A Glimpse of some processes done to your instrument

At Rigor Instruments, precision is not just a goal — it’s our foundation. Our state-of-the-art manufacturing production process ensures surgical instruments that meet the strictest international standards of ISO 13485, CE marking, and FDA compliance. Here’s a detailed look at how we transform high-quality raw steel into world-class surgical tools.

 1. Raw Material Procurement & Inspection

• Purchasing Steel: Only medical-grade stainless steel (420, 440C, 316L) is procured from certified suppliers.

• Steel Inspection: Chemical composition and hardness are tested.

• Approval & Storage: Only approved steel is moved to the warehouse.

 2. Primary Processing

• Steel Shearing & Blank Cutting: Sheets are sheared and cut into blanks for the desired instrument.

• Hole Punching & Stamping: Identification marks and hinge holes are punched using CNC or press machines.

• Straightening: Blanks are straightened for dimensional accuracy.

 3. Forming & Forging

• Cold Forging & Annealing: Increases strength, followed by annealing to reduce brittleness.

• Hot Forging: Heats metal for complex shapes and durability.

• Outer & Ring Trimming: Removes excess metal for refined shaping.

 4. Pickling & First QA

• Pickling: Acid bath cleans oxidation and surface contaminants.

• QA Inspection 1: Instruments are checked for defects post-forging.

 5. Machining & Functional Settings

• Milling: Complex grooves and slots are machined.

• QA & QC Inspection 2: Tolerances and dimensions are checked.

• Pin Fitting & Functional Setting: Joint assembly and mechanical calibration.

• QA Inspection 3: Mechanical action is verified.

 6. Cleaning & Surface Preparation

• Boil Test & Passivation: Instruments are boiled and chemically passivated to enhance corrosion resistance.

• Final Polishing: Surfaces are mirror-finished for clinical use.

• Ultrasonic Cleaning: High-frequency vibration removes micro-particles.

• Sandblasting: Matte finish is applied where required.

 7. Surface Coating & Branding

• Gold Plating / Plasma Coating: Specialty finishes for ophthalmic or aesthetic tools.

• Final Setting & Buffing: Final touches on contours and shine.

• QA & QC Final Inspection: All instruments undergo a double-check process.

 8. Assembly & Labeling

• Grinding & Fitting: Sharpness and mechanical assembly.

• Lot Labeling: Each batch is labeled for traceability.

• UDI & Barcode Printing: Instruments are marked with unique device identifiers.

9. Packaging & Dispatch

• Packaging: Sterile or bulk packaging per customer specifications.

• Storage & Shipping: Secure warehousing until delivery.
