PLAST MAC therefore treats mold maintenance as a dedicated service with a professional, experienced team. The service covers all types of molds, whether they were manufactured at PLAST MAC or outside, while maintaining their basic specifications. The department also carries out all types of periodic and preventive maintenance. This saves the time, effort and maintenance cost of sending molds back to their country of origin, which is important for customers who own imported tooling.

Repair work relies on the same mold shop that builds new molds. That shop includes CNC milling, spark-EDM, wire-cut, grinding, and laser and argon welding equipment. Maintenance is done using ultrasonic welding and argon welding, techniques that allow worn or damaged areas to be rebuilt and returned to their original dimensions. A spare parts warehouse was established inside the mold workshop to collect all the critical spare parts needed during manufacturing and maintenance, so repairs are not delayed while waiting for components.

Regular maintenance protects the injection and extrusion lines. A mold in good condition produces parts with stable dimensions and appearance, reduces rejects and helps avoid unplanned stops on the machines. The maintenance service is not limited to the company's own production. It is offered to customers and to other manufacturers whose molds were made elsewhere. Preventive schedules, an in-house spare parts stock, skilled technicians and complete workshop equipment make the mold maintenance department a reliable partner for keeping molds productive over a longer lifetime.

Molds are valuable assets that must be maintained regularly.
