PE1800 Heat-insulating In-mold Co-extrusion Die Head

Performance Characteristics: Two raw materials need to be fed separately. It is equipped with an efficient heat insulation structure and heat insulation materials. The junction of the two raw materials is close to the die lip, minimizing heat transfer interference. Secondly, due to the large temperature difference, the deformation of the mold steel due to thermal expansion and contraction must be considered. Since the relative positions of the two flow channels of this type of die are very close and the contact area of the die body is small, the heat insulation range is generally within 80°C.
