A needle holder is primarily made by Impression-die Forging. Impression-die (closed-die) forging squeezes hot metal into a shaped die cavity so the grain follows the form. It gives high strength and good repeatability. Below is the full route to make a needle holder, 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 needle holder is made
The usual route, raw material to finished part. The amber step is where the needle holder gets its basic shape.
Material
Cut martensitic stainless bar (420 or 410 grade) sized for the needle holder.
Die forging
Heat and drop-forge the blank (both halves of the instrument), so the grain follows the form and gives the strength.
Tooling High (dies) Tolerance ±0.25 to 1mm Lead 8 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 needle holder.
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.
