The electrical properties of partially metallized plastics parts and their influencing factors produced with the in-mould-metal-spraying (IMMS)

The In-Mould-Metal-Spraying (IMMS) combines the thermal spraying of metals and the injection molding of plastics to provide a more efficient way of producing partially or fully metallized plastics parts for electrical applications. To qualify the IMMS process for the production of electronic parts, detailed investigations of the influence of the specific coating structure on the possible active and passive electrical properties are necessary. The following article gives an overview about the electrical conductivity and ampacity of IMMS parts on one hand and the possible electromagnetic shielding effectiveness on the other hand.
