Quality Control



Raw material control

Full set of raw material test report, self-inspection when forging received.

Process control

Every step during producing can influence the finished product, so we take an extreme

strict control process to avoid those potential risk of unqualified, including heat treatment(outsourced), release the technical data to supplier and sign a contract based on client’s request.

Process 100% inspection

This 100% is not a single word, to realize this, we have paid lots of efforts behind that paper test report.

Progress improvement control

When find problems inside plant, for example, slow or incomplete information delivery causes some faults which have effects on quality or efficiency, will take positive actions to optimize the process.

Established reward and punishment system.

This system can increasingly improve ZBO workmates’ responsibility before goods delivery
