Cellular Metals - Structures made from joined hollow metal spheres mounting

Cellular Metals - Structures made from joined hollow metal spheres mountingExpanded polystyrene beads (aka styrofoam) are coated with a slurry of metal powder and a binder. The coated beads are heat treated to evaporate both the styrofoam bead and the binder, leaving only fragile hollow metal powder shells. Further heating (sintering) causes the shells to solidify and also joins the shells where they touch. The process allows the production of lightweight cellular metals with a uniform and reproducible cell structure,

Components can be vacuum-coated and it is also possible to get coated plastic or metal foil with self-adhesive backing for easy attachment

The spun yarns are used to make EMC shielding textiles and anti-static work clothing for assembly workers in the electronics industry

The coated beads are heat-treated to evaporate both the styrofoam bead and the binder

the mould is opened and the part is ejected

The sample measures 8 cm x 8 cm x 1 cm

The samples are selected to show the wide range of possible patterns

to make integral flexible hinges

It is available in both standard and heavy-duty variants sold in rolls with a width of 114

Paper with printed NFC antennas combined with very small NFC chips is used for intelligent packaging

There are two variants - one transmits 20 percent light and the other 38 percent

Laminated shims are constructed from a large number of thin sheets
