A compression molding method for thermostable PET(PolyEthylene Terephtalate) resin and a molten product subject to the compression molding method are provided to thermally stabilize PET crystal at the minimum temperature of 180°C through a compression process. A PET molding member including at least 20% of a degree of crystallinity is provided. The PET molding member having a diameter of 0.5mm is pulverized and processed in the form of a particle or a pellet. The PET molding member is filled in a lower mold(20) heated at the temperature of 220°C to 260°C. An upper mold(10) is pressed. The upper mold forms a predetermined shape in cooperation with the lower mold. The PET molding member has the degree of crystallinity corresponding to 40% or more.
