What we wind / Compression springs

Compression springs
Pushes back when squeezed
Open-coil springs that resist being pushed shorter. The most common spring we wind, and the one the calculator on the home page sizes.
| Wire | 0.2 to 6.0 mm |
|---|---|
| Size | Outside diameter 2 to 60 mm, free length up to 300 mm |
| Materials | Music wire, 302 and 316 stainless, oil-tempered and chrome silicon for heat |
| Finishes | Plain and oiled, zinc, passivated, black oxide |
| Quantities | One prototype to production runs |
Options
- Closed and ground ends, so it stands square
- Closed, not ground, for light loads
- Open ends, when it sits on a pin
- Conical or barrel shapes, to stop buckling or nest flat
Where you'll find them: Valves, latches, switches, battery contacts, seat and pedal returns.
Before you send a drawing
- Is there a minimum order?
- Not for samples: one spring is fine. Production runs usually start at a few hundred, because setting a coiler takes the same hour whether it makes ten or ten thousand.
- What tolerances do you hold?
- EN 15800 grade 2 for compression springs unless your drawing asks for tighter. Tell us which dimension matters most and we hold that one closest.
- Will you sign our NDA?
- Yes, before you send the drawing. Yours or ours. Drawings stay on our server and nobody outside the works sees them.

Load and travel, the space it lives in, where it works, and how many. A drawing helps; a used sample also works.
