Compression Spring ,

Manufacturing compression springs for all industries from industrial to electrical to transportation, SINLESAN can produce custom pieces for your specific requirements. With the capacity to produce springs in both left hand and right hand directions, using exotic metals like Inconel, Monel, and Elgiloy alloys, you can be sure that we’re up to the challenge of any application you may have. We can produce springs in any form: standard barrel springs, or conical, hourglass, or variable pitch, with multiple spring end options: open or closed ends, ground or squared. In addition, we manufacture springs with free lengths from 0.100 in. (2.54 mm) to 40 ft. (12.192 m), coil diameter from 0.060 in. (1.524 mm) to 4.0 in. (101.6 mm), and wire diameter from 0.008 in. (0.203 mm) to 0.375 in. (9.525 mm), working to SMI tolerance standards.


We know that inventory management is important for costs and efficiency, and so we offer Kan-ban and blanket ordering schedules, as well as J.I.T. delivery. Our shop can produce in high or low quantities: one unit to runs of one million, using our CNC coilers, grinder, and wire bender. We accept files and drawings in .dwg and .dwz (AutoCAD) formats, STEP and IGES, as well as standard files like .bmp and .jpeg, so contact sinlesan hardware spring co.,ltd today to discuss your needs.
