CA Material Doll Injection Molding Mold

FEATURES

• Hardware Capabilities – The Foundation of Customer Trust

  Mold Processing Equipment

  Ansix's manufacturing floor is equipped with state-of-the-art machinery that forms the bedrock of precision manufacturing. The company operates five-axis high-speed machining centers capable of machining complex curved surfaces with ±0.002mm precision. This capability ensures that part line transitions remain smooth and free from burrs—a critical aesthetic requirement for doll products where surface quality directly impacts market appeal.

   

  The workshop features slow wire EDM (Electrical Discharge Machining) systems that can machine micro-holes and narrow slots as small as 0.03mm. For doll mold applications, this precision prevents thin-wall deformation and enables the creation of intricate facial features, hairline details, and delicate appendages that define high-quality doll products.

   

  Additional equipment includes precision EDM sinker machines achieving ±0.005mm precision for complex mold cores and cavities. The integration of CNC machining centers, EDM, and wire cutting capabilities means that mold返修 (repairs and modifications) can be completed in-house without outsourcing—typically within 24 hours for standard repairs.

   

  Customer Value Translation: “Our five-axis machining centers achieve 0.002mm precision—equivalent to 1/50th the thickness of a human hair. This means your doll's facial contours, joint interfaces, and assembly features will be flawless from the first shot, eliminating costly post-processing and rework.”

The machines feature all-servo electric drives delivering stable repeatability accuracy of ±0.1% , ensuring that every shot in mass production maintains consistent quality.

   

  Customer Value Translation: “Our servo-driven machines span from 30 tons for fine facial features to 4,000 tons for full doll bodies. The ±0.1% repeatability means part #1 and part #100,000 are virtually identical—your assembly lines never see dimensional drift.”

   

  Quality Inspection Equipment

  Ansix operates a fully equipped metrology laboratory featuring Coordinate Measuring Machines (CMM) and optical vision inspection systems. Every mold undergoes a comprehensive dimensional inspection before shipment, with full-dimension reports provided to customers. Critical dimensions are validated with Cpk (Process Capability Index) ≥ 1.33, demonstrating that the manufacturing process is statistically capable of meeting specifications.

   

  Customer Value Translation: “Every mold we ship comes with a full dimensional report and Cpk data. A Cpk of 1.33 means our process uses only 75% of your tolerance band—giving you a safety margin that protects against unexpected variations.”
