1, Shorten the production cycle. 2, Reduce injection molding material waste, and product quality improved and become more stable. 3. Valve gate hot runner injection at the low-pressure,thus only small product distortion due to contraction. 4, Valve gate hot runner make it possible to inject at low temperature. 5, Reduce the thermal shear phenomenon near injection gate. 6, Valve gate hot runner make it possible to control the plastic injection volume of each injection gate. 7, Due to reduction of the pressure loss , it is suitable for a variety of plastic products. Second, due to the above characteristics, valve gate hot runner is suitable for the following products: 1, Plastic injection molding products made with the fast crystallization material; 2, Plastic injection molding products with long closing mold time due to thick wall; 3, Air-assisted injection molded parts; 4, Thin wall injection molded parts. Wooden cases or cartons.
