L Shaped Square Cast In Barrel Heaters For Plastics Processing
Description
The “L” shape cast-in heater design is typically used on square and rectangular extruder barrels,
Which utilize a twin screw design. In most cases,the high operating temperatures in these applications require these cast-in heaters to be constructed of a bronze alloy, however aluminum alloys are used for applications which do not require the higher watt densities. While the most common design for “L” shaped cast-in heaters consists of heat only, they can be manufactured with cast-in cooling tubes. Typical mounting options include manufacturing the cast with 45°mounting flange which allows the cast-in heaters to be bolted and drawn together on the barrel or the cast-in heater can be supplied with mounting holes machined into the casting to mount directly to the barrel. The most common electrical termination for the “L” shape designs is a junction box mounted on to a vented tower that extends from the body of the casting . The box has a gasket for moisture resistance and can also be supplied with explosion proof specifications. The junction box can also be cast directly onto the heater. High temperature leadwire with a heavy-duty bronze braid is also available upon request.
