater

Air cooled ceramic heater with ceramic fins

Air cooled ceramic heater with copper fins

Air cooled ceramic heater with nickel plated copper fins

Features of Heating & Cooling System Design for Twin-Screw Extruders

These Fins are available in width of 45mm, 60mm & 75mm.

Aluminium Fins take 25% & Copper fins takes 35% less time to reach set temperature of 350° C than standard Fins.

Aluminium Fins take 30% & Copper fins takes 35% less time for cooling from 350° C to 100° C than standard Fins.

If working temperature requirement is around 300° to 350° C, it is recommended to use Aluminium Fins as it is cost wise economical.

Aluminium & Copper cooling fins have a maximum operating temperature of 450° C.

These fins can also be used in mounting between heaters as cooling fins.
