1,Suitable for operation, often opening and closing fast, lightweight
2,Fluid resistance is small
3,Simple structure, relatively small volume, light weight, easy to maintenance
4,Sealed performance is good
5,Not limited by the installation direction, the flow of medium can be arbitrary
Deep drawing forming process
Deep drawing is a kind of stamping technology of hollow part which is made by using special tool to cut or cut open hollow parts.
The characteristic is that the plate is driven by the convex die, which can flow into the die, that is to rely on the material flow and elongation rate.
Bulging forming process
Expansion is the use of mold forced blank thickness reduction and surface area increases, in order to obtain the geometry of the parts stamping process.
The characteristics of blank holder was crushed to death, not to flow into the die, completely rely on the extension of material forming.
Flanging is used to mold blank on the hole edge or outside
A processing method for stamping edge vertical edges, in the middle stage of flanging, namely punch below material has not been completely transferred to the side before, if you stop the deformation, forming will be shown on the right, this process method called reaming, production and application are also common.
Spandex, Lycra or elastane is a synthetic fiber known for its exceptional elasticity. It is a polyether-polyurea copolymer that was invented in 1958 by chemist Joseph Shivers at DuPont's Benger Laboratory in Waynesboro, Virginia.
The name "spandex" is an anagram of the word "expands". It is the preferred name in North America; in continental Europe it is referred to by variants of "elastane", i.e. Ã©lasthanne (France), Elastan (Germany, Sweden), elastano (Spain), elastam (Italy) and elastaan (Netherlands), and is known in the UK, Ireland, Portugal, Spain, Brazil, Argentina, Australia, New Zealand and Israel primarily as Lycra. Brand names for spandex include Lycra (made by Koch subsidiary Invista, previously part of DuPont), Elaspan (also Invista), Acepora (Taekwang), Creora (Hyosung), INVIYA (Indorama Corporation), ROICA and Dorlastan (Asahi Kasei), Linel (Fillattice), and ESPA (Toyobo).
