The principle of injection molding

  1. Add the granular or powdered plastic material to the drying hopper of the injection machine to dry and dry.
  2. After the drying of the plastic raw material under the action of gravity from the dry hopper into the plastic injection moulding machine
  3. The plastic raw material is liquid when heated in the heat of the injection molding machine.
  4. The injection screw in the injection molding machine is used to inject the plastic raw material from the melting state into the closed plastic mold cavity.
  5. The liquid flow of the plastic raw material into the plastic mold becomes a solid state after the cooling of the mold inside the mold, and after a certain period of cooling. The molten plastic material is solidified into a plastic product with the same shape as the plastic mold.
  6. Injection airborne template will be closed to the mold open, the injection molding machine to push the plastic mold’s thimble board movement, the mold thimble will mold the mold in the mold of the plastic products to the top of the mold.
  7. The product falls into the column under the force of gravity, or is removed by an automated manipulator.
  8. The injection molding machine controls the closed lock mold to carry on the next work cycle.
