FEATURES
Foundational Hard Power – The Equipment Backbone That Builds Customer Confidence
Before any discussion of design or process, it is essential to establish the technical foundation that makes precision manufacturing possible. Medical device customers are rightly concerned about consistency, repeatability, and quality assurance. Ansix Tech's equipment infrastructure provides the bedrock upon which all other capabilities rest.
1.1 Mold Machining Equipment: Precision That Translates to Product Reliability
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 1ml polycarbonate syringe barrel and cartridge syringe 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.
Slow-Speed Wire EDM (Wire Electrical Discharge Machining)
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 having to scrap an entire production run due to stress fractures in thin-wall sections.
Sink EDM with In-House Electrode Manufacturing
Complementing CNC milling by enabling precision machining in areas unreachable by conventional cutting tools, achieving surface finishes of Ra < 0.1μm. Ansix maintains its own electrode machining center and EDM workshop, ensuring that mold repairs and modifications can be completed without outsourcing.
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. For a medical device OEM facing a production deadline, the ability to perform a cavity modification within 24 hours rather than waiting weeks for an external vendor is invaluable. This reduces mold repair lead times, minimizing production downtime and inventory buffer requirements.
