  • Manufacturing method for a hood type ventilation device
    Patent number: 11241554
    Abstract: A device for providing a known concentration of blended air and oxygen, or oxygen, to an individual which incorporates a face mask inside a hood, thereby preventing aerosolization of potentially harmful exhaled gases and controlling condensation issues within the hood while under pressurized conditions. The air tight seal required to allow placement and removal of the hood on the individual will be manufactured using injection molded elastomers to over-mold injection molded rigid plastic components.
    Type: Grant
    Filed: May 18, 2021
    Date of Patent: February 8, 2022
    Assignee: CREST MOLD TECHNOLOGY INC.
    Inventors: Edward Helmut Bernard, Will James Cipkar, William Cipkar, Brian Gignac

  • Dual material injection mold and method
    Patent number: 7559763
    Abstract: A two-shot injection molding assembly is provided where the tooling that creates the mold for the first material can be retracted and the tooling that creates the mold for the second material can be inserted. The first material tool blocks the mold area that is intended for the second material to be injected. After the first material is injected into the mold, the first material tool can be retracted and replaced with the second material tool. The second material tool creates a side for the mold that is used to form the second material injected into the mold, and a spring based wedge forms the other side of the mold. By having the first material tool retracted and replaced with the second material tool, the core plate does not have to be rotated.
