Reverse engineering from a sample

What it is

Copying a spring from a physical part when there is no drawing. We do this. It is a confirmed capability, not a marketing line.

How it works

You send the spring — unused if you have one — and say where it lives and what it has to do. We take the dimensions we need to coil a replacement, quote within 24 hours, and make a development piece for you to try. The bulk lot waits on that check.

A used spring has often taken set. Copying its free length blindly will sit short. Tell us the pocket or the load you still need.

When to use it

A broken instrument spring, an MCB part with no drawing, a furniture mechanism whose maker is gone. If the wire is inside Ø 0.40–2.50 mm, it is regular work.

Limits

Wire Ø 0.40–2.50 mm. Usual minimum 5,000–10,000 pcs, with development charges on a smaller run. Rolling-shutter and heavier springs sit outside this range.
