Solution results - Individual

We would like to introduce the following solution results of the functional, quality, and cost improvement by our advanced finishing and plating technology.

Rust occurred after plating on iron

Company LL had a trouble with a rust occurred after plating on iron. They could not solve this
by adding under layer plating and change the specifications by some other company. Then they asked our help. We observed and analyzed the rusty surface with EDS (Energy Dispersive X-ray Spectrometry), we found the particles derived from the barrel polishing abrasives.
We proposed the change from the barrel polishing process to our pretreatment on the ground, because the media attached to the material affects the rust after plating. Finally we were able to prevent the rust.
