Multi-station reaction injection molding apparatus, and method, are disclosed for in-place foaming of polymerizable resins in articles advanced along a production line, as for example in the manufacture of insulated appliance housings such as refrigerator cabinets. The articles are selectively diverted from a feed conveyor, one to each of a plurality of pour stations adjacent the feed conveyor. At the stations, injection of foamable resin mix is accomplished by reaction injection type molding heads which combine at least two liquid resin components. Thes...
The method of effecting multiple-station in-place foaming of reactive polymeric resin composition in articles advancing along a production line, which comprises the steps of advancing said articles along a path and diverting them selectively to one of a plurality of pour stations located adjacent said path as such stations become available to receive an on-coming article; providing at each pour station a mixing head of the reaction injection molding type; providing at least two reactive polymerizable component circulating systems, each such system compri...
