Injection Molding of a Car Exterior Body

MRC is a leading supplier of reaction injection molding and other services for a variety of industries. The automotive project highlighted here consisted of designing and molding the exterior body of a Ford GT. MRC was one of only a small number of companies in North America with the capabilities and expertise to support this project. An expertly trained team co-engineered the design of the parts, and seasoned technicians made the mold, performed reaction injection molding, and provided trimming and prime prepping of the parts. Advanced 90 to 150 ton RIM presses and a metering unit were used to manufacture the parts, which included front and rear bumper covers, side claddings, rockers, spoilers, and chin splitters all designed to give the car its shape and appearance. The parts were composed of Bayflex 180 O5S with a thickness of 0.125". This material was used for its superior heat and strength properties and ability to withstand the rigorous forces from elevated car speeds. The parts weighted from 5 to 22 lbs. with finishes of base/clear, Class A top coat, and natural color. All work was done to customer specifications with part weights tracked throughout and filler content confirmed. The project represents a total run of multiple pieces for 4,500 vehicles which were delivered in 24 weeks.
