PRÄZI is a group of companies in the supplier industry and offers custom-made solutions for applications in machine tools, mechanical engineering, automation engineering, robot technology, in the conveyor industry and the agricultural machinery industry. With over 650 employees, innovative products with the highest utility value are made at 5 sites in Europe based on customer requirements. At the main production facility, precision flat steels in standard and special design as well as guide bars and slide rails in differentiated geometrical cross-sections are produced.
PRÄZI-FLACHSTAHL AG offers precision flat steel according to DIN 59350 as well as tool steels with a machining allowance protected against corrosion in partial lenghts of 500 and 1030 mm. All qualities are machined on all sides and at a right angle, with guaranteed decarbonisation free surface. Our extensive stock includes more than 6500 dimensions in 14 grades of material (1.2842 1.2436 1.2379 1.2767 1.2363 1.2343 1.2311 1.2312 1.2162 1.2085 1.1730 1.0570 toolox 33 toolox 44) and guarantees the shortest possible delivery times. Special dimensions and alternative steel qualities are available at short notice.
The PRÄZI Flat Steel AG prides itself with extensive know-how in the production of high-precision guide rails, sliding rails and roller conveyors. Hardened guide bars are manufactured according to DIN 69056 or customer requirements, in lengths up to 6000 mm. Other core competences lie in the construction, development, production and component assembly of wearing plates and tools for the sand-lime brick industry and the concrete industry.
At the Everwinkel site as well as within the subsidiary UNIEMETAAL B.V., Netherlands, we are manufacturing complete tools for all common press types as well as single sub-assemblies such as upper- and lower stamps, moulding tables, moulding frames and peripheral components. The consultation and solving of customer-specific requirements, modifications, refitting, repairs and special orders is carried out by competent and experienced employees. Multiple wearing parts such as horizontal boards, face plates, stamp plates, cover plates as well as form prisms, base grips and mandrels are manufactured in-house completely. Through the use of the most modern hardening technologies the wear resistance of the materials - and thus also the service life - is improved. The PRÄZI-FÖRDERTECHNIK GMBH manufactures extremely wear resistant coated conveyor screws, continous rolled spiral sheets, ready-to-install complete conveyor screws and spirals made of flat steel and round steel. These products are used everywhere where granular, powdered or viscous materials need to be promoted.
Since 2001, the PRÄZI-Fördertechnik delivers feeding systems for biomass and, with more than 1,500 installed plants, belongs to the leading suppliers. Our standard screw system in combination with vertical mixers is build out of the following components: Feed screw, steep conveyer screw and the stuffing screw. It is being delivered to comply with the ATEX- directive and is useful for small and medium-sized biogas plants. In large systems, the feeding system is used in combination with a moving floor up to 250m3 in capacity. To complement the medium-sized systems, PRÄZI has developed the compact sliding floor. Besides the integrated conveyor screws, a crushing screw has been installed, which enables even difficult substrates to be supported. The compact sliding floor can optionally be equipped with a continuous weighing, with which a formulation is made possible when filling. In close cooperation with well-known manufacturers of agricultural machinery, the PRÄZI Group produces rotating structural components for the agricultural machinery industry. The products are fabricated for combine harvesters, beet harvesters, harvesters and harvesting attachment devices at the two sites in Germany and subsidiaries CONTAREX Agrotechnika Kft in Hungary. Intake drums, threshing drums, turning drums, feed drums, finger rolls and conditioner, guide rollers, rotors and impellers are the most modern manufacturing facilities that are being produced.
A successful quality management in the individual companies in the PRÄZI is ensured in accordance with the DIN EN ISO 9001 and DIN EN ISO 9004.
