 Stamping Process in Surgical Instruments Manufacturing

Stamping is a key metalworking process in the surgical instrument industry that involves shaping or forming stainless steel sheets or blanks into precise components using dies and high-pressure presses. It’s used to create consistent shapes, markings, and detailed contours required for functionality and brand identity.


 Why Stamping is Important

 Shape Formation

  • Converts flat stainless steel into 3D instrument components (e.g. retractor blades, scissor handles)

  • Allows mass production with high precision and repeatability

 Part Number & Logo Marking

  • Used to stamp model numbers, sizes, “CE” marks, or “RIGOR INSTRUMENTS” branding directly on the tools

  • Ensures traceability, compliance, and professional finish

Structural Integrity

  • Precisely stamped parts have uniform thickness and dimensions

  • Reduces machining time and ensures fit accuracy during assembly


 Types of Stamping Used by Rigor Instruments

TypePurpose
BlankingCuts flat metal shapes for further processing
EmbossingAdds raised markings/logos on the tool surface
PiercingMakes precision holes and slots during forming
CoiningAdds fine text or numerical detail to surface
Bending/FormingShapes parts like clamps, scissors, retractors

Stamping in Rigor Instruments Workflow

  1. Die Design – Custom hardened steel dies created for each instrument model

  2. Steel Preparation – 420 or 440C stainless blanks cleaned and aligned

  3. High-Tonnage Presses – Mechanical or hydraulic presses apply up to 100+ tons force

  4. Marking – CE, LOT numbers, sizes, or RIGOR branding stamped

  5. Finishing – Deburring, polishing, and quality control

Risks of Poor Stamping

Misaligned stampsTools won’t fit or assemble properly
Weak embossed marksFades during sterilization or use
Burrs or rough edgesRisk of infection, discomfort, or contamination
