    Manufacturing Quality

    We adhere to work procedures that have been designed based on specified drawings and comply with various quality control measures, while striving for the production of high-quality goods and preventing the circulation of defective products. In terms of dimensions, an accuracy of 5/10,000 millimeters is required to produce exceptional parts. Accordingly, we carry a precision measurement room along with calibration facilities for ultra-high-precision measuring instruments, and employ qualified personnel to manage and evaluate product precision.
