1. MACCHINAZIONE PRE-CNC: Design and Preparation for Pet Water Dispenser Prototypes

Before initiating MACCHING CNC for the pet water dispenser prototype, a systematic design and preparation stage is critical to meet functional, sicurezza, and pet-friendly requirements. Questa fase segue una sequenza lineare, con dettagli chiave organizzati nella tabella seguente.

Passaggio di progettazioneRequisiti chiaveMateriali consigliati
Analisi della domanda del prodottoFunzioni core: Automatic circulation (pump flow 500-800mL/min) or manual refill; Capacità: Water tank (1-2l); Additional features: filtration system (replaceable filter element), splash-proof edge (height ≥15mm), low-water level reminder; Sicurezza: No sharp corners (pet mouth protection), Materiali non tossici; Reserve space for pump, filter tank, water pipe interface (Φ8-10mm), and power port (DC 5V).
Design strutturaleSplit components: Water tank (upper/lower), base, pump support, filter tank, water pipe connector; Optimize internal flow path (smooth water circulation, no dead corners); Design sealing grooves (larghezza 2-3 mm, depth 1-1.5mm) for waterproofing; Add anti-slip pads (silicone) on base bottom.
3D Modellazione & DisegnoUsa il software CAD (Solidworks, E nx) to create 3D models (tolerance ±0.1mm for plastic, ±0.05mm for metal); Segna le dimensioni chiave: Water tank inner diameter (matches capacity), pump mounting hole (Φ30mm), filter tank size (fits standard filter); Export 2D drawings (Dxf) with surface roughness requirements (Ra3.2 for water contact parts).
Selezione del materialePrioritize non-toxicity, Resistenza alla corrosione, e macchinabilità, matching mass production standards.Water Tank/Base: Acrilico (trasparente, easy to observe water level) o addominali (non tossico, resistente all'impatto, spessore 2-3 mm); Pump Support/Filter Tank: ABS/PC alloy (isolamento, resistente all'usura); Water Pipe Connector: Acciaio inossidabile 304 (resistente alla corrosione, grado alimentare); Internal Brackets: Nylon PA66 (non tossico, leggero).
Pretrattamento dei materialiTagliare le materie prime in spazi vuoti (lasciare un margine di lavorazione di 0,5-1 mm): Acrylic/ABS via laser cutting, stainless steel via bandsaw; Anneal stainless steel (1050-1100° C per 1-2 ore) per ridurre lo stress; Dry ABS/acrylic (80-100° C per 2-3 ore) per rimuovere l'umidità (prevents machining bubbles); Clean blanks with alcohol to remove oil.

6. Key Precautions for CNC Machining Pet Water Dispenser Prototypes

Per garantire la qualità, sicurezza, ed efficienza, 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).
  • Controllo di precisione: 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).
  • Ottimizzazione dei costi: CNC machining is ideal for ≤100 units; Per la produzione di massa (>1000 units), switch to injection molding (ABS/acrylic) to reduce cost by 50-60%. Simplify complex curves (PER ESEMPIO., replace irregular tank shapes with regular cylinders) to shorten toolpaths.
  • Protezione ambientale: Use non-toxic, biodegradable coolants for machining; Dispose of plastic/metal waste in accordance with environmental regulations (recycle stainless steel scraps).

Yigu Technology’s Viewpoint

Alla tecnologia Yigu, Crediamo 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, no sharp edges). When producing these prototypes, we focus on two core aspects: material-safety matching (acrylic for transparent tanks, food-grade stainless steel for connectors) e ottimizzazione del processo (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. Guardando avanti, 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.
