摘要： The invention relates to a method and a device for producing a hollow body (7), especially a heat-resistant hollow body, which is shaped from a heated preform from a thermoplastic material in a contoured blow mold (2). For this purpose, a first medium is fed to the preform, said medium being stored in a first medium reservoir (32) and being subject to a pressure p1 (pre-blow phase). At approximately the same time the hollow body is stretched by means of a stretching rod (6) and a second medium is fed to the hollow body, said medium being stored in a second medium reservoir (33) and having a pressure p2 which is higher than p1 (final blow phase). The hollow body is shaped by said second medium and cooled by a third medium which is stored in a third medium reservoir (rinse phase). The pre-blow medium is maintained at a pressure of 2-20 bar, the final blow medium at a pressure of 15-45 bar and the cooling medium at a pressure of 30-45 bar.

摘要： A method for producing a biaxially oriented, heat set plastic container, including the steps of providing a plastic perform whithin a mold cavity; expanding and stretching the plastic preform into conformity with the surfaces defining the mold cavity to form abiaxially oriented plastic container; inducing crystallinity in the plastic container by using convection heat transfer to heat a surface of the plastic container to a temperature of at least 120 °C; and removing the plastic container from the mold cavity. The PET containers produced by the method have an average sidewall crystallinity greater than about 30 %, which allows the PET container to maintain its material integrity during any subsequent pasteurization or retort process of the contents in the PET container, and during shipment of the PET container.

摘要： A method for producing a hollow molded article having a skin material comprises steps of: (a) providing a skin material between a first mold and a second mold which are in an open state; (b) supplying a molten thermoplastic resin between the first mold and the second mold; (c) closing the first mold and the second mold; (d) inserting a first hollow pin into the molten thermoplastic resin and supplying a gas into the resin through the first hollow pin to form a hollow part; (e) inserting a second hollow pin into said hollow part and supplying the gas through the first hollow pin while discharging the gas through the second hollow pin, thereby to circulate the gas in the hollow part to cool and solidify the molten thermoplastic resin; and (f) opening the first mold and the second mold and taking out the hollow molded article. A hollow molded article with a skin material can be efficiently cooled by means of a simple apparatus and operation without using a complicated apparatus or a special cooling material. Further, a hollow resin molded article having a skin material can be uniformly cooled in a short time without temporarily reducing the pressure in the hollow part and, therefore, a hollow molded article with a skin material free from distortion can be obtained.
