At MIO Technology, we are a source factory for portable water flossers and oral irrigators. One of the most critical components inside every water flosser is the motor. The motor directly affects the device’s performance, lifespan, and user experience. That’s why we follow a strict motor gear assembly and testing process to ensure reliability before any unit moves to final assembly.
Here’s our 4‑step process:
Step 1 – Incoming Inspection
We begin by inspecting every gear for any damage or deformation, and each motor for oxidation or broken pins. Only components that pass this visual and functional check enter the production line.
Step 2 – Gear Pressing
The operator turns on the power and starts the automatic pressing machine. After connecting the air hose (0.6 MPa), the motor and gear are placed into their respective slots. Once the start switch is toggled, a pneumatic cylinder horizontally presses the motor shaft into the gear with precise force. This ensures a tight, stable fit without damaging the motor or gear.
Step 3 – Pin Bending & No‑Load Current Test
After pressing, the motor pins are bent to approximately 90° and placed into a testing fixture. We then run a no‑load current test at rated voltage. The acceptable current must be ≤ 0.3A. This test verifies that the motor operates efficiently without abnormal resistance or internal short circuits. Motors that exceed the limit are rejected.
Step 4 – Sorting and Traceability
Good units move to the next production stage (e.g., pump assembly). Defective units are clearly marked and placed in a designated area for further analysis or rework. Every motor and gear is traceable to its batch.
Why This Matters for Your Brand
Consistent motor performance means fewer returns, longer product life, and happier end users. As an OEM and private label manufacturer, we apply the same rigorous testing to every water flosser – whether you order 1,000 or 50,000 units.
