In fact, they are the most expensive part of the hydraulic plate roll, and it takes a very long time to be replaced, causing important production stops (for larger rollers they could even take up to a few months). Many manufacturers of hydraulic plate rolls (especially the smaller ones) use rolls obtained from drawn round steel bars, to save on the cost of the roll. However, laminated round steel products have much problems: There are often porosities in the steel, which can lead to the initiation of fatigue cracks, with consequent cracking of the roller. The crystalline grains do not have a precise orientation, and therefore have less resistance capacity. Lower compactness of the roller which translates into lower toughness and lower impact and compression resistance WHY CHOOSE US FOR THE PRODUCTION OF ROLLS FOR HYDRAULIC PLATE ROLLER MACHINE This is why Sertom manufactures rollers for plate rolling machines only from forged pieces, with a high reduction ratio of the starting ingot. The most used material for our rollers is 42 CrMo4, but the material is chosen according to the customer's needs. In fact, high-strength steels are often used, such as 40 NiCrMoV 16KU and 65 MnCrMo4 for hot plate rolling. After forging, the piece is roughed on the lathe and subsequently the quenching treatment (hardening and tempering) and finishing on the lathe. Hardening is a very drastic process and for large pieces it can lead to internal tensions, both thermal and structural. Therefore, the tempering phase after hardening is a fundamental phase for the correct production process of the roller, because it ensures a good compromise between hardness and toughness. The quenching heat treatment is carried out after the roughing of the roller, to allow the hardened layer to go deeper. This process guarantees excellent performance of the hydraulic plate rolls for its entire useful life.

Their workshop is located in a strategic point, the industrial area of San pietro Mosezzo (NO), 50 km far away from Milano (IT) They were looking for a solid, simple and reliable machine to bring this activity back into their company which so far has been completely left to external suppliers, in order to allow them to give the right production autonomy in a market where delivery terms are increasingly restricted. They needed a special plate rolling machine with very specific features: The machine had to roll 50 mm over 3000 mm width; The software had to have a friendly user interface, but at the same time the customer wanted to be able to do a very intuitive check if the machine had any electrical or electronic problems; The machine had to be designed without any requirement of foundation pit; After a careful market research, Sertom PB has been their favorite supplier of this very special plate rolling machine, they recognized that our machines are very strong, very heavy and ensure greater reliability in the main components if compared to other competitors. Moreover, they preferred to work with a historical company and a family business, since they always try to establish a long-lasting collaboration relationship instead of a simple economic agreement that is advantageous but limited in time. --- Since 60 years SERTOM manufacture plate rolling machines for big corrugate plates. The first of these plate roll machines is a prototype ( because it was the first machine for so thick and strong corrugate plates ) for a canadian leading company in the production of bridges, steel structures, and corrugated pipes. This plate roll machine is still in production. All the 3 roller are motorized by hydraulic motor connected with a reduction gear. Thanks to the positive experience made in Canada, SERTOM has become the only manufacturer of corrugated plate roll machines for big thickness. We started the production of a large number of this type of plate roll machines for a group situated in Sweden and with approximately 30 companies on the whole european territory. The last of these plate rolling machines it was delivered to Russian Federation and produce a corrugated plate with the following characteristics: → MATERIAL: S355 J2 → THICKNESS: up to 12mm → AREA MOMENT OF INERTIA: Up to 120. 000 mm4 --- We are pleased to inform that since November 2019, SERTOM is a associate member company of UCIMU. The UCIMU mark is distinguishing sign of the most qualified production of the sector. Relating to the enterprise rather than the product the UCIMU mark is granted to associate member that can demonstrate: → Commercial reliability → Financial solidity → Maximum attention to safety and testing functions → Customer care ( following the key performance index method ) →Sustainable manufacturing All these qualities have been recognized in SERTOM and in our rolling machines. --- For an important costumer in the field of oxi – cutting, Laser – cutting and plate bending, SERTOM delivered a rolling machine with variable axis completely taylored and designed on costumer needs. Costumer specifications were very clear: → Avoid machine downtime as much as possible. → Use only top brands for commercial components. → Special training of one week for cones production. → Capacity of bending Stainless Steel. --- The correct definition of straight end is the follow: the straight end is the edge that remain straight ( or not curved to size ) on both the end of the plate. Is impossible obtain a straight end equal to zero, because for the geometric configuration and the way of operating of the rolling machines it would require an infinite high force. The flat end result to be the one of the most important parameters for choosing a rolling machine, infact the smaller is it, the greater the force required by the rolling machine, the diameter of the roller and essentially, the size of a rolling machine. --- --- ## Macchinari Versatile and efficient, the DEA 3R Plate roll Machine is a 3-rolls hydraulic machine with variable geometry and full pre - bending. The main feature that makes the DEA 3R the most versatile machine on the market is its particular geometry that allows it to work as a press brake or as a 4 pyramidal rollers. In fact, its lower rollers move horizontally, while the motorized upper roll makes a vertical movement. --- The DEA 4R is an extremely plate rolling machine. Its main feature is the movement of the side rollers on straight guides. Thanks to its structure and the high precision of the movements given by the technologically updated electronics, accuracy is ensured in the invitation and bending phases. All the operations of the machine are controlled by a state-of-the-art PLC and upon request it is An easy-to-use CNC control is also available. The ideal machine for mass production. --- DEA 3RS and DEA 4RS are plate roll machines technologically advanced, high efficiency, made with resistant and top quality materials.

A machine designed for the production of silos starting from a coils, customizable with the cutting and welding system. It is not a simple vertical Plate Bending Machine, but a much more complete machine. It is in fact made with a coils feeding system ( motorized), with the pre-bending rolls (to eliminate the spring back return of the coils) and the asymmetrical plate roll to obtain the desired diameter. Furthermore, the rolls must to lead the sheet metal to the pinch rolls in the ideal position for the bending, even when the coils are almost exhausted. To make this possible, one of the rolls is mobile and at the output the sheet is supported by a horizontal orientable roller. --- ---
