Cast-In Extrusion Die Heater

The cast aluminum extrusion mold heating element is a high-performance electric heating component specially designed for plastic extrusion machinery, injection molding machinery, and rubber processing equipment. This heating element uses high-quality alloy electric heating wires as the heating body and is precisely processed and cast into an aluminum alloy or bronze housing to form an integrated heating structure.
The cast aluminum extrusion mold heating element has excellent thermal conductivity, uniform heating effect, and good mechanical strength. It not only ensures uniform heating of plastic raw materials during the extrusion process but also effectively extends the equipment lifespan and improves production efficiency.
This product supports customization according to customer requirements. It offers various voltage levels, power capacities, sizes, structural forms and installation methods to meet the needs of diverse complex working conditions.

Product Advantages

Uniform heating: The overall casting process is used to avoid local overheating or excessive temperature differences.

Excellent thermal conductivity: Aluminum alloy or bronze materials possess extremely good thermal conductivity, resulting in high thermal efficiency.

Sturdy structure: Cast as a whole, with high mechanical strength and excellent durability.

Long service life: Utilizing imported high-temperature electric heating elements and high-quality insulating materials, it is durable and reliable.

Customization flexibility: Design can be tailored according to the size, voltage, power and shape of the customer's equipment.

Easy to install and maintain: Fixed by bolts or flanges, with convenient disassembly and assembly.

Customization capability

We can offer the following customized services based on the actual working conditions of our customers:

Size customization: Circular, semi-circular, square, plate-like and other structures, with diameters ranging from 50mm to over 1000mm.

Material selection: Aluminum alloy (lightweight, fast heat conduction), Bronze (better corrosion resistance).

Power/ Voltage: 110V / 220V / 380V or other voltages. Power is designed according to the requirements of the mold.

Temperature control method: It can be equipped with a built-in thermocouple (K/J type) or a temperature control probe, which, together with the control system, enables precise temperature control.

Surface treatment: Anodizing and applying a wear-resistant coating to enhance corrosion resistance.

Application Areas
