4. Coating of Hardware Tools and Metal Products

Widely applied in the surface finishing of metal tubes, profiles, tools, and equipment frames, enhancing scratch resistance, corrosion protection, and overall product durability—ultimately improving market competitiveness.


Product Operate Guide

Before use, please ensure that the gearbox model is compatible with the powder coating equipment. Inspect the drive shaft, connection flanges, and mounting holes to confirm they are intact and undamaged. Ensure coaxial alignment is accurate and stable to prevent additional load during operation.

The gearbox is pre-filled with lubricant before delivery; check the oil level prior to initial startup to ensure adequate lubrication. Verify that all seals are intact to prevent powder intrusion, which could affect transmission efficiency.Connect the motor to the gearbox via coupling or drive shaft and adjust the rotation direction accordingly. After wiring, perform a no-load test run for 2–5 minutes to confirm smooth operation with no abnormal noise or leakage, then proceed to full operation.Regularly inspect bearings and gear wear conditions, and carry out timely maintenance to ensure long-term reliability.
