Automatic panel bender for versatile production
The P4 natively combines productivity, with its automatic bending and handling cycles, and flexibility, with its universal bending tools.
Product overview
The P4 uses universal bending tools which automatically adapt in-cycle to the panel geometry, without machine down times or manual retooling, allowing batch-one or kit productions.
The technical solutions adopted (Direct Drive and pneumatic and electric actuators) allow the P4 to respect both people and the environment without reducing its productivity.
The integrated adaptive technologies (advanced sensors, bending formula, MAC3.0) make the system intelligent and able to automatically adapt to changes in the material and the external environment, eliminating waste and corrections, and extending the range of products that can be made.
The proprietary LINKS, STREAM and OPS softwares establish communication between the system and the company departments involved in the production flow.
The P4 offers customized solutions, including auxiliary tools and additional devices for special geometries or different loading/ unloading solutions.
MAC3.0
MAC3.0 detects any differences in the mechanical characteristics of the material compared to their nominal value during the cycle, adapting the movements of the bending unit and the manipulator to compensate them.
Industry 4.0
Digital transformation and Industry 4.0 are key topics for staying competitive on the market. When adopted, they can implement and manage complex, integrated, highly automated high-performance systems, and can help to develop simple solutions that require no structural changes to the production layout, making the world of smart manufacturing much more accessible.
Batch one?
No problem
The P4 panel bender is equipped with universal bending tools which automatically adapt in-cycle to the panel geometry, without machine downtimes or manual re-tooling, allowing batch-one or kit productions and processing the whole range of thicknesses and machinable materials, from 0.4 to 3.2 mm.

Heavy gage?
No problemThe P4 panel bender is equipped with universal bending tools which automatically adapt in-cycle to the panel geometry, without machine downtimes or manual re-tooling, allowing batch-one or kit productions and processing the whole range of thicknesses and machinable materials, from 0.4 to 3.2 mm.
Made-to-measure modularity
P4 can be fed manually or automatically, picking the sheets up from one or more sheet metal packs and feeding the machine in masked time. P4 can also be equipped with different unloading devices, manual or robotized.
Intelligent system, constant quality
Practically everything you ever wanted to know about the P4 panel bender, satisfactorily explained.
Conventional bending is characterized by an average OEE of 30%, with flexibility dependent on the tool change system - which is often costly and more time-consuming than on a panel bender - or on the installation of more than one press brake. The P4 panel bender, on the other hand, natively combines productivity, with its automatic bending and handling cycles, and flexibility, with its universal bending tools. And with its advanced cycles, the P4 completes an average of 17 bends per minute.
The P4 panel bender doesn’t need re-tooling: the upper and lower blades, the counterblade and the blankholder are universal tools that are able to process the whole range of thicknesses and machinable materials.
With its 6 models available, Salvagnini offers the widest range of panel benders on the market today. Each of these models can be configured and customized with many options, to respond to many different production needs. After a feasibility study made on the key parts to be produced, Salvagnini can drive each customer in the choice of the most suitable panel bender, according to variables including production strategies, field of application, level of automation required for loading and unloading semifinished parts, options for achieving full versatility and, if necessary, types of auxiliary technologies such as cutting, punching and press bending, allowing the panel bender to express its productivity to the full
The P4 is equipped with an automatic blankholder, which automatically adapts the length of the tool according to the size of the part to be produced, without the need for machine downtime or manual re-tooling even in-cycle: the ideal solution for batch-one and kit production.
MAC3.0 is the set of integrated technologies – sensors, formulas and algorithms – that make the panel bender intelligent: it eliminates waste and reduces corrections, measuring in-cycle and automatically compensating any variability in the material being machined.
Each P4 panel bender integrates advanced sensors that measure the material thickness and the real size of the blank, and detects any deformations caused by variations in temperature. The data are fed in real time into the bending formula, which defines the correct force to apply to the sheet metal, guaranteeing the precision, repeatability and quality of the finished product.
In addition to the automatic blankholder, the P4 offers a range of options to guarantee maximum versatility and adaptability, to suit any production strategy or mix.
P4 is the ideal bending solution for flexible line or cell production. It can be equipped with proprietary OPS software, which ensures communication between the panel bender and the factory ERP: depending on needs, OPS manages the production of sequences of different parts. Universal bending tools, automatic in-cycle set-up and automatic handling allow the system to respond to any requests immediately.
The sheet metal is centered, just once at the start of the process, against controlled reference stops: this minimizes the cycle time as well as any precision errors, which are all absorbed by the first bend. The bending formula automatically optimizes the bending parameters to reduce waste, while MAC3.0 detects and automatically compensates any variability in the material to guarantee precise, high-quality bends.
Software
Industry has changed: flexibility and efficiency are fundamental requirements for managing increasingly smaller batches or rapid item turnover rate. And developments in technology have in some way upset the balance between workloads, with increasingly fast systems which however need to be guided by more and more specific machine programs, the generation of which is increasingly time-consuming. This is why software is increasingly crucial to improving the efficiency of machinery.
OPS is the Salvagnini modular production management software which optimizes the entire production process, exchanging real-time information between the machinery and the factory ERP/MRP.
Salvagnini’s IoT solution, increases the global efficiency of the panel bender. LINKS allows real-time monitoring of the machine’s performance and independent analysis.
