MAINTENANCE TECHNICAL CENTER｜Our Business

Creating new value that goes beyond parts repair and overhaul

The Maintenance Technical Center has long carried out repairs and restoration of parts, production of screws and barrels, and overhauls of manufacturing equipment and machinery. With our accumulated know-how, we work to develop our core overlay welding and thermal spraying technology and to support our customers by adding value to equipment and providing optimal worldwide procurement.

Special Overlay Welding and Surface Treatment

It is possible to repair nitrided and hard chrome-plated screws with overlay welding. We select welding materials such as Stellite and Colmonoy according to the type and purpose of the screw or barrel. This method improves resistance to corrosion, wear, and heat, leading to longer equipment life.

Cutting-Edge "Laser Cladding" Technology

We research and develop the new overlay welding technology, "laser cladding," which uses semiconductor lasers. The Nagoya Factory has a laboratory and performs laser cladding tests for performance improvement and long life.
We propose optimal maintenance and overhauls to our customers through software analysis of hydrostatic stress.

Integrated Overhaul System

Our Nagoya, China, and Thailand factories have an integrated system for overhaul. The system for kneading machines, rotary feeders, and related machines includes disassembly, repair of parts by overlay welding, processing of new parts, restoration, and reassembly. We offer not only maintenance services, but also proposals for performance improvement and long life based on data analysis.
