Target Audience: This technical guide is written for automotive distributors, engineers, repair workshops, and OEM buyers sourcing replacement gas springs or custom lift supports.

The Importance of Certification

When purchasing highly pressurized pneumatic components in bulk, consistency is critical. A single defective seal can cause a heavy industrial door to fail. This is why strict gas spring quality control is the first thing B2B buyers should look for in a factory partner.

Decoding ISO/TS 16949

ISO/TS 16949 is the premier quality management system for the automotive supply chain. Factories holding this certification demonstrate robust defect prevention and statistical process control. For a gas strut factory, this translates to automated laser welding inspections, 100% force testing before shipping, and continuous improvement in seal longevity.

Our Testing Regimen

At Yueli, quality is built into the assembly line. Our testing laboratory subjects our struts to 500-hour salt spray tests for the QPQ surface treatment, extreme temperature cycling from -40°C to +80°C, and fatigue tests exceeding 50,000 continuous cycles to ensure zero pressure loss.
