Many items produced require specific treatments to obtain the high quality characterizing them: these treatments are done in the tumbling department, where components are processed by wet and dry tumbling, using updated technological solutions, also during these stages.

An example of this is the modern plant for cryogenic finishing that solves the typical problems of thermoplastic material injection process.

In this department, an accurate control of the component’s surface takes place, which is supported by high precision equipment, such as surface roughness tester that enables obtaining the best surface definition for the following processes.
