33140 Lithium Battery Holder, Lithium Iron Phosphate Battery Cell Holder
FEATURES
Hard Power Infrastructure — Building Customer Trust Through Equipment Excellence
Mold Manufacturing Equipment
Ansix's mold shop is equipped with world-class machining centers that directly translate into product quality for customers:
Five-axis high-speed machining centers capable of machining complex curved surfaces with 0.002mm precision. For 33140 battery holders, this means smooth, burr-free parting lines—eliminating secondary deburring operations and ensuring clean assembly interfaces between battery cells and holders.
Slow wire EDM (Electrical Discharge Machining) capable of producing 0.03mm micro-holes and narrow slots. For battery holder designs requiring precision locating features or ventilation slots, this capability prevents thin-wall deformation that could compromise cell retention force.
EDM (Electrical Discharge Machining) workshops and electrode processing centers enable rapid mold repairs—routine welding and insert replacements can be restored within 24 hours, minimizing production downtime.

- The mold manufacturing process and product material selection
Injection Molding Machine Fleet
Ansix operates 260 injection molding machines from leading global brands including Japan's Fanuc, Sumitomo, Toshiba, Nissei, Engel, and Germany's Arburg. The tonnage range from 30 tons to 2,800 tons covers everything from small precision components to large-format battery holder arrays.
All-servo motor drives deliver stable repeatability accuracy of ±0.1% —meaning every shot is consistent, batch after batch. For customers, this translates to predictable assembly line performance and zero unexpected dimensional drift.
Inspection and Quality Assurance Equipment
CMM (Coordinate Measuring Machines) and optical imaging inspection systems ensure every mold undergoes full dimensional reporting before shipment.
Critical dimensions are validated with CPK ≥ 1.33—a statistical measure that guarantees process capability far exceeding industry standards. For customers, this means fewer field failures, lower warranty costs, and consistent product quality.

Material Certification Full material certificates and heat treatment curves provided Complete traceability — customers can verify material authenticity and热处理 quality
Structural Warranty 3-year mold structure warranty (excluding normal wear parts) Peace of mind — predictable tooling lifecycle costs
Achievable Tolerances
General structural parts: ±0.05mm — suitable for most battery holder mounting features
Precision gears/medical-grade components: ±0.005mm — for applications requiring ultra-precise cell alignment
Customer Value: Tight tolerances mean batteries seat perfectly every time, eliminating assembly rejects and rework costs.
Mold Types and Capabilities
Ansix offers a comprehensive range of mold technologies:
Hot runner systems — reduce material waste and shorten cycle times
Stack molds — double production efficiency from a single machine
Two-shot/multi-material molds — enable complex designs with integrated features
High-gloss molds (Ra < 0.05μm) — suitable for transparent or cosmetic-grade components
Gate and Runner System Design
Through mold flow analysis, Ansix pre-identifies weld line and gas trap locations, optimizing gate quantity and positions to ensure balanced filling.
Customer Value: Balanced filling means no short shots, no sinks, no warpage — every part comes out geometrically correct, reducing scrap rates and rework labor.
Mold Delivery Standards
Mold Complexity Standard Lead Time Expedited Option
Simple molds 10 days —
Medium-complexity 25-45 days 20 days (with validation steps preserved)
Customer Value: Predictable timelines mean customers can plan production schedules with confidence — no costly delays in product launch.
Part III: Injection Molding Process Control — Eliminating Quality Anxiety
What Customers Fear — And How Ansix Eliminates It
Customer Concern Ansix's Solution Value Delivered
Sink marks Optimized packing pressure and cooling profiles Zero visual defects — no need for secondary filling or rejection
Flash (burrs) 0.005mm fit precision on parting surfaces; self-locking clamp force compensation; flash controlled within 0.03mm Eliminates manual deburring — saves labor cost and production time
Dimensional instability Ultrasonic wall thickness sensors; real-time pressure compensation; in-mold temperature/pressure sensors with closed-loop control Parts stay within spec — no assembly line stoppages
Batch-to-batch color variation All machines networked; parameters (temperature, pressure, speed, time) locked in MES; only engineer-authorized adjustments Color consistency — professional appearance, no customer complaints
Process Standardization
All machines are networked and monitored. Molding parameters (temperature, pressure, speed, time) are locked in the MES system—only authorized engineers can make adjustments. First-article and last-article inspections are performed for every batch.
Customer Value: This eliminates the "fingerprint" variability of manual machine operation. Every batch is identical to the last.
Dimensional Stability Control
Molds are equipped with zone-controlled temperature regulators, maintaining core and cavity temperature differentials within 2°C to minimize warpage and deformation.
Quantified assurance: For similar holder products, three batches produced consecutively over one week showed key hole spacing variation ≤ 0.02mm.
Customer Value: This level of stability means automated assembly lines run without interruption — no jams, no misalignments, no production stoppages.
Surface Finish and Aesthetic Grades
Ansix can achieve:
Transparent parts: No bubbles, no flow marks
Plating-ready parts: No gas marks
High-gloss parts: Surface roughness Ra ≤ 0.2μm
Printing/painting applications: Deformation compensation预留; registration accuracy ≤ ±0.1mm
Specialty Material Capabilities
Ansix has extensive production experience with a wide range of engineered plastics:
Material Key Properties Application in Battery Holders
PC/ABS Impact resistance, dimensional stability General-purpose battery holders

Flame Retardancy: UL94 V-0 rated materials available for safety-critical applications.
Weathering: UV testing validated for 3,000 hours without discoloration.
Customer Value: One partner, all material needs covered — no need to source from multiple suppliers. Reduced supply chain complexity, lower procurement costs.
Shrinkage and Warpage Control
For battery holder applications, shrinkage rates typically range from 0.3–0.7%. Ansix's mold design compensates for material-specific shrinkage, ensuring final parts meet dimensional specifications without secondary machining.
Part IV: Full-Process Services — Reducing Customer Management Costs
Early Intervention (DFM Reports)
Before contracts are signed, Ansix provides comprehensive Design for Manufacturability (DFM) reports including:
Draft angle recommendations
Wall thickness optimization
Gate location suggestions
Ejector pin mark location allowances
Customer Value: Problems are caught before steel is cut — no costly design changes after tooling is underway. Saves 30-50% of potential rework costs.
Trial Molding and Sampling
Ansix provides T0 through T3 trial samples, each accompanied by improvement reports. Quick-change inserts allow validation of different design variations without rebuilding entire molds.
Customer Value: Faster design iteration — customers can validate multiple concepts in a single tool. Reduces time-to-market.
Small-Batch Validation
Before full-scale production, Ansix offers 100-500 shot pilot runs with yield rate and CPK statistics — production only proceeds when stability is confirmed.
Customer Value: No surprises in mass production — customers approve based on real production data, not promises.
Maintenance and Spare Parts
Wear parts (ejector pins, core inserts) delivered with the mold
Maintenance service every 200,000 shots
Lifetime repair at cost
Customer Value: Predictable maintenance costs — no unexpected "surprise" repair bills. Extended mold life through professional care.
