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.
BASF's Spray Transfer Molding Process
What is the benefit of using this technology?
Smart Fortwo Exterior Roof
The first exterior car part featuring a honeycomb sandwich structure with a class A film. An example of Spray Transfer Molding technology from BASF. It is 30% lighter than the standard roof on the previous model.
What type of applications would be suitable?
Spray Transfer Molding can be used in a variety of applications and industries ranging from automotive to construction to consumer to industrial manufacturing. We have some production applications for automotive that include door interiors, arm rests, load floors, sun shades, hatchbacks and package shelves.
