Description

Durable hot runner coil heater adopt imported high-purity Mgo, to ensure excellent heat conduction and electrical property . The wire is annealed for flexibility and can be sent in arcs or rounds for heating. It has high working temperature, fast heating speed, uniform heating accuracy, long service life, automatic area control, and high thermal conductivity. Coil heater is applicable to injection mold with high productivity and requirement.

Hot runner heaters with built in thermocouple are also available.

The durable hot runner coil heater is an industrial heating device, mainly used for metal heat treatment, fuel oil pretreatment and constant temperature heating of injection molds.

It works through methods such as electromagnetic induction or resistance wire heating, using an alternating magnetic field to generate eddy currents or direct heat inside the metal, which can reduce the viscosity of fuel oil and maintain a stable temperature in the plastic flow channel.

Hot runner heater is an important component of the hot runner system. Its heating accuracy and service life have a significant impact on the control of the injection molding process and the stability of the system's operation. After the heating tube is shrunk, the steel pipe becomes hard and needs to undergo better deformation. It must undergo high-temperature heat treatment to eliminate the mechanical tension of steel before they can be bent more easily.

Crafted with cutting-edge technology, durable hot runner coil heater ensure uniform temperature distribution, reducing energy consumption and enhancing productivity. Engineered for durability, spring coil heaters boast a longer lifespan, minimizing maintenance costs. Elevate your molding processes with reliable, high-performance heaters that deliver consistent results.

Resistances microtubule or Coiler type are small diameter resistance, but of high calorific value for electrical heating is needed in very small spaces and small. The heater wire is of the highest quality market with a thin outer layer and covered by a sheath of stainless steel, prepared for a process of compaction is achieved with longer life and become very hot. Resistance can take shape as required, thus conforming to the basic needs of each client. Solid surfaces can be heated well be straight (blade or folding), in a helical (pipes, injection nozzles) or other geometric shapes as needed.

Proper installation and regular maintenance are the foundation for ensuring the normal operation of the durable hot runner coil heater. Firstly, make sure the installation location is far away from flammable items and leave sufficient space for heat dissipation. Secondly, regularly clean the surface dust and dirt to avoid affecting the heat transfer efficiency; finally, check if the electrical connections are loose. If any abnormal conditions are found, contact a professional for repair in time.
