A micro forceps 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 a micro forceps, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a micro forceps is made
The usual route, raw material to finished part. The amber step is where the micro forceps gets its basic shape.
Material
Cut martensitic stainless bar (420 or 410 grade) sized for the micro forceps.
Metal Injection Molding
Form the blank (both halves of the instrument).
Tooling High (mold) Tolerance ±0.05 to 0.3mm Lead 12 to 20 weeks
Trimming
Trim the flash and pierce the rings, bows or finger holes.
Milling the pattern
Mill the box lock or joint, the shanks, and cut the serrations, teeth, ratchet or cutting edge.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Assembly
Fit the two halves at the box lock and set the pivot with a rivet or screw.
Hand fitting
File and fit by hand so the jaws meet, the edges shear and the ratchet engages cleanly: the skilled fitting step.
Heat treatment
Harden and temper the working ends for wear resistance and spring.
Tooling n/a Tolerance can distort Lead days
Grinding and polishing
Grind the profile and satin or mirror polish the micro forceps.
Tooling Low (wheel) Tolerance ±0.002 to 0.02mm Lead days
Passivation
Passivate or electropolish to restore the corrosion-resistant chromium-oxide layer.
Tooling Low Tolerance removes microns Lead days
Marking and inspection
Laser-mark, ultrasonic clean, then inspect the action, alignment, sharpness and finish.

Cost
What a micro forceps 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 a micro forceps at your volume, in your currency, are in the dossier.
