FEATURES
Hard Power Infrastructure – Building Customer Trust Through Equipment Excellence
Mold Processing Equipment
Ansix's mold manufacturing facility is equipped with state-of-the-art machining centers that form the backbone of precision toolmaking:
Five-Axis High-Speed Machining Centers: Ansix employs advanced five-axis high-speed CNC machining centers capable of achieving 0.002mm precision on complex curved surfaces. This capability ensures that product parting lines remain smooth and burr-free, directly translating to superior product aesthetics and functional sealing performance. For float switch applications where the housing must maintain liquid-tight integrity, this precision is non-negotiable.
Slow-Wire EDM (Electrical Discharge Machining): The company utilizes slow-wire EDM equipment capable of machining 0.03mm fine micro-holes and narrow slots. This technology is essential for creating the intricate internal passages, magnet housing cavities, and precision fit surfaces required in float switch components. The non-contact nature of EDM prevents thin-wall deformation—a critical advantage when machining stainless steel float bodies that require consistent wall thickness for buoyancy accuracy.
CNC EDM Sinker Machines: Complementing the wire EDM capability, Ansix's CNC sinker EDM machines enable the creation of complex three-dimensional cavities with exceptional surface finishes. This is particularly valuable for molding components that require high-gloss or textured surfaces.

- The mold manufacturing process and product material selection
Precision Surface Grinding and Jig Grinding: Ultra-precision grinding equipment ensures that mold base plates, cavity inserts, and core pins achieve the flatness and parallelism required for flash-free molding.Injection Molding Machine FleetAnsix operates a comprehensive range of injection molding machines with clamping forces spanning from 30 tons to 4000 tons. This extensive range enables the company to produce everything from miniature float switch components to large multi-point level switch assemblies.All-Servo Electric Drive Systems: All molding machines are equipped with all-servo electric drives, delivering stable repeatability precision of ±0.1%. This means that every single shot—whether the first or the hundred-thousandth—maintains identical dimensional characteristics. For customers, this translates to predictable assembly fit, consistent switch actuation points, and zero unexpected variations in production quality.Real-Time Process Monitoring: Each machine is networked to a central MES (Manufacturing Execution System) that locks all molding parameters—temperature, pressure, injection speed, and holding time. Only authorized engineers can adjust these parameters, ensuring that production runs remain consistent across shifts, days, and even years of production. -
Inspection and Metrology Equipment
Coordinate Measuring Machines (CMM): Ansix employs high-precision CMM equipment for full-dimensional inspection of both mold components and finished parts. Every mold undergoes complete dimensional verification before shipment, with critical dimensions documented and certified.
Optical Imaging and Vision Inspection Systems: High-resolution optical measurement systems enable rapid, non-contact inspection of complex geometries. These systems are particularly valuable for verifying the precision of fine features such as O-ring grooves, sealing surfaces, and mounting threads.
Surface Roughness Testers: Surface finish is critical for both the aesthetics and functional performance of float switches. Ansix uses precision surface roughness testers to verify that all molded surfaces meet specified Ra requirements.
Key Performance Indicator: Every mold delivered by Ansix includes a full dimensional report with critical dimensions verified to achieve CPK ≥ 1.33—demonstrating process capability that exceeds industry standards.
Part II: Mold Manufacturing Core Competencies – Speaking the Language of Customer Value
Mold Life and Durability
Customers are primarily concerned with how long a mold will last before requiring expensive repairs or replacement. Ansix addresses this concern through meticulous material selection and热处理 processes:
Mold Component Material Grade Hardness Application
Mold Base P20 (Pre-hardened) HRC 28-32 Structural support, cost-effective
Cavity/Core Inserts S136 (Stainless) HRC 48-52 Corrosion resistance, mirror finish capability
Wear-Resistant Inserts 2344 / 8407 / H13 HRC 46-52 High-wear areas, glass-filled materials
Precision Components SKD11 / DC53 HRC 58-62 Punches, ejector pins, high-wear details
High-Polish Applications NAK80 HRC 38-42 Transparent parts, aesthetic surfaces
Performance Commitments: Ansix guarantees mold life of 500,000 cycles for glass-fiber reinforced materials and 1,000,000 cycles for standard engineering plastics. Each mold is delivered with material certificates and heat treatment curves, providing full traceability and confidence in long-term performance.
Achievable Tolerances
Precision is the currency of customer confidence. Ansix's capabilities span a wide range:
Standard Structural Components: ±0.05mm
Precision Gears and Medical-Grade Components: ±0.005mm
Critical Fit Surfaces: ±0.01mm
For float switch applications, where the actuation point depends on precise float positioning, these tolerances ensure consistent switching performance across millions of cycles.
Mold Types and Configurations
Ansix's mold-making expertise encompasses a comprehensive range of mold types:
Hot Runner Systems: Reducing material waste and cycle times while improving part quality. Hot runner molds eliminate runner scrap, reducing material costs by 15-30% for high-volume production.
Stack Molds: Doubling production efficiency by molding two layers of parts simultaneously. For high-volume float switch components, stack molds can effectively double output without additional machine investment.
Two-Shot / Multi-Material Molds: Enabling the production of components with multiple materials in a single molding cycle—essential for overmolding magnetic elements or creating soft-touch sealing features.
High-Gloss Mirror-Finish Molds: Achieving surface roughness Ra < 0.05μm, essential for transparent float bodies or components requiring optical clarity.
Gate and Runner System Design
Using advanced mold flow analysis software (Moldflow), Ansix predicts weld line locations, air trap positions, and fill imbalances before steel is cut. This proactive approach enables:
Optimization of gate locations and quantities
Balanced cavity filling across multi-cavity molds
Elimination of visible weld lines on aesthetic surfaces
Prevention of short shots and incomplete fills
Customer Value: No costly mold modifications after sampling. No surprises during production ramp-up.
Standard Lead Times
Mold Complexity Standard Lead Time Expedited Option
Simple Molds 10 days —
Medium Complexity 25-45 days 20 days (with validation maintained)
High Complexity 45-60 days 35 days
Ansix maintains that expedited delivery never compromises the validation process. Every mold, regardless of timeline, undergoes full dimensional verification and sample validation before shipment.
Part III: Injection Molding Process Control – Eliminating Customer Quality Anxiety
What Customers Fear
The most common quality concerns in injection molding are:
Shrinkage and sink marks
Flash and burrs
Dimensional instability between batches
Color variation between batches
Process Standardization and Control
MES-Integrated Parameter Locking: All machine parameters—temperatures, pressures, speeds, and times—are locked within the MES system. Only authorized engineers can modify settings, and all changes are logged with full traceability. Each production batch includes first-article and last-article inspections, ensuring consistency from start to finish.
Dimensional Stability Control
Zone Temperature Control: Ansix employs mold temperature controllers with zone-specific control, maintaining core and cavity temperature differentials within 2°C. This minimizes warpage and distortion—critical for float switch components that must maintain precise buoyancy characteristics.
Real-World Performance Data: For a representative bracket component, Ansix demonstrated that across three consecutive production batches over one week, critical hole spacing variation remained ≤ 0.02mm. This level of stability enables customers to design assemblies with confidence, knowing that every part will fit perfectly.
Surface Quality Grades
Ansix achieves surface quality levels that meet the most demanding specifications:
Application Surface Requirement Ansix Capability
Transparent Components No bubbles, no flow lines Ra ≤ 0.05μm
Plating-Ready Surfaces No gas marks SPI A-1 grade
