LOW-PRESSURE INJECTION MOLDING METHOD OF A PACKAGE TRAY OF A CAR USING RECYCLED PET RESIN CAPABLE OF IMPROVING THE QUALITY OF PRODUCT BY RECYCLING A PET CONTAINER

摘要

PURPOSE: A low-pressure injection molding method of a package tray of a car using recycled PET(PolyEthylene Terephtalate) resin is provided to reduce the cost by simultaneously injecting a surface material and a base material to the low pressure.;CONSTITUTION: A low-pressure injection molding method of a package tray of a car using recycled PET resin comprises the following steps. The waste PET container is crushed and cleaned. A PET flake is played. The moisture of the PET flake is removed. The crosslinking agent and inorganic filler are added. The regeneration polyethylene terephthalate(2) is manufactured. The surface material(1) is charged in an upper mold(20). In the finely opening state of the front mold, the liquid regeneration polyethylene terephthalate is provided through the feed hopper(31) of a backmold(30).;COPYRIGHT KIPO 2012
