  • Patent number: 5985188
    Abstract: A method and mold design for forming a molded chair seat portion and chair back support portion using air counterpressure and two different materials in an injection molding procedure. The two different materials comprise a first material having a low flexural modulus and the other material having a high flexural modulus. Other additives for tailoring the physical properties of the molded product are added to the mixture of the two materials. The air counterpressure is achieved using shop air pressure. The mold may be used to form the seat portion and the back support portion with a single stroke. An endothermic foaming agent is added to the mixture of the two materials to reduce the weight of the finished part, to reduce cycle time, and to assist in the uniform distribution of the materials that are injected into the mold cavity by the injection nozzle.
