An intermediate step to mass production

Vacuum casting, also known as polyurethane casting, is a lesser-known but highly advantageous production method that particularly appeals to small and medium-sized businesses. This method offers a cost-effective series production of plastic components where both small and large parts, as well as high complexity, pose no challenge. Vacuum casting is a method that requires a lot of manual work, and with our dedicated department in China, we have a unique opportunity to offer this at extremely competitive prices.
