Main properties of plastic raw materials used for enclosures

Main properties of plastic raw materials used for enclosures

The classic housings, with only 5 sides and a lid, require a long and costly layout, most of the time ignoring the application needs: security, fire resistance, water penetration, shocks, UV, temperature, etc.

Main properties of raw materials used for enclosure gaskets

The material was not chosen in regards of its price or ease of molding like gaskets made of PU foam injected through the process “Formed in place foam gasket or FIPFG “, or even of the possibility of die-cutting, but to meet the technical requirements of ...

Main characteristics of the heat shrinkable sleeves

Heat shrinkable sleeves were invented in 1960 by the company Raychem. The tubes are made by extrusion, and subjected to molecular modification by radiation of an electron gun.

Comparison of the characteristics of the main magnets types

Selecting a magnet for a level switch application must take into account the characteristics of the liquid in which it will be immersed, of the temperature at which it will be subjected, of its corrosion resistance, of the magnetic field required to operate...
