Boost Your Production Efficiency with Reliable, Customizable Automatic Loading & Unloading Systems.
Our CNC automatic loading and unloading systems combine robotic arms with bending centers or press brakes to enable unmanned, high-precision, and flexible sheet metal processing. High-accuracy positioning removes manual errors, keeps batch quality consistent, and adapts quickly to multi-variety, small-batch production. One system can replace 2–3 operators, boost daily output by 3–6 times, and significantly improve on-site safety while reducing labor costs.
Each Automatic Loading & Unloading System can be customized to your sheet size, stack height, and layout requirements, and integrated with panel benders, press brakes, turret punch presses, or laser cutting lines.
Our Automatic Loading & Unloading Solution – combining the STON truss system with the Bronte robotic arm – automates sheet picking, loading, unloading, and finished-part stacking around the bending center. It handles large panels, long parts, and multi-bend components commonly used in cabinets, enclosures, racking systems, and home appliance panels, delivering repeatable accuracy and clean stacks ready for downstream welding or assembly.
We believe in building strong, transparent relationships with our clients. That’s why we invite our partners to visit our state-of-the-art manufacturing facility and see our production process up close.
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 one-year extension for a single device costs approximately 3%-5% of the total price, while bulk extensions for multiple devices or fully automated production lines offer a 20% discount. During the extended warranty period, in addition to core component repairs, customers also receive a free annual comprehensive equipment inspection and maintenance service to help them proactively identify potential faults and extend the life of their equipment.
We offer flexible payment options to meet the needs of domestic and international customers: ① Telegraphic Transfer (T/T): 30% prepayment, 70% before equipment leaves the factory; ② Letter of Credit (L/C): We accept irrevocable letters of credit issued by the customer’s partner bank at sight to ensure the security of funds for both parties. All payment methods comply with international trade practices and support mainstream settlement currencies such as the US dollar and the euro.
Yes. Our robotic and truss loading & unloading systems are designed to work with both STON equipment and third-party panel benders, press brakes, turret punch presses, and laser cutting machines. After you share your machine models, control interface, and layout, our engineers will evaluate the compatibility and provide a retrofit proposal, including gripper design, safety guarding, and cycle-time estimation.
To design a complete solution, we usually need your part drawings, sheet size and thickness range, material type, target takt time, daily output, stacking height, and the machines you want to link. Based on this data, we will propose a layout, robot or truss configuration, gripper design, and a detailed quotation.
Whether you're upgrading an existing line or starting a new project, STON will customize a CNC solution for your production.
