FEATURES
Hard Infrastructure – The Foundation of Customer Confidence
1.1 Mold Processing Equipment
Ansix Tech's equipment portfolio is not merely a list of machines; it is a guarantee of zero-defect production. Every piece of equipment is selected to eliminate variables that could jeopardize product quality.
Five-Axis High-Speed Machining Centers: The company employs 5-axis high-speed machining centers capable of machining complex curves with ±0.002mm precision. This ensures that product parting lines are smooth and burr-free—critical for float switch housings where sealing surfaces must be flawless to prevent liquid ingress. For customers, this translates to:
No secondary deburring operations, saving 5-8% in post-processing costs
Consistent aesthetic quality that protects brand reputation
Elimination of leak paths that could cause field failures
Slow-Wire Electrical Discharge Machining (EDM): Ansix Tech's slow-wire EDM technology handles 0.03mm micro-hole and narrow-slot processing, effectively eliminating thin-wall deformation common in competitive solutions. For float switch applications requiring precise reed switch positioning slots or venting holes, this capability ensures:
Accurate placement of magnetic reed switches for reliable multi-point control
No distortion in thin-wall sections that could affect float movement
Consistent switch actuation points across millions of production cycles
Coordinate Measuring Machines (CMM) and Optical Imaging Systems: Every mold undergoes 100% dimensional verification using CMM and optical inspection systems. A full dimensional report is provided with each mold, with critical dimensions validated to CPK ≥ 1.33—the industry gold standard for process capability.

Injection Molding Machine Fleet
Ansix Tech operates 260 injection molding machines spanning 30 tons to 4,000 tons of clamping force, covering product dimensions from micro-precision components weighing less than one gram to large structural parts exceeding several kilograms. The machine portfolio includes leading brands: FANUC, Sumitomo, Toshiba, Nissei, Engel, and ARBURG (primarily for liquid silicone rubber two-component molding).
All-Electric Servo-Driven Presses: All machines are equipped with all-electric servo drives, delivering repeatable injection accuracy of ±0.1%. This means:
Every float switch housing produced at 2:00 AM on a holiday weekend matches the first sample shipped
No drifting, no inconsistent fit, no sudden spike in reject rates
When assembly lines run at high speed, consistent part-to-part quality eliminates jams, reduces downtime, and protects brand reputation
Manufacturing Execution System (MES) Integration: All machines are connected through the MES system, which locks down every process parameter—temperatures, pressures, speeds, timing—restricting access to engineering approval only. This eliminates unauthorized adjustments that could compromise quality.

Mold Manufacturing Core Competencies – Measurable Commitments
Customers care about four things when they commission a mold: how many shots will it produce, how precise will the parts be, how fast can they get it, and what will it cost to maintain.
2.1 Mold Life Expectancy
Dimension Technical Specification Customer Value Translation
Mold Life Mold base in P20; core/cavity inserts in premium tool steel (S136, 2344, 2343, 8407, SKD11/61/DC53, M340/4Cr13/9Cr18, NAK80, H13) Your mold will not become a recurring capital expense. For glass-reinforced materials, Ansix guarantees 500,000 shots; for unfilled grades, 1,000,000 shots. A full material certification report and heat treatment curve are provided with every mold—complete transparency on what you are buying
For float switch applications where housings may be produced in glass-filled PBT or PA66 for enhanced structural strength, the 500,000-shot guarantee means customers can plan production for 3-5 years without mold replacement capital expenditure.
2.2 Attainable Tolerances
Feature Capability Customer Impact
General structural features ±0.05mm Standard features fit every time
Precision gears/medical components ±0.005mm Critical sealing surfaces and reed switch positioning slots achieve micron-level accuracy
For float switches, where reed switch alignment determines actuation point accuracy, ±0.005mm precision ensures:
Consistent switching points across all production units
No assembly-line rework for switch positioning
Reliable multi-point control with predictable actuation levels
2.3 Mold Type Offerings
Ansix Tech offers a comprehensive range of mold types:
Hot runner systems: Reduce runner waste to zero, eliminating material scrap and lowering per-part material cost
Stack molds: Double output per machine cycle, effectively doubling production capacity without additional capital investment
Two-shot/multi-material molds: Enable overmolding of different materials in a single cycle
High-gloss mirror-finish molds: Ra < 0.05μm for transparent or cosmetic applications
2.4 Gating Strategy Optimization
Using Moldflow simulation software, Ansix Tech predicts fill patterns, identifies weld-line locations, exposes air-trapping risks, and optimizes gate placement to ensure balanced flow across complex geometries. For float switch housings, this means:
No weld lines at critical sealing points that could become leak paths
No air traps that could cause incomplete filling or voids
Optimized gate location that minimizes visible witness marks on aesthetic surfaces
2.5 Cooling System Design
Ansix Tech simulates cooling performance to design conformal cooling channels that follow complex contours, reducing cycle times by up to 20% compared to traditional straight-line cooling layouts. For float switch production, this translates to:
Faster cycle times = higher output per machine = lower per-part cost
Uniform cooling = reduced warpage = better dimensional stability
Lower residual stress = improved long-term part reliability
2.6 Lead Time Standards
Mold Complexity Standard Lead Time Expedited Option
Simple molds 10 days -
Medium-difficulty molds 25-45 days 20 days (with validation steps preserved)
Even under expedited conditions, Ansix Tech ensures that validation steps are not skipped—every mold still undergoes full DFM analysis, Moldflow simulation, and dimensional verification before shipment.
