Clinical Expertise & Precision
Rooted in Medical Science, Crafted for Surgical Excellence
At DR MIRZA, quality assurance is not merely a final inspection—it is an end-to-end discipline integrated into every stage of manufacturing. Founded by Dr. Inam ul Haq Mirza, our operational framework bridges clinical necessity with advanced metallurgical craftsmanship in Sialkot, Pakistan.
Precision
Controlled In-Process QC
From drop forging to wire EDM cutting and CNC machining, our quality engineers monitor dimensional tolerances at each step to guarantee ergonomic balance and jaw alignment.
Continuous Audit
Continuous Quality Audit
Internal audits, third-party assessments, and customer feedback loops drive continuous improvement in metallurgical testing, heat treatment, and surface passivation.
Comprehensive Inspection Protocol
Our 6-Stage Quality Control Workflow
Every surgical instrument produced in our Sialkot facility undergoes rigorous testing to eliminate manufacturing variances before global distribution.
Raw Material Verification & Spectrometry
01We source certified medical-grade stainless steel (AISI 410, 420, 440, and 316L) as well as imported German stainless steel. Chemical composition and tensile strength are verified via spectrographic analysis before forging.
- Mill Test Certificates (MTC) verification
- Corrosion resistance pre-testing
Precision Drop Forging & CNC Machining
02Forging dies are calibrated to produce precise grain structure. Milling, box-lock fitting, ratchet cutting, and jaw serration machining follow exact master pattern specifications.
- Controlled thermal forging parameters
- Micrometer dimensional inspections
Vacuum Heat Treatment & Hardening
03Computer-controlled vacuum furnaces heat-treat instruments to achieve optimal Rockwell hardness (HRC 42-52 depending on tool classification), preventing jaw deformation and edge dulness.
- Rockwell scale hardness testing
- Stress relief and tempering cycles
Master Hand Finishing & Alignment
04Senior master craftsmen hand-set joints, balance tension in scissors and forceps, align teeth, and apply satin matte (anti-glare) or mirror finishes optimized for operating room lighting.
- Smooth ratchet ratchet engage check
- Zero-glare surface polishing
Chemical Passivation & Corrosion Testing
05Instruments pass nitric/citric acid passivation (ASTM A967 compliant) to build an inert chromium-oxide protective layer. Quality control conducts boil tests and copper sulfate testing to verify rust resistance.
- Boiling water corrosion test (ISO 7153-1)
- Autoclave steam endurance validation
Laser Marking, Final Inspection & Packing
06Each tool receives laser-engraved lot numbers, CE logos, and custom OEM branding for full traceability. Final optical microscope visual checks ensure zero burrs or surface defects before export packaging.
- 100% optical surface & joint check
- Barcoding & sterile pouching options
Institutional Standards
Sterilization, Traceability & OEM Assurance
Built for overseas distributors, hospital procurement groups, and private label partners who require total compliance certainty.
Sterilization
Cleaning & Bio-Burden Control
Multi-stage ultrasonic cleaning removes processing oils, polishing compounds, and particulate matter prior to final inspection, ensuring safe autoclave processing upon arrival.
Documentation
Full Lot Traceability
Every shipment includes Certificate of Conformance (CoC), material heat numbers, and inspection reports, simplifying customs compliance and institutional audit requirements.
OEM Quality
Custom Specification Verification
For custom manufacturing and OEM clients, first-article samples are produced and validated against technical blueprints prior to full-scale batch production.
