An orthodontic bracket is primarily made by Metal Injection Molding. Metal injection moulding mixes fine metal powder with a binder, injection-moulds it like plastic, then debinds and sinters to near full density. Below is the full route to make an orthodontic bracket, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How an orthodontic bracket is made
The usual route, raw material to finished part. The amber step is where the orthodontic bracket gets its basic shape.
Powder and tooling
Blend the metal powder and make the compaction die or mould.
Metal Injection Molding
Injection-mould the powder-binder mix, then debind to a green orthodontic bracket.
Tooling High (mold) Tolerance ±0.05 to 0.3mm Lead 12 to 20 weeks
Sintering
Fuse the particles below melting point so the orthodontic bracket reaches full strength.
Sizing
Coin or re-press for final dimensions.
Secondary machining
Machine any features the die could not form.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Heat treatment
Harden or steam-treat to the needed properties.
Tooling n/a Tolerance can distort Lead days
Finish
Plate or impregnate for corrosion resistance or sealing.
Tooling Low Tolerance adds microns Lead days
Inspection
Check density, dimensions and hardness.

Cost
What an orthodontic bracket should cost
Small, complex, high-density metal parts (like plastic injection, but metal); needs volume to pay the mold.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for an orthodontic bracket at your volume, in your currency, are in the dossier.
