If the AC plug mold is not connected to water, it usually will not deform. Mold materials generally have good stability and high temperature resistance, and will not deform due to lack of contact with water under normal usage conditions. However, prolonged high temperatures, stress concentration, or improper storage and maintenance may cause mold deformation. If properly cooled during the injection molding process, it can help maintain the shape and accuracy of the mold. In general, regular maintenance and upkeep are necessary to extend the service life of the mold.
