Metal pattern

Metal molds are used during variety of plastic molding and pressing processes. They are a vital requirement for the wide range of components used in the manufacture of cameras and lenses. At SIGMA, all work relating to this precise metalwork is done in-house, including design, production and maintenance. This allows us to manufacture a large variety of products at a very high quality and enables the production of small batch series.

When people force metal to act to their liking, eventually the metal will show faults and errors. That’s why we need to listen closely to our materials. Is the metal mold tired? Is the machinery suffering? You require not just a sharp eye but also a gentle hand. It is just like raising a child.
