Spring
Our springs are high-quality springs made by standing treatment, manual sand removal, and other processes. Through our unique process, our springs can reach durability of at least 300,000 times, and some springs can reach durability of 1 million times (depending on the type and material of the spring). Excellent quality has made us a foundry for many European and American markets (due to non-disclosure agreements, we cannot show evidence). In order to prove our strength and reputation, we also support sample testing and look forward to your inquiry.
