Quality Control
Nothing undermines a good partnership like unexpected defects or performance issues. We’ve heard the stories of distributors scrambling when a shipment of hinges fails on the job. At TDC, we take Quality Control seriously so that nightmare never happens to you. Every hinge we ship has passed through multiple inspections and rigorous tests. Our goal is simple: hinges that work perfectly the first time, every time.
-
Multi-stage inspections:
We check raw materials on arrival, monitor processes on the floor, and inspect finished hinges before packing.Stress and durability testing:
Hinges undergo load tests, salt spray tests, and cycle tests to ensure they can handle real-world use. -
Full traceability:
Each batch is tracked with batch numbers and reports, so we know exactly where every component came from.Certified processes:
Our systems follow ISO 9001 quality management, AQL standards, and strict 6S shop floor controls.Continuous improvement:
