FEATURES
Hard Power Infrastructure — Building Trust Through Measurable Equipment Capability
1.1 Mold Manufacturing Equipment: Precision That Delivers Value
The foundation of any high-quality cap mold lies in the precision of its machining equipment. Ansix Tech has invested in world-class manufacturing assets from Mikron, Makino, and Frank to ensure every component meets exacting specifications.
Five-Axis High-Speed Machining Centers
Our five-axis CNC technology allows cutting tools to approach the workpiece from any direction in a single setup, eliminating multiple clamping operations and manual intervention. For caps with 24–38 teeth and double-layered construction, this capability translates directly into customer value:
Smoother Parting Lines, Zero Flash: Complex freeform parting surfaces are machined with seamless transitions, eliminating the gaps that cause flash—those thin, unwanted plastic layers that require costly manual deflashing. Your caps come off the machine ready for secondary processing, saving 5–15 seconds of labor per part.

- The mold manufacturing process and product material selection
±0.002mm Accuracy: Multi-cavity molds (up to 48 cavities) achieve identical dimensions across every cavity, ensuring that cap number one and cap number forty-eight fit the same bottle neck with zero variation.
Thin-Wall Protection: The high-speed, low-force cutting strategy prevents deformation of thin-walled features, preserving the integrity of child safety locking mechanisms and inner cap sealing surfaces.
Slow Wire EDM (Wire-Cut Electrical Discharge Machining)
For cap molds requiring fine features such as child-resistant locking tabs, internal splines, or narrow cooling channels, our wire EDM capabilities deliver exceptional precision. Advanced slow wire EDM machines can achieve ±0.002mm accuracy with surface roughness down to Ra0.4μm, and can process features as fine as 0.03mm.
Prevents Thin-Wall Deformation: Traditional machining of delicate features risks deformation. Our EDM process eliminates this risk entirely.
-
Absolute Precision in Thread-Forming Geometry: For caps with precise thread engagement requirements (essential oil caps and child safety closures), EDM ensures every thread tooth is dimensionally exact.
70% Automated Machining Ratio: High automation reduces human error and ensures consistency across mold components, delivering predictable mold quality, faster delivery, and reduced risk of assembly mismatches.
1.2 Injection Molding Machine Fleet: Consistency from First Shot to Last
Ansix Tech operates 260 injection molding machines with clamping forces ranging from 30 to 2,800 tons, covering every product size from miniature caps for personal care products to large closures for industrial containers.
All-Servo Electric Drive Systems
Our machines are equipped with all-servo motor drives that deliver repeatable precision of ±0.1%.
Batch-to-Batch Consistency: Multiple production runs over weeks or months produce identical cap dimensions. Your capping machinery will seat caps with consistent torque, reducing waste from improper seals.
Lower Per-Part Energy Cost: All-servo systems consume significantly less energy than hydraulic alternatives, directly reducing your electricity cost per cap.
Tonnage Range Coverage:
Tonnage Range Application for Caps
30–150 tons Small cosmetic caps, pharmaceutical closures (24–28 teeth), fine-thread precision parts
150–800 tons Standard caps (30–32 teeth), essential oil closures, child safety caps
800–2,800 tons Large industrial caps (38 teeth), multi-cavity high-volume production
1.3 Inspection and Quality Equipment: Data-Driven Validation

Part Two: Mold Manufacturing Core Competencies — Value in Specific Metrics
2.1 Mold Steel Selection and Life Expectancy
“A mold is not a block of steel—it is a profit engine for your operation.”
The selection of mold steel directly determines production uptime, maintenance frequency, and total cost of ownership. Ansix Tech categorizes molds into five SPI classes based on cycle life and production volume requirements.
