Waterproofing cannot be fully addressed through post-production sealing. The mold parting lines, buttons, ports, and speaker openings determine the achievable IP rating limit.

Key Decisions in the Design Phase

Target IP rating, testing methods, operating environments (rain/splash/dust).

Sealing Strategy: Choices Between O-Rings, Ultrasonic Welding, Gluing, And Waterproof Breathable Membranes.

Collaboration Between Appearance and Structure

Seams and Parting Lines Avoid Critical Waterproof Paths; Button Structures Reserve Waterproof Travel

Charging Port/Interface Solutions (Type-C Waterproof Female Connector, Magnetic, Cover Plate) Affect Overall Design.

Youtai Intelligent's Suggestions

Include IP targets in the design objectives list and review them in each design iteration.

Conduct sealing validation with samples that closely resemble the final process before mold making to reduce the risk of batch failures.
