Main Application Scenarios of Medical Plastic Injection Molding

The mainstream applications of medical plastic injection molding cover the entire medical industry chain. Different scenarios have significantly different requirements for material precision and biosafety, which can be broadly categorized into six main types:

1. Disposable Medical Consumables Scenarios

Core Share: This is currently the largest application area, accounting for 52% of the total medical injection molding market, with injection-molded parts making up over 85% of all consumable components.

Typical Products: Syringes, infusion sets, various catheter connectors, blood collection devices, infusion loops, etc., suitable for high-volume, low-cost mass production.

Material Selection: Primarily polypropylene and polycarbonate, meeting the basic requirements of chemical resistance and rapid sterilization.

2. Diagnostic and Monitoring Equipment Scenarios

Core Positioning: Providing structural and functional support for high-precision testing equipment, ensuring the stability of test data.

Typical Products: Shells and buttons for blood glucose meters and blood pressure monitors; precision components for PCR testing instruments and blood cell analyzers; test kit shells.

Process Requirements: Mostly employing micro-injection molding processes, with tolerances of key components controlled at ±0.01 mm to avoid affecting testing accuracy.

3. Minimally Invasive Surgery and Implantable Device Scenarios

Core Positioning: High-end scenarios with the highest requirements for biocompatibility and long-term stability, directly related to clinical safety.

Typical Products: Laparoscopic surgical instrument handles, vascular interventional catheters, artificial joints, pacemaker housings, etc.

Material Selection: Primarily uses special engineering plastics such as polyetheretherketone (PEEK). Some implantable products require production under ISO Class 5 laminar flow hoods.

4. Drug Delivery System Scenarios

Core Positioning: Ensuring precise drug dosage control while improving patient convenience.

Typical Products: Precision gears, valves, and housings for insulin pens, needle-free injectors, inhalers, and wearable infusion pumps.

Process Characteristics: Extensive use of two-color injection molding and insert injection molding technologies, balancing component structural strength and user-friendly grip.

5. Medical Aseptic Packaging Scenarios

Core Positioning: Maintaining the aseptic state of medical products, possessing reliable sealing and barrier properties.

Typical Products: Pharmaceutical blister packs, reagent bottle caps, aseptic packaging boxes, medical injection molded trays/boxes/caps, etc.

Performance Requirements: Must meet the requirements of resistance to repeated sterilization and non-deformation during stacking; some products are compatible with EO sterilization processes.

6. Public Medical Auxiliary Facilities Scenarios

Core Positioning: Practical injection molded products adapted to the special environment of hospitals, reducing the risk of cross-infection.

Typical Products: Contactless automatic opening and closing medical waste bins, surgical instrument trays, etc.

Material Selection: Primarily uses high-density polyethylene to achieve impact resistance, corrosion resistance, and easy sterilization.
