Engineered for high-reproducibility medical tubing, specialized fluoropolymer catheter processing, and mission-critical fluid delivery setups.
A deep dive into polymer plasticization kinetics, thermal degradation management, melt pressure uniformity, and closed-loop dimensional stabilization.
Medical polyvinyl chloride (PVC) requires exact tailoring of plasticizers. We formulate with TOTM (Trioctyl Trimellitate), DOTP, and DINCH (Hexamoll), mitigating cytotoxic extraction risks and ensuring compliance with stringent REACH and California Prop 65 directives for neonatal and blood therapy circuits.
Processing PVC demands low shear friction to eliminate HCl off-gassing and burning. Our single-screw medical extruders utilize a 25:1 to 28:1 L/D ratio with chrome-plated, high-vanadium nitrided screw flights that preserve resin stability, eliminate gel points, and ensure laminar melt delivery to the crosshead die.
Achieving surgical tolerances down to ±0.01mm on ID/OD profiles necessitates synchronized closed-loop automation. Integrated dual-axis non-contact laser micrometers and ultrasonic wall thickness gauges continuously modulate haul-off velocity and vacuum calibration differential pressure in real time.

Medical device manufacturers navigating FDA 510(k), EU MDR 2017/745, and NMPA class certifications rely on our transparent, audit-ready validation document packages.
Every extrusion cell operates under comprehensive cleanroom protocols (Class 10,000 / ISO Class 7 and Class 100,000). Full bioburden control, airborne particle monitoring, HEPA filtration air balancing, and continuous surface disinfection guarantee ultra-clean products free from endotoxins and particulates.
We provide full-spectrum engineering dossiers including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ). Process validation verifies thermal windows, screw speed envelope limits, line velocity boundaries, and Cpk statistical capabilities exceeding 1.67.
Compound batches are pre-tested and certified for biocompatibility: ISO 10993-4 (Hemocompatibility), ISO 10993-5 (In Vitro Cytotoxicity), ISO 10993-10 (Sensitization/Irritation), and ISO 10993-11 (Systemic Toxicity). Drug compatibility reports verify zero adsorption of oncology therapies and insulin.
Combining the metallurgical and electromechanical excellence of Jiangsu's high-tech manufacturing cluster with rapid global fulfillment networks.
Based in Haian, Nantong, Jiangsu, our 16,000 m² campus operates at the epicenter of China's high-precision equipment corridor. With instant access to specialized vacuum metallurgical heat treatment, CNC micro-milling, and medical resin compounding vendors, we maintain complete supply chain sovereignty.
Western toolmakers frequently require 12 to 20 weeks for micro-extrusion die modifications. Our dedicated in-house EDM wire cutting, mirror polishing, and rheological simulation labs produce hardened tool steel crossheads in as few as 10 business days, drastically compressing device time-to-market.
Global Fortune 500 medical multinationals leverage our OEM/ODM facilities as a primary hedge against single-region supply bottlenecks. We deliver German and Swiss dimensional parity at 40% to 60% lower CapEx and OpEx, supported by multi-lingual field engineering teams across North America and Europe.
From neonatal intensive care units to cardiac operating suites, our custom extrusions meet stringent clinical fluidics requirements.
Ultra-clear, kink-resistant tubing engineered for micro-drip flow stability. Features mirror-smooth luminal surfaces to prevent protein adhesion, bubble accumulation, and micro-clotting during continuous drug delivery protocols.
