State-of-the-art technology and extensive knowledge in the processing of steel characterise our location in Bad Salzungen, Germany. For us, performance means a wide range of cold-rolled steels of the highest quality at competitive prices, flexibility and a high degree of readiness to deliver while adhering precisely to the specified chemical and mechanical values. Surface finishing by electrolytic galvanizing and/or subsequent customisation of your goods are possible for us. We offer all our customers spooled materials with volumes of over 200,000 metres of metal strip per spool. This further development means a considerable advantage for our customers. Personnel-intensive set-up times and machine downtimes are avoided.

This material group comprises C-steel with low carbon content, good formability and fineblanking quality. Due to case hardening, the components have low-wear surface layers with high hardness and sufficient toughness in the core. They thus combine numerous properties and application possibilities in a wide variety of industries. To increase the wear resistance, you can also carburize or carbonitrate partial areas. C 10 E, C 15 E /➔ according to DIN EN 10132 - 2 Depending on the customer's requirements, we supply treatment states from soft annealed to high cold solidified.

This coating system is mainly used for the coating of cold rolled strip, but can also be applied to other metals. It is applied in the last processing step and enables a special gliding ability and heat resistance on coated surfaces.

In our new production space, we have at our disposal 30 state-of-the-art automated punching & bending machines. In addition to bent wire parts, we also produce bent strip parts here. Production to order with complex forming: Bent strip parts are produced from a broad range of materials, including for instance stainless steel, alloyed or carbon steel, brass, copper, bronze, or even K55 or K75, a specially alloyed steel. We produce complex forms and assembly parts with a strip thickness of 0.15 to 3.00 mm and with a strip width of up to 120 mm; the strip thickness will be dependent on the material. Strip materials: Carbon steels, Stainless steels, Cold-rolled strips, Slit strips. Non-ferrous strips: Brass, Copper,Bronze,Special alloys such as K55 or K75. Strip coatings: Tin-plated, Galvanised, Silver-plated, Gold-plated, Painted, Partial coatings, Special coatings on request.

Cold rolled steel sheets are produced by re-rolling process of hot rolled steel sheets in order to provide precise thickness distribution across the coil. The surface roughness of the cold rolled materials is lower compared to hot rolled steels and suitable for painting and coating applications. According to the customers demands, it can be supplied in coil, slitted and cut to length sheet form. Our stock includes cold rolled steel sheet materials produced according to EN 10130, EN 10268, EN 10338, EN 10209 and others.

Cold rolled steel is low carbon steel produced by a "cold rolling" process and processed at near normal room temperatures. Cold rolled steel offers superior strength and machinability. Cold rolled steel sheets are often used for engineering products where close tolerances, concentricity, surface smoothness and coated surfaces are required.

Self-adhesive magnetic strip for holding documents. On a roll to be cut individually to size. • Self-adhesive magnetic strip for attaching documents and notes. Can be cut Individually to size • Low space requirement due to winding on a roll (diameter approx. 22 cm) • Self-adhesive fastening allows a uniform appearance on smooth, attachable surfaces such as cabinets, glass doors and shop windows as well as on whiteboards, lean cubes and showcases • Residue-free removal from smooth, attachable surfaces • Hold documents on the side or the top depending on the available space

The new standard for precision and speed With the new VTLG Series laser systems, Vollmer is giving strip thickness measurement new impetus: They combine the highest precision with rolling mill-oriented design. Thanks to their unique measuring method, they are suitable for use in cold rolling mills. With a measuring precision of ± 1 µm and scanning rate of up to 80 kHz, they offer the precision and speed necessary for the control of the strip thickness. VTLG systems are the only laser gauges to measure the strip thickness during rolling in the mill, thus opening up completely new possibilities in production and quality assurance for our customers. As with our contact gauges, they measure the thickness irrespective of the alloy – ideal preconditions for use in the rolling mill, but also on the annealing line, in the finishing section, on the strip edge miller or in the steel service centre.

Precise even with low strip tension The segment rolls were developed specially for use in stretch bending levellers. The extremely free-running measuring rings permit high-precision shape measurement even with very low strip tensions. A rigid tubular section which forms the shaft of the roll supports several pivotably mounted measuring rings. They form the outer shell of the measuring roll over which the strip passes. Force sensors inside the measuring rings detect the force resulting from the strip tension. The sensors have high resolution, are overload-proof and maintenance-free. The data are transmitted through the centre axis of the roll and output as a Profibus signal.

VGraph is the software package for the recording and visualisation of data with extensive statistical data evaluation options. It synchronously records up to 16 measurement values – for example thickness, width and speed of the strip, rolling force or strip tension – on a production line, stores them and evaluates them statistically. With statistical functions such as histograms, Cp and CpK values and error lists, VGraph provides valuable decision aids for the evaluation and further use of the coil produced. The diagnostic instruments allow optimisation of the rolling process and the line engineering. The optional FFT analysis detects periodic fluctuations in the strip thickness. VGraph meets the needs of day-to-day strip production. One example: Random lengths of strip at the leading and trailing ends (drop-off) can be suppressed – even subsequently – in the statistical evaluations.

In addition to the strip speed, VRecoS also records up to three further tracks, such as the rolling force or the strip thickness at the ingoing and outgoing ends of the mill. The measurement protocols can be stored, printed out and distributed by e-mail. The measured values are recorded as a function of length. The recording frequency can be set with a scanning rate of 2 ms. Random lengths of strip at the leading and trailing ends (drop-off) can be suppressed, even subsequently. The signals are recorded using a data collector belonging to the scope of supply. Its electronics with input and output modules is designed for installation in switch cabinets or desks in interference-proof 24 Volt top-hat (DIN) rail technology. It transmits the data via a network cable to the Windows recording computer which can be supplied by Vollmer or by the customer.

The high-speed servo-hydraulic control of the mill screwdown closes the loop: The thickness values measured precise to the micrometre form the basis for quick and precise control. Vollmer offers solutions for all control concepts from simple feedback control through to complete mass flow control or Direct gap contol for rolling of wedge-shaped strip and in tandem mills. Vollmer supplies the complete control system – from the sensors through the control technology right up to the hydraulics and the cylinder – from a single source. For our customers that means having just one contact partner – in short: A one-stop solution.
