VDS Vacuum Dispensing Systems

Quality and performance for the most demanding requirements

Increasing quality requirements and workpiece complexity or added degrees of freedom in design and engineering are just some of the many reasons to choose vacuum potting. Scheugenpflug vacuum dispensers were designed for cost-effective batch production at the highest levels of quality. All VDS systems feature a dispensing unit for 1C or 2C potting media, depending on your needs. To ensure bubble-free feeding of the potting medium, one of the A310 preparation and feeding systems is used. Powerful vacuum pumps evacuate the entire space around the component or components. This guarantees bubble-free and homogeneous filling of the components in order to achieve the required potting quality even for the most difficult dispensing tasks. To meet this requirement, various cost-effective models are therefore available both as standalone systems or for integration in a production line.


VDS B
Optimized for large workpieces

The VDS B(asic) model is specifically suited for the bubble-free potting of large to extra large workpieces. The VDS B does not include axes, since in this case it is not necessary or not possible to move the workpieces. This in turn makes the vacuum chamber more easily scalable.

VDS U
The versatile system for a wide range of applications

In electronics manufacturing, flexibility is the domain of universal systems, which allow a quick reaction to product changes. The Universal vacuum dispensing system, which usually features three motion axes and an automatic cup position, is the ideal solution for volume production of medium-sized and large workpieces. Whether working with difficult workpiece geometries, complex potting programs or a wide range of parts, with this system you are prepared for any challenge.

Advantages
  • Short cycle times by potting multiple components per evacuation
  • High component quality despite complex geometries and programming
  • Indispensable for safety-relevant and highly functional components

VDS P
Power to make time less of a limitation

Time can be a limiting factor for many reasons. This problem can be easily overcome with the VDS P(ower) vacuum dispensing system, which is usually equipped with three motion axes, an automatic cup position and a multi-piston dispenser (2 to 8 nozzles, depending on required performance; other sizes available upon request). In a single evacuation cycle, as many components as possible are processed at the same time on an even grid so that one dispensing stroke processes several workpieces at once. This system is the perfect solution for fast, premium quality potting of medium-sized or small components at very high production volumes.

Advantages
  • Short cycle times by simultaneously potting multiple components per evacuation and stroke
  • Short evacuation times due to powerful vacuum pump 
  • Indispensable for safety-relevant and highly functional components
