  • Single-stage apparatus and method for producing containers made of thermoplastic material
    Patent number: 6241938
    Abstract: A method of producing parisons of thermoplastic material, which includes the steps of injection of plasticized resin into a plurality of multiple-cavity molds, removal of the parisons from the respective injection molds and transferring parisons to conditioning stations to go through a temperature conditioning phase. The parisons are held in the conditioning stations for a pre-determined length of time, and then the parisons are transferred into appropriate blow molding tools in order to blow the conditioned parisons. Further, during the conditioning phase, the temperature of the surface of the collar of the parison is caused to increase, while the temperature of the parison body is allowed to decrease, so that at the end of the conditioning phase the temperature of the surface of the collar of the parison exceeds by approximately 15 to 20° C. the temperature of the parison body.
