The plate turning machine is mainly used for metal plates (such as cold-rolled steel plates, stainless steel plates, aluminum alloy plates, etc.). While achieving plate posture adjustment (flipping, positioning), it also completes the bending process simultaneously. It is widely used in metal processing scenarios such as automotive parts, home appliance casings, and furniture production.

Suction-cup feeder and heat-treated knives handle various thicknesses with stability and control.
The automatic plate turning and folding machine keeps panel edges straight and folding angles consistent, even on long and thin parts. This reduces rework at the press brake, improves the fit-up of corners and joints and gives you neat, ready-for-welding panels for cabinets, doors, drawers and electrical enclosures.
The automatic plate turning and folding machine is specially designed for sheet metal processing—including cold-rolled steel, stainless steel, and aluminum alloy plates. It integrates flipping, positioning, and bending in one system, widely used across automotive parts, home appliance enclosures, and metal furniture production. Below are the key components ensuring its performance and reliability:
Welded with 80×80×3mm thick square tubing, the bracket and feeding mechanism adopt an integrated structure. All frames are annealed and precision-machined using STON’s own floor-type boring and milling machines, ensuring rigidity and accuracy during panel handling.
Crafted from hardened high-quality steel, the folding knife withstands repeated bending stress and friction. Its quick-change design makes maintenance and blade replacement easy, while the secure drive shaft connection guarantees folding accuracy throughout the flipping process.
The system features a human-machine interface (HMI) with a large digital display. With multi-axis synchronization and advanced algorithms, it provides precise compensation, fast turnover speed, and user-friendly operation—even for first-time operators.
Copper tubing delivers lubricant to each friction point. These corrosion-resistant tubes ensure smooth motion, reduce wear, and extend the lifespan of key moving parts, optimizing performance over long production cycles.
Equipped with high-strength rubber suction cups, this device ensures stable, non-slip feeding. The layout is optimized based on material size and weight, preventing misalignment or material drop during the flipping and loading process.
The cabinet air conditioner controls the temperature and humidity within the control cabinet of the panel tilting machine, ensuring the proper functioning of the electrical components. It operates over a wide temperature range, from -20°C to 55°C.
Built from high-strength steel and precision heat-treated, the press knife adapts to various material thicknesses. Lead screw-based vertical adjustment ensures accurate, consistent pressure during the bending process.

Our machines is suitable for common sheet metals such as stainless steel, carbon steel, aluminum alloy, and galvanized sheet. The thickness range is 0.2mm-6mm, meeting needs of various industries, including home appliances, hardware, and cabinets. It also supports asymmetric and complex customized processes.
Yes, we offer a one-stop service: “on-site installation + commissioning + customized training.” Professional engineers will visit the customer’s site to complete production line assembly and equipment integration commissioning to ensure the line reaches its designed capacity. We also provide theoretical and practical training for operators (6-8 days), covering equipment operation, routine maintenance, and troubleshooting. After the training, we provide an operator manual and video tutorials.
Customized services are available. We will optimize the machine structure based on the customer’s workshop space, load capacity, and processing requirements. While ensuring processing accuracy, we adapt the machine to the shop’s existing power and air supply conditions to ensure smooth installation and efficient operation.
We have established a 24-hour global after-sales response mechanism: Customers can submit troubleshooting reports via phone, email, or online customer service, and a preliminary solution will be provided within 1 hour. If remote debugging is required, an engineer will provide video guidance within 2 hours. For hardware repairs, domestic customers will receive a visit within 48 hours, while overseas customers can use authorized service centers or expedited delivery of parts (with installation instructions) to ensure a quick resolution.
All of our standard equipment (flexible bending centers, CNC turret punch presses, press brakes, and punching and shearing machines) comes with a one-year free warranty. For some products with higher system complexity, the warranty period can be extended to 18 months. The warranty covers repair and replacement of quality issues with core components (such as servo motors, CNC systems, and guide rails), as well as free on-site inspections during the warranty period. Please note that equipment failures caused by human error, force majeure (such as floods and earthquakes), or failure to follow the maintenance manual are not covered by the free warranty, but paid repair services are available.
Extended warranties are available, with coverage ranging from 1 to 3 years. These plans are customized based on the equipment type, frequency of use, and customer needs.

A CNC Sheet Metal Folding Machine is an automated system that uses computer numerical control (CNC) to accurately bend and fold metal sheets at various angles. It replaces traditional press brakes in many applications, offering higher precision, repeatability, and faster setup times. Ideal for panels, cabinets, and enclosures, it’s widely used in industries like automotive, appliances, and furniture.
STON’s CNC folding machines support a wide range of materials, including cold-rolled steel, stainless steel, aluminum alloy, galvanized sheets, and more. These machines are engineered to handle different sheet thicknesses while maintaining high bending precision and minimal surface damage.
Compared to a traditional press brake, an automatic CNC sheet metal folding machine offers:
Faster setup and changeovers、Higher bending accuracy and repeatability、Reduced operator skill requirements、Safer operation with fewer regrips
It’s a preferred choice for batch production and panel forming lines requiring consistent quality and automation.
Yes. Our CNC folding machines are designed to support custom panel dimensions, with multi-axis linkage and intelligent control systems that enable complex bends, radius folds, and multiple angles in a single cycle. It’s suitable for both standard and custom sheet metal parts.
Industries that rely on high-precision metal panels benefit greatly, including:
Automotive part manufacturing、Electrical enclosures and cabinets、HVAC systems、Furniture and home appliance casings、Sheet metal job shops
These sectors value CNC folding for its efficiency, consistency, and adaptability to high-mix low-volume production.
It is mainly used for cabinet doors, side panels, drawer fronts, electrical enclosure covers, elevator panels and other large thin sheets that require accurate folding and safe turning around the press brake.
Yes. Our engineering team can evaluate your current equipment and layout, then design a suitable plate turning and folding solution, including communication signals, safety interlocks and material flow.
In most cases, one operator is enough to supervise feeding, program selection and finished part stacking, replacing several manual workers who previously needed to flip and handle large panels.
Whether you're upgrading an existing line or starting a new project, STON will customize a CNC solution for your production.
