Coil Supply for Electronics and Precision Hardware

Below about 0.3 mm the supply problem changes character. Ordinary service centres stop carrying stock, tolerance and flatness start to govern whether a progressive die runs at all, and the parts are usually narrow enough that buying wide coil means paying for scrap.

Where It Goes Wrong

  • Stock below 0.3 mm is not held locally and mill minimums are far above annual usage
  • Strip arrives out of flat and jams a high speed progressive die
  • Springback varies between deliveries because temper was never specified
  • Narrow parts are blanked from wide coil and most of the strip becomes skeleton scrap

What the Sector Actually Needs

  • Reliable supply below 0.3 mm and down to 0.05 mm
  • Defined temper so springback is repeatable
  • Slit width matched to the die rather than to a stock size
  • Flatness good enough to feed at speed

Typical Applications

  • Shielding cans and frames stamped from thin stainless
  • Contacts, clips and springs at a defined hard temper
  • Shims and spacers below 0.2 mm
  • Anodized aluminum bezels and visible trim

How We Deliver Into This Sector

  • Gauge from 0.05 mm on stainless and on the DC ladder
  • Slit width from 5 mm, so narrow parts stop generating skeleton scrap
  • Temper specified per order rather than inherited from stock

Electronics and Precision Hardware Questions

What is the thinnest strip you can slit narrow?
0.05 mm, and it can be slit as narrow as 5 mm at that gauge on the stainless and DC families.
How do I get repeatable springback?
Specify the temper, not just the grade. Two coils of the same grade at different tempers behave completely differently in a forming die.
Why does flatness matter more at thin gauge?
A high speed progressive die has very little tolerance for shape in the incoming strip. Coil set and edge wave that would be invisible at 1 mm will stop a line at 0.1 mm.
