  • Injection molding machine
    Publication number: 20050220930
    Abstract: An injection molding machine includes an injection pot with an injection nozzle and a side casting port for feeding a material into the pot. The tip part of a plunger disposed in the pot is formed in such as shape that the tip part of the injection pot can be generally filled with the material after an injection is completed. A fitting part pressingly cuts off the material from the feeder by allowing a boundary part between the plunger body and its tip to be formed at a corresponding part between the injection pot body and its tip part.
