Overview of Cast Aluminum Heaters

Posted on by

Cast aluminum heaters or cast-in heaters are an essential component for all plastics extrusion machinery. Extruder barrel & die heaters are made of aluminum or bronze. Stringent machining tolerances on the inside working surface and high quality heating element construction guarantee high performance.

 

Cast aluminum heaters offer a high quality and efficient method of heating and controlling Extruders, Compression Molding Platens, Heat Sealers, and Vacuum Forming Platens.

 

The heat cool capabilities of cast-in heaters provide high accuracy temperature control of +/- 2º.

 

These precision cast aluminum heaters are available in various sizes and watt densities ranging from 10 t0 60 watts per square inch.

 

They are pressure casted insuring a dense porosity free casting that can been supplied with either cooling fins or seamless stainless steel cooling tubes that guarantee longer life.

 

They can be casted into any shape and size needed, thus fully covering the part to be heated and virtually becoming the part itself. Most Cast In heat cool bands are made to customer specifications, but standard sizes are available out of stock.

 

Cast aluminum heaters are contamination and corrosion resistant and can with stand high temperature and pressures in harsh environments with years of trouble free service.
