TECHNOLOGIES IN RÁBA’S MÓR PLANT
In our Mór plant, the pressing technology featuring automated and single-stroke eccentric and hydraulic presses is continuously upgraded. The automated presses (160t, 315 t, 400t, 630t) efficiently serve our automotive customers providing them with large-series of pressed passenger vehicle components.
The main types of single-stroke eccentric and hydraulic presses are the 25, 40, 63, 100, and 250 tons C-case eccentric presses and the 250-ton C-case hydraulic presses. These presses lend themselves to the production of small series of components, as well as of large-series not suited for automatic production.
The company’s development projects put a special focus on the use of automated pressing technology.
In our Mór plant, various automotive components are manufactured using manual and robot arc welding in a protective gas shield, as well as projection and spot welding. Serial products are manufactured using robot welding technology, in the optimised “Lean manufacturing” system.
The machinery in the factory are suitable for the spot welding of female screws, threaded bolts, disc to tube, as well as disc to disc. There are 19 manual spot welders, with a capacity of 52-182 kVA. The automated coordinate spot welders are used to manufacture large series of seat back rest frames for passenger vehicles.
In addition to the traditional manual welding technology, the Mór plant is also equipped with 18 robot welding cells, where back seat frames are manufactured currently. The 15, state-of-the-art twin-arm and 2 single-arm arc welding cells, as well as the 1 twin-arm 3D arc welding robot are of the Motoman type.
Tube bending technology
In the Mór plant, tube frames are produced for the seat frames of passenger vehicles and commercial vehicles. The plant is equipped with tube cutting, as well as CNC tube bending equipment.
Wire bending technology
The wire bending technology allows for the production of wire components of seat frames using 2 single-head (maximum diameter: 6 mm) and 2 double-head (maximum diameter: 8 mm) wire benders.
Cataphoretic painting is a surface treatment method widely used in the automotive industry, resulting in a durable, weather resistant coating on both external and internal components. The company can achieve a layer thickness of 10-25 µm, with a maximum submergence limit of 1,7 x 1,2 x 0,3 m, a maximum weight of 160 kg in painting iron and galvanised parts, with an operational time of 2 hours and 540 hours of salt spray resistance.
Cutting and sewing operation
The established capacities currently allow the cutting and assembly of some 300.000 passenger vehicle seat covers annually. The cutting equipment is capable of spreading textile fabrics of 1,80 m width maximum. The existing cutting capacity allows the cutting of 500.000 passenger car seat covers annually. Production takes place on traditional and automated sewing machines within the “Lean manufacturing” system. The sewing cells have been tailored to customer needs, thus each cell completes its work process within the same timeframe.
Powder coating is a surface treatment method used to create a special coating layer on metal surfaces. The company uses the technology to provide a coating on welded seat frames, using the following technological steps: pre-treatment, drying, powder coating in automated powder coating cabins, smelting. Powder coating technology is used by Rába to create layer thicknesses of 80-140 µm for the surface treatment of metal parts.
