TT-03/TT-03(B) Main features: TT-03 / TT-03 (B) is made by special double screw by sizing agent, designed for PET injection molding. Efficient mold release, and improve the processivity The resistance of PET injection product is reduced by 40 - 60% , which greatly reduces the probability of release scratch of the product , and effectively improves the yield rate . Improve the PET fluidity , improve the ejection pressure and shorten the molding period. Maintain the original
