Conical Compression Spring Progressive Force Variable Diameter Custom

Conical Compression Spring Progressive Force Variable Diameter Custom
Conical compression springs feature coils that gradually increase from top to bottom, providing progressive force characteristics within limited height constraints.
Compression Spring Quick Detail
Conical compression springs provide progressive force—soft initially to absorb light shock, then increasing stiffness for rigid stop. Solid height is extremely low, saving installation space. Custom top/bottom OD, free length, and force curve available with 48-hour sampling.
Compression Spring Product Description
Unlike standard cylindrical springs, conical springs achieve a final solid height just slightly greater than a single wire diameter as coils sequentially bottom out—dramatically saving vertical space. The progressive force characteristic offers unique advantages in battery contacts and shock buffers: low initial force for easy battery insertion; high final force for reliable electrical contact or rigid support.
Tingfeng Hardware precisely designs taper ratio and pitch distribution to achieve specific force curves. Using CNC spring formers for direct manufacturing eliminates tooling requirements. We can reverse-engineer designs from target forces at different compressed heights or manufacture directly from CAD models. Small batches from 100 pieces with 48-hour sampling and 15 years of spring manufacturing experience.
