MICA WELDBANDS - NOZZLE HEATERS

These elements are a metal or brass sheathed, mica insulated, nichrome wire wound and fully sealed (welded) construction. They come with many terminal options and design choices to suit every injection-moulding machine. Due to their welded nature, weldbands do not open up wide in their diameter so are generally most suitable for sliding on from the front.

MICA WELDBANDS - BARREL HEATERS (Refer Data Above)

Same internal construction as the nozzle weldband - these larger examples are handy for areas near the front of the barrel where blow back can be a problem as the heater is well sealed and not subjected to product contamination as readily. You do need to ensure that you can slide this heater on, as these can not be opened up to the barrel diameter unless a two-sectioned hinged element is specified.

TUBULAR BANDS - NOZZLE & BARREL HEATERS

Where high temperatures and high power is needed. These heaters are rugged and reliable - constructed with a stainless steel clamp band and a formed tubular element. They are slightly flexible in terms of diameter opening.

MICA FLEXBANDS - BARREL HEATERS

Designed to open up around the barrel, these elements are manufactured with a stainless steel clamp band and inner zinc plated steal element sheath.

CERAMIC FLEXBANDS - BARREL HEATERS

A flexible high temperature band heater also designed to open up around the barrel diameter. These high quality elements are constructed with a stainless steal clamp band and ceramic linking insulation. Note: The band length can only be increased by multiples of 15 mm.

CERAMIC WELDBANDS - BARREL HEATERS

These heaters are manufactured for their sealed protective nature and also their high temperature capabilities. They are however rigid as they are a fully welded construction with inner ceramic linking insulation. They are however very robust and a less expensive option than a cast in tubular element.

MINI TUBULAR

Metal sheathed magnesium oxide insulated mini tubulars are for use when space is resticted. Most commonly seen on nozzles and sprue bushes on plastic injection moulding machines, they can also be used for hot melt adhesive applicators, medical equipment and in heated rolling machines.

They can be supplied in straight length, coiled or formed. Successful coiling requires trades equipment and experience, we don't recomend DIY coiling. Mini tubulars are supplied with or without TYPE J thermocouple. The thermocouple is built in to a cold section at the tip of the tubular.
