Bright Annealing Machine Purchase

Last month we hav bought a new machine for bright annealing process.

It is constructed at our Tanuma plant, a few kilometers far from our main plant. 

Bright annealing is an annealing process. 

This reduce the oxidation surface and result into a clean and brighter surface. Moreover, it is better resistance in corrosion. 

Please see the picture below.


Our main weldings process are “spot welding” and “seam welding”.

When welding, the surface is oxidized. One of our customers were concerned about these oxidization. Therefore we proposed a solution of bright annealing.