SPI Class Cycle Life Typical Steel Application for Caps
101 1,000,000+ cycles Premium tool steel (H13, S136 ESR, 8407) High-volume caps, 48+ cavities, glass-filled materials
102 500,000–1,000,000 cycles Hardened steel (2344, 2343, DC53) Medium-volume caps, 32–48 cavities
103 300,000–500,000 cycles Pre-hardened steel (P20, NAK80) Low-to-medium volume caps, prototype to production
104 100,000–300,000 cycles Aluminum or softer tool steel Pilot runs, low-volume specialty caps
105 ≤100,000 cycles Standard steel Prototype and bridge tooling
For double-layered and child safety caps that require high wear resistance on thread-forming surfaces, Ansix Tech typically selects S136 stainless steel (martensitic chromium stainless steel) for its superior corrosion resistance and excellent polishability, or H13 tool steel for its hot hardness and wear resistance in glass-filled applications.
Customer Value Delivered:
100% Uptime Assurance: With 101-class tooling, you can run full production schedules without unplanned mold maintenance interruptions.
Predictable Maintenance Costs: We deliver spare wear parts (ejector pins, core inserts) with every mold, and provide costed maintenance schedules at 200,000-cycle intervals.
Material Compatibility: Our steel selection accounts for your specific resin (PP, PE, PC, ABS, glass-filled compounds), preventing premature wear that would otherwise shut down your production line.
2.2 Achievable Tolerances and Part Quality
Feature Type Achievable Tolerance Customer Value
General structural features ±0.05mm Consistent fit with bottle necks
Precision gear teeth (24–38 teeth) ±0.005mm Smooth thread engagement, consistent torque
Parting line surface Flash ≤0.03mm No manual deflashing required
Concentricity ≤0.02mm Uniform wall thickness, no wobble
2.3 Gate and Runner System Optimization
Through advanced mold flow analysis using Moldex3D and Moldflow software, Ansix Tech predicts and eliminates defects before steel is cut.
Weld Line Prediction and Elimination: Flow simulation identifies where melt fronts meet—potential weak points that can compromise cap strength or aesthetics. For caps with 24–38 teeth, proper gate placement ensures that weld lines are either eliminated or positioned in non-critical areas.
Air Trap Detection: Simulation identifies regions where trapped air could cause burns or voids. These are resolved through optimized venting design before production begins.
Balanced Fill for Multi-Cavity Molds: For 32-cavity or 48-cavity cap molds, simulation ensures that all cavities fill uniformly, guaranteeing that cavity 1 and cavity 48 produce identical caps.
Customer Value: Zero trial-and-error iterations. Your first mold trial produces usable samples, reducing development time by 30–50% and eliminating the hidden costs of multiple mold reworks.
2.4 Cooling System Design for Production Efficiency
Cooling typically accounts for 60–80% of the total injection molding cycle time. Efficient cooling is the single most important factor in reducing per-part cost.
Conformal Cooling Technology
Ansix Tech designs cooling channels that follow the contour of the cap geometry, using advanced simulation to achieve uniform heat extraction. For double-layered caps, this means:
Core-to-Cavity Temperature Differential ≤2°C: Eliminates warpage and shrinkage variation.
Cycle Time Reduction of 15–30%: Faster cooling means more parts per hour without quality compromise.
Uniform Part Dimensions: Temperature uniformity across the mold cavity ensures that every cap shrinks identically as it cools.
Part Three: Injection Molding Process Control — Eliminating Customer Quality Anxiety
3.1 Process Standardization and MES Integration
All Ansix Tech injection molding machines are connected to a Manufacturing Execution System (MES) that locks down every process parameter—temperature, pressure, injection speed, and cooling time.
Parameter Lockdown: Only authorized engineers can adjust parameters. Each adjustment is logged with timestamp and operator ID.
Real-Time Alarm Triggers: If any parameter drifts outside control limits, the system alerts operators immediately, preventing out-of-spec production from continuing.
First-Article and Last-Article Inspection: Every batch is validated with before-and-after dimensional checks, ensuring that the first cap and the last cap in a production run are identical.
Customer Value: Your incoming quality inspection becomes a formality. With fully traceable, locked-in process parameters, you can trust that every shipment meets your specifications.
