What are the classifications of band heater?

Band heater can be divided into stainless steel band heater and casting band heater, which are subdivided into stainless steel mica band heater, stainless steel ceramic band heater, cast aluminum band heater, cast copper band heater, and cast plate band heater/plates.

1. The stainless steel ceramic band heater is not made by the general mica wire bending method, but by the ceramic wire threading method, so the power of the product is 0.5 to 1.5 times higher than the ordinary one.

The heating element is made of imported round wire ceramics, which is bent into a spring shape and inserted into a ceramic strip. The outer cover is made of stainless steel, and the middle is made of high-temperature heat insulation cotton to prevent temperature leakage. It is currently the most suitable electrical system for extruders, injection molding machines, and film blowing machines. Heat the product.

2. Cast aluminum band heater can be divided into die casting and press casting. In the occasions with more specifications and sizes, the casting process is generally used. High-purity aluminum blocks are used in casting production, which are changed from solid to liquid in a high-temperature furnace, and then injected into a mold that has a heating tube installed, after cooling and forming, and then finishing.

Basically, the cast aluminum band heater  is divided into half of the circle, made into two semicircles, and then fixed and installed by fixing bolts.
