Ceramic Knuckle Heaters

We offer a wide range of high-quality Ceramic Knuckle Heaters designed for various industrial applications, including injection moulding, extrusion, blow moulding, rubber moulding, packaging, test equipment, laboratory equipment, and more.

Our commitment to quality ensures that our heaters consistently meet and exceed customer expectations in terms of performance and durability.

Ceramic Knuckle Heater Design & Construction

Our Ceramic Knuckle Heaters are engineered to meet the demanding requirements of modern industries, particularly where high temperatures and long service life are essential.

The core of the heater consists of a helically wound resistance coil, precisely stretched and threaded through specially designed refractory ceramic segments. These ceramic bricks form a flexible heating element, which is encased in a rolled metal outer shell and insulated with 4 mm thick ceramic fibre for maximum efficiency and thermal retention.

This advanced design delivers a robust, high-watt-density band heater capable of operating at elevated temperatures. Our standard models achieve temperatures between 400°C and 450°C, while specially engineered versions can reach up to 700°C to 750°C.

Additionally, we offer the option to integrate a built-in thermocouple upon request, providing accurate temperature monitoring and control.

Thanks to its flexibility and reliable performance, our knuckle metal ceramic heater is the preferred choice among leading European industries.

Advantages & Customization Options

Unlike conventional band heaters, Ceramic Knuckle Heaters operate primarily through radiant heating, offering superior efficiency and faster heat transfer. This unique characteristic makes them highly effective for applications requiring consistent and uniform heat distribution.

When installed on injection moulding machine barrels, these heaters can be equipped with a metal insulation jacket combined with 12.5 mm ceramic fibre insulation, providing energy savings of up to 25%. This not only reduces power consumption but also contributes to a cooler and safer working environment.

For extrusion applications, the heaters can be supplied with a mesh-style outer metal casing. This design creates air gaps between the ceramic segments, allowing for air cooling and enabling precise control of critical extrusion temperatures.

We also offer complete customized heating units for extrusion machinery, which can include:

• Outer protective cowls
• Integrated inlet and outlet air boxes
• High-output blowers or fans for enhanced airflow and thermal management
