From forge to theatre

Manufacturing

Eight stages, from bar stock to a marked, inspected and packed instrument. Every instrument is traceable from its material certificate to its carton.

Manufacturing

Stage by stage.

Eight stages, from bar stock to a marked, inspected and packed instrument.

Die forging

Stage 01

Die forging

Bar stock of surgical stainless steel is heated to forging temperature and struck in closed dies, so the grain follows the shape of the instrument.

Trimming & annealing

Stage 02

Trimming & annealing

Flash is trimmed from every blank and the steel is annealed soft so it can be machined without stress cracks.

Milling & box-lock fitting

Stage 03

Milling & box-lock fitting

Jaws, serrations, ratchets and box locks are milled, then the two halves are hand-fitted so the joint moves smoothly with no play.

Hardening & tempering

Stage 04

Hardening & tempering

Instruments are hardened and tempered in controlled furnaces to the hardness each pattern needs — hard edges, springy handles.

Grinding & setting

Stage 05

Grinding & setting

Blades are ground and set by hand. Scissors are adjusted until they cut cleanly to the tip; forceps until the jaws meet evenly.

Polishing & finishing

Stage 06

Polishing & finishing

Satin, mirror or black-coated finishes are applied on buffing lines and glass-bead cabinets. Tungsten carbide inserts are brazed and ground.

Passivation & laser marking

Stage 07

Passivation & laser marking

Instruments are cleaned and chemically passivated to restore the chromium-oxide layer, then laser-marked with code, lot and your brand.

Inspection & packing

Stage 08

Inspection & packing

Every piece is checked under magnification for alignment, ratchet engagement, cutting and finish, then packed in pouches, boxes or cases.
