FEATURES

  • Foundational "Hard Power" – Building Customer Confidence Through Equipment Infrastructure

    1.1 Mold Machining Equipment

    Five-Axis High-Speed Machining Centers

     

    Ansix Tech's advanced 5-axis CNC machines achieve contour accuracies of ±0.002mm (2 microns) on complex curved surfaces. For three-ring syringe barrel production, this precision ensures that parting lines are smooth and burr-free.

     

    Value to Customer: This eliminates manual deburring operations (saving $0.08–0.12 per part in post-processing), prevents particulate contamination that could compromise sterility, and ensures the syringe loads smoothly into the injector head every time. When a medical device manufacturer receives a mold from Ansix, they are not receiving a tool that requires additional finishing—they are receiving a production-ready asset that goes straight into qualification.

     

    Wire EDM (Slow Wire Cutting)

     

    Capable of machining micro-features down to 0.03mm for thin-wall sections and narrow slots. This capability is critical for syringe components that require precise ejection pin holes and venting slots.

     

    Value to Customer: Allows precise feature machining without inducing thin-wall deformation—critical for maintaining uniform wall thickness and preventing stress cracking during high-pressure applications (up to 1,200 psi for contrast injection syringes). The customer avoids the costly scenario of scrapping an entire production run due to stress fractures in thin-wall sections.

     

    Sink EDM

     

    Complementing CNC milling by enabling precision machining in areas unreachable by conventional cutting tools, achieving surface finishes of Ra < 0.1μm.

     

    Value to Customer: Complex internal geometries can be manufactured without compromise, enabling innovative syringe designs that would otherwise be impossible or prohibitively expensive to produce.

    All-Servo Electric Drive Systems

     

    Servo-electric injection molding machines deliver stable repeatability with deviation ≤±0.1%, ensuring every molded syringe is identical to the previous one.

     

    Value to Customer: For annual volumes exceeding 500,000 syringes, per-part dimensional consistency eliminates sorting and rework costs. Ansix Tech has demonstrated cost reductions of up to 30% through precision process control and vertical integration. The customer hears: "Every part from every cavity, from every batch, will assemble perfectly—no sorting, no rework, no customer complaints."

     

    Tonnage-to-Product Matching

     

    Proper machine sizing reduces energy consumption by 12–18% and minimizes material waste from oversized runner systems.

     

    Value to Customer: Lower operating costs passed through in competitive pricing, and reduced environmental footprint—increasingly important for medical device manufacturers facing sustainability scrutiny.

     

  •  Inspection and Metrology

    Coordinate Measuring Machines (CMM)

     

    Every mold cavity undergoes full-dimensional inspection before shipment, with critical dimensional CPK maintained at ≥1.33. A CPK of 1.33 represents a Six Sigma-equivalent capability.

     

    Value to Customer: Production molds arrive ready for immediate qualification, eliminating the costly "teething" period that typically consumes weeks of production time and thousands of dollars in trial parts.

     

    Optical Imaging Systems

     

    Sub-micron resolution inspection for surface finish verification and detailed quality reporting.
