mica heaters, band heaters, immersion heaters, extrusion heaters, injection moulding heaters

Mica heaters form the core of most general machine heating applications as they are inexpensive and infinitely variable in shape and concept.

LPC engineers pride themselves on their ability to provide solutions for the most complex shaped dies and heating applications. Variations manufactured by LPC include round, half round, segment, flat, angle, box shape, conical, "U" shape, disc and ring shape, in sizes from ¾" (20mm) diameter and widths up to 30" (760mm), incorporating a variety of holes, cutouts, fittings and terminations to accomodate your applications and control systems.
Clamping:
Clamping can be either roller bolt, edge bracket or "quick release" shackle as required. Mica heaters, especially flat, angle and box shapes, should be clamped using backing plates of at least one eighth of an inch (4mm) to avoid premature failure
Mica heaters are best used in applications where there is no possibility of spillage as they are not of sealed construction.

Construction:
Mica heaters are constructed with four plates of phlogopite mica wound and encased in coated mild or stainless steel for optimum flexibility, heat transfer and strength. Element resistors are wound from top grade 80/20 nickel chrome and are carefully spaced to provide even heat. The heaters are precision rolled and formed to fit your application.
