inside surface coating method of pipe line for mold cooling |
| abstract |
The present invention cleans the inner surface of the cooling water line of the mold with high-pressure washing water to remove the gun drill processing chips and oil generated during the processing of the gun drill equipped with the cooling water line, and prevents the internal weakness of the coating film due to the oil by the sanding process. It removes sludge and foreign substances inside the cooling water line of the mold, prevents corrosion resistance and foreign substances from being adsorbed on the cooling water line inner surface of the mold by the coating process, and improves the corrosion resistance and hardness of the cooling water line inner surface of the mold by the heat treatment process. Because the flow of cooling water can always be made easy and constant when manufacturing products using molds, defects caused by the inability to flow cooling water, as well as sludge accumulation or corrosion on the inner surface of the cooling water line of the mold Disclosed is a method of coating the inner surface of a mold cooling water line so that it can be prevented in advance. |
