About Precision Microdispensing Jetting Valve for Medium to High Viscosity Materials

The VERMES MDS 3280 microdispensing jetting valve system dispenses material in small volumes at fast speeds with extremely high accuracy and repeatability. The rising miniaturisation of individual components in production processes demands smaller beads and lines for dispensing whilst increasing production throughput, process reliability and consistent repeatability.

Based on piezoelectric fluid jetting technology, the VERMES MDS 3280 allows for contactless application of materials at high speed with precision at a faster dispensing rate than pneumatic valves.

The VERMES MDS 3280 is recommended for dispensing medium to high viscosity materials up to 2,000,000 mPas in repeatable single dots or beads of ≥0.5 nl. Example fluids include SMT adhesives, conductive adhesives, silicones, LED phosphor, underfillers, hot melts and solder pastes. These materials can be supplied to the valve via a choice of media such as 3ml to 55ml cartridges or pressure pot and hose interface.

For the dispensing of medium viscosity materials, please see the VERMES MDS 3050+.

The system minimises initial set up with its top adjust design “Quickadjust” allowing for easy configuration and adjustment of the tappet and nozzle. An easy cleaning process, including a fluid box that has one-click screwless removal, reduces downtime, optimising production throughput and efficiency.

Specific to production requirements, components of the valves including tappets, nozzles and heating options can be customised to optimise the dispensing process of your application.

Features & Benefits

  • Ultra-precise contactless dispensing
  • Suitable for high (up to 2,000,000 mPas) viscosity materials
  • Reduced production times and increased throughput as a result of fast speeds: frequency >3,000Hz
  • Easy-to-remove/replace fluid box for straight-forward cleaning or interchanging of fluids
  • Multiple customisable configurations using interchangeable parts
  • Integrated fluid box heater regulates process temperature for consistency
  • Easy cleaning process reduces downtime of equipment
  • “Quickadjust” design minimises set up time of tappet and nozzle and makes further adjustment easier
  • Peerless integration into tightest spaces
  • Incredible application flexibility
