6. Key Precautions for CNC Machining Pet Water Dispenser Prototypes
Qualität sicherstellen, Sicherheit, und Effizienz, observe these precautions:
- Safety Priority: All materials must be non-toxic (pass RoHS, FDA food-grade certifications); Avoid sharp edges (chamfer all pet-contact parts to R1mm); Stainless steel parts must be corrosion-resistant (prevent rust from contaminating water).
- Präzisionskontrolle: Sealing groove tolerance ±0.05mm (ensures waterproofing); Pump hole coaxiality ≤0.05mm (prevents vibration noise); Acrylic parts reserve ±0.1mm shrinkage (avoids post-machining size deviation).
- Kostenoptimierung: CNC machining is ideal for ≤100 units; Für die Massenproduktion (>1000 units), switch to injection molding (ABS/acrylic) to reduce cost by 50-60%. Simplify complex curves (Z.B., replace irregular tank shapes with regular cylinders) to shorten toolpaths.
- Umweltschutz: Use non-toxic, biodegradable coolants for machining; Dispose of plastic/metal waste in accordance with environmental regulations (recycle stainless steel scraps).
Standpunkt der Yigu -Technologie
Bei Yigu Technology, Wir glauben CNC machining is the core to developing safe and user-friendly pet water dispenser prototypes. It enables precise control of critical structures—from pet-safe edge chamfers (R1mm) to waterproof sealing grooves (± 0,05 mm)—and supports rapid iteration, which is vital for balancing functionality (circulation, filtration) and pet safety (non-toxicity, keine scharfen Kanten). When producing these prototypes, we focus on two core aspects: material-safety matching (acrylic for transparent tanks, food-grade stainless steel for connectors) und Prozessoptimierung (vacuum adsorption for acrylic, low-speed machining for stainless steel). By integrating strict quality control from design to testing, we help clients shorten development cycles by 20-25% and mitigate mass production risks. Blick nach vorn, we will apply AI-driven parameter optimization to CNC machining, further improving efficiency while maintaining ±0.03mm precision for safer, more reliable pet water dispenser prototypes.
