Hongdaer really cares about quality. In fact, as evidenced by the diagram, the control phase involves the entire production process.




At each step checks of the dimensions are carried out with certified equipment and state of the art machinery. The first check involves the tools that are used during production. This control is carried out through a presetting for the analysis of the profile




In the meantime there is a parallel acceptance process for the raw material (rods, brass rods, forged parts, etc.).During the processing phase there are two types of controls. The first is conducted by the machine's operator




At the same time, every half-hour samples are collected and analyzed with appropriate monitoring tools like vernier calipers, comparators, rings and pads. If it is necessary to analyse specific pieces a Zeiss three-dimensional measuring machine is used which has a measurement accuracy of one hundredth of a millimeter.
