Band Heater (SS, Brass & Ceramic) for Industrial Barrel Heating

Band Heater for Industrial Barrel Heating — Mica (SS) Type

Mica band heaters deliver rapid heat transfer, stable temperature control, and long service life. Using high-grade mica insulation and stainless steel sheathing, this heater is the go-to choice for plastic extrusion, injection molding, and general industrial barrel heating.

Typical Applications

• Plastic extrusion machine barrel heating
• Injection molding machine plasticizing zone heating
• Blow film machine die head temperature control
• Pelletizing machine barrel heating and preheating
• Extrusion die head heating for polymer and engineering plastics
• Chemical reactor vessel / drum heating
• Food processing drum and pipe heating
• Pharmaceutical processing barrel heating
• Heating for small tanks, pipes, and industrial cylinders

Key Features

• Fast heating speed and rapid thermal response
• Excellent dielectric strength using mica insulation sheet
• Compact structure suitable for small and medium diameter barrels
• Wide power range, customizable watt density
• Stable heating performance and long lifetime
• Multiple lead wire options: ceramic terminal, stainless braid, fiberglass lead
• Easy to install and low-maintenance on injection molding machines

Band Heater for Industrial Barrel Heating — Brass Band Heater

Brass band heaters are engineered for applications where superior thermal conductivity and corrosion resistance are critical. The brass outer casing transfers heat more efficiently than stainless steel, making it the preferred choice for high-speed extrusion lines, chemical processing, and moisture-prone environments.

Why Choose Brass

• Higher Thermal Conductivity — Brass transfers heat faster than SS, reducing warm-up time and improving energy efficiency.
• Corrosion Resistance — Withstands exposure to moisture, chemicals, and high-temperature oxidation.
• Uniform Temperature Distribution — Ensures consistent melt quality in extrusion processes.
• Durability — Robust construction for long-term use in demanding industrial environments.

Typical Applications

• Plastic and rubber extrusion systems
• Chemical processing barrel heating
• Food extrusion and packaging lines
• High-temperature extrusion requiring fast heat recovery
• Moisture-prone industrial environments

Band Heater for Industrial Barrel Heating — Ceramic Band Heater

Ceramic band heaters are the premium choice for high-temperature industrial heating. Using ceramic insulation instead of mica, these heaters deliver higher temperature capability, better energy efficiency, and longer service life. With an optional insulation jacket, they can reduce energy costs by 20–30%.

Why Choose Ceramic

• Higher Temperature Capability — Up to 760°C, far exceeding mica band heaters.
• Energy Efficient — Optional insulation jacket reduces heat loss by 20–30%.
• Longer Service Life — Ceramic insulation resists degradation better than mica at high temperatures.
• Lower Surface Temperature — Improved safety and reduced ambient heat in the workshop.

Typical Applications

• Plastic injection molding machines (high-temp barrel zones)
• Extrusion machines and die heads
• Blow molding machines
• Plastic recycling and pelletizing lines
• Rubber machinery and tire production
• 24/7 heavy-duty production environments
