The mold making studio is the heart of the manufactory. This is where the plaster molds are made for the casting of figures as well as objects that cannot be thrown on the potter's wheel. Manufacturing requires a large degree of know-how and a high level of technical skill. Large and complex Nymphenburg designs must be cast as individual elements and then assembled, retouched and engraved to become the desired whole. A separate plaster mold is made for each element, which can then be used up to 15 times. Each piece is cast from a mold and then painstakingly retouched by hand. While the bottom of the plaster mold generally consists of one piece, the top is divided into several wedges, each reflecting a space without undercuts. They can be removed one by one after casting.This is the only way to ensure that the fragile porcelain can be removed from the mold undamaged.
