-
Uniform Coating: Provides uniform coating on workpieces through automated spraying equipment, enhancing product quality.
-
Versatile Processes: Supports multiple coating processes, such as primer and topcoat application, curing, etc., to meet the needs of different workpieces.
-
Environmental Friendliness: Equipped with advanced exhaust gas treatment systems to reduce environmental pollution.
3. Process Flow
The process flow of the heavy-duty overhead conveyor coating production line typically includes the following main steps:
| No. | Process Name | Process Description |
|---|---|---|
| 1 | Workpiece Hanging | Heavy workpieces are loaded onto the overhead conveyor system, preparing for the coating process. |
| 2 | Pre-treatment | Includes degreasing, rust removal, and phosphating to clean the workpiece surface and enhance coating adhesion. |
| 3 | Primer Coating | Automated spraying equipment is used to evenly apply primer, enhancing the corrosion resistance of the workpiece. |
| 4 | Primer Curing | The workpiece coated with primer is sent into the curing oven, where the primer is cured through heating. |
| 5 | Topcoat Coating | After the primer is cured, topcoat is applied to enhance the appearance quality of the workpiece. |
| 6 | Topcoat Curing | The workpiece coated with topcoat is sent into the curing oven again to cure the topcoat. |
| 7 | Inspection and Repair | The coated workpiece is inspected for defects such as uneven coating or scratches, and repairs are carried out if necessary. |
| 8 | Workpiece Unloading | The completed workpiece is unloaded from the overhead conveyor system for subsequent processes or storage. |
