Chen's Copper has been attaching great importance to quality control of its products, with the view of making a contributionto society by producing high-quality products.

The first step to product quality control is to determine the users' demands for product quality in design stage. After setting the target, we aim at producing the products that are consistently high in quality and can meet the standards that we set. We believe that each process of production is equally important, and we carry out various tests such as design check, process control, in-line testing, finished product testing, and inspection before shipment.
