My Belt Heaters With Mineral Insulation

They usually contain terminal kits that facilitate installation. Belt heaters are used for injection molding drums and nozzles, extrusion and molding presses, pipe heating, heat treatment and autoclaves, food industry and other applications. Belt heaters are efficient and economical solutions for the heating needs of many Industrial Band Heater Manufacturer applications. An expanding mica belt heater is an internally mounted belt heater that is especially useful when it only provides space for an item in a pipe or heating tool. Mica belt heaters are widely used for plastic injection molding and contact heating in machines, nozzles, tools, piping systems, and blow molds.

Notched edges fold to secure the ends, and a protective lining ensures the placement of the tiles. This combined set of ceramic belt heating provides a flexible heating system that generates efficient transmission of conduction and radiant heat. Like many maintenance products used in the plastic injection molding industry, belt heaters are often not in the foreground until a problem occurs.

Belt heaters are thin and therefore ideal for effective heat transfer. Coated belt heaters consist of a tubular heating element formed according to the diameter of the part to be heated and held in place by an external clamping tape that acts as a reflector. These belt heaters are designed for a maximum operating temperature of 350°C and can be manufactured for easy installation and for large diameters in one or more parts. Mica tape heaters consist of a nickel-chromium resistance wire wrapped around a layer of mica, which is then placed between two additional mica blades. An outer jacket made of corrosion-resistant steel encloses and protects the wire and mica sheets. AlumaFlex belt heaters are perhaps our most robust industrial belt heater with a tubular heating element embedded in an aluminum channel.

For heaters with multiple straps, alternately tighten each belt until no additional tightening can be performed. Make sure that all surfaces of the barrel are clean and free of contaminants that can enter the heater through wiring, etc. to avoid electrical short circuits and/or heating failures. If thermocouples are part of the heater, make sure they are free of contaminants and have a good response to temperature changes to avoid overheating.

UL® component detection is available for applications up to 900°F for jacket temperature. Make sure that the voltage input to the heating tape does not exceed the permissible nominal voltage for the heating. If the heater contains screw terminals, remove the TOP nut and flat washers from the feed screw terminals.

We make sure the inner surface is smooth and consistent in shape to avoid hot spots or poor fit. Belt heaters are made to order as they vary in size and performance. The area from which heaters are used is often exposed to liquids, and therefore the wires can be completed with a protective cable. Cables can be installed from the front or edge of the heater to facilitate the installation of heaters in areas where space is limited. Cables can also be installed from a terminal housing and a braided metal jacket for additional protection if required.
