Wunder-Mold is a state-of-the-art technical ceramics company that is well situated in the Northern Californian city of Vacaville, just east of the well-known Napa Valley wine region and roughly midway between Sacramento, the state capital, and San Francisco.Our efforts are concentrated on a range of ceramic and plastic materials, such as zirconia and alumina. This specialization, in our opinion, enables us to thrive at what we do best. Ceramics are exceptionally difficult to mold and machine, requiring unique skills and knowledge.
