New energy vehicle headlight decorative strip mold

FEATURES

•  Hard Power Infrastructure—Building Trust Through Measurable Capabilities

  Transparency about manufacturing resources is the foundation of client confidence. Before discussing mold life or dimensional tolerances, Ansix Tech invites partners to examine the equipment backbone that enables consistent, high-precision optical molding.

   

  Precision Mold Processing Equipment

  New energy vehicle headlight decorative strips demand mirror-polished parting lines, flawless surface finishes, and sub-micron dimensional fidelity. Ansix Tech's mold machining portfolio is configured specifically for these requirements:

   

  5-Axis High-Speed Machining Centers deliver 0.002mm (2-micron) geometric accuracy on complex freeform surfaces, ensuring that mating lines on transparent components remain seamless and burr-free. This capability eliminates secondary manual polishing costs and prevents light leakage defects that arise from visible parting line misalignment. The automated machining ratio reaches 70%, significantly reducing human error and cycle times.

   

  Slow Wire EDM (Electrical Discharge Machining) enables the fabrication of 0.03mm micro-slots and narrow ribs without heat-affected zone distortion or burr formation. For thin-wall light guide features that resist conventional machining, wire EDM preserves wall integrity while achieving positional tolerances that sustain optical uniformity.

   

  CNC EDM and Precision Electrode Grinding Centers provide the fine finishing required for micro-optical surface patterns. Combined with in-house electrode manufacturing, this eliminates external vendor dependency and accelerates mold repair cycles to under 24 hours.

  Injection Molding Machine Fleet

  Headlight decorative strips range from short interior ambient lighting bars (150mm) to complex front grille signature strips exceeding 1200mm. Ansix Tech operates a comprehensive injection molding machine fleet spanning clamping forces from 30 tons to 4,000 tons, covering product sizes from miniature precision components under 10mm to large-format assemblies exceeding 1,000mm.

   

  All-Servo Electric Drive Systems deliver ±0.1% shot-to-shot repeatability. For light guide and decorative strip production, where melt temperature uniformity directly impacts clarity and stress birefringence, servo-electric precision ensures every mold cycle replicates the same optical performance standard.

   

  Liquid Temperature Control (LTC) Zone Management with integrated mold temperature controllers achieves cavity-to-cavity thermal balance within ±1°C. For thick-wall PC decorative strips (5mm–15mm typical wall thickness),±2°C temperature stability across core and cavity faces prevents differential shrinkage zones that cause rainbow banding, optical distortion, and visible surface defects.

   

  Real-Time Process Monitoring with closed-loop feedback automatically adjusts injection speed and pressure decay profiles based on cavity sensor inputs. For OEMs requiring PPAP (Production Part Approval Process) documentation, machine logs provide full parameter traceability.

   

  Quality Assurance and Metrology

  Every Ansix Tech mold undergoes full dimensional validation before leaving the facility:

   

  CMM (Coordinate Measuring Machine) inspection delivers complete geometric reports with feature-by-feature comparison against CAD baseline. Swedish Hexagon CMM equipment is employed for high-precision full-dimensional inspection.

   

  Optical 3D Scanners enable non-contact full-surface evaluation for freeform optics, particularly valuable for light guide components with draft angles and varying cross-section profiles.

   

  Critical Dimension Capability (CPK ≥ 1.33) is guaranteed on all customer-identified key characteristics, including sealing interfaces, mounting boss positions, and optical lens surface profiles. Automotive industry standards require a minimum Cpk of 1.33 for initial process capability studies.

   

  Hardness and Material Certification accompanies every mold delivery, ensuring full material traceability.
