Expert precision metal stamping for surgical instruments. Shih Yeh manufactures tight-tolerance stainless steel components for medical devices with 36 years of expertise.
Precision Metal Fabrication of Stainless Steel Surgical Parts
Comprehensive fine stamping and bending services for surgical-grade components
Shih Yeh's expertise in metal stamping for surgical instruments delivers precise, high-tolerance parts tailored for complex medical applications like suture graspers. Each small stainless steel grasping jaw measures around 30mm by 6mm with a wire diameter under 0.6mm, requiring multiple challenging bends. We overcome material resilience, precisely maintaining strict tolerances. Grasping jaws are firmly riveted to an inner tube, ensuring stability and orientation. The inner and outer tubes are finely processed to enhance adhesion for insert molding, ensuring a secure, long-lasting assembly.
Precision Bending and Tolerance Control for Grasping Jaws
Our manufacturing process shapes small stainless steel grasping jaws with multiple precise bends. With a wire diameter below 0.6mm, these parts require careful handling, as even a slight deviation can affect the final dimensions. The stainless steel material exhibits rebound with each bend, which can affect dimensional accuracy. We counteract this material resilience, employing corrective measures that ensure the grasping jaws maintain exact dimensions and tight tolerances throughout production.
Riveting for Structural Integrity and Alignment
The grasping jaw assembly involves a specialized riveting technique that connects the grasping jaws to an inner fine tube. Beyond simply securing the parts, this method precisely controls the orientation of the jaws, ensuring consistent alignment. This process contributes to the stability and reliability of the part, essential for its performance in sensitive suture grasper applications.
Tube End Processing for Better Insert Molding Adhesion
To improve adhesion for insert molding, we meticulously process the ends of the inner and outer tubes. This includes flattening, turning, and sandblasting, ensuring a secure bond with the molded plastic. Additionally, these adjustments help control the orientation of the grasping jaws, enhancing the durability and alignment of the suture grasper device.
Manufacturing Capabilities and Application Scope
We have extensive experience in precision stainless steel stamping and forming, supporting surgical instrument components that require tight dimensional control and stable geometry. Stainless steel processing demands consistent forming conditions and precise process planning. Based on customer drawings, we develop suitable stamping solutions to maintain dimensional accuracy, structural consistency, and reliable quality for mass production.
These manufacturing capabilities are commonly applied to surgical instrument components such as blades, clamping parts, connecting plates, and fastening components. In addition, the same processes are well suited for precision electronic components, optical brackets, precision measuring tools, and other medical or industrial metal parts that require high dimensional accuracy and surface quality. Final process selection is evaluated according to product design and application requirements to ensure stable assembly performance and long-term reliability.
