Plastics & Forming

Vulcanic TEE offers a range of heating units to suit various processes within the plastics and thermoforming industries.
Listed below are just some of the ways we can assist you with your moulding and forming needs.

Nozzle Heaters

Nozzle Heaters for Injection Moulding

Nozzle heaters have been designed to last and reduce down time with high watt density capabilities to allow maximum temperature ratings and faster heat penetration into the nozzle.

Nozzle heaters are 6.35mm diameter stainless steel tubular roll formed, making them robust and eliminating the problems that normally occur with conventional mica nozzles.

Operating temperatures of up to 600°C are achieved with outstanding reliability and a long lasting life. With the multi-form construction, this heater can be opened and fitted easily without causing the damage that may normally occur with mica elements.


Low Profile nozzle heater is also available with all of the above capabilities as well as elements of 4mm diameter stainless steel tubular roll formed. They are used in applications where there is limited space around the nozzle. The LP type is available with the same dimensions and wattages as the TS and SN type nozzle heaters.

All Vulcanic TEE nozzle heaters come with 1 metre double glass insulated leads and 300mm tinned copper braid as standard. Many other options are available.

Thermalfold Cartridge

Thermalfold Cartridge Elements

Thermalfold high watt density cartridge heaters are of a unique design and are the latest in electric heating technology.

Thermalfold cartridge elements are manufactured 0.1mm to 0.5mm under-size to slide easily into the hole size specified. When energised, they heat up and spring open due to their folded construction. While in the heated condition, they are a snug fit and impossible to remove. On cooling, they contract back to their original diameter and become easy to remove again. Conventional cartridge heaters would normally fail under these conditions.

The maximum element temperature is 800°C. Work temperatures of up to 600°C are therefore achievable, depending on the application.

Thermalfold cartridge heaters range in size from 6mm to 25mm diameter, with various lengths available on request.

Thermalfold heaters are specially manufactured to suit your requirements. When ordering, please specify the following dimensions (as per diagram to right):

  • A – Heating Length
  • B – Overall length of Thermalfold
  • C – Length of terminating leads with or without metal flexible conduit
  • D – Hole size in which Thermalfold is to fit
  • E – Voltage and wattage
Band Heaters

Band Heaters

Band Heaters have been designed to last and reduce down time. Band Heaters have high watt density capabilities which allow maximum temperature ratings and faster heat penetration into the barrel.

Vulcanic TEE Band Heaters are manufactured in 6.35mm and 7.9mm diameter stainless steel tubular roll formed construction, making them robust and eliminating the problems that normally occur with conventional mica band heaters.

Operating temperatures of up to 600°C are achieved with outstanding reliability and a long lasting life. With the multi-form design, these heaters can be opened and fitted easily without causing damage to them that may normally occur with mica elements. A uniform and greater heating area around the barrel is made possible due to this construction, whereas a mica band heater for applications with thermocouple holes and cut outs may, in many cases, heat only half of the area that the element has been designed for.

Vulcanic TEE Band Heaters come standard with 2 metre double glass insulated leads fitted with either tinned copper braiding or stainless steel flexible conduit for protection against mechanical damage. If desired, a plugall assembly or terminal enclosure can also be fitted. The two designs available are BH type and DBH type.

Thermocouples

Thermocouples

Various styles of thermocouples for the smelting, heat treatment and furnace manufacturing industries are available through Thermal Electric. Styles include straight or angled, with single, duplex or triplex elements and numerous cold leg materials and terminal heads. Protective sheath materials include Sialon, Silicon Carbide, Laminated Ceramic, Plumbago, Chrome Iron, Cast Iron, Inconel 600 and 601, 253MA, 316-310 S.S., Pythagoras GR61, Alsint AL23, Mulite and Sillimantin.

A full range of Lance dip probes are available, incorporating the MARSHALL Type K and N replaceable 8 inch long life chrome iron tips.

Applications: Specifically designed for non-ferrous metals, aluminium, copper, brass, bronze or salt baths at temperatures to 1300°C.

Various styles of thermocouples and sensors are manufactured for the petrochemical industries. The sensors shown are a small example of what is available. Assemblies available with single and duplex elements in numerous OD sizes, insulated or bonded thermocouple junctions, element sheath materials, spring loaded for terminal blocks and barrel unions.
Also available are thermowells – fabricated or machined bar stock; screwed or flanged; in various metals; specialty coatings; weld on pads; ceramic sheaths; barrel unions; nipples; a large range of mounting hardware; terminal head materials – alloy, cast iron, SS, plastic, bakelite and SAA approved explosion proof Ex”d”.

Ceramic Heaters

Ceramic Heaters

Vulcanic TEE ceramic infrared heaters provide a reliable, economical and highly effective source of infrared heat. Because of their versatility, they can be easily adapted to solve many manufacturing problems.

In the plastics industry, banks of ceramic heaters are used in thermoforming products.
The specially designed yellow ceramic heaters are very useful in this process, as they will turn white when heated. If one ceramic heater has failed it will remain yellow, making it much easier to identify which heater is not working and needs to be replaced.
