Engine Valve Compression Springs

L&I metal springs Co.ltd. established in 1998, located in xiamen Fujian, With 20 years’ development, we grows into a modern enterprise specializing in researching, designing, manufacturing, sales and service of metal products springs. Our website: www.limetalsprings.com.

Our engineers are fully experienced in product design, spring design analysis, dynamic simulation, and the application of advanced technology to produce innovation. We use a variety of software for spring design, modeling and assembly, and FEA to optimize performance. We use 2D dynamic motion software, 3D dynamic simulation modeling software (ADAMS), solid modeling (NX), 2D drawing software (NX, ProE, ACAD), and spring design tools (IST, SMI, PAC). The latest improvements are on: advanced high tensile materials, nitriding and piece hardening, ovate and multi-arc wire sections, Beehive spring configuration, and advanced surface-finishing processes.

Whether you need Engine Valve Compression Springs for a motorcycle with an 18,000 RPM engine or a low-horsepower engine, We have the technology and the know-how to match you with the proper valve spring to meet your needs.
