To address this, modern sinks are designed with removable inner basins, allowing users to choose the appropriate inner basin based on the size of the items being washed.
[0003] In the current technology, basins within basins are basically made entirely of stainless steel. The current production processes include one-piece molding, roll welding, butt welding, and sheet metal bending and welding. Among these, one-piece molded basins have high requirements for raw materials and processes, resulting in higher prices. The other welding processes require welding and then grinding off the weld seams. Welding requires a lot of time, and if the weld seams are not handled well, it will affect the appearance. With long-term use, the weld seams are prone to falling off, which will affect the service life.
[0004] The demand for basins within basins is increasing in daily life, and the size requirements are also diverse. However, regardless of the process, each model of product basically requires corresponding production equipment for product feeding, flattening and positioning, polishing, production separation and labeling, which restricts the diversity of product size specifications and cannot meet the flexibility of market demand.
