Quality assurance system

Quality policy
The QUALITY POLICY of Tokyo Sokki Kenkyujo Co., Ltd. is to manufacture trustworthy products. It is in line with this policy that the company always carries out quality assurance activities from the customer's point of view. Our idea of products includes not only manufactured objects, but also our sales activities, as well as our installation, measurement, and product services, through which we strive to offer trustworthy products to customers.
Traceability system
We build quality into our products that are to be delivered to customers, check the quality built into our products through inspections, and make sure that our products meet necessary standards for quality and function by sampling and testing our products for their environmental resistance and other properties. Appropriate maintenance and management of measuring equipment and jigs used in these manufacturing, inspection, and testing processes are an essential part of assuring the performance of products, particularly their precision.
We have an established traceability system in place for these pieces of measuring equipment and jigs. We also have our proof standards undergo periodic calibration by public institutions according to the national standards, and carry out regular in-house calibration and inspection on our company standards, as part of our efforts to maintain the performance of our measuring equipment and jigs.
