Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Making outline
- Prepare feed: Prepare rod and a pointed end that can enter the first die. Check: End can be gripped; feed is free of major defects.
- Draw in stages: Pull through progressively smaller dies using capstans and lubrication. Check: Wire becomes thinner and longer without breaks.
- Restore ductility: Use appropriate annealing where the process needs softness restored. Check: Wire remains drawable and windable.
- Finish & gauge: Finish to the selected diameter; verify uniformity and spool for coating. Check: Continuous fine wire within the chosen design tolerances.
What remains unresolved
- A coarse steel drawplate is a starting tool; fine wire requires more precise dies.
- Exact grades, quantities, operating parameters, tolerances and complete making dependencies are not finalized.
