When it is a question of EMC and the protection of your electronics from external interference as well as increased internal emission noise, we are your competent partner.
Thanks to the investment in our own vapour-plating facility, we can offer you "Everything from one supplier". To shield plastic parts, which offer no natural protection against electromagnetic radiation, we coat the inside of the enclosure with aluminium. Our extensive in-house facility guarantees short production and delivery times.
The aluminium coating is applied in a high vacuum. The 99.99 % pure aluminium is vaporised within a short period of time and is deposited on the plastic surface. The thickness of the coating is approx. 2.5 µm. The aluminium coating is also characterised by good adhesion. To achieve an even better shielding effect, other coating thicknesses are available on request.
We have certification in accordance with UL 746C for the following materials in the standard OKW colours:
The non-conducting material used for plastic enclosures, for example ABS, PC and PA, has advantages in voltage and contact protection compared with metal materials. It behaves like an insulator.
For devices that causes electromagnetic interference or whose operation is impaired by such interference, plastic enclosures without special measures offer only moderate protection.
Please keep in mind that the use of external accessories may influence the protection class, for example, and can cause corrosion. For this reason, we recommend consulting the supplier prior to using these external accessories.
Coating of other plastic materials on request.
In addition to the aluminium coating of enclosures, we can supply conductive seals in individual sizes from ø 1.5 mm - 3 mm. We will be pleased to advise you.More information
