Latest Patents

Johnson holds a patent for a "Pin-in-sleeve device for in-article gas assisted injection molding." This device is designed to be readily replaceable and is utilized with a two-part mold to create injection molded products from plastic materials. The device features a sleeve with a threaded exterior surface that fits into a mold member's socket, leading into a mold cavity. A longitudinally extending bore runs through the sleeve, which has two portions: one adjacent to the cavity and a larger diameter portion spaced from it. A pin extends through the sleeve, creating a tortuous path for injection fluid, which helps prevent plastic material from entering the device when the fluid is vented. Additionally, a filter positioned in the bore behind the pin ensures that traces of plastic material are filtered from the vented injection fluid. The device can be quickly unscrewed from the mold member using a simple tool, such as a socket wrench.
