6. Key Precautions for CNC Machining Electric Face Wash Prototypes
To ensure quality and safety, observe these precautions:
- Safety Priority: Ensure IPX7 waterproof (sealing groove precision ±0.05mm); Isolate motor from water (use waterproof gaskets) pour éviter les courts-circuits.
- Contrôle de précision: Maintain coaxiality of motor and brush head (≤0,05 mm) to avoid vibration noise; Ensure thread accuracy of brush head interface (6H) for easy assembly.
- Optimisation des coûts: CNC machining is ideal for ≤100 units; Pour la production de masse (>1000 units), switch to injection molding (ABS/PC housing) + moulage en silicone (brush head) to reduce cost by 50-60%. Simplify complex grip curves to reduce tool wear.
- Material Care: ABS/PC is prone to moisture absorption—dry before machining to avoid bubbles; Aluminum alloy is prone to deformation—control cutting temperature (use cutting fluid) and clamping force.
Point de vue de la technologie Yigu
À la technologie Yigu, nous croyons CNC machining is the core to developing safe and user-friendly electric face wash prototypes. It enables precise control of critical structures (Par exemple, ±0.05mm motor-brush coaxiality, IPX7 waterproof grooves) and supports rapid iteration—critical for face wash products where safety (étanche, isolation) and user experience (ergonomics, vibration comfort) are paramount. When producing these prototypes, we focus on two core aspects: material-safety matching (ABS/PC for waterproof housing, medical silicone for skin-friendly brush heads) et l'optimisation du processus (vacuum adsorption for thin-walled parts, layered cutting for thread precision). By integrating strict quality control from design to testing, we help clients shorten development cycles by 20-25% and mitigate mass production risks. Regarder vers l'avenir, we will apply AI-driven parameter optimization to CNC machining, further improving efficiency while maintaining ±0.03mm precision for more reliable face wash prototypes.
FAQ
- What materials are best for CNC machined electric face wash prototype housings, et pourquoi?
The best materials are ABS/PC alloy and aluminum alloy 6061. ABS/PC alloy offers excellent waterproof performance (IPX7 compliance) et résistance à l'impact (no cracks from 1m drops), while aluminum alloy 6061 est léger (≤150g) and easy to polish (smooth grip). Both are easy to machine, ensuring precise internal structures for motors and brush heads.
- Can CNC machined electric face wash prototypes be used directly for mass production?
Non. CNC prototypes are for design verification, market research, and small-batch customization (≤100 units). Pour la production de masse (>1000 unités), moulage par injection (ABS/PC housing) + moulage en silicone (brush head) is better—it reduces per-unit cost by 50-60% and increases production speed. CNC prototypes provide data to optimize injection molds (Par exemple, adjust shrinkage for ABS/PC).
- How long does it take to produce a CNC machined electric face wash prototype?
The cycle depends on complexity. Un prototype simple (ABS/PC housing, basic vibration function) prendre des prises 6-8 jours: 1-2 days for design, 2-3 days for CNC machining, 1-2 jours pour le post-traitement, et 1 day for assembly/testing. Un prototype complexe (aluminum alloy housing, multi-gear vibration, IPX7) prendre des prises 9-12 jours (more intricate machining and waterproof testing).
