Hot runner coil heaters from Shenglong Heaters are industrial heaters with small diameters, but with a great heating power. It is particularly suitable for use in hot runners systems for plastic industries and many other thermal processes, where ever high electrical heating performance is required in the tightest of spaces.
Hot runner coil heaters can be wound or bent according to the customers wish in nearly every geometrical form; therefore it offers a great adaptation on solid surfaces which require to be heated.
