With 20 years experience, Hongtai Alloy is your trusted source for quality 110v two-piece stainless steel mica band heater as one of the leading suppliers of various heaters in China. Providing you with the most competitive price, we welcome you to buy the heater from our factory.
Product Overview
Available in inner diameters ranging from 50mm to 600mm, this two-piece stainless steel mica band heater is engineered primarily for plastic injection molding barrels, extruder cylinders, blow molding dies, and other cylindrical surface heating applications. The split mica band heater is constructed with a corrosion-resistant SUS304 / SUS430 stainless steel outer sheath, laminated with high-grade muscovite or phlogopite mica insulation plates and a precision-wound NiCr8020 resistance ribbon core. Its two-piece split-ring clamping design allows technicians to install or replace the heater directly around obstructed machine barrels without disassembling feed throats or die heads. Key operational benefits include low-profile construction, direct conductive heat transfer, uniform barrel temperature profiling, and mechanical clamping stability. Each half-band can be wired independently for 110V operation or connected in series for 220V systems, equipped with stainless steel clamping flanges, socket head cap screws, and customizable terminal terminations.

Industrial Case Studies
Case 1: Mid-Barrel Heater Replacement on Injection Molding Machinery
- Operating Condition: Replacing a failed heating element in the center zone of a 150mm injection molding barrel obstructed by feed throats, hydraulic lines, and fixed die heads.
- Engineering Implementation: Installed a 110V two-piece stainless steel mica band heater configured as two independent half-rings wired in series for a 220V power supply, featuring precision-punched thermocouple cutouts and stainless steel braided lead wires.
- Performance Result: Enabled direct lateral mounting onto the barrel without disassembling the nozzle assembly or front platen. Maintained uniform conductive heat transfer at 280°C across continuous multi-shift molding cycles.
Case 2: Dual-Voltage Barrel Heating on Export Plastic Extruders
- Operating Condition: Machinery manufacturer building plastic extruders for North American and Latin American facilities requiring 110V / 220V dual-voltage wiring flexibility and low-profile clearance under safety shrouds.
- Engineering Implementation: Deployed split-ring SUS304 mica band heaters (4.0mm wall thickness) with threaded post terminals and ceramic insulating caps, clamped via high-tensile Allen bolts and barrel nuts.
- Performance Result: Allowed field technicians to wire the halves in parallel for 110V operation or in series for 220V systems. The low-profile 3.5 W/cm² design fit cleanly beneath tight barrel insulation covers while preventing localized hot spots and premature dielectric breakdown.
