Electric heaters for injection molding machines, extruders, molds and hot runner systems

This category is designed for companies working with plastics and looking for industrial electric heaters, heating elements and temperature control components. The products are used on plastic injection molding machines, extruders, molds, nozzles, hot runner systems, PET preform lines, thermoforming equipment and other machinery where stable and controlled process temperature is essential.

If an injection molding machine no longer heats correctly, a barrel or nozzle heater has failed, a mold cannot reach its required temperature, or an extruder needs a replacement heater in a specific size, products can be selected by diameter, length, voltage, wattage and construction type.

Mica band heaters for barrels, nozzles and extruders

Mica band heaters are among the most widely used heating elements in plastics processing. They are fitted around cylindrical surfaces and are commonly used on injection molding machine barrels, extruders, nozzles and similar components requiring direct contact heating. The range includes multiple diameters and lengths, with cable, pin or terminal-box connections and different voltage and power options.

Ceramic band heaters for higher temperatures and continuous operation

Ceramic band heaters are suitable for more demanding thermal applications on extruders, injection molding machines and industrial processing equipment. They are often selected when higher operating temperatures, greater thermal efficiency or more intensive duty is required than a conventional mica band heater can provide.

Cartridge heaters for molds and metal blocks

Cartridge heaters are inserted directly into drilled holes in molds, plates and metal blocks. They are used in plastic molds, presses, injection systems, packaging equipment and other applications that require concentrated heat in a precise location. Correct selection depends on diameter, length, voltage, wattage and installation space.

Hot runner, nozzle and injection system heaters

Flexible and coiled microtubular heaters are available for nozzles and hot runner systems, including versions with integrated thermocouples. Typical applications include nozzle heating, hot runner channels, injection heads and PET preform systems. Depending on the machine, straight, coiled or formed heater configurations can be used.

Infrared heating for plastic thermoforming

Ceramic infrared heaters are used for thermoforming, sheet preheating and other processes where heat must be transferred by radiation without direct contact. The range also includes Elstein infrared heaters for industrial applications requiring stable and controllable radiant heat.

Temperature control, thermocouples and mold equipment

Reliable plastic processing requires both heating and accurate temperature control. The category therefore also covers thermocouples, sensors and temperature control equipment, including mold temperature control units and multi-zone systems. In hot runner and injection molding applications, the correct combination of heater, thermocouple and controller helps maintain stable temperature and reduce production downtime.

How to choose the correct heater for an injection molding machine or extruder

Do not select a replacement heater by wattage alone. Check the dimensions, inside diameter, length, supply voltage, power, connection type, cable or terminal position and any thermocouple hole. When replacing an existing heater, these values should be compared with the original component.
