Engineering & Precision Manufacturing Capabilities
End-to-End Micro-Tubing Engineering Services — From Rapid Prototyping and Custom Machining to Cleanroom Assembly
LIJ Med Tube’s dedicated engineering team is guided by three core principles: Precision, Speed, and Partnership. Specializing in micro-tubing fabrication, custom component prototyping, and secondary processing, we collaborate closely with medical device innovators to bring advanced solutions to life—from initial drawing refinement and rapid prototyping to process validation and commercial manufacturing.
Engineering Support & DFM: We partner with your R&D teams to optimize wall thicknesses, tolerances, and geometric features, transforming raw concepts into manufacturable designs.
Rapid Prototyping: Powered by advanced CAD tools and micro-machining capabilities, we turn complex specifications into functional trial samples in days.
Scalable Production: Moving seamlessly from trial runs to validated, high-volume manufacturing while ensuring strict dimensional consistency and full material traceability.
Design Review
Based on the PDF drawings, STEP/CAD models, samples, and specifications provided by the customer, LIJ will conduct a comprehensive engineering review covering outer/inner diameters, wall thickness, tolerances, concentricity, materials, tip geometry, surface roughness, and manufacturability.
Prototype
The focus is on rapidly validating design concepts and basic functions; by producing prototypes in small batches, potential design flaws and manufacturing risks can be identified, providing a physical reference and a basis for testing to support subsequent optimization.
FAI / Inspection
Conduct comprehensive and rigorous dimensional and performance testing on the initial batch of trial-produced products and issue a First Article Inspection (FAI) report to ensure full compliance with drawing specifications and the customer’s quality requirements.
Design Optimization
Based on data feedback from prototype testing and first-article inspection, targeted fine-tuning is applied to the product structure, material selection, or tolerance settings to enhance performance, reduce production costs, and improve the yield rate.
Pilot Production
Conduct small-scale trial production simulating an actual mass-production environment, focusing on verifying the stability and repeatability of production processes and streamlining the supply chain, thereby laying the foundation for full-scale mass production.
Mass Production
Once manufacturing processes and quality controls have fully matured, full-scale production is launched; through rigorous in-process quality monitoring, the consistent quality and stable delivery of high-volume products are ensured.
