Shanghai Guanglei Spring (GL Springs) manufactures custom springs for industrial machinery and equipment that must perform under heavy loads, high cycle counts, and demanding operating conditions. From valves and pumps to stamping presses and hydraulic systems, we engineer compression, die, tension, and torsion springs to your exact load, dimensional, and durability requirements — backed by 20+ years of manufacturing experience and IATF 16949 certification.
Case Details
What Industrial Machinery Demands Springs in industrial equipment have to deliver: - High load capacity and long fatigue life under continuous operation - Dimensional consistency for reliable, repeatable machine performance - Resistance to corrosion, heat, and harsh operating environments - Custom and large-format sizes that off-the-shelf springs can't provide
Applications in Industrial Machinery Our springs are used throughout industrial equipment, including: - Valves & pumps — pressure-relief valves, check valves, regulators - Stamping presses, dies & molds — die springs for tooling and metal forming - Hydraulic & pneumatic systems - Compressors and motors - Conveyor and material-handling systems - Clutches, brakes, and actuators in heavy equipment - Vibration isolation and damping assemblies
Materials & Capabilities - Materials: alloy spring steel (Cr-Si, Cr-V), oil-tempered wire, stainless steel (304/316) - Wire diameter range: up to 35 mm for heavy-duty springs - Custom sizing, including large-diameter and high-load springs - Surface treatments: zinc plating, Dacromet, black oxide, powder coating - In-house testing: load testing, fatigue testing, salt-spray Why Industrial Customers Choose GL Springs - 20+ years (since 2005) of precision and heavy-duty spring manufacturing - ISO 9001 & IATF 16949 certified, with material traceability - Wide material and size range — from micro springs to large industrial springs - 7-day sampling, from prototype to high-volume production - Engineering support to optimize load, durability, and cost
