Focusing on the nature of recycling and recycling of PET products, repeated experiments and research and development of new screw structure, the material is sheared at high speed in the barrel, and the multi-stage unique shearing method enables the material to be rapidly plasticized in a short time without drying and crystallization. At the same time, the innovative and automatic automatic exhaust device is designed to automatically eliminate the moisture and moisture of the recycled materials during the operation of the main engine, successfully solving the problem of agglomeration and bubbles in the production of products, and has made a major breakthrough in PET recycling to reach materials. ** recycled material, and does not require the world's most advanced level of dry crystallization.
