QA testing
Our customers have come to depend on the high quality and consistency of our products. To ensure that SupremeCorqs perform as expected, we have instituted a number of procedures and standards.
Tests for physical parameters, print quality, surface treatment, and extraction/insertion performance are routinely conducted throughout our production process. For a more detailed description, see the charts below.
