The path of the nozzle and screw head should be designed so that there is no dead angle, so that the material can be injected without being damaged by heat. Accurate temperature control of the heating system of the screw barrel and nozzle is the focus. Make sure that the nozzle is heated evenly throughout its length. Beware of local overheating of the melt on the path and possible cold. The molten TPU is non-corrosive and non-abrasive. For this reason, the screw does not require any special alloy steel or reinforced coating.
