Quality Assurance

We assure our precision quality by rating our products with the world’s highest level of measurement environment.

In precision manufacturing, it is essential to guarantee its quality by applying reliable inspection tools.
TDC guarantees all accuracy such as Roughness, Flatness, Parallelism, and Tolerance by inspecting all products during the process.
All data will be sent with the item for Quality assurance.

TDC`s Quality Assurance

We pack the product and measurement data carefully, together with our sincerity, hoping they will meet the needs of all our customers.
We will continue to improve our quality in every aspect, not only in accuracy of the products and in evaluation technology, but also in careful and prompt customer service, price and delivery time.
