6. Key Precautions for CNC Machining Pet Feeder Prototypes
Qualität sicherstellen, Sicherheit, und Effizienz, observe these precautions:
- Safety Priority: All materials must be non-toxic (Lebensmittelqualität); Avoid sharp edges (chamfer pet-contact parts to R1mm); Gears must have smooth teeth (no burrs to prevent pet injury).
- Präzisionskontrolle: Gear tooth tolerance ±0.02mm (ensures smooth transmission); Sealing groove tolerance ±0.05mm (moisture protection); Food outlet size accuracy ±0.1mm (prevents clogging).
- Kostenoptimierung: CNC machining is ideal for ≤100 units; Für die Massenproduktion (>1000 units), switch to injection molding (ABS/PC parts) to reduce cost by 50-60%. Simplify complex curves (Z.B., replace irregular food bin shapes with cylinders) to shorten toolpaths.

Standpunkt der Yigu -Technologie
Bei Yigu Technology, Wir glauben CNC machining is the core to developing safe and functional pet feeder prototypes. It enables precise control of critical structures—from gear teeth (±0.02mm accuracy) to pet-safe chamfers (R1mm)—and supports rapid iteration, which is vital for balancing functionality (timed dosing, quiet transmission) and pet safety (non-toxicity, keine scharfen Kanten). When producing these prototypes, we focus on two core aspects: material-function matching (POM for low-noise gears, food-grade ABS for bins) und Prozessoptimierung (spiral interpolation for gear teeth, vacuum adsorption for acrylic). 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 more reliable pet feeder prototypes.
FAQ
- What materials are best for CNC machined pet feeder prototype components, und warum?
The best materials depend on components: ABS/PC alloy for gear boxes (hohe Starrheit, Tragenresistent); POM plastic for gears (geringe Reibung, quiet); food-grade ABS/acrylic for food bins (ungiftig, leicht zu reinigen); aluminum alloy for fixed brackets (korrosionsbeständig). These materials balance machinability, Funktionalität, and pet safety.
