Service

Support across the full cycle, from custom design to spare parts

  • Built to the machine

    Give us the machine brand, tonnage and mounting interface. We match the dimensions so the part installs on the existing machine.

  • 100% factory test

    Parts are checked against the drawing on a CMM before assembly. The finished unit does not ship until our own bench has recorded a full performance curve.

  • Delivery and logistics

    Standard models are kept in stock. Custom parts ship to the production plan. An inspection report and packing list go out with every delivery.

  • Service and spare parts

    Technical support and wear parts are available through the warranty period, and batch test data can be traced by serial number.
