MAINTENANCE DEPARTMENT
For routine maintenance and repairs of all systems, a special department has been set up with various rooms totalling 600 sq m of floor space. The department has a lathe, radial drill, reciprocating saws, manual tools and all other equipment required to restore operation when our machinery breaks down or is damaged, attending to both mechanical and electrical problems, to keep all systems working with the utmost efficiency. We keep all the most important and critical parts and spares of each machine in stock. We have two full-time maintenance technicians with years of experience in the specific dished heads field, and hence familiar with the machinery used to manufacture them.
