MUSASHI dispensing systems overview

MUSASHI Engineering, Inc. from Japan, one of the leading manufacturers for dosing technology, offers a broad product portfolio. From manual dosing devices to complex dosing systems in automated plants and as one of the few manufacturers also the plants themselves. These range from table-top dosing robots and gantry systems for integration to complete inline systems and production lines. In addition, MUSASHI also manufactures the consumables that
Dispensing needles and cartridges, as well as hoses and sealing plugs. This ensures high precision and quality throughout the entire dosing technology process chain, from from the dispensing needle to the complete dispensing system.

The following dosing unit types are available:

• Pressure-time dispenser (AirPulse Dispenser)
• Jet-Dispenser
• Mechanical dosing units (volume dosing units)
• Dispensing valves

In addition, the following machine platforms are available for automation:

• Table robot ShotMaster
• Portal robot CrossMaster
• Inline machines FA-Machines

One of the most universal and widespread dosing principles is the pressure-time system. Here, the material to be dispensed is supplied in cartridges. Dispensing takes place via a pressure pulse on the material surface inside the cartridge. The air presses on the material and pushes it through the dosing needle onto the dosing point. For this purpose, an electro-pneumatic valve "switches through" the compressed air applied from outside for a short period of time.

One dosing method that is becoming increasingly important due to its advantages is jetting. The material to be dispensed is pressed into the dispensing into the dosing chamber. There, a moving piston accelerates the medium and flings it through the nozzle onto the substrate, similar to an inkjet printer. inkjet printer. Depending on the material to be dispensed, the working distance can be several millimetres.

Since there are no dispensing needles, the process is robust against height tolerances. The dispensed quantity is defined solely by the dosing chamber, the mechanically adjustable piston stroke and the number of dots to be dispensed and is therefore precise and reproducible.

Mechanical dispensers are suitable for media with fillers or high viscosity. Depending on the application and material properties, screw feeders are suitable, piston feeders, screw feeders.

There are a variety of 2K dispensing media. For high-precision applications, the two components are premixed externally (pre-mix) and then processed within the pot life. processed. No-mix adhesives and media and systems with activator can be dispensed with jet dispensers. Applications with higher material application are dosed with dispensed with two mechanical dispensers and mixed in a static mixer directly during dispensing.

Dispensing robots, table robots or TableTops, have several areas of application: from process validation in the laboratory to small-batch production and series production. with individual stations in the lean concept (Chaku-Chaku).

The gantry robots from MUSASHI can be mounted on automatic units and are therefore also ideally suited for use in inline systems. ATN supports you in the selection and integration.

Musashi also offers inline dispensing systems for the production of large series. Due to the standardised interfaces, the dispensing systems can be equipped with all dispensers and dispensing systems. dispensers and dispensing systems.

MUSASHI as a manufacturer of precision dispensing systems also offers a matching cartridge and dispensing needle system. The accessories from MUSASHI are conceptually and variable, thus enabling a consistently high precision in the dispensing results.
