Quality Assurance Structure

Basic Stance/Policy

Quality Assurance Structure

THK has established a quality assurance structure in which each production facility in and outside of Japan is certified with the ISO 9001 Quality Management System. We also work with each of our suppliers to accomplish environmentally conscious manufacturing that takes ESG and the SDGs into consideration.
In order to continue improving the quality of our products, we perform the following ongoing activities.

1. Strengthening design quality

As part of managing our product development process, we review the solutions implemented for any issues during the planning, design, prototype, trial, and mass-production stages, and we work to manage the stability and maintenance of quality levels after mass production.

2. Strengthening product quality

We have established a system that allows quality data to be shared globally. Additionally, we gather feedback from customers in each region and analyze it to provide rapid and appropriate service as a manufacturing and innovative services company. In all, we endeavor to develop products that meet market needs and improve quality.

3. Strengthening production quality

We endeavor to enhance the quality of the measurements we take, keeping error to a minimum, by implementing optimal measuring equipment necessary for maintaining product quality.

4. Strengthening talent development

In order to make products that are reliable and safe, we strive to develop talent in the areas of product knowledge (technology), equipment handling (technique), and optimal production (quality).
