Craftsmanship
What only Oya Manufacturing can do
Friction welding
In friction welding, the heat input temperature changes depending on the balance between the rotation speed and pressure.
Temperature control is an important factor in maintaining consistent quality.
We equip our processing machines with radiation thermometers, and are able to provide high-quality, stable products by controlling temperature history and pressure behavior.


Spatula processing
While a circular metal plate is rotated by a machine, a spatula is pressed against it, gradually deforming it from the center to the outside to fit the metal mold (or wooden form), creating the shape.
This is a processing method that requires the skills, experience, and intuition of a skilled craftsman, including delicate touch and the amount of force used.
