Piezo-based jet valve with nozzle heating

The DELO-DOT D4 dispensing valve is a piezo-based system for contactless dispensing of liquid media. Its dispensing frequency for permanent dosing is up to 1,500 drops per second makes dispensing processes significantly faster.

DELO-DOT D4 allows liquids, lubricants, and adhesives (viscosity > 5,000 mPa·s) to be jetted onto the substrate in reproducible volumes with maximum precision. Thanks to the integrated nozzle heater, the viscosity of the media to be dispensed can be optimally adjusted to the process. In miniaturization, very tiny volumes of up to 2 nl can be accurately dispensed.

The dispensing valve features a modular design, incorporating the entire fluid system – consisting of media channel, plunger, nozzle, and nozzle seat – as one single unit. The system can be disassembled and cleaned in a few simple steps, which allows downtimes to be kept to a minimum.

With its compact dimensions of 86 mm x 17 mm x 52 mm, the dispensing unit is ideal for space-saving integration into a variety of systems.

  • Modular design
    makes disassembly and cleaning easy
  • Optimal integration
    thanks to its compact and space-saving design
  • Piezo-based system
    reduces operating costs, since no compressed air is needed

LED curing lamps for quick adhesive curing processes

Speed is often the focus when it comes to using adhesives. UV curing lamps enable fast curing and are therefore often indispensable in the production process.

UV LED lamps offer technical properties that deliver significant advantages for adhesive curing:

  • Light intensity adjustable to a constant high level
  • Useful life can exceed 20,000 hours  (“on” time = lifetime)
  • Low operating costs through low current consumption and low costs for maintenance and spare parts
  • No warm-up time and therefore ready for operation immediately
  • Reproducible curing properties on the entire irradiated area
  • Very low heat development at the component
  • Compact design

DELO dispensing equipment for precise adhesive dispensing

Adhesive, application and desired degree of automation – these factors are decisive for the selection of suitable dispensing equipment, such as dispensing guns, valves and pressure tanks.

DELO’s adhesive dispensing equipment is precisely adapted to its high-tech adhesives and enables optimum production processes. You benefit from cost-effective adhesive processing that can be integrated into the process flexibly. Jet systems, in particular, must operate precisely and fast, and must be compact. Precision is necessary for the accurate and reproducible application of tiny adhesive quantities; speed enables fast processes, while a compact design allows integration into any production system.
