Medical precision stamping parts represent a high‑barrier precision‑manufacturing segment, widely applied in minimally‑invasive surgery, implant devices and in‑vitro diagnostics. As one core minimally‑invasive surgical accessory, ophthalmic surgical blades are heavily adopted in phacoemulsification, corneal transplantation, glaucoma and other ophthalmic microsurgeries.

Despite their compact size, these components impose extreme manufacturing challenges. Ultra‑thin substrate and complex special‑shaped cutting edges demand uniform sharpness, burr‑free performance, micron‑level dimensional tolerance and corrosion resistance against body fluid. Ordinary general stamping workshops can hardly sustain stable mass output. It is a common industry pain point that prototypes pass validation yet mass‑production yield drops sharply.

Cooperating with qualified stamping manufacturer Jiaxing Aoke Hardware under IATF16949 quality management system, equipped with imported full‑set production & inspection hardware and rich track‑records of micro‑medical metal projects, Jiaxing Aoke Trading delivers end‑to‑end component services for global medical device OEM clients. Our scope covers requirement communication, DFM feasibility review, precision mold development, prototype sampling, low‑volume process validation and stable high‑volume production. Leveraging our core fastener business, we can also supply matching standard fasteners and custom hardware, delivering integrated sourcing support.

1.Available Types of Ophthalmic Surgical Blades

According to market requirements of overseas ophthalmic surgical instruments, we provide stamping blanks as below:

‑ 15° Sideport Knife: for auxiliary corneal puncture

‑ Slit Paracentesis Knife: for corneal side‑port creation

‑ Tunnel Knife / Crescent Knife: for corneal tunnel dissection

‑ Scleral Paracentesis Knife: for scleral access formation

Custom micro‑precision metal component development is available upon customer drawings or physical samples for special angles & contours.

2.Core Manufacturing Conditions & Quantified Benchmarks

• Mold R&D Team & Lead‑time Our partner plant employs 5 mold design engineers with minimum 7‑year experience in medical precision stamping, together with 15 senior mold technicians of 5‑15‑year working experience. The team covers structural design, CAE forming simulation, cavity machining, mold assembly and repeated trial‑run iteration. Lead‑time for medical‑grade progressive stamping mold is 22‑30 working days. Spring‑back compensation is pre‑implemented for ultra‑thin stainless‑steel sheets to mitigate subsequent mold‑modification risks.
• Raw‑material Control for Medical‑grade stainless steel stamping Only medical‑grade stainless steel is adopted. Incoming material inspection includes material certificate verification and metallographic sampling. Steel strips are screened to exclude scratches, inclusions and oxidation spots, eliminating root‑causes of edge chipping and surface corrosion. Different material grades are stored separately to avoid material mix‑up.
• Dimensional & Visual Specification for Micro‑precision metal component Tolerance of critical functional features reaches ±0.015 mm. Cutting edges shall be free of roll‑over, burr, notch and micro‑chipping. Straightness and profile of cutting edges are specially controlled. Surface roughness complies with requirements for microsurgical accessories to minimize tissue laceration risk in surgical procedures.
• Production & Inspection Infrastructure Production: Japan‑origin AMADA servo press for stable micro‑stamping; Japan Seibu wire‑EDM for high‑precision mold cavity machining. Inspection: Hexagon CMM coordinate measuring machine, KEYENCE 2.5D vision measuring system. Each batch follows first‑article approval, in‑process patrol inspection and last‑article comparison. 100% microscopic visual inspection is enforced for cutting edges, with complete batch traceability records kept.

3.Service Deliverables

• Pre‑project consultation: DFM assessment based on drawings / samples, output forming risks & optimization suggestions, identify manufacturing bottlenecks in advance to shorten project timeline and control mold‑revision cost.
• Mold development & validation: progressive mold fabrication, assembly and iterative trial runs.
• Tiered production: prototype sampling → low‑volume pilot run (500‑5000 pcs) for process tuning → continuous mass‑volume stamping.
• Post‑processing: precision deburring, ultrasonic cleaning, degreasing and custom debris‑free packaging.
• Extended sourcing service: coordinate other medical stamped parts, industrial fasteners and custom hardware for one‑project multi‑item demand, reducing customer multi‑vendor management burden.
