We deliver reliable and safe products through our robust and thorough quality assurance system
At PST we focus on quality from the design stage and carry out production under a rigorous production management system in order to provide customers with high quality products that are safe and reliable.
We have established a thorough inspection system for finished products and guarantee quality in each inspection process while always remaining mindful of our "customer first quality assurance initiatives".
In addition, we implement a unique PST "spiraling-up" of the rigorous standards (design reviews and quality reviews) inherited from our predecessor businesses and utilize these unique standards to guarantee quality when carrying out mass production. We can also provide sample products at an equivalent level of quality as mass produced products. All of our divisions coordinate with the company working together as a whole to provide the highest quality products.
