Electric Toothbrush Testing
Before your product reaches the market, it should pass real testing.
From waterproof testing and reliability testing to drop, vibration, toothpaste resistance, and life cycle tests, we verify each finished electric toothbrush under practical use and transportation conditions. This helps you reduce quality risks, protect your brand reputation, and deliver a more stable product to your customers.
Part One
Waterproof Reliability Test
Before your electric toothbrush reaches the market, we test its waterproof structure under both standard and stricter conditions. This helps reduce water-ingress risk, charging failure, and after-sales problems.
