Compression Springs in China
Compression springs should be quoted from working load, spring rate, free length, solid height, end condition, material, and fatigue requirement. Haizol lets you compare Chinese spring factories before samples or production quantities are discussed.
Music wire, stainless steel, spring steel, phosphor bronze, and specialty alloys can all be suitable, but the material only makes sense when it is tied to travel, load, finish, operating environment, and inspection. That is what keeps factories quoting the same spring.
A clear RFQ should include wire diameter, outside diameter, free length, solid height, end style, spring rate, load at length, working environment, surface finish, and fatigue requirement. On Haizol, factory profiles help you check coiling range, heat treatment, grinding capability, load testing, material records, QC equipment, and similar spring examples.
If the load case changes, compare extension springs or torsion springs. If the shape is not a conventional coil, custom wire forms may be closer.
Haizol helps you compare spring factories by measurable capability: coiling range, heat treatment, grinding, load testing, material records, QC equipment, factory photos, and similar compression spring examples.

Frequently Asked Questions
Where Can I Compare Compression Springs Suppliers?
For compression springs, compare factories by the evidence that affects the part: coiling range, heat treatment, grinding capability, load testing, material records, and inspection reports for spring rate and dimensions. Haizol profiles show business verification, license details, machinery, factory photos, claimed certifications, QC equipment, and product examples. For compression springs, load testing and end finishing are the proof points that connect the drawing to the spring rate.
Can I Source Compression Springs Online?
Yes. On Haizol, compression springs can be sourced by submitting one RFQ to relevant Chinese factories instead of contacting each factory separately. The request should include material, special requirements, optional material grade, surface roughness, tolerance requirements, secondary process, and an uploaded CAD, PDF, ZIP, image, or office file, plus the part-specific details factories need for this category: wire diameter, outside diameter, free length, solid height, end style, spring rate, load at length, working environment, surface finish, and fatigue requirement.
What Should I Specify for Heavy-Duty Compression Springs?
Heavy-duty compression springs should be defined by load at working length, spring rate, solid height, end style, material, heat treatment, finish, and fatigue target. The factory needs those values because a larger spring is not automatically a stronger or safer spring.
What Specifications Matter When Sourcing Compression Springs by Size?
For compression springs, define outside diameter, wire diameter, free length, solid height, end style, spring rate, load at length, material, finish, and fatigue requirement. Factories need those values to quote the same spring rather than a visually similar coil.
What Should I Check Before Sourcing Compression Springs?
Before sourcing compression springs, check whether the listed factory shows coiling range, heat treatment, grinding capability, load testing, material records, and inspection reports for spring rate and dimensions. Those details help connect the supplier profile with the drawing, material, finish, inspection, and production requirement.
