Factors affecting the quality of hardware products。

For example, aluminum sheet metal case cuting by laser machine, or cut by other machine, usually have scratch edges.

So we have set QC to inspect the metal enclosure during production process.

And usually check from scratch, uneven cutting, deformation, oxidative rust, size deviation, too large R angle, surface concave, insufficient chamfered corner, welding scar, color difference, discoloration, cracking, pitting, stacking paint, shadow, exposed bottom, fisheye oil, peeling, color difference, glossiness, hand print, hard scratch, soft scratch.
