Heating Elements for Plastic Molds – PET, PE, PP, ABS and Other Plastics

Looking for a We supply heaters for Depending on the mold and the area that needs to be heated, we can supply cartridge heaters, micro tubular heaters, coil heaters, tubular heaters, flexible heaters and other standard or custom-made heating elements.

What Type of Heater Is Used for a Plastic Mold?

There is no single heating element suitable for every mold.

Depending on the mold design and heating requirements, different types can be used:

• cartridge heaters for molds
• micro tubular heaters
• coil heaters
• hot runner heaters
• nozzle heaters
• tubular heaters
• flexible heaters
• flat heating elements
• heaters with built-in thermocouples
• custom-made heating elements

If you are not sure which heater you need, send us a photo of the mold or the old heating element together with its dimensions.

Cartridge Heaters for Plastic Molds

Cartridge heaters are one of the most common solutions for heating plastic molds.

They are installed directly into a hole in the mold, metal plate or block and transfer heat efficiently to the surrounding metal.

We offer many diameters, lengths and wattages for different mold applications. Special dimensions and custom-made cartridge heaters are also available.

Cartridge heaters can be used for:

• plastic injection molds
• PET molds
• PE and PP molds
• ABS molds
• metal blocks
• heated plates
• manifolds
• presses
• packaging machines
• other industrial equipment

Heating Elements for PET Molds and PET Preforms

We supply heating solutions for PET molds and PET preform production, including heaters for different areas of the injection molding system.

Applications include:

• PET preform molds
• PET injection systems
• injection nozzles
• hot runner systems
• manifolds
• heated blocks
• other temperature-controlled areas

Depending on the application, micro tubular, coil, cartridge or specially shaped heaters can be used.

Micro Tubular Heaters for Molds

Micro tubular heaters are commonly used when installation space is limited or when the heater needs to follow a specific shape.

They can be used for:

• plastic molds
• PET molds
• PET preforms
• hot runner systems
• injection nozzles
• manifolds
• heated channels
• local heating areas inside molds

Different sizes, shapes and configurations are available, including custom-made micro tubular heaters.

Hot Runner and Nozzle Heaters

Hot runner systems and injection nozzles require compact and reliable heating to maintain the correct plastic processing temperature.

Depending on the system, we can supply:

• micro tubular heaters
• coil heaters
• nozzle heaters
• cartridge heaters
• heaters with thermocouples
• temperature sensors

Heating Elements for PE, PP and ABS Molds

Our products are not limited to PET applications.

We can supply heaters for molds and plastic processing equipment working with:

PET • PE • HDPE • LDPE • PP • ABS • PVC • PA • PC

The correct heater depends not only on the plastic material but also on the mold design, available installation space, required temperature, wattage and heat distribution.

Do You Have a Burned-Out Mold Heater?

Have an old or burned-out heater and do not know the part number?

Send us a photo.

If possible, also provide:

• diameter
• length
• heater shape
• voltage (V)
• wattage (W)
• cable length
• connection type
• installation dimensions

With this information, we can help you identify a suitable replacement.

Cannot Find Your Size on Our Website?

Contact us.

Not every mold uses a standard heating element, and it is not possible to display every size and configuration online.

We can check your heater using a photo, dimensions, technical drawing or old sample.

For special applications, we can also manufacture custom heating elements according to the required dimensions, voltage, wattage and shape.

Mold Heating and Temperature Control

Heating the mold is only part of the process. The temperature also needs to be measured and controlled correctly.

For mold heating systems, we can also supply:

• thermocouples
• temperature sensors
• PT100 sensors
• temperature controllers
• PID controllers
• SSR solid state relays
• cables and connectors
• temperature control components

This allows you to find not only the heating element but also the components required to measure and control mold temperature.
