Hard Power Infrastructure — Building Customer Trust Through Equipment Foundation
Before discussing process sophistication, customers need to trust the physical assets that make precision possible. Ansix Tech has strategically invested in equipment specifically selected for automotive battery component molding applications.
- Precision Mold Machining Equipment
Five-Axis High-Speed Machining Centers: Ansix Tech operates multiple five-axis high-speed machining centers capable of achieving 0.002mm machining accuracy. For the Chery Battery Mounting Bracket, this means complex curved surfaces and critical parting lines are machined with extreme fidelity. Customer Value: Seamless parting lines translate to no flash, no secondary deburring, and no post-molding manual trimming—eliminating one of the most common hidden costs in Automotive Molding.
Slow-Speed Wire Electrical Discharge Machines (EDM): With cutting precision of ±0.003mm, capable of generating 0.03mm–0.10mm diameter micro-pins and narrow slots with sub-0.01mm positional accuracy. Customer Value: Enables production of fine features required for complex bracket geometries; prevents thin-wall deformation during ejection; reduces rework rates.
CNC Electrical Discharge Machining (Sinker EDM): ±0.005mm cavity depth control with electrode wear compensation algorithms. Customer Value: Produces sharp internal corners and deep rib structures essential for bracket rigidity; ensures uniform wall thickness distribution.
High-Precision Surface/Profile Grinding: Flatness ≤0.003mm per 300mm length; surface finish Ra≤0.1μm on critical parting surfaces. Customer Value: Guarantees perfect mold closure under clamp pressure; eliminates flash along the entire bracket perimeter.
All five-axis CNC machines are equipped with Renishaw probing systems for in-process part verification, reducing setup errors and ensuring that every electrode and cavity block is machined to print before assembly.
- Injection Molding Machine Fleet
Ansix Tech operates 260 injection molding machines with clamp forces ranging from 30 tons to 2,800 tons, strategically deployed across four manufacturing campuses. This breadth covers the entire spectrum of automotive component production—from small precision components to large structural parts.
Key Machine Specifications:
Specification Detail Customer Value
Clamp Force Range 30–2,800 tons Covers bracket sizes from small cell holders to full battery mounting frames
Drive Technology All-servomotor electric and hybrid servo-hydraulic systems ±0.1% shot-to-shot weight repeatability; every bracket in a million-part run is dimensionally identical
Injection Pressure Up to 2,500 bar Sufficient for high-viscosity engineering plastics including glass-filled nylons and high-performance blends
Screw Design General-purpose and barrier-type screws with wear-resistant coatings Handles glass-filled materials without material degradation or screw wear
Premium Machine Brands: Japan's Fanuc, Sumitomo, Toshiba, Nissei, Engel; Germany's Arburg (specializing in liquid silicone with two-component capabilities); domestic machines from Haitian and Victor Taichung Machinery.
Every machine is integrated into a centralized MES (Manufacturing Execution System), with molding parameters—temperature, pressure, speed, hold time—locked to engineer-authorization only. This prevents unauthorized floor adjustments that could drift parts out of specification.
- Measurement and Validation Equipment
Coordinate Measuring Machines (CMMs): Capable of sub-micron resolution, generating full dimensional reports for every mold before shipment. Customer Value: Every mold is validated against print before production begins; critical dimensions are verified with CPK ≥1.33.
Optical Imaging Systems: Sub-micron resolution for visual inspection and dimensional verification.
