Mold Maintenance & Repair Services — by KVOTA

Stable plastic production is impossible without regular maintenance and high-quality mold repair. At KVOTA, we specialize in comprehensive repair, preventive maintenance, and modernization of molds, including those with hot runner systems (HRS).

We service tools for injection molding and perform EDM (electrical discharge machining) and CNC-milling operations to restore the geometry and functionality of the molds.
