Struggling with slow bends, frequent setups, and rising labor? That friction drags throughput and profit. We help you fix it with a modern panel bender that makes bending simpler, faster, and more accurate.
A CNC panel bender is a machine that bends sheet metal automatically with precise, programmable motion. It uses a smart cnc controller, tools, and blades around the part to bend panels with speed and repeatability, raising productivity while lowering skill barriers and total cost.

STON — Sheet-Metal Automation & CNC Fabrication Equipment Manufacturer (OEM/ODM, Factory-Direct).
We serve sheet-metal job shops, cabinet makers, HVAC duct plants, appliance & kitchenware factories, telecom/power enclosure producers, lab/education equipment lines, EV charging enclosures, metal furniture & racking, system integrators, distributors/importers, and industrial automation partners.
We design for high precision, uptime, safety/CE-ISO compliance, energy efficiency, low TCO, customization, and rapid commissioning—backed by responsive after-sales and spares.
A panel bender is a panel bending machine that uses automated blades to bend flanges up or down around a stationary blank. Unlike conventional brakes, the tool wraps the metal, so results are repeatable even with operator changes. It’s ideal for sheet metal boxes, doors, covers, and frames where precision and efficiency are crucial.

With a PB, you automate more bends, reduce regrips, and stabilize angle across thickness variations. This boosts productivity and trims scrap.
The Panel Bender perfectly meets the door and window industry’s demand for customized, high-quality, and high-efficiency production through its high-precision, flexible, and automated processing capabilities. It not only solves the pain points of insufficient precision, cumbersome mold changes, and high labor costs in traditional bending processes, but also provides key support for the digital and intelligent transformation of door and window companies, helping them to improve product added value and delivery capabilities in the fierce market competition (such as high-end home decoration and commercial building doors and windows).
Digital management, adapting to the intelligent manufacturing upgrade of the door and window industry
The intelligent flexible bending center can be connected to the MES (manufacturing execution system) or ERP system of the door and window enterprise to realize real-time interaction of


The main frame carries the clamping beams and forming blade. STON designs for durability, rigidity, and state-of-the-art motion. This high-performance hardware plus smart automation keeps angles stable even when material lots vary.
Excellence here means top quality bearings, guides, and drives, sealed against dust, and designed for superior performance over years of shifts.
You want faster bends and steadier quality.
With a STON panel bender, your team runs more parts per shift with less training, fewer reworks, and easier adjustment across lots and thickness.
Let us tailor the solution to your parts and budget. We’re the supplier that listens, engineers, and supports.
“We moved box doors to the PB. Cycle time dropped 35%. New staff reached target angles on day one.” — Plant Engineer, Cabinet Factory
What types of sheet metal can your flexible bending center process? What is the thickness range?
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.
After purchasing the machine, do you provide installation, commissioning, and operator training?
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.
Can you provide customized solutions for special needs?
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.
What is your after-sales response time in the event of a malfunction? How do you provide technical support?
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.
Whether you're upgrading an existing line or starting a new project, STON will customize a CNC solution for your production.
