Spring nozzle band heater

Data Sheet

Description

Spring nozzle band heater is designed for vertical and horizontal injection molding machines. With its compact size and excellent performance, the band heater plays an important role in the injection molding process. It has features of efficient heat transfer,the use of high-quality electric heating materials, to achieve rapid heating and stable heat transfer. Precise temperature control: precise size and structure design to ensure uniform temperature

Spring nozzzle band heater is also referred to as cable heaters. It is used in blow molding, plastics extrusion, injection molding, thermoforming, hot runner systems, and custom die applications. It can provide rapid heating and cooling due to its low mass construction, and tubular coil heater is sealed from contamination. The sheath of a coil heater can be made to be corrosion-resistant in very harsh environments.

It  has many applications but are mostly utilized as powerful heating cells inside hot runner nozzles in plastic injection molding. Spriral coil heater can accommodate "J" type or "K" type thermocouple sensors that could be placed internally at the tip or the middle of a heater.

Spring nozzle band heater is usually used for hot runner system.Hot Runner Coil Heater have advantages such as fast heating and cooling,even heating,high temperature resistance,anti-oxidation,good extensibility,good insulation and long usage life.

They are available in several sizes off the shelf, or customized to your order. Due to more durable construction and form fitting shape, our coiled nozzle heaters outlast the competition.

Various Watt Density options are available.Thermocouple is built in the hot runner coil heater. Coil heater feature maximum heat transfer due to more contact area.Standard sizes are available with various cross section.Hot runner coil heater is highly Non-corrosive and advanced thermal engineering.

Typical configurations

By specifically arranging a coiling pattern on the heater cable,heat distribution can be concentrated where it is needed .Useful to compensate for heat looses along the edges of the part being heated.

band heater normally do not require clamping straps as the inside diameter of the coil is wound undersize for a screw fit.At times because of differences in the expansion and contraction in materials a clamping strap maybe required to ensure circumferential clamping forces
