Part One: Foundation of Capability — Hardware That Builds Customer Trust
1.1 Mold Processing Equipment — Precision That Eliminates Post-Processing Costs
Ansix Tech operates multiple five-axis high-speed machining centers capable of achieving complex surface geometries with machining accuracy up to ±0.002mm (2 microns). For float switch and valve products, this directly translates into:
Customer Value Delivered: Exceptionally smooth parting lines with no burrs or witness marks — eliminating the need for costly secondary finishing operations such as manual polishing, grinding, or deburring. One of the most common hidden costs in plastic component manufacturing is manual flash removal. By delivering molds that produce flash-free parts from the first shot, Ansix Tech eliminates these labor expenses entirely.
Customer Pain Point Solved: Traditional molds with visible parting lines require manual polishing or grinding before components can be assembled or delivered to customers. Ansix Tech's five-axis precision eliminates this entirely.
Slow-Wire EDM (Electrical Discharge Machining) Capability: Ansix Tech's wire EDM technology can produce features as fine as 0.03mm — micro-holes, narrow slots, and fine features that traditional machining cannot produce with consistency. For float switch products requiring precision sealing surfaces and intricate internal geometries, this capability ensures:
Thin-wall sections resist deformation during high-pressure injection
Every micro-feature is dimensionally exact from cavity to cavity
The mold maintains this precision over millions of cycles
On-Site Electrode Machining Workshop: Mold modifications and repairs rarely leave the Ansix Tech facility. Conventional steel replacement or welding can be completed within 24 hours.
1.2 Injection Molding Machine Fleet — Consistency Shot After Shot
Ansix Tech maintains 260 injection molding machines sourced from the world's most trusted brands: Japan's Fanuc, Sumitomo, Toshiba, and Nissei; Germany's Engel and Arburg (the latter specializing in two-shot and liquid silicone); alongside domestic leaders Haitian and Victor Taichung Machinery.
Clamping Force Range: 30 tons to 4,000+ tons, covering the complete spectrum from small precision float components to large-scale water tank fittings.
All-Servo Electric Drive Technology: Every machine is equipped with full servo motor drive systems, delivering repeatable process accuracy of ±0.1%.
Customer Value: Batch-to-batch consistency. When a customer validates a float switch design, they need to know that the 10,000th part is identical to the first. Servo drive technology and closed-loop control systems make this a reality.
Real-Time Process Monitoring: Injection Pressure, melt temperature, screw speed, and back pressure are continuously tracked. Energy efficiency — all-electric drives consume up to 60% less energy than conventional hydraulic systems, aligning with customer sustainability goals.
1.3 Quality Inspection and Metrology Equipment
Ansix Tech's quality laboratory is equipped with coordinate measuring machines (CMMs) and optical imaging systems capable of sub-micron resolution.
Full Dimensional Reporting: Every mold undergoes a full dimensional report before shipment, with Critical-to-Quality dimensions (CPK) maintained at ≥ 1.33. This statistical guarantee ensures dimensions will remain within tolerance during mass production.
Full Traceability: Every manufactured component is fully traceable.
Part Two: Mold Manufacturing — Core Competitiveness with Measurable Metrics

Customer Value: Balanced filling prevents short shots, reduces internal stress, minimizes warpage, and ensures consistent part weight from cavity to cavity.
2.4 Cooling System Design for High-Volume Production
For float switch and valve products requiring high-volume production, cooling system design is critical:
Conformal Cooling: Cooling channels follow the contour of the part geometry for uniform heat extraction
Zone Temperature Control: Mold temperature zones controlled independently to within 2°C differential between core and cavity
Reduced Cycle Time: Optimized cooling reduces molding cycle time by 15–30% compared to conventional cooling designs
Warpage Prevention: Uniform cooling minimizes differential shrinkage and part distortion
2.5 Ejection System Design
Proper ejection system design prevents part damage during demolding:
Balanced Ejector Pin Placement: Prevents part deformation during ejection
Surface Mark Control: Ejector pin witness marks placed in non-critical areas or minimized through optimized pin design
Floating Ejector Systems: For thin-walled float components to prevent puncture or distortion
Part Three: Injection Molding — Process Control That Reduces Quality Anxiety
