Quality control system

We inspect products that have undergone surface treatment, one by one, by visual inspection and weighing. After confirming that there are no scratches, stains, or unevenness, the product is delivered. In addition to manual inspection, we also measure film thickness and surface roughness to provide only good products. We have been particular about the appearance precisely because we have been performing surface treatments related to the decoration of eyeglasses for many years. At present, we also receive requests for surface treatment that takes functionality into consideration, so we have a lineup of analysis and evaluation equipment that analyzes each function such as corrosion resistance, slidability, weather resistance, and wear resistance.

At our company, we record the history of each process in a dedicated database, and operate traceability such as controlling the judgment of product shipment, monitoring product quality, responding to market complaints, and creating quality assurance documents. It is visualized so that members can check it on a weekly/monthly basis, and it is used to improve the site. In addition, the flow from order receipt to delivery is also managed by the production control system.

We have acquired ISO 9001 and 14001, and manage quality and environmental management systems.。
