Molds manufacturing

To achieve the best possible result we use Swiss +GF+ professional cutting machines.
Each produced piece reaches a high level of precision with a tolerance within 3μm.

Striking needle production process

The striking needle is an essential tool for zipper manufacturing. The entire manufacturing process is rigorously controlled. Handle, body and point are engineered and constantly checked. A standard striking needle is obtained by a process of continuous inspection feedback and correction.

Mold copper casting process

A central part of this process relies on the CNC machine input. Data and graphic inputs are carefully loaded onto our CNC machines digital display screens. Our technicians select the correct tools and CAM specs. The copper mold is carefully clamped onto the CNC machine-tooling table where step grinding is performed. Projector quality inspection after tooling assures that piece will couple perfectly with a standard needle.

Zipper molding process

CNC line tooling, coarse and fine grinding are checked constantly with our state of the art projector control system which allows us to detect any inconsistencies and make immediate rectifications. EDM process and tooling are done to specific angles and each stage of the process is checked and eventually corrected by a second projector inspection. The zipper mold process is complete only once this final test is passed and the data from the projector inspection is fully analyzed.
