Superior Airtightness: Precision-molded sealing structures with ±0.02mm dimensional tolerance ensure leak-free gas transmission, critical for maintaining stable oxygen/air pressure in breathing circuits.
Medical-Grade Biocompatibility: Crafted from USP Class VI & ISO 10993-certified plastics, our connectors are non-toxic, non-irritating, and compatible with human respiratory tissues, eliminating risks of adverse reactions.
Sterilization Compatibility: Resistant to multiple sterilization methods (gamma irradiation, EtO gas, autoclaving), maintaining structural integrity and performance after 50+ sterilization cycles.
Customized Fit: Fully tailored to your breathing machine’s interface design, including size, shape, connection type (luer lock, snap-fit, threaded), and port configurations.
Durable Construction: Impact-resistant and wear-resistant materials prevent cracking or deformation, even in high-frequency clinical use (e.g., emergency departments, ICUs).
Superior Airtightness: Precision-molded sealing structures with ±0.02mm dimensional tolerance ensure leak-free gas transmission, critical for maintaining stable oxygen/air pressure in breathing circuits and preventing life-threatening gas leakage.

| Material Type | Key Properties | Application Scenarios |
|---|---|---|
| Medical-Grade PP (Polypropylene) | Lightweight, excellent chemical resistance, compatible with EtO/gamma sterilization, cost-effective | Disposable breathing circuit connectors, general-purpose ventilator interfaces |
| Medical-Grade PC (Polycarbonate) | High impact strength, heat-resistant (up to 120°C), transparent for visual inspection, reusable | Reusable ventilator connectors, anesthesia machine gas delivery ports |
| Medical-Grade TPE (Thermoplastic Elastomer) | Soft, flexible, excellent sealing performance, biocompatible, compatible with skin contact | Connector gaskets, sealing rings, flexible interface adapters |
| Medical-Grade ABS | High rigidity, dimensional stability, good surface finish, suitable for complex structures | Multi-port breathing machine connectors, integrated connector assemblies |
High-Precision Cavity Machining: Utilizing 5-axis CNC machining and diamond turning, the mold cavity and core achieve Ra ≤ 0.01μm surface finish. This ensures smooth connector surfaces that avoid dust accumulation, facilitate cleaning, and prevent irritation to respiratory tissues.
Sealing Structure Optimization: Mold-integrated sealing grooves with precise dimensional control (±0.01mm) ensure a tight fit between the connector and breathing circuit tubes. The optimized groove design enhances sealing performance and extends the service life of the connector.
Undercut Handling: For connectors with complex structures (e.g., luer lock threads, snap-fit features), we use hydraulic slide mechanisms in the mold. This ensures easy demolding without damaging the product, maintaining thread integrity and structural stability of undercut features.
Conformal Cooling Channels: 3D-printed cooling channels that follow the connector’s contour ensure uniform mold temperature (±1°C). This reduces internal stress and prevents warpage, which is critical for maintaining dimensional stability and airtightness of the connector.
Mold Durability: Molds are made of high-quality medical-grade tool steel (S136, H13) with corrosion-resistant PVD coating, ensuring mold life of 1–3 million cycles. This supports high-volume production while maintaining consistent product quality.
| Parameter | Specification | Purpose |
| Melt Temperature | 260–280°C | Ensures uniform melting of PC material for smooth flow into complex mold cavities, avoiding flow marks and voids. |
| Mold Temperature | 80–100°C | Reduces internal stress in the product, preventing post-mold cracking and warpage, which is critical for maintaining dimensional stability. |
| Injection Pressure | 900–1100 bar | Fills thin-walled sections (e.g., sealing edges) without voids or defects, ensuring complete mold filling and structural integrity. |
| Hold Pressure | 50–60% of Injection Pressure | Eliminates surface sink marks and ensures dimensional accuracy by compensating for material shrinkage during cooling. |
| Cooling Time | 30–40s | Fully cures the product to avoid deformation during demolding, ensuring the connector maintains its shape and sealing performance. |
Airtightness Test: Conducted using pressure decay method (test pressure: 0.5–1.0 MPa, holding time: ≥30s) to ensure no gas leakage, meeting the airtightness requirements of ISO 80601-2-12.
Dimensional Inspection: Using Coordinate Measuring Machine (CMM) with ±0.001mm precision to verify all critical dimensions, ensuring compatibility with breathing machine interfaces.
Biocompatibility Verification: Regular batch sampling for cytotoxicity, skin irritation, and sensitization tests in accredited third-party laboratories to confirm compliance with medical safety standards.
Sterilization Validation: For sterilizable connectors, we perform sterilization validation tests (gamma irradiation/EtO gas) to ensure structural integrity and performance stability after the specified number of sterilization cycles.
