摘要： There is provided a process for producing a multi-layer molded product having a plurality of thermoplastic resin layers. This process provides for (i) a step of supplying first and second molten thermoplastic resins each through first and second resin supplying gates which are temperature-controllable independently of each other, to between female and male molds kept in an open state with a time difference being provided between supply starts of the first and second resins, and (ii) a step of closing the female and male molds after completion of supply of the first and second resins. The process enables production of high-quality multi-layer molded products having a plurality of resin layers with good repeatability under relatively low resin supply pressure and by single mold closing. Further, high-quality multi-layer molded products can readily be produced without restrictions on materials used.

摘要： A hollow molded article having no sink marks on its surface and having an excellent appearance is produced by filling a mold cavity with a resin being in a molten state and then ejecting at least a part of the resin by sucking through a resin-ejection opening and introducing gas through a gas-introduction opening into the resin inside of which being in a negative pressure. According to this process, the use of a high-pressure gas is not required.

摘要： A process for producing a hollow article in an assembly comprising first and second mold members movable relative to each other between a closed position in which an inner surface of the assembly defines a cavity and an open position. The cavity is shaped to define a corresponding configuration to the article. According to this process, a charge containing at least one molten thermoplastic resin is supplied at the first and/or second mold member while the mold members are not in the closed position. The first mold member is moved relative to the second mold member into the closed position so as to define the cavity, and a first clamping force F1 is applied to the first and second mold members. The charge is then compressed within the mold cavity under the first clamping force F1. Thereafter, the clamping force is reduced from the first clamping force F1 to a second clamping force F2 before the molten thermoplastic resin in the mold cavity has completely solidified. A compressed gas is supplied into at least one unsolidified portion of the molten thermoplastic resin subsequent to the step of closing the mold members and before the molten thermoplastic resin in the mold cavity has completely solidified. The molten thermoplastic resin can then be cooled in the mold cavity and solidified while supplying the compressed gas.
