Barrel Heaters are efficient industrial heating devices designed to provide consistent and uniform heat around cylindrical surfaces such as barrels, drums, and extruder machines. Commonly used in plastic processing, injection molding, and extrusion industries, these heaters help maintain precise temperature control for melting, molding, and material flow. Constructed with high-quality resistance wires insulated by mica or ceramic and enclosed in a durable stainless-steel or aluminum sheath, they ensure excellent heat transfer and long operational life.
