Screw heater for multifilament yarn spinning machine

1. Product Description

Screw heater for multifilament yarn spinning machine

The cast in heaters are composed of one or more electrical heating elements embedded in an aluminum alloy, brass, bronze, copper-nickel or iron type material with excellent thermal conductivity.

The gravity casting provides excellent homogeneity of the casting material and therefore allows excellent thermal diffusion. The regularity of the surface temperature is ensured by a suitable forming. The cast heating elements can be used to surface temperatures up to 750 ° C.

Air-cooled cast-in heaters operate with less maintenance and longer life than liquid-cooled cast-in heaters. 

Cast heaters have usually a longer heater life than other heaters, but the investment costs are typically higher. For testing purposes, a cost efficient sand mold can be used to produce the first couple heaters.
