Low pressure injection molding method using recycled PET for package tray of vehicle

摘要

The present invention relates to a low-pressure injection molding method using a regenerated PET resin automobile package trays, the present invention an embodiment of a step by crushing and washing a used PET containers for reproducing the PET flakes, the PET flake and the removal of water, the chain extension step for producing the first and the inorganic fillers added to recycled PET resin, the skin material to the upper mold charged to and smile supplying a recycled PET resin of the liquid through the inlet provided in the lower mold in the mold opening state, by lowering the upper mold and lower mold haphyeong was then cooled, the molded article comprising a skin material and recycled PET resin maintaining a fixed shape, and rising to the upper mold and provide a low-pressure injection molding method using the package tray of the vehicle regenerated PET resin comprising the step of releasing from the mold and the molded article. one embodiment of the present invention According to this example, by using waste PET bottle recycling car package tray Low pressure injection molding, efficient reuse of resources and less environmental burden becomes available, there is a more competitive effects of the product and automobile. ;
