Machinery-Standard vertical injection molding machine, electric bicycle handle vertical injection molding machine, bicycle handle vertical injection molding machine, there are three feeding methods: front feeding, rear feeding and fixed feeding. Generally, the appropriate feeding method is selected according to the nozzle and material conditions. 1. Pre-feeding: After each injection is completed and the plasticization reaches the pre-plasticization requirements, the injection seat will move backwards until the next working cycle and then move forward so that the nozzle is in contact with the mold for injection. This method is used where the nozzle temperature is difficult to control, the back pressure is high, and the backflow is prevented. 2. Post-feeding: After the injection is completed, the injection seat will move back, and then pre-mold. When the next working cycle starts, the injection seat will move forward for injection. This method is used to control the temperature of the nozzle and process clean plastics. 3. Fixed feeding: During the entire injection molding process, the nozzle and the mold have been kept in contact. This method is suitable for situations where the nozzle temperature is easy to control and the plastic molding temperature range is wide. The standard vertical injection molding machine, electric bicycle handle vertical injection molding machine, and bicycle handle vertical injection molding machine produced by the machinery company are all designed, manufactured and assembled in accordance with the specifications of the European Plastic and Rubber Machinery Manufacturers Association. It has the characteristics of high rigidity, strong clamping force, high injection pressure, precision and durability.
