Cylindrical battery foam holder, rigid PU Foam Molding
Hard Power Infrastructure — The Foundation of Customer Trust
Precision Machining Equipment
Ansix Tech's equipment portfolio directly translates to superior part quality and reduced finishing costs. The company operates:
5-Axis High-Speed Machining Centers: Achieving machining accuracy of 0.002mm on complex curved surfaces. For cylindrical battery foam holders, this translates directly to parting lines that are smooth and flash-free, eliminating costly manual deflashing operations. Customer Value: No secondary trimming required; reduced labor costs; consistent cosmetic appearance.
Slow-Wire EDM (Electrical Discharge Machining): Capable of machining features as fine as 0.03mm in width for micro-pores and narrow slots. This is critical for thin-wall sections where deformation must be prevented. Customer Value: Precision thin-wall molding without distortion; consistent wall thickness across millions of cycles.
High-Precision Grinding and Polishing Equipment: Achieving surface roughness values as low as Ra 0.05μm for cavity and core surfaces. Customer Value: Optical clarity for transparent applications; zero adhesion defects; superior cosmetic finishes.
Multi-Stage Double-Taper Positioning Technology: For multi-cavity molds, maintaining perfect concentricity between core and cavity with eccentricity within 0.05mm. Customer Value: Eliminates dimensional "drift" that plagues lesser molds after extended production runs.
Injection Molding Machine Fleet
Ansix Tech operates 260 injection molding machines with clamping forces ranging from 30 tons to 4,000 tons, covering product sizes from micro-scale components under 1 gram to large automotive parts exceeding several kilograms.
Machine Brands: The fleet includes Japan's Fanuc, Sumitomo, Toshiba, Nissei, Engel, Germany's Arburg (primarily for liquid silicone injection molding), and China's Haitian and Victor Taichung Machinery.
All-Servo Electric Drives: All machines are equipped with all-servo electric drives, delivering stable process repeatability of ±0.1% variation from shot to shot. Customer Value: From the first shot to the millionth, every unit is identical — predictable quality, zero unexpected variation.
Quality Inspection Equipment
CMM (Coordinate Measuring Machines) and Optical Imaging Systems: Every mold undergoes a full dimensional report before leaving the shop, with Critical-to-Quality dimensions (CPK) maintained at ≥ 1.33. Customer Value: A CPK of 1.33 means the manufacturing process is capable of producing 99.9937% of features within specification — virtually eliminating the risk of receiving non-conforming tooling.
Part Two: Cylindrical Battery Foam Holder and Rigid PU Foam Molding — Product Introduction
Product Overview
Cylindrical battery foam holders are precision-molded components designed to house and protect sensitive lithium-ion battery cells. These components must provide:
Electrical insulation to prevent short circuits
Mechanical protection against vibration and impact
Thermal management to dissipate heat
Dimensional accuracy for proper cell alignment
Flame retardancy (UL94 V-0 rated) for safety compliance
Rigid PU (polyurethane) foam molding produces structural foam components with a solid skin layer over a microcellular foam core. This technology enables the production of high-quality, durable parts with improved strength-to-weight ratios.
