  • Method for localized preform cooling outside the mold
    Patent number: 6770239
    Abstract: An apparatus and method for providing targeted cooling to a pre-molded article, such as a preform. A cooling pin is inserted into the preform such that it makes contact with targeted area, such as the mold gate area. This permits conductive cooling of the targeted area. The apparatus and method are particularly suited to post-mold cooling in conjunction with a robotic take-out plate.

  • Compact post-mold cooling device and method for thermally conditioning molded articles
    Patent number: 6139789
    Abstract: The present invention relates to a multi-stage, post-mold cooling method and apparatus used in conjunction with an injection molding machine having an aggressive cycle time and a high output. The apparatus of the present invention includes a thermal conditioning device/station with cooling tubes for keeping separate the preforms of each batch and effecting cooling of the molded preforms, several separated cooling levels for simultaneously cooling multiple batches of preforms, and internal devices for automatically transferring each batch of molded preforms from one cooling level to the next. In a preferred embodiment, the thermal aconditioning device/station is partially sealed to create a controlled temperature environment for conditioning the molded articles. In another embodiment, the thermal conditioning device/station includes a level for re-heating the preforms.
