Drug Delivery System Components CNC Machining for Medical Devices Industry

Yes, we coordinate comprehensive extractables and leachables (E&L) testing supporting FDA and international regulatory submissions for drug-device combination products. Working with certified analytical laboratories, we facilitate ISO 10993-12 sample preparation and extraction studies, ISO 10993-18 chemical characterization using GC-MS, LC-MS, and ICP-MS, and controlled extraction studies simulating worst-case drug contact conditions (temperature, duration, solvent systems). We provide material specifications and processing documentation required for E&L study design. Our quality system maintains material lot traceability linking components to specific E&L testing batches. This comprehensive approach supports safety assessments per FDA guidance on container-closure systems and satisfies regulatory requirements for pharmaceutical device combination products. 

Our drug delivery system components manufacturing employs ISO Class 7 cleanroom-adjacent facilities with controlled particulate levels, dedicated tooling used exclusively for pharmaceutical device components, and validated cleaning protocols preventing contamination. We use filtered coolants, implement material handling procedures in controlled environments, and conduct multi-stage ultrasonic cleaning followed by validated drying processes. Final inspection occurs in controlled environments under laminar flow hoods. Components are packaged in double-sealed cleanroom bags with particulate monitoring documentation. We provide certificates of cleanliness with particle count data, conduct bioburden testing when required, and maintain validated cleaning procedures supporting pharmaceutical manufacturing standards and regulatory requirements. 

Material selection depends on specific drug chemistry, pH, sterilization method, and regulatory pathway. 316L stainless steel provides excellent chemical inertness for most aqueous drug solutions and withstands steam sterilization. PEEK offers superior chemical resistance for aggressive formulations, organic solvents, and extreme pH ranges while maintaining dimensional stability. Cyclic olefin copolymer (COC) and cyclic olefin polymer (COP) provide pharmaceutical-grade performance with low extractables/leachables for prefilled syringes. Medical-grade polycarbonate works for structural components without drug contact. All materials include biocompatibility certifications (ISO 10993, USP Class VI) and we can coordinate extractables/leachables studies per ISO 10993-12/18 validating compatibility with your specific drug formulation.
 

Drug delivery system components affecting volumetric accuracy require micro-tolerances of ±0.0002″ to ±0.0005″ on dose-critical dimensions including internal bore diameters, plunger seal surfaces, and metering chamber volumes. For prefilled syringes and pump cylinders, we maintain bore diameter tolerances of ±0.0003″ ensuring volumetric accuracy within ±2-5% depending on nominal volume. Seal surface flatness must be within ±0.0002″ for reliable leak-free performance. Thread dimensions for luer connections meet ISO 594 standards with proper taper angle (6% ±0.1°). Our temperature-controlled manufacturing (±0.5°C), precision Swiss-style lathes with guide bushing support, and comprehensive CMM inspection with volumetric verification ensure dose accuracy consistency across production batches critical for therapeutic efficacy and regulatory compliance.
