Application Example Encapsulating

Dispensing of potting compound for electronics

Electronic potting compound is applied to a previously determined component or surface: This is how the encapsulating process can be described. The adhesive dosage serves a specific purpose. It protects the component during transport and against external influences. These include vibrations, impacts, moisture, dust and extreme temperatures. However, the electronic potting compound not only protects, but also improves electrical insulation and safety against damage and chemical resistance.


GJD Trusts preeflow® Micro Dispensers

The continuous improvement to work processes is part of GJD’s business. However, the bonding of a plastic lens to an aluminium housing presented the manufacturer of safety equipment with a few problems. The solution was obvious: Micro dispensers from preeflow.

Encapsulating or application of an electronic potting compound with preeflow dispenser at GJD

The high-precision dispensers improved automated production in no time at all. GJD now benefits from increased production output, reduced material consumption and a clean dosing result due to this upgrade.
