  Hard Power Foundation – Equipment Infrastructure That Builds Customer Trust

  Before discussing what Ansix Tech can deliver, it is essential to understand the manufacturing infrastructure that guarantees precision, consistency, and reliability. Every equipment investment translates directly into customer benefits.

   

  1.1 Mold Manufacturing Equipment

  Five-Axis High-Speed Machining Centers – Capable of achieving 0.002mm precision on complex curved surfaces. This ensures that intake manifold parting lines are smooth and burr-free, eliminating the need for secondary finishing and saving customers 15–20% in post-processing costs. For engine intake manifolds with intricate aerodynamic channel geometries, this precision is critical for maintaining consistent airflow characteristics across the entire runner system.

   

  Slow Wire EDM (Electrical Discharge Machining) – Achieves 0.03μm precision for micro-pores and narrow slots. This capability enables the machining of ultra-fine features such as gas vents and micro-channels without thin-wall deformation, eliminating reject risk for critical sealing surfaces. Intake manifold molds often require precise venting channels to prevent air traps during filling—this equipment ensures those features are manufactured to specification.

   

  High-Precision Die-Sinking EDM – Multi-axis CNC-controlled with fine-finish capability. Complex cavity geometries with sharp internal corners can be fully machined, ensuring complete moldability of the manifold’s internal runner passages and filter structures.

   

  CNC Grinding Machines – Sub-micron surface finishing delivers mirror-like cavity surfaces. This reduces flow resistance, improves part release, and minimizes cycle time—directly translating to higher production throughput.

   

  Automated Machining Ratio – Ansix Tech maintains a 70% automated machining ratio, ensuring consistent quality across every mold component and reducing human error in critical manufacturing steps.

• Injection Molding Machine Fleet

  Ansix Tech’s injection molding machine lineup spans from 30 tons to 4,000 tons clamping force, covering the entire product size spectrum from small distribution ports to large mainline manifolds. This extensive range provides customers with a one-stop solution for all manifold sizes—eliminating the need to source from multiple suppliers.

   

  Every machine is equipped with full-servo electric drives, delivering stable repeatability at ±0.1% accuracy—meaning every single shot across the entire production run is dimensionally identical. Closed-loop pressure control with millisecond response time ensures consistent filling and packing, eliminating short shots and sink marks. Integrated automation including robotic part removal and conveyor systems enables lights-out production capability, reducing labor cost per part.

   

  1.3 Quality Inspection Equipment
