Consistent calibration and performance management of our testing equipment allows us to have highly reliable results. We can identify and analyze any miniscule abnormalities and the root causes to achieve flawless products.     

Best Instruments & Best Quality
A professional quality assurance system and comprehensive quality control processes help us execute each stage of product development, from incoming inspection, first work piece inspection, in-process inspection, and finished product shipment inspection and other processes. Through SPC (statistical process control software) we get to monitor the production process at any time, which can eliminate and avoid any of the abnormalities that may happen, as well as to enhance the quality awareness of the entire factory staff in order to meet the company's quality policy.
