The forming process is most often used to shrink or expand cylindrical tubing, but it can also form sheet metal by repelling the work piece onto a shaped die at a high velocity. High-quality joints can be formed, either by electromagnetic pulse crimping with a mechanical interlock or by electromagnetic pulse welding with a true metallurgical weld.
The material is often cross-linked through the use of electron beams, [6] peroxides, or moisture. This cross-linking creates the memory in the tubing so that it is able to shrink back to its original extruded dimensions upon heating, producing a material called heat-shrink tubing. For outdoor use, heat-shrink tubing often has a UV stabiliser added.
This is part of the electrical induction process, and is an example of the related "Faraday's ice bucket". Also, the idea of bringing small amounts of charge into the center of a large metal object with a large net charge, as happens in Kelvin's water dropper, relies on the same physics as in the operation of a van de Graaff generator .
The process for miniaturizing mechanical devices is more complex due to the way the structural properties of mechanical parts change as they are reduced in scale. [25] It has been said that the so-called Third Industrial Revolution (1969 – c. 2015) is based on economically viable technologies that can shrink three-dimensional objects.
Swaging (/ ˈ s w eɪ dʒ ɪ ŋ /) is a forging process in which the dimensions of an item are altered using dies into which the item is forced. [1] Swaging is usually a cold working process, but also may be hot worked. [2] The term swage may apply to the process (verb) or to a die or tool (noun) used in that process.
A Schlenk line with four ports. The cold trap is on the right. Close-up view, showing the double-oblique stopcock, which allows vacuum (rear line) or inert gas (front line) to be selected. The Schlenk line (also vacuum gas manifold) is a commonly used chemistry apparatus developed by Wilhelm Schlenk. [1] It consists of a dual manifold with ...
Deere combine used inventory was up this quarter, in line with normal season build, but down over 10% from the recent peak in spring 2024, and is currently sitting at around 60% of the prior cycle ...
The following video demonstrates the installation process of using Cold Shrink to abandon power cables. Cold shrink tubing is used to insulate wires, connections, joints and terminals in electrical work. It can also be used to repair wires, bundle wires together, and to protect wires or small parts from minor abrasion. It needs storage in ...
