What is Spray Transfer Molding?
Simply put, Spray Transfer Molding (STM) is a fast and efficient process to manufacture lightweight composite materials.
The first 60-90 seconds of the process is where the fabric is impregnated outside the mold using a high-pressure spray process, then molded in a compression press. A blank of dry fiber is held by a programmable robot that has an optimized and controlled spray pattern. It is then sprayed using a high-pressure nozzle head atomizing the spray polyurethane, the robot will lay down the impregnated blank into the tool to be fully molded and cured. The process is designed to scale from initial ideation and experiments to actual automotive production components.
