With existing normal resin plating, because of its low Cr throwing ability, it could not plate areas that is complicated, causing concern about rusting.
To eliminate this problem, painting areas that were not covered by Cr, leading to increase in cost and design restriction.
Cr throwing ability to inside of the pipe shaped materials.

| Condition | Total Ampere(A) | Time(Min) | Cr thickness(μ) | Throwing power(depth) | Improved by(%) | High current area defect |
|---|---|---|---|---|---|---|
| Original | 2400 | 3.5 | 0.33 | 9.0 | ＊ | 0/9 |
| Adjusted | 1400 | 3.5 | 0.36 | 11.5 | 28％ UP | 0/9 |
| Excess Cr | 1800 | 3.5 | 0.41 | 15.0 | 67％ UP | 9/9 |
YUKEN has succeeded to increase throwing power by 28%
*when maximized the throwing ability, burn (Too much Cr losing brightness) will occur.
