IPX7 waterproof toothbrush supplier

For electric toothbrush brands, real-world durability is as important as cleaning performance. End users expect their device to withstand bathroom humidity, accidental splashes, and even short-term immersion in water. Therefore, many private-label brands actively look for an experienced OEM/ODM partner who can deliver true IPX7-grade waterproof reliability. As a supplier specializing in sealed structure engineering, we help you bring robust and market-ready oral care products to customers worldwide.

🌊 Why water resistance matters for electric toothbrush brands

Water exposure is unavoidable in bathroom environments. Consequently, the internal PCBA, motor, and battery must receive solid protection. Otherwise, the risk of malfunction increases and warranty costs rise. With IP-rated structural designs, reinforced sealing rings, and strict testing routines, we reduce these risks significantly.

Moreover, a reliable waterproof structure enhances brand positioning and customer trust, especially in premium or mid-high-end product lines.

We integrate engineering analysis with real-world testing. The casing, sonic vibration structure, and battery compartment are designed for long-term moisture resistance. Additionally, ultrasonic welding and seal optimization help maintain performance even after months of continuous use.
