Waterproof enclosures protect sensitive electronics and mechanical components in outdoor and harsh environment applications. Proper design and fabrication are critical for long-term reliability.
IP Rating Fundamentals
The Ingress Protection (IP) rating system defines the level of protection against solids and liquids. For outdoor equipment, IP65 (dust-tight and protected against water jets) is typically the minimum requirement, with IP67 or IP68 needed for temporary or continuous immersion.
Design Best Practices
- Continuous weld seams with full penetration on all external joints
- Sloped tops to prevent water pooling
- Proper gasket groove design with compression ratios of 20-30%
- Drain holes at low points with protective covers
- Cable entry points with appropriate gland fittings
Testing and Validation
We perform water spray testing and pressure decay testing on all waterproof enclosures to verify seal integrity before shipment. For critical applications, we can arrange third-party IP certification testing.
