Checks from incoming materials to shipment.
In-Process Checks
Check molding, tufting and assembly during production, identify and isolate nonconforming parts, and document the resolution.
Finished-Product Verification
Verify applicable appearance, function, water-resistance and reliability requirements under the model procedure. The 38-item list spans several stages.
Pre-Shipment Inspection
Check packaging, labels, quantity and order requirements. Carry out applicable package-drop or simulated-transport validation before shipment.
38 test items

Key tests
Understand what the tests evaluate.
IPX7 water-resistance check
Check handle sealing and water resistance; applicable handles receive unit-by-unit checks under their inspection procedure.
Reduce the risk of water ingress during normal cleaning and bathroom use.
Drop test
Simulate drops under the model-specific test conditions and check housing, joints and function.
Identify weak points and assess integrity after an accidental drop.
Motor life test
Run the motor continuously or in cycles under defined conditions, then review vibration, noise and function.
Validate stability over extended operation and detect early failures.
Bristle pull test
Check how firmly bristles remain fixed under the specified pull force.
Reduce the risk of abnormal bristle shedding.
Charge and discharge cycle test
Cycle the battery through charging and discharging and record capacity and operating performance.
Understand how battery performance changes over repeated use.
Package drop and simulated transport
Test the agreed packaging against handling impacts and transport vibration, then inspect the carton, insert and product.
Validate package protection and reduce transit-damage risk.
Process Advantages
Compare construction, finishes and drive options.
Copper-free tufting
Imported copper-free tufting equipment is used for selected brush heads, including the BJ-T9 option.
Offer a brush-head construction option distinct from traditional metal-anchor tufting.
End-rounded bristles
Selected DuPont-bristle heads receive an end-rounding process.
Rounded bristle tips support a smoother brushing feel. The end-rounding rate depends on the brush-head specification.
High-Density Bristle Tufting
Use a denser bristle arrangement on applicable heads.
Create options for brushing coverage and product differentiation.
Four-layer finish and three-color molding
BJ-T5B uses a four-layer exterior finish, while BJ-T9 uses a three-color molded design.
Provide two distinct appearance treatments for a differentiated range.
Magnetic-levitation sonic motor
BJ-Y2, BJ-T5B and the BJ-T6 family use magnetic-levitation sonic motors; stroke rates vary by model.
Support different cleaning modes and product specifications across the range.
Regulated drive
BJ-T3 uses a regulated drive and operates at 18,000–23,000 strokes per minute.
Help keep the vibration feel more consistent in use, subject to the sample and test conditions.
