Dies tooling
Zaninelli was founded in 1938, but since 1969 it has specialized in the construction of hard metal elements for the creation of dies used in magnetic laminations cutting. In 1984 Zaninelli began to build Tungsten Carbide dies for the production of magnetic laminations for small motors, transformers, contacts etc. In 1991 Zaninelli expanded the range of products by making dies with automatic stacking systems.
Today the company has 25 specialized employees with years of experience in dies construction behind them. Thanks to the experience of highly qualified staff, the company uses CAD-CAM technology and the latest generation machinery necessary for the production of modern blanking dies.
