Ceramic Band Heaters for Twin-Screw Extruders
These ceramic band heaters are professional heating components specially designed for co-rotating parallel twin-screw extruders, widely used in plastic modification, WPC compounding, PE pipe extrusion, EVA/POE film production, and lithium battery diaphragm extrusion. Adopting high-purity ceramic heating elements and 304 stainless steel outer casings, they feature rapid heating, uniform temperature distribution, and excellent heat insulation performance—effectively reducing heat loss and improving energy efficiency for extruder production lines.
With a high-temperature resistance design (up to 600℃) and stable heating performance, these ceramic band heaters ensure precise temperature control (±1℃) of the extruder barrel, which is critical for uniform plasticizing of materials such as PP/PE, EVA/POE, WPC composites, and ultra-pure resins. Their compact structure, strong vibration resistance, and easy installation make them suitable for long-term continuous operation of twin-screw extruders, reducing maintenance frequency and downtime.

Frequently Asked Questions (FAQ)
Q: Why choose ceramic band heaters for twin-screw extruders?
A: Compared with ordinary heating coils, ceramic heaters have better heat insulation, faster heating speed, and higher temperature control precision (±1℃), which can avoid uneven material plasticizing caused by temperature fluctuations—critical for high-quality extrusion production.
Q: What is the advantage of the clamp-on design?
A: The clamp-on installation is simple and quick, no need for complicated disassembly of the extruder barrel, which greatly saves time for heater replacement and maintenance, reducing production downtime.
Q: Can these heaters be customized to fit my extruder barrel?
A: Yes. We can customize the inner diameter, length, power, and voltage of the heater according to your extruder barrel size, model, and heating requirements, ensuring perfect fitting and optimal heating effect.
With high-purity ceramic heating elements, precision temperature control, and easy installation, these ceramic band heaters are the ideal heating solution for co-rotating parallel twin-screw extruders. They solve the core difficulty points of uneven heating, high energy consumption, and difficult maintenance of traditional heaters, ensuring stable and efficient operation of extrusion lines. Suitable for various high-demand extrusion scenarios, they are a cost-effective and reliable matching component for plastic processing enterprises.
