Powder coating is a popular method of applying a protective and decorative finish to a wide range of poles. This process involves applying a dry powder to a surface and then heating it to create a smooth and durable coating. The key advantage of powder coating is its ability to provide a high-quality finish that is resistant to chipping, scratching, and fading. One of the main benefits of powder coating is its environmental friendliness. Unlike traditional liquid coatings, powder coating does not contain harmful solvents that can be released into the air during the curing process. This makes powder coating a more sustainable option for businesses looking to reduce their environmental impact. In addition to being eco-friendly, powder coating also offers a wide range of color options and finishes, allowing for endless customization possibilities.
Well,how to process the powered coating?let's follow below sheet:

Preparation |
1. For the rod vehicles that have been galvanized and put into the waiting area, check 3 rods with a thickness of more than 86 microns in each batch to check whether there is any missing plating. If they meet the standard, they can enter the operating area for unloading. 2. The operator checks and installs the door, screw and nut on the galvanized rod. 3. After the rod inspection door and screw are installed, they will be stacked in front of the calibration machine for 100% backtest calibration, which will be carried out by professional operators. After the first rod is calibrated, it will be verified by the calibration personnel, and all production can only be carried out after reaching the specified standards. |

Polishing |
1. After the bar is calibrated, it enters the polishing machine or shot blasting machine for polishing and grinding. The operator is required to wear protective clothing, dust masks and glasses. The polishing machine first throws the bar as a whole. Some places cannot work. The operator grinds with a small angle grinder. 2. For hanging zinc, the operator should carefully polish the dead corners of zinc slag to make it smooth. 3. If there are sand holes in the welding seam, leakage holes in the root parts or unevenness in the welding place, it should be filled with atomic ash in time and then polished, and the bumps or collisions should be repaired and polished in time until the inspection reaches the standard. 4. The polished rods and accessories are transported to the plastic- sprayed water catenary to wait for the pendant to be sprayed. |

| Plastic spray matters |
1. Before spraying, check and test run all the equipment on the assembly line to confirm that all the powder spraying equipment is static, conductive, components are grounded, and the air pressure is normal. 2. Cables and powder hoses must be free from scratches and damages, and all procedures are normal. 3. The operator needs to wear cotton dust-proof overalls, conductive shoes, dust-proof masks and glasses, and operate with bare hands. 4. After confirming the required powder and color are correct, take it out from the warehouse and calculate the required amount. 5. Turn on the assembly line system to run, all operators are in place, the front row is arranged for the upper part to wear safety helmets and protective shoes, and the rear row of the pendant rod is arranged for the same personnel to lower the part at a speed limit of 3 meters per minute. Hang the rod and then blow the dust , In addition to oil. 6. Turn on the spraying equipment and automatic spray gun. The pressure of the spray gun is 8-10 air pressure. First spray a sample for proofing. 7. The automatic assembly line moves forward at a constant speed of 3 meters per minute, and the loading and unloading will automatically stop for 6 minutes in the middle. If you find that the time is not enough or there is an accident, you can press the pause button. 8. The assembly line system normally has 3 hanging beams in the front row, 5 on the left and 6 on the right, and 8 hanging beams in the rear row in the constant temperature room. 9. When the constant temperature control box is started, it can reach the predetermined 200 degrees ± 10 in 45 minutes. 10. Each batch of goods needs to be counted before spraying. |

| Product packaging |
1. The operator must conduct self-inspection on the rod after spraying, whether it meets the process requirements, whether there is any missing spray, and make up for it in time, and whether the spraying thickness is up to standard. 2. The finished rods should be packaged in green (bubble bags and blankets), the packaging joints should reach 30%, and then be reinforced with adhesive tape. Different types of rods should be distinguished with other colored tapes. 3. After packing, put them into the finished product area or special finished product area for neat stacking. 4. The package of accessories should calculate the required nuts, screws and the number of models and package them at the same time. 5. Measure the quality of the packaged rods and accessories, and calculate the tonnage of each batch of goods. |
 |
| Equipment Maintenance |
1. After each spraying, the remaining powder should be cleaned up in time, and the powder from the spray gun in the spray booth should be transported back to the warehouse to clean the spray booth. 2. The constant temperature room should be opened in time to check whether there are missing accessories. 3. The assembly line is refueled and maintained every half a month, and the pendants are stacked neatly for each time. |
