Hotmelt machine VRC 601 edrive

Low pressure potting system

Flexible application

The VRC 601 edrive hotmelt potting machine is suitable for overmolding and sealing electrical components, protecting them from environmental influences such as moisture and dirt. The machine is equipped with a direct-potting single-screw extruder and three heating zones, opening up new possibilities for processing different hotmelt materials.

Modular design

The compact and modular design of the hot melt adhesive potting machine enables integration into a production line. The heat-up time is less than 20 minutes and therefore the VRC 601 has an approx. 20% lower energy consumption compared to conventional machines.

Further advantages

The electromotive closing device of the hot melt potting mold additionally increases energy efficiency. Optical process monitoring is an optional enhancement for quality assurance during production.

Modern user interface

The control system with touchscreen has an intuitive user interface for simple and safe operation of the potting system in different languages. The selection of different user roles and operating modes as well as machine networking functions enable flexible and modern process sequences.

High safety for the operator

The safety of the operator during processing of the hotmelt machine is ensured by a monitored safety device. Removal of protective covers interrupts the electrical safety circuit and the machine is stopped.

Conform with the machinery directive

The hotmelt machine fully complies with the European directives regarding mechanical and electrical safety as well as electromagnetic compatibility.
