Hot Runner Coil Heater for Injection Moulding

Product description

Hot Runner Coil Heater for Injection Moulding is constructed from nickel chrome resistance wire that is inserted within a chrome nickel steel tube that has been compressed for quick and effective heat transmission. The heaters are annealed to gain malleability and the ability to assume any form. There are also hot runner heaters with a thermocouple built in. Hot runner heaters with varying cross sections and an outside stainless steel and brass cover are used to make hot runner bushes.

FAQ

Installation Tips For Coil Heaters

The inside diameter of a coil heater is 0.020" smaller than the nominal diameter of a nozzle. This is done intentionally to secure a positive grip at all times. During installation, a coil heater should be screwed to its proper position. Pushing forcefully or slightly opening the coil to facilitate installation could permanently damage the heater.

During installation, only the straight cold section can be slightly bent. This should be done in a single attempt. The bending radius shouldn't be less than 0.5". It is always recommended to contact our factory when modifications of form are required.

The straight cold section can withstand temperatures of up to 1500°F. However, to protect the lead wires, the temperature of a section beyond the transition adapter should be maintained below 480°F.

Can we get some samples? Any charges?                                                              

Yes, free existing labels, you need to pay shipping cost.

Are you a factory or trading company?

We are the factory and have 10 production lines.

What's the Payment method?

T/T, 30% deposit before production, the balance before delivery. We suggest you transfer the full price at one time, because there will be a big bank fee if you pay twice.

What causes a heating element to burn out?

As a result of having to work harder, the damaged heating components eventually burn out. Draining your heater's tank every few months can help to minimize silt accumulation and increase the lifespan of the heating components.
