Spring Quality Assurance and Inspection Planning
Quality planning starts at RFQ: dimensions, function, load or torque values, inspection reports and packing requirements should be confirmed before production.
Dimensional Inspection
Wire diameter, outside diameter, free length, formed angles, hook geometry and critical features can be reviewed for inspection planning.
Load Testing
Compression and extension spring loads can be checked at specified heights or lengths when required by the drawing.
Torque Checks
Torsion spring torque at angle can be discussed when torque is a critical functional requirement.
Report Requirements
Inspection reports and project documentation should be requested during RFQ so measured items and sample approval needs can be planned before production.
Sample Comparison
When drawings are incomplete, sample comparison can support early review before final specifications are confirmed.
Batch Consistency
Drawing revision, material, process route, inspection points and packing requirements should be confirmed before batch production.
Quality System References
Supplier website company overview references ISO 9001:2015 QMS and ISO 14001:2015 EMS dual-system certification. Certificate scans or order-specific documents should be attached during supplier confirmation when a buyer requires them.
Inspection Equipment Basis
The supplier website lists more than 20 inspection machines, including numerical automatic tension/compression spring testers, image measuring instruments and spring life-test equipment.

Plan inspection requirements before quoting.
Share drawing tolerances, load or torque values, report requirements and sample approval needs with the RFQ.
Frequently Asked Questions
Can inspection reports be requested?
Yes. Report requirements should be included during RFQ so measured items, sample approval needs and documentation can be planned.
What spring tests can be discussed?
Dimensional checks, load testing, torque checks, life-test discussion and functional fit checks can be reviewed by project.
Are certifications guaranteed for every order?
The supplier website references ISO 9001:2015 QMS and ISO 14001:2015 EMS systems. Order-specific certificate copies, inspection reports or compliance documents must still be confirmed during RFQ.
