Application Cases

Representative spring solutions for high-repeatability assemblies.

The following scenarios describe common engineering applications for standard and custom-made springs. Specific customer names are intentionally omitted to protect project confidentiality.

Automotive

Return and preload springs for mechanism assemblies

Feima supports springs used in automotive mechanisms where load curve, fatigue life, surface treatment and batch consistency need to be discussed before production.

IATF-oriented quality communication
Load and stroke parameter alignment
Batch traceability and packaging planning

Medical Equipment

Small precision springs for stable device operation

For device projects, Feima can review stainless material options, dimensional tolerance, surface cleanliness and inspection frequency.

Material and finish discussion
Dimensional inspection records
Sample validation before production

Electronics and Appliances

Wire forms and elastic parts for compact assemblies

Custom wire forming and flat spring structures help fit spring functions into limited installation space while keeping assembly simple.

Space-limited spring geometry
Tooling and process route review
Consistent appearance and fit

Industrial Equipment

Hardware kits for one-package supply

For machinery and equipment buyers, Feima can combine spring parts with related metal accessories to reduce procurement fragmentation.

Combined spring and hardware supply
Packaging protection and labeling
Repeat-order delivery coordination

Testing Evidence

Inspection capacity supports project decisions before mass production.

Spring projects often fail when expectations stay verbal. Feima encourages customers to define critical dimensions, load points, sampling level, surface standard and packaging rules in writing.
