In most cases, blackening treatment on steel, also known as black oxidation, can enhance corrosion resistance to a certain extent. However, the protective effect remains somewhat limited. To significantly improve both corrosion resistance and lubrication of the blackened layer, additional measures like oil immersion or subsequent rust prevention treatment are still necessary.

Defects are bound to occur during the reprocessing of mechanical equipment or metal parts. As a result, the final step of surface treatment holds significant importance. It serves the dual purpose of enhancing the aesthetics and protecting the surface, ultimately improving the performance of metal components and preventing rust.

In today’s rapidly developing machining industry Precision Machining has made tremendous advances, especially in the area of smart manufacturing. With more than three decades of metal machining experience, and staying abreast of latest developments across a multitude of industries, World Known Precision Industry (Taiwan) Co., Ltd. (WKPT) has become a leading manufacturer of components in the transportation, construction, agriculture, green energy, and semiconductor industries.

Defects are bound to arise during the reprocessing of mechanical equipment or parts related to metal. As a result, the final item's surface treatment process plays a crucial role, serving the dual purpose of enhancing aesthetics and providing protection. This process not only improves the performance of metal parts but also helps prevent rust.

Metal fabricators aiming to venture into finishing processes should familiarize themselves with two prevalent options—liquid and powder coating—along with the prerequisites necessary for a company seeking to employ either or both.

Over the past few years, plastic electroplating has gained widespread popularity, particularly in the decorative electroplating of plastic components. Among the various types of plastic utilized in electroplating, ABS plastic stands out as the most extensively employed.
