Tesla battery cell holder
FEATURES
Foundation of Hard Power — Building Customer Trust Through Equipment Infrastructure
Mold Manufacturing Equipment
Ansix's mold processing capabilities are anchored by five-axis high-speed machining centers that achieve positioning accuracy of ±0.002mm on complex 3D contours. This precision ensures that product parting lines remain smooth, consistent, and virtually invisible, eliminating the need for post-processing deburring operations. For delicate features such as retractable slide mechanisms, snap-fit tabs, and fine micro-holes, Ansix utilizes precision wire electrical discharge machining (EDM) capable of cutting channels as fine as 0.03mm without causing thin-wall deformation. This capability is critical for battery cell holders that require precise cell positioning and defined mechanical connections.
Customer Value Translation: Instead of stating "we have five-axis machining," Ansix communicates: "We eliminate the need for your secondary deburring operations, reducing your processing costs and lead times." The 0.002mm precision means parting lines are so smooth that no manual finishing is required on your assembly line.

- The mold manufacturing process and product material selection
Injection Molding Machine Fleet
Ansix's comprehensive machine park includes 260 injection molding machines with clamping forces ranging from 30 tons to 2,800 tons. The machine portfolio includes:
All-electric servo-driven machines from Fanuc, Sumitomo, Toshiba, and Nissei
Hydraulic and hybrid machines from Engel and Arburg
Domestic machines from Haitian and Victor Taichung Machinery
All machines are networked through a Manufacturing Execution System (MES) that locks critical forming parameters—temperature, pressure, injection speed, and cooling time—preventing unauthorized adjustments. Only qualified engineers can modify these settings, with every change logged and traceable.
Customer Value Translation: "Our all-electric servo machines deliver ±0.1% repeatability, meaning every single molded part from batch one to batch one million is dimensionally identical. You never have to worry about inconsistent parts disrupting your assembly line."
Quality Inspection and Metrology Equipment
Ansix's quality laboratory is equipped with coordinate measuring machines (CMMs) and optical imaging systems capable of sub-micron resolution. Every mold undergoes full dimensional inspection before shipment, with critical dimensions validated to CPK ≥ 1.33—the industry gold standard for process capability.
What CPK ≥ 1.33 Means for You: A Cpk of 1.33 provides a four-sigma buffer that statistically limits defects to approximately 63 parts per million. Most automotive OEMs require Cpk ≥ 1.33 for initial process studies, and critical dimensions often require Cpk ≥ 1.67. Ansix not only meets but exceeds these requirements.
Customer Value Translation: "We don't just say we make quality parts—we prove it with data. Every critical dimension on your battery cell holder comes with a CPK report showing you exactly how capable our process is. No guesswork, no surprises."

Through advanced Moldflow CAE simulations, Ansix predicts melt front behavior, weld line locations, and trapped air positions before any steel is cut. This enables:
Optimized gate location and quantity
Balanced cavity filling without overpacking
Elimination of sink marks, weld lines, and gas traps
Customer Value Translation: "We find your defects in the computer, not in your parts. By simulating the entire injection process virtually, we eliminate the need for expensive mold modifications after steel is cut—saving you time and money."

Simple Molds 10 days —
Medium Complexity 25-45 days 20 days with parallel validation
High Complexity 45-60 days Custom schedule
Critical Note: Expedited delivery never compromises validation—all verification steps remain intact.
Part III: Injection Molding — Process Control to Eliminate Quality Anxiety
What Customers Fear Most
Shrinkage and sink marks
Flash and burrs requiring secondary operations
Dimensional drift between batches
Batch-to-batch color variation
Long repair cycles when problems occur
Process Standardization and Control
All molding machines are connected through MES software that locks and records every parameter—temperature, pressure, injection speed, cooling time. This provides:
Full traceability — every part can be traced back to specific machine, operator, and parameter set
Unauthorized change prevention — only engineers can modify settings
Data-driven optimization — historical data enables continuous improvement
Customer Value Translation: "Your parts are made the same way every single time. Not 'almost the same'—identical. Our MES system ensures that the process that made the first good part is the same process that makes the millionth part."
Dimensional Stability Control
Ansix integrates thermal oil circulators that maintain cavity-to-core temperature differentials within ±2°C, dramatically reducing part warpage, distortion, and residual stress. For battery cell holder components, continuous production across three separate batches demonstrates dimensional fluctuation of less than ±0.02mm on critical mounting features.
Industry Context: A single battery module frame mold might have 80+ lifters, 12 core pulls, and require cooling channel layouts that maintain uniform wall temperature within 2°C across a part that is 400mm long. Ansix has mastered this complexity.
Customer Value Translation: "When you assemble 100 battery packs, every cell holder fits exactly the same. No shimming, no forcing, no rework. Your assembly line runs smoothly because our parts are consistent."
Surface Finish and Appearance Quality
Requirement Ansix Capability
Transparent Parts No bubbles, no flow marks
