Technical know-how in a nutshell – because we want to set new standards in the field of electrical fasteners for our customers and our own demands.
|Ampere||Unit of measurement of electric current. Amperes per mm² Current flow: Units of measurement for electromagnetism.|
|Coating||Most common processes for coating metallic components can also be used for copper base materials. Various pre-treatment processes are common for copper materials. The choice of processes depends on the surface requirements, often conditioned by the following machining processes.|
|Unbending||Unbending is the term used to describe the unbent state of a busbar that is required for the manufacture of a final product by bending.|
|Inverter||An inverter is an electrical device that converts direct voltage into alternating voltage. Along with rectifiers, DC voltage converters and inverters, inverters form a subgroup of power converters.|
|E-Cu||E-Cu or E-copper is characterised by its high conductivity and relatively high corrosion resistance.|
|Laminated expansion busbars||Copper expansion busbars consist of copper lamellae of 0.2 mm thickness and are pressure welded at the ends. Aluminium foils are made of 0.3 mm thick lamellae and are welded with solid connections under inert gas.|
|Thread former||The thread former can be used to machine cold formable materials, i.e. most metals. Tapping achieves a higher pull-out strength of threads in many materials than would be achieved with cut threads, due to work hardening and texturing. Thread formers must also be used when no chips are allowed to accumulate, e.g. because a workpiece is difficult to clean.|
|Busbar||Busbars are crucial components in high-performance battery systems and complete power distribution systems.|
|Voltage test||A voltage tester is an electrical testing device used to determine the presence, and in some voltage testers also the level, of AC or DC voltage on operationally live parts.|
|AC voltage||Alternating voltage is the name given to an electrical voltage whose polarity changes in regular repetition, but whose mean value over time is zero according to the standardisation. The curve shape of the voltage is irrelevant and is by no means bound to the sine wave.|
|Alternating current||Alternating current refers to electric current that changes its direction in regular repetition and in which positive and negative instantaneous values complement each other in such a way that the current is zero as a time average.|
|Contact resistance||The contact resistance, contact resistance or contact transition resistance is the electrical resistance of an electrical contact surface, for example between the contacts of an electrical switch.|
|Conductance||The electrical conductance is the reciprocal of the ohmic resistance and thus the characteristic value of an electrical component. It is not to be confused with electrical conductivity, a material constant.|
|Transform||According to DIN 8580, forming is one of the six main groups of manufacturing processes. The most important manufacturing processes in forming technology are rolling, open-die forging, drop forging, extrusion, deep drawing and bending.|
|Contact corrosion||Bi-metal corrosion according to DIN EN ISO 8044 is corrosion caused by the electrochemical reaction of two different metallic materials or other electron-conducting solids.|
|Ohm||Ohm is the derived SI unit of electrical resistance with the unit symbol Ω (capital Greek omega).|
|Surface finish||The quality of a surface is standardised. Surfaces that can be measured are the ACTUAL surfaces. These can vary greatly depending on the manufacturing process.|
|Heat shrinkable tubing||Heat shrinkable tubing is a thermoplastic tube that contracts radially when exposed to heat. Heat shrink tubing is used for insulation, mechanical protection or sealing.|
|Transformer||A transformer is a component of electrical engineering. It usually consists of two or more coils, which are usually wound from insulated copper wire and are located on a common magnetic core.|
|cold forming||During cold forming of a metallic material, the number of dislocations increases considerably. The movement of the dislocations is hindered by their high number and obstacles such as a grain boundary. This does not result in a permanent change of shape, but the strength of the material increases while the toughness decreases. Further cold working requires more force to be applied; cold working ends when work hardening has increased so much that either the required force can no longer be applied or the material cracks. Work hardening can be reversed by recrystallisation annealing.|
|Quality||EMS quality management is certified according to ISO 9001. With CE, RoHS and UL certification, we also give top priority to environmental protection and safety.|
|Voltage||The electrical voltage is a fundamental physical quantity in electrical engineering and electrodynamics. Its formula symbol is the U. It is specified in the international system of units in the unit volt.|
|Phase||A phase or outer conductor is a conductor that is live during normal operation and can contribute to the transmission or distribution of electrical energy, but is not a neutral conductor.|
|Disconnector||A disconnector, also called an isolator, is an electrical high-voltage switch without a requirement for switching capacity, but with a clearly visible switch position.|
|Electrical contact||In electrical engineering, an electrical contact is used to establish an electrical connection between electrical components, between or within circuits or within components such as contactors, relays or pushbuttons / switches.|
|Cu-ETP||Cu-ETP is an oxygenated (tough-polarised) copper produced by electrolytic refining, which has a very high conductivity for heat and electricity (min. 57 m Ω-1/mm2 in the soft state).|
|Insert nut||Insert nuts have a mostly toothed collar that is pressed into a hole in the sheet metal. The screw is screwed in from the back. The serration of the collar dug into the sheet metal absorbs the tightening torque.|
|Shunt||A shunt, also called a shunt resistor or shunt resistor, originally refers to an electrically conductive component that is connected in parallel to a part of a circuit in order to divert an electric current from that part.|
|Direct current||Direct current is an electrical current whose instantaneous values of current intensity do not change over time.|
|CNC machines||CNC machines (Computerised Numerical Control) are machine tools which, through the use of control technology, are capable of automatically producing workpieces with high precision, even for complex shapes.|
|Electricity||Electric current, often just current, is a physical phenomenon of electricity. In the everyday meaning of the term, it refers to the transport of electrical charge carriers, for example electrons in conductors or semiconductors or ions in electrolytes.|
|Spinal sintering||Fluidised bed sintering is a widely used powder coating process to apply plastic coatings to metal surfaces. In this process, plastic powder is evenly applied to a heated metal surface through a fluidised bed. The melting of the plastic creates a dense coating.|
|Powder coating||Powder coating or powder painting is a coating process in which an electrically conductive material is coated with powder paint. A typical coating system consists of surface pre-treatment, intermediate drying, electrostatic coating zone and dryer.|
|Bi-composite-material||Bi = two composite = a material made of two or more joined materials.|
|Insulator||An insulator is a component used in electrical engineering and power engineering to fasten, hold or guide bare electrical conductors without any significant current flow through the fastening element.|
