Quality Control

hard_top.png

To pursue friction welding technology, we collaborate with universities and research institutions to establish joining conditions and evaluation methods.
Furthermore, testing facilities repeatedly perform static evaluations (tissue observation) in addition to dynamic evaluations (tensile tests).
We aim to improve user confidence and enhance our internal technical capabilities.

Quality maintenance management

In friction welding, the heat input temperature changes depending on the balance between rotational speed and pressure.
Temperature control is a crucial factor in maintaining consistent quality.
Our company equips its processing machines with infrared thermometers, allowing us to manage temperature history and pressure behavior, and provide high-quality, stable products.

Collaboration with research institutions

To pursue friction welding technology, we collaborate with universities and research institutions to establish joining conditions and evaluation methods.
In addition to dynamic evaluation (tensile testing), our testing facilities repeatedly perform static evaluation (structural observation) to enhance user confidence and improve our internal technical level.
