Cylindrical compression springs in coloured finishes for model kits, craft projects and consumer products where the spring is deliberately visible. Colour is applied as a coating, so the spring works mechanically first and looks the part second.
Coloured coatings are matched at sampling, so a product family that uses several colours gets a consistent set.
Fine wire down to 0.1 mm covers the spring sizes model and craft products actually use.
Different colours for different rates lets an assembler pick the right spring without measuring it.
Keep coloured springs separated by rate in storage and on the line. The colour is only useful as a code if the coding is maintained through the whole process.

Dimensional and load figures are set per order against your drawing or sample, so they are marked TBC rather than filled with catalogue numbers.

Available in Stainless steel, Spring steel, Carbon steel, 65Mn, Music wire, in wire from 0.1-8 mm, with any of our nine surface finishing routes. Geometry, end treatment and finish are all specified per order.
ISO 9001, SGS certificate and RoHS report (stated on the legacy site, certificates pending re-confirmation). Certificate copies are sent on request once re-confirmed.
Against plated springs, coloured coatings cost slightly more and are chosen when the spring is part of what the customer sees. Mechanically the two are equivalent.
Colour matching is confirmed on samples, since coated colours vary between processes and batches.
Not meaningfully at these sizes, though a heavy coating can affect fit in a very tight bore. We take it into account.
Yes, and it is a sensible way to prevent assembly mix-ups on a product with several similar springs.
