stainless steel flat heater element mica band extruder heater

Description:

Many mold systems require heat as part of the manufacturing process. In the plastics industry, heaters are the key ingredient to maintaining temperature of the molten plastic. The plastic flows through the mold base, sprue nozzle, manifold, into a die head, or through an injection barrel. Without heat, the mold or machine is useless. Insulation is a key to heater life and performance.
Mica has a unique characteristic in that one can obtain very thin flakes with a consistent thickness. It conducts low amounts of heat, especially perpendicular to its strata. In addition, it is non-flammable, flame-retardant and does not emit fumes. From a heating perspective, mica is a solid option due to its resistance to erosion and arcing, and its dielectric strength. Additionally, mica is resistant to chemicals and water, and it has excellent compressive strength. It also holds up to bending stresses due to its high elasticity.
