PLASTICS
Electric Heat Solutions for Plastics Manufacturing and Processing
Virtually every plastics manufacturing process relies on controlled heat. From melting and forming raw materials to sealing finished products, electric heating systems provide the precision, efficiency, and repeatability necessary for modern plastics production. Engineers rely on electric heat to maintain consistent process temperatures, improve product quality, reduce waste, and maximize production throughput.
Injection Molding
Injection molding machines require precise temperature control within barrels, nozzles, and molds to ensure proper material flow and part quality.
Common Heater Types: Band Heaters, Cartridge Heaters, and Strip Heaters
Plastic Extrusion
Extrusion processes depend on consistent heating of barrels and dies to maintain melt temperature and product uniformity.

Frequently Asked Questions
Hot runner systems use electric heaters to maintain molten plastic at controlled temperatures as it travels through the manifold and nozzles. Cartridge heaters, flexible heaters, and custom-engineered heating elements can be designed around the geometry and temperature requirements of the hot runner system.
Consistent temperature helps maintain proper material viscosity, flow, forming characteristics, and dimensional stability. Poor temperature control can contribute to defects, inconsistent parts, increased scrap, and reduced production efficiency.
Plastic extrusion equipment commonly uses band heaters around barrels and dies, along with cartridge heaters and flexible heaters for specific components. These heaters help maintain consistent melt temperatures as material moves through the extrusion process.
Band heaters are commonly used to heat injection molding barrels and nozzles, while cartridge and strip heaters can be used for molds, platens, manifolds, and other machine components. Precise temperature control helps maintain consistent resin flow and part quality.
Plastics manufacturing uses a wide range of electric heating technologies, including band heaters, cartridge heaters, strip heaters, flexible heaters, radiant heaters, process air heaters, and inline air heaters. The best heater depends on the process, operating temperature, required wattage, available space, and method of heat transfer.
