Quality Control

UltraNode quality control plan:
Our company has a complete quality control system. All products are manufactured under the guideline of ISO9001-2008 and other industry recognized standards, including the re-inspection of raw materials (Titanium substrate, Noble Metal, cable and other Materials), processing inspection (process card, technical procedure), and finished products’ inspection (accelerated life test, Binding Capacity and coating thickness etc).
