Selecting appropriate steps to refine the part's surface-based on its initial condition and specific processing requirements-to ensure a smooth, lustrous finish is a crucial stage in achieving a high-quality coating. Key equipment used in pre-treatment processes includes grinding and polishing machines, brushing machines, sandblasting equipment, tumbling machines, and various stationary tanks. Electroplating constitutes the core process of the entire production cycle. Depending on the part's specifications, one or more single-metal or alloy plating processes (such as electroplating or immersion plating) are selected to provide corrosion resistance, wear resistance, and an aesthetic finish.
Equipment utilized during the electroplating process primarily includes stationary tanks, barrel plating tanks, plating racks, and baskets. Post-treatment involves operations such as polishing, brightening, passivation, coloring, drying, sealing, and hydrogen embrittlement relief; specific processes are selected based on requirements to ensure the part meets quality standards. Common equipment for post-treatment includes grinding and polishing machines as well as various stationary tanks.
