Mica Band Heater for Extruders and Plastic Injection Machine

Product Description
Strip heater is the most suitable cylinder heater to fix up in the outside of plastic extrude and plastic injection molding. And it is used to thermal conduction and heat.
This kind of heaters chooses mica as the basic material. Because mica withstands high voltage spikes, high heat conductivity, resists moisture, is insert to most chemicals and is flexible enough to confirm to the curve of the cylinder without cracking. Its basic structure is twisting the nicke-chrome wire enenly on the mica slice, wrapping up and down by the mica slice to insulate, packing wioth the copper panel or the stainless steel outside, and then curving it into cylinder.
The heater which has one partition is called single slice form. If it has two partitions it is called double slice form. The standard products all use metal strips to tighten. The carry ons which connect to the power all use the screw type as the standard. Its make-to-order shape can be the line-out type. But for the structure it can not be durable.
Although strip heater has a smooth surface and flexibility, it still needs choosing exact size to ensure the heated material has high efficiency thermal conduction , and enlarge the life span.
Intalled in the extrusion cylinder, the inner parts of the heater should be in close contact with mica. If there is space between them,  the outward surface temperature will exceed the allowance because of the bad thermal conduction. And the service life will be influenced.
