Copper sheets and plates

Any device is only as reliable as the sum of its components. With more than fifteen years of experience in manufacturing tuned and detuned filter reactors for power factor correction, we are now offering our range of line reactors for application in power electronics. Same as with our capacitors, we focus on minimized power losses and maximum durability of the reactor – optimized for your application. Made of high-class transformer sheets and copper wire or aluminium band. Vacuum-impregnated with environmentally friendly, low-styrole resin for long operating life, high voltage strength and low noise levels. Standard terminals: copper terminal lugs, optional with screw-terminal blocks or cables. Integrated reversible thermal switch for monitoring of the reactor and control of external disconnection in case of overheating. Our standard range covers 400V 50Hz up to 300A per phase. Other values are available on request.

SURVOS products are optimally suited to sheet metal forming, machining and assembly technology. Our SURVOS has also been successfully used in cutting and punching aluminium sheets, steel sheets, copper and brass sheets, in cold profiling, bending, embossing, sawing and drilling aluminium profiles for decades. SURVOS detaches from a workpiece with 100% residue-free evaporation even when the parts lie flat on top of each other. Only selected raw materials of the highest purity are used for SURVOS. One of the main components is dearomatized hydrocarbons of the highest quality. As a metal processing medium that evaporates residue-free, SURVOS combines optimum lubricity with favourable values for evaporation speed, toxicology and environmental protection. All SURVOS products are classified according to REACH (EC 1907/ 2006) and do not contain any substance that is on the list of candidates for SOVHC.

SURVOS – 100% residue-free* evaporating metal processing oil. SURVOS Rapid D evaporates considerably faster than the "Standard" formulation (with a somewhat lower lubricity). SURVOS Rapid D impresses, however, with short evaporation times and is 100% residue-free*. The fluid is used in particular when operations follow each other in a short cycle sequence and no residue is allowed to remain. * According to the specifications of the DAB (German Pharmacopoeia), an evaporation residue of < 0.01% is considered to be residue-free.

Our high-performance machining oil SENTOS V-LR3 has a somewhat higher lubricity compared to our SURVOS products. This product also consists of volatile components that evaporate down to a lubrication residue of 3%. All components are approved according to USA-FDA §178.3910 as surface residues for the manufacture of food packaging. This makes our SENTOS optimally suited as a lubricant and drawing agent for punching and deep drawing (even with high contact pressures), for cutting and perforation of sheets (aluminium, steel, copper, brass, zinc-plated), including transformer and electric sheets, as well as for painted and coated sheets in particular. In addition, our SENTOS is especially well suited for cold profiling, bending and embossing, as a cooling lubricant for sawing, drilling, milling and engraving as well as a lubricant for cutting non-metallic materials.

The 20 kHz roll seam welding heads with up to 3KW power are particularly suitable for continuous welding of pipes, solar absorbers, or copper sheets. Thanks to the discshaped sonotrode, ultrasonic roll seams provide continuous welds without seam interruption.
