The flat side polishing machine uses a combination of abrasive belts, wheels, and compounds to achieve the desired finish. Advanced models can automatically adjust to different workpiece dimensions and surface conditions, delivering high-quality results with minimal manual intervention.

This machine is used to polish the sides of the sink bowls, providing a uniform finish around the perimeter. Polishing the sides is crucial for both the appearance and the functionality of the sink, ensuring there are no rough edges. The side polishing machine is equipped with precision guides and adjustable heads to ensure consistent contact with the workpiece. This ensures that the entire side surface is polished evenly, enhancing the overall quality and appearance of the sink.

This machine focuses on polishing the bottom side of the sink bowls, ensuring they are smooth and free from defects. A polished bottom side enhances the overall quality and durability of the sink. The bottom side polishing machine is designed to handle various sink shapes and sizes, with adjustable fixtures to hold the workpiece securely during the polishing process. High-performance motors and abrasive tools ensure efficient material removal and a superior finish.

This comprehensive polishing machine handles both the inside and outside surfaces of the sink bowls, ensuring a complete and uniform finish. It guarantees that the entire sink has a consistent appearance and quality, enhancing its marketability. The machine's dual-action polishing heads can be independently controlled to achieve optimal results on different surfaces. Automated loading and unloading systems further enhance productivity, making this machine an essential component of a high-efficiency production line.

This cleaning line uses spray nozzles to thoroughly clean the sink bowls, removing any residual oils, dirt, or debris from the manufacturing process. Cleanliness is critical before further processing and final packaging, ensuring the sinks are ready for use. The hanging type cleaning line allows for continuous processing, with sinks moving through various cleaning stages suspended from a conveyor system. High-pressure spray nozzles and detergent solutions ensure thorough cleaning, while rinse and drying stages prepare the sinks for further processing.

The ultrasonic cleaning line uses high-frequency sound waves to clean the sinks, providing a deeper and more effective cleaning process. Ultrasonic cleaning ensures that even the smallest particles and contaminants are removed, which is essential for maintaining the quality and hygiene of the sinks. This method is particularly effective for removing stubborn residues and particles from complex shapes and hard-to-reach areas. The through-type design allows for continuous processing, with sinks passing through multiple ultrasonic cleaning tanks, rinse stages, and drying stations.

The molds are used in the deep drawing process to shape the metal sheets into the desired sink forms. High-quality molds are essential for producing sinks with precise shapes and dimensions, ensuring consistency across production batches. Molds must be carefully designed and manufactured to withstand the high pressures and stresses involved in the deep drawing process.
