Form-in-Place
Automated technology that dispenses Form-in-Place conductive elastomer gaskets on metal or plastic housings. The system applies programmed gasket beads with pinpoint accuracy in four axes. This allows for compensation for uneven surfaces in castings and molded parts and provides consistent highly reliable seals.Gaskets can be applied on flanges as narrow as 0.50 mm,affording more space for board components or allowing smaller overall packaging.
