  Mold Processing Equipment

  Ansix Tech’s manufacturing capabilities begin with world-class precision equipment that directly translates into customer value:

   

  5-Axis High-Speed Machining Centers: Ansix Tech employs advanced 5-axis CNC machining systems capable of achieving positional accuracy of ±0.005 mm across complex curved surfaces. For through-type taillight molds that can exceed 1.2 meters in length, this level of precision is essential—any deviation in lens geometry produces visible distortion in the finished light bar. Customer Value: Flawless parting lines, no burrs, and optically perfect light guide surfaces that require no secondary finishing.

   

  Slow-Wire EDM (Electrical Discharge Machining): Capable of processing fine micro-holes and narrow slots as small as 0.03 mm, preventing thin-wall deformation in delicate optical features. Customer Value: The ability to create intricate lighting features that would be impossible with conventional machining, enabling cutting-edge design aesthetics.

   

  Wire-Cut and Sinker EDM Capabilities: Ansix Tech maintains in-house electrode machining centers and EDM workshops, meaning mold repairs and modifications are completed without leaving the facility—conventional weld repairs and insert replacements restored to production within 24 hours. Customer Value: Dramatically reduced downtime and maintenance lead times.

   

• Injection Molding Machine Fleet

  Ansix Tech operates a comprehensive range of injection molding machines with clamping forces spanning from 30 tons to 4,000 tons, covering everything from small precision components to full-width taillight assemblies exceeding 1.2 meters in length. Customer Value: One-stop manufacturing capability—no need to split production across multiple suppliers for different component sizes.

   

  All-Servo Electric Drive Systems: Every machine features servo-motor drives delivering stable repeatability precision of ±0.1%, ensuring every shot is consistent across millions of cycles. Customer Value: Batch-to-batch consistency eliminates dimensional variation issues that plague less capable manufacturers.

   

  Multi-Component Molding Capability: Ansix Tech supports two-color to multi-color (2K/3K) injection molding, combining different plastics and colors in one seamless production cycle. Customer Value: Elimination of post-painting and secondary assembly operations, reducing both cost and production time.

   

  1.3 Inspection and Quality Assurance Equipment

  Coordinate Measuring Machines (CMM): Every mold undergoes full dimensional inspection before shipment, with critical dimensions verified to CPK ≥ 1.33. Customer Value: Statistical proof of process capability, not just a promise—you receive data-backed assurance that your parts will meet specifications consistently.

   

  Optical Measurement Systems: High-precision optical inspection ensures surface quality meets the demanding requirements of transparent optical components. Customer Value: No hidden defects—every surface is verified against specifications.

   

  Full-Size Report Documentation: Each mold is delivered with a complete dimensional report comparing every critical feature against the CAD model. Customer Value: Complete traceability and documentation for your quality management system.

   

  II. Mold Manufacturing Core Competitiveness: Speaking Through Metrics

  2.1 Mold Life Expectancy
