Process for producing injection molded products |
摘要 |
In producing an injection molded product by making a molten material flow from a cylinder through a plurality of gates in a die into a cavity and thereby filling the cavity with the molten material, a part of the flows of the molten material coming from a part of the gates is decreased or stopped before the flows of the molten material coming from a plurality of gate attain confluence in the cavity, and the flows of the molten material are made confluent by the flowing action of the flow(s) of the molten material coming from residual gate(s). According to the process of the present invention, the problem of mechanical properties in the injection molded products can be solved without adding any new apparatus to a general-purpose injection molding machine.
