The aim of the strategic partnership is to offer to customer the strengths and advantages of the two industrial entities Pivatic Oy and RAS Reinhardt Maschinenbau GmbH and to strengthen both competitive position in the sheet metal machine tool markets. For Pivatic the co-operation with RAS brings wider product offering and higher flexibility for bending solutions specially with small and medium size volumes in sheet metal manufacturing.
RAS Reinhardt Maschinenbau GmbH and Pivatic Oy has been announced a strategic partnership. Both RAS bending centers and Pivatic punching systems have been known and established on the sheet metal machine tool market for decades. In the new cooperation model, the two companies contribute their know-how in punching and bending and offering lines for their customers as a joint solution.
With the unique Pivatic-RAS solution, two sheet metal processing technologies are integrated in a single production line: coil feeding or sheet punching by Pivatic and bending by RAS. Compared to other traditional systems, the material only moves once through the Pivatic punching line and the result is a punched part that is produced faster than any other traditional solutions.
This punching speed in combination with the bending speed and flexibility of the RAS bending centers leads to an automated flexible production solution that is characterized by low cycle times, high productivity, low logistics and handling costs, high design freedom in part construction and low costs per part.The integrated line is very compact and requires only a minimum of floor space. Due to the flexibility of both technologies, this modular line is suitable for large production batches as well as for small and medium quantities.
The punching process can start from sheets or from coils. The Pivatic punching machines can process coils from the width of 60mm up to 1825mm and from the sheets from 200mm up to 1825mm. Pivatic additional cut-to-length (CTL) and cut-to-length (CTW) integrated shears deliver precise and long cuts for the bending process. The RAS bending module can consist of one of the three bending centers with maximum working lengths of 2160mm, 2560mm and 3060mm. After bending, the finished panels can be forwarded in subsequent lines as automatic welding or stacking.
The control system software organizes the data communication to the machines of the production line, send information to an ERP system and creates statistical data. State-of-the-art technology meets industry standard 4.0. The programming of the punching and bending processes is based on 3D and 2D CAD drawings can also be carried out automatically.
The list of benefits of the common solution is long. The direct linking between the main processes reduces the logistical effort and improves the material flow, which has an economic impact, especially in the case of large components with small quantities. As a result of the linking, a finished bent product is always created after one pass and no stock of semi-finished products accumulates between punching and bending. The automated processes reduce human intervention and possible errors or damage during handling.
The largely synchronized processes during punching and bending increase throughput and efficiency, which ultimately also leads to lower part costs. Since up to 120 punching tools are accessible at the same time during punching, there are practically no tool change times. The challenging scrap skeleton handling is also eliminated with this approach.
At the RAS bending center, the punched blanks are automatically turned if necessary and then loaded, aligned, positioned, bent and unloaded. Automatic tool set-up and bending up and down without turning the part are an important matter of course. The automatic bending sequences ensure maximum precision and repeatability, which is also suitable for laser welding. Bending without damage to the surface of the material and without tool wear are outstanding properties, especially in stainless steel applications.
Pivatic, based in Finland, was founded in 1975 and is part of the Ursviken Group. Over 450 sheet metal processing systems are convincing proof of the efficiency in automatic punching.
RAS looks back on more than 80 years of experience in sheet metal processing and completes the systems with its bending centers.
