Choosing Cartridge Heaters for Molds, Dies, Packaging & Industrial Equipment

Cartridge heaters for industrial equipment are widely used in molds, dies, packaging machines, sealing equipment, and other industrial machinery. However, different applications may require different heater sizes, wattage, watt density, and lead configurations.

Cartridge Heaters for Industrial Equipment

Cartridge heaters provide localized heating and are commonly installed in drilled holes, heating blocks, molds, and metal plates. Typical applications include:

• Injection molding molds and dies
• Packaging and sealing machines
• Heating blocks and metal plates
• Plastic processing equipment
• Industrial machinery and automation equipment

The right cartridge heater depends not only on temperature and power requirements, but also on the installation environment and mechanical conditions of the equipment.

Case Study: 8 mm Cartridge Heater for a Packaging Machine

A customer from Hungary has been using our cartridge heaters for a packaging machine for more than four years. The application required an 8 mm cartridge heater operating at approximately 140°C.

Initially, the machine used a standard cartridge heater with an external lead wire. During continuous operation, vibration and repeated heating caused the lead wire connection to break repeatedly.

The Problem Was the Lead Configuration

The heater itself was working, but the external lead configuration was not well matched to the mechanical conditions of the packaging machine. Continuous vibration combined with long-term thermal cycling placed additional stress on the lead connection.

The Solution: Internal Lead Configuration

We changed the heater from the original external lead design to an internal lead configuration, with the lead wire routed from inside the heater structure.

This configuration reduced mechanical stress around the lead connection and provided a more suitable solution for the customer’s vibrating packaging equipment.

For us, supplying a cartridge heater is not only about matching diameter, voltage, and wattage. We also listen to what happens after installation and help customers find a better solution when the original configuration does not match the application.

After more than four years of cooperation, this Hungarian customer has become a long-term business partner of EaseWise. We are always happy to help customers select the right cartridge heater configuration for their equipment.
