Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of band heater of injection molding machine in China, also supports custom service. Welcome to wholesale high quality band heater of injection molding machine at competitive price from our factory.
At present, most of the injection molding machines on the market use band heaters as the main heating elements in the heating system. The ceramic band heaters are based on the current resistance heating effect to generate heat, that is, when the current passes through the conductor, the resistance of the conductor hinders the current, and the current must overcome the conductor's resistance does work to convert electrical energy into heat and transfer it through contact conduction. Therefore, the inner wall of the heating ring and the outer wall of the barrel must be in reliable and close contact to transfer the heat to the barrel.
The band heaters has the advantages of low price, simple structure, and low failure rate due to the simple structure. And based on the insulation material, there are mainly Mica material and ceramic material. We call them as Mica band heater and ceramic band heater, both types of band heaters are very popular used as the heating elements on the injection molding machine.
1-Mica Band heaters：
Mica band heaters are made of nickel chrome resistance ribbon precisely wound on specially selected mica sheet. It is then insulated and covered by metal sheathing and rolled to the required shape.Band heaters are designed for cylindrical shaped solids. It grips tightly to cylindrical surfaces to supply uniform heat transfer, critical to the heater life. Ideal for every type of plastic processing equipment.

2-Ceramic Band Heaters：
Ceramic band heaters are made of helically wound nickel chrome resistance coil precisely stretched and strung through steatite ceramic cores forming a flexible heating mat. It is then placed in flexible stainless steel housing with ceramic fibre insulation. These heaters are very flexible and can be fitted easily. Durable, ceramic band heaters provide excellent energy efficiency with their built-in ceramic fiber jackets.
