  • Patent number: 11931936
    Abstract: In an injection process, molten resin is successively injected from a first flow channel and a second flow channel connected with each other in order into a cavity of a metal mold. High-temperature resin existing in the first flow channel is injected in advance into the cavity as a part of a single shot of molten resin to later form a skin layer of a molded article. Other low temperature resin near a flowable limit existing in the second flow channel is subsequently injected into the cavity as another part of the single shot of molten resin to later form a core layer of the molded article. A low temperature resin remaining in the first flow channel when injection is completed is warmed to be a high-temperature resin before the next cycle, thereby allowing successive molding of molded articles.

  • Publication number: 20060037249
    Abstract: An ascending/descending door glass supporting structure includes a sash, a run channel provided in the sash for guiding a door glass, and a slider provided at a front edge and/or a rear edge of the door glass. An inner first lip, an inner second lip and an inner third lip formed on the run channel are oriented toward a bottom of the run channel, facilitating assemblage of the door glass. The slider has a hook-shaped portion for hooking the inner second lip. The door glass is thus unlikely to escape and is reliably held with a reduced number of parts.