3.2 Dimension Stability Control
Temperature-Zoned Mold Control ensures that core and cavity temperatures are independently regulated and maintained within ±2°C differential across the entire mold face. For threaded caps with 24–38 teeth, this eliminates shrinkage variation that would otherwise cause inconsistent thread engagement.
In-Mold Pressure and Temperature Sensors provide closed-loop feedback to the injection molding machine. Real-time adjustments to packing pressure compensate for material viscosity variations between batches.
Metric Achieved Performance
Key hole spacing variation over 7-day continuous production ≤0.02mm
Torque consistency across 100,000 parts ±3% of target
3.3 Appearance Standards
Finish Type Achievable Standard
Frosted/Matte finish Uniform texture depth, no flow lines, no sink marks
Transparent/clear caps No bubbles, no flow marks, no visible weld lines
High-gloss caps Surface roughness Ra ≤0.2μm
3.4 Material Processing Capabilities
Ansix Tech has extensive production experience with a wide range of materials essential for cap applications:
Material Typical Application for Caps
PP (Polypropylene) Essential oil caps, food-grade closures, general screw caps—excellent chemical resistance and low cost
HDPE Industrial caps, child safety caps—superior impact toughness
PC (Polycarbonate) Transparent caps for premium cosmetics
ABS Decorative caps requiring high gloss or plated finishes
Nylon/PA6+GF30 High-strength caps requiring resistance to aggressive chemicals
PBT Caps requiring excellent electrical properties and dimensional stability
LCP Ultra-thin wall caps for medical or high-heat applications
PC/ABS blends Caps requiring a balance of impact strength and heat resistance
Part Four: End-to-End Service — Reducing Customer Management Costs
4.1 Early Intervention with DFM (Design for Manufacturability) Reports
Before any steel is cut, Ansix Tech provides a comprehensive DFM report.
What the DFM Report Includes:
Draft Angle Recommendations: All surfaces parallel to mold opening direction receive appropriate draft (typically ≥1° for smooth surfaces, ≥3° for textured matte/frosted finishes).
Wall Thickness Optimization: Uniformity ratio maintained within 1:3 to prevent sink marks and warpage.
Gate Location and Ejector Pin Placement: Identifies where gate vestige and ejector pin marks will appear, allowing you to approve placement on non-critical surfaces.
Thread Undercut Analysis: For screw-on caps with internal threads, the DFM specifies the unscrewing mechanism—rotating core, collapsible core, or forced ejection—and predicts cycle time implications.
Customer Value: You discover all manufacturability issues before committing to tooling investment. Rework that would cost tens of thousands of dollars in steel modifications is resolved in CAD at zero cost.
4.2 Sample Validation and Rapid Changeover
T0–T3 Sample Deliverables:
Stage Deliverable Purpose
T0 First sample from fresh mold Validate basic mold functionality and part geometry
T1 Improved sample with initial fixes Confirm dimensional accuracy and surface finish
T2 Optimized sample with process refinement Validate cosmetic appearance and sealing performance
T3 Production-ready sample Sign-off before mass production
Fast Changeover for Design Iterations: For double-layered caps where the inner cap or sealing geometry requires modification, Ansix Tech’s modular mold design allows core inserts to be replaced in 24 hours rather than rebuilding the entire mold.
Customer Value: This modular approach reduces engineering change costs by up to 60% and eliminates the weeks-long delays associated with full mold modification.
4.3 Pilot Run (Pre-Production Validation)
Before authorizing full production, Ansix Tech provides a pilot run of 1,000–5,000 caps.
Yield and Cpk Analysis: Production yield and process capability indices (Cpk) are calculated and reported.
Cap-to-Bottle Fit Validation: Caps are tested on your bottle necks or on standard gauges to verify sealing torque and thread engagement.
Child Safety Mechanism Verification (for child-resistant caps): Testing confirms that the cap meets applicable safety standards (ASTM F2054, CPSC requirements).
Customer Value: You approve mass production based on actual statistical data, not theoretical promises. The risk of receiving a shipment of 500,000 defective caps is eliminated.
