QA/QC Introduction

At the moment, we employ more than 30 QC staffs, with the QC team consisting of engineers, technicians and trained workers. They are responsible for ensuring that manufacturing processes are smooth-running and consistent high quality standards are maintained.

All our materials and components are imported from qualified suppliers. The whole production procedure is completed in-house, with QC at each stage. There are random checks on products, as well as a thorough final inspection before delivery to clients.
