Quality

We have obtained ISO 9002, confirming our insistence on quality. We have achieved QS-9000, and TS-16949 showing our determination to improve our products continuously.

Quality control

The quality Assurance Dept. take charge of the supervision of quality, they inspect every step before delivery, such as : purchase of raw materials, arrival of materials, process and finish goods.
We make use of all kinds control method, such as: CPK control, defects control, in order to assure that our prodcuts are conformed to the quality request. We keep the quality management of the process, trace of products, other related quality information and records completely on file, so that we can provide a professional consulting service to the quality.

We make every endeavor to do still better, and train professional staffs to control the quality, and have a Taylor Hobson of England, a precision cylinder measuring machine and surface rough measuring machine for controlling the quality precision, and providing a complete professional quality information.

Maintenance and management of Inspection Instrument

To assure the precision of the measuring instrument and its life span, the instrument should be maintained and corrected regularly by professional staffs.
The related correction of quality could be traced to the national laboratory.
To lessen the error of measurment, the cylinder measuring machine and surface roughness meter should be placed at the quality assurance laboratory (temperature and humidity are controlled day and night).
