Abstract

A plastics shaping method, comprises: plastic material in die module being radiated using infrared laser or focusing infrared ray to heat the plastic material and press the said plastic material, in order that the plastic material is distorted into given shape. The said plastic material is permeable visible transparent material added with infrared absorbing material. The infrared laser is radiated using a carbon dioxide gas laser device. The water content of the plastic material is not more than 0.01% by weight. The infrared ray is radiated on the plastic material under the inert atmosphere. The plastic material is selected from any one of polycarbonate, polyester, cyclopolyolefine, acrylic resin, alicyclic ring acrylic resin and olefin-maleimide alternating copolymer. Thus, the plastic material is effectively heated by infrared ray in short time to increase the production efficiency of the product.
