Features
Tight Tolerance Replication: Servo-electric injection units deliver closed-loop cavity pressure control for stable part dimensions across multi-cavity tools.
Traceability Integration: Laser-etched data matrices or cavity-number identification molded directly into components for full lot-to-resin batch traceability.
Cleanroom Post-Processing: Automated part removal, gate trimming, and inner-packaging executed directly inside controlled environments to eliminate particulate contamination.
Validation Readiness: Comprehensive IQ/OQ/PQ documentation packages supported by automated vision inspection data and CMM reports.
Materials & Manufacturing
Medical-Grade Resins Processed
Amorphous Polymers: PC (Polycarbonate), PSU (Polysulfone), PES, COP/COC (Cyclic Olefin Polymer/Copolymer for optical clarity and low birefringence).
Semi-Crystalline Polymers: PP (Polypropylene), HDPE/LDPE, PEEK, POM (Delrin), PA (Nylon).
Elastomers: TPE, TPU, LSR (Liquid Silicone Rubber) for soft-touch seals and diaphragms.
Manufacturing Infrastructure
Tooling Construction: In-house precision tool room equipped with high-speed CNC, wire EDM, and mirror EDM to maintain mold life exceeding 1,000,000 cycles.
Molding Machines: Fanuc and Arburg electric injection presses featuring dry-air resin drying systems and closed-loop water temperature controllers to prevent thermal degradation.
Applications
Diagnostic Consumables: Microfluidic chips, reagent cartridges, and sample collection vials requiring optical clarity and zero extractables.
Surgical Instruments: Ergonomic reusable and disposable device housings, trocars, and endoscope components.
Fluid Management: Manifolds, connector valves, luer fittings, and drip chambers requiring leak-free sealing under pressure.
Drug Delivery Devices: Pen injector bodies, inhaler internal actuators, and auto-injector structural shells.
Customization
Tooling Options: Prototype aluminum molds (quick-turn, 1 to 5 cavities) and production-grade hardened steel molds (multi-cavity with hot runner systems).
Secondary Operations: Ultrasonic welding, pad printing, laser marking, and sub-assembly integration.
Packaging Solutions: Cleanroom double-bagging, custom thermoformed tray packaging, and custom labeling per customer specifications.
QC & Quality Assurance
Inspection Equipment: Keyence optical comparators, 3D CMM, automated multi-axis vision measuring systems, and laser roughness testers.
Process Control: Real-time cavity pressure monitoring and automated reject sorting for out-of-spec shots.
Certifications: ISO 13485:2016 certified facility; cleanroom environment verified regularly via particle counters and microbial monitoring.
Documentation: Material Test Reports (MTR), Certificate of Analysis (CoA), and full dimensional inspection reports supplied with every production lot.
FAQ
Q: What is your standard lead time for medical mold tooling and initial samples?
A: Tooling fabrication typically takes 4 to 6 weeks depending on part complexity. T1 samples and initial dimensional reports are delivered within 7 business days following mold completion.
Q: Do you provide full IQ/OQ/PQ validation support?
A: Yes. We supply complete validation protocol templates and execution data, including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) support for regulated devices.
Q: How do you handle medical-grade resin storage and lot control?
A: All medical resins are stored in a temperature- and humidity-controlled warehouse. Material lot numbers are recorded at the resin hopper and tracked through packaging labels to ensure strict FIFO and traceability.
Q: Can you accommodate multi-material or insert molding?
A: Yes. We utilize multi-shot injection presses and vertical rotary tables for plastic-to-metal inserts and dual-hardness (rigid body + soft seal TPE) configurations.
