Vacuum Casting: The Smart Choice for High-Quality Prototype and Low-Volume Production
When speed, precision, and cost efficiency matter, vacuum casting has become one of the most trusted manufacturing methods for product developers. At Sanwo Rapid , we use advanced vacuum casting technology to help businesses transform product concepts into functional prototypes and low-volume production parts with exceptional accuracy. Whether you're developing consumer electronics, automotive components, medical devices, or industrial equipment, vacuum casting bridges the gap between prototyping and mass production. What Is Vacuum Casting? Vacuum casting is a manufacturing process that creates high-quality plastic parts by pouring liquid polyurethane resin into a silicone mold under vacuum conditions. The vacuum removes trapped air bubbles, ensuring smooth surfaces, fine details, and consistent part quality. The process begins with a master model, usually produced through CNC machining or 3D printing. A silicone mold is then created around the master, allowing multiple identic...
