Cartridge heaters for industrial applications

Cartridge heaters are used for precise local heating in equipment where tight thermal contact and temperature stability are critical. They are installed in accurately machined holes and provide efficient heat transfer under high load conditions.

This type of heater is used in injection molding machines, molds, plastic casting, packaging, and welding equipment. The operating temperature reaches up to 750 °C, and the design is adapted for cyclic operation modes.

Range of Cartridge Heaters

Standard Cartridge Heaters

Basic models are available with power ratings from 100 to 1000 W and a voltage of 230 V. They feature compact dimensions, a stainless steel sheath, and a standard design for typical mounting locations. Such cartridge heaters are suitable for a wide range of tasks, including heating metal assemblies, plates, or molds.

Spiral Cartridge Heaters with Thermocouple

This category also includes spiral cartridge heaters with a built-in type J thermocouple. These are GME and GC-heat models with a heating zone length from 160 to 1300 mm and power from 195 W to 1000 W.

GC-heat products (for example, 195W/230V, 230W/230V, 690W/230V) are designed for high-precision tasks with long-term thermostable loads. They provide uniform heat distribution along the entire length of the heating zone, are resistant to overheating, and have extended service characteristics.

GME heaters are an optimal solution for applications with medium operational requirements, where the balance between price and functionality is important. Models are available with heating zones from 205 to 1300 mm and power up to 1000 W.

Design Features

• hermetically sealed sheath
• leads with strain relief
• resistance to thermal shock
• precise alignment of the heating zone with the working surface
• integrated thermocouples (type J) for real-time temperature control

These features ensure long-term, trouble-free operation in critical conditions — in areas with intensive cyclic loads or in equipment with strict temperature tolerances.

Custom Cartridge Heater Manufacturing

For non-standard applications, custom cartridge heater manufacturing is available. Adaptation is possible for the following parameters:

• non-standard length or diameter
• non-standard power (from 175 W to 1200 W)
• limited or zoned heating area
• modified connection (angled leads, silicone sealing, metal fittings)
• integration of thermocouple J or K

Such solutions are used in specialized units where standard products do not provide the required thermal profile or structural compatibility. All products undergo technical approval with the customer’s engineering team.

Applications of Cartridge Heaters

• injection molding (aluminum, plastic)
• rubber production
• heat-sealing packaging equipment
• molds in metalworking
• laboratory thermostatic equipment
• thermal stabilization of components in automated lines
