II. Product Introduction
Automatic Sink Bottom Corner Pressing & Forming Machine (Model: SBCPF-800H)
Tailored specifically for the stainless steel sink manufacturing process, the SBCPF-800H is a specialized piece of equipment engineered to refine the critical bottom corner forming step—directly influencing the sink’s final height, structural stability, and water-tight performance.
In sink production, the precision of bottom corners directly correlates with the overall height consistency of the finished product. This machine addresses this key requirement by integrating automated pressing and forming functions, ensuring that each corner is uniformly shaped to meet strict height tolerances (±0.5mm). Its adaptive design accommodates various sink types, including undermount, drop-in, and farmhouse styles, with a focus on processing the right-angle or rounded bottom corners that determine how the sink sits in countertops and maintains its vertical dimensions.
Equipped with height-calibration sensors and adjustable pressure settings (800-3000N), the SBCPF-800H allows operators to program specific parameters based on the sink’s target height (ranging from 150mm to 500mm, suitable for most standard and deep-basin designs). The forming mechanism uses precision-machined dies to press and smooth corner seams, eliminating sharp edges, ensuring water flow efficiency, and enhancing the sink’s load-bearing capacity—critical for withstanding daily use.
Constructed with anti-corrosive stainless steel components to resist water and metal debris, the machine features a user-friendly HMI touchscreen for real-time monitoring of corner height, forming angle (85°-90° for optimal water retention), and processing speed (up to 30 sinks per hour for heavy-gauge steel). Safety features include infrared guards and automatic shutdown on height deviation, preventing defective outputs and protecting operators.
By streamlining the bottom corner forming process, the SBCPF-800H not only guarantees consistent sink height across production batches but also strengthens corner integrity—reducing post-assembly leaks and improving long-term durability. It is an indispensable tool for sink manufacturers aiming to elevate precision, reduce rework, and meet strict industry standards for both residential and commercial sink products.
