Your best choice | ELEKHEAT coil heater
Coil heaters provide efficient and versatile heating for various applications, including plastics processing, hot runner nozzles, and packaging machinery. Constructed with resistance wire encased in a durable sheath (often stainless steel), these compact heaters offer excellent heat transfer and can be formed into complex shapes. Key features include high watt densities and suitability for high-temperature environments. Selecting the right coil heater depends on wattage, temperature needs, and sheath material. Common search terms: flexible coil heater, nozzle heater, heating element, cartridge heater. Coil heaters are a reliable choice for precise temperature control.
What coil heaters do we have
Spring Coil Heaters
These heaters use a thermally conductive copper sleeve wrapped around the flow channel, ensuring rapid, uniform heat transfer.
- Pros: Excellent for demanding polymers like PA (nylon) and POM (acetal), which require tight temperature control.
- Cons: Higher manufacturing costs; regular maintenance to prevent oxidation.
- Best For: High-precision applications where heat consistency impacts material performance.
Copper Sleeve Coil Heaters
These heaters use a thermally conductive copper sleeve wrapped around the flow channel, ensuring rapid, uniform heat transfer.
- Pros: Excellent for demanding polymers like PA (nylon) and POM (acetal), which require tight temperature control.
- Cons: Higher manufacturing costs; regular maintenance to prevent oxidation.
- Best For: High-precision applications where heat consistency impacts material performance.
Embedded Coil Heaters
Embedded coils integrate heating elements directly into the runner walls, enabling fast response times and localized heating.
- Pros: Superior for fast-processing plastics like ABS and PP, minimizing cycle times.
- Cons: Complex installation and repairs; frequent inspections needed to avoid downtime.
- Best For: High-volume production prioritizing speed over ease of maintenance.
