Tallsen is dedicated to providing customers with exceptional hardware products, and each hinge undergoes rigorous quality testing. In our in-house testing center, every hinge is subjected to up to 50,000 opening and closing cycles to ensure its stability and superior durability in long-term use. This testing not only examines the strength and reliability of the hinges but also reflects our meticulous attention to detail, allowing users to enjoy smoother and quieter operation in daily use.
