Medical & Diagnostic Product Applications
Medical applications demand uncompromising part-to-part consistency, biocompatible material selection, and clean surfaces free of particulate or grease contamination.
Key Medical Product Verticals
- In-Vitro Diagnostic (IVD) Cassettes: Point-of-care rapid testing cartridges featuring microfluidic channels, reagent wells, and ultrasonic weld joints.
- Syringes & Fluid Delivery: High-cavitation (64-cavity and 128-cavity) barrels, plungers, and IV needle hubs molded in medical-grade PP and COP.
- Surgical Instrument Handles: Rigid structural PEEK and glass-filled polyphenylsulfone (PPSU) components designed for autoclave sterilization.
- Respiratory & Anesthesia: LSR elastomeric diaphragms, non-rebreather valves, and transparent optical polycarbonate face masks.
Microfluidic Channel Tooling & Optical Precision
Sub-Micron Machining & Mirror Polish
Diagnostic lab-on-a-chip cartridges require fluid capillary channels measured in microns. Machining these features requires nano-finish high-speed CNC milling spindles (operating at 40,000 RPM) and diamond fly-cutting.
Optical detection windows are hand-lapped with diamond paste to SPI A1 optical clarity, ensuring distortion-free laser fluorescence reading during diagnostic testing. Learn more on our tooling capabilities page.
Class 100k Cleanroom Molding & Assembly
Controlled Production Environment
Our medical manufacturing suites operate under ISO Class 8 (Class 100,000) air cleanliness standards. Key features include:
- All-Electric Japanese Presses: Sumitomo and Fanuc presses eliminate hydraulic oil mist and airborne particulate risks.
- Positive Air Pressure: Multi-stage HEPA filtration prevents external dust infiltration during personnel entry.
- Closed-Loop Resin Feeding: Stainless steel vacuum conveyors deliver resin directly from desiccant dryers into machine hoppers.
Comprehensive IQ / OQ / PQ Validation
Bringing a medical device to market requires exhaustive documentation proving the injection molding process is stable and repeatable.
| Validation Phase | Core Objectives | Documentation Deliverables |
|---|---|---|
| Installation Qualification (IQ) | Verify equipment calibration, utility hookups, and tool design specs | Calibration logs, tool drawing BOM, steel mill certs |
| Operational Qualification (OQ) | Define upper and lower operating boundaries via Design of Experiments (DOE) | DOE parameter matrix, gate freeze studies, viscosity curves |
| Performance Qualification (PQ) | Demonstrate long-term process capability across 3 full production runs | Cpk ≥ 1.67 statistical analysis, bioburden testing |
