marc0 Gantry System is a compact, high-precision dispensing platform for standalone and benchtop production.

The robust gantry frame enables dynamic movement with up to 2g acceleration and ±5 μm reproducibility. The worktable includes mounting points for conveyor belts or custom fixtures, making it suitable for automated loading and unloading.

An integrated station in front of the work area supports calibration and maintenance tasks. It can be equipped with a variety of combination of components, such as vacuum suction tool for purging, nozzle cleaning station, a touch sensor for position detection, and a Lookup Camera for visual inspection.

Whether as a benchtop unit or a stand-alone machine , marc0 Gantry System delivers stable, repeatable dispensing performance for advanced applications.

The marco 3-liter vacuum tank is designed for low-viscosity media in precision dispensing systems.

Its body consists of a milled steel block, allowing for easy cleaning. An integrated Venturi nozzle generates vacuum levels down to 300 mbar, supporting efficient material handling and degassing. For deeper vacuum requirements, an external vacuum pump can be connected directly to the lid.

The tank is compact and modular, making it easy to integrate into various production environments. Combined with marco systems’ in-house developed pressure booster pump, the tank ensures a constant and controlled supply of media to the dispensing system.

Its clean design and reliable vacuum generation make it ideal for semiconductor or electronics assembly applications where material purity and process control are essential.

The HotMelt System from marco is designed for high-precision dispensing of reactive polyurethane-based hot melt adhesives. I

t features a modular dispensing valve and a 30 cc heated tank, divided into three heating zones to progressively melt the material to the ideal dispensing temperature.

The dispensing valve operates at up to 4000 Hz for fast, repeatable application of lines or dots as small as 0.3 mm. The entire system is modular - each component in contact with the medium can be easily removed, cleaned or replaced. This design ensures stable processing, minimal downtime and consistent results.

Ideal for semiconductor and electronics applications where precise, clean adhesive dispensing is essential.

marco systems’ two-component mixing head combines precise mixing and dispensing in a single compact unit.

Unlike conventional systems that require separate mixing and dispensing steps, the 2C mixing head blends the components directly before application. Stepper motors control the feed rates with volumetric tolerances of less than 0.5%, ensuring precise ratios even with challenging materials.

This design prevents curing inside the machine or lines – only the disposable mixing helix contacts the mixed medium.

Dynamic mixing options with a separate motor are available for applications with extreme mixing ratios or high demands on homogeneity. Specially developed modular mixing spirals enable consistent and reproducible results. An optional automatic changeover system supports increased automation.

The compact design streamlines dosing processes and helps reduce material waste, downtime, and maintenance effort.

In precision dispensing, even small pressure fluctuations can cause dosing errors, especially with sensitive materials or long fluid lines. Common issues like pressure spikes, flow surges or unstable tank pressure often lead to inconsistent results.

The marco PushMembrane solves this by stabilizing the pressure between material supply and dispensing head. A controlled pneumatic-oil reservoir applies consistent force to the fluid via a flexible membrane. When the internal volume decreases, an inlet valve refills the membrane—without interrupting flow. This ensures the dispensing valve always operates under stable pressure, regardless of tank distance or upstream pressure behavior. The PushMembrane is installed inline between the tank and valve, making it an effective upgrade for improving accuracy and repeatability in any advanced microdispensing setup.

The SJet and SJet Power valves are marco’s high-speed piezo dispensing valves for contact and non-contact dispensing. The SJet Power valve is more powerful, has a more rigid design and was developed for highly viscous materials. Interchangeable valve seats meet fluid and process requirements.

A precision actuator enables ultra-fast, reliable dispensing with a volume tolerance of less than 1%. The modular design supports a wide range of fluids and makes the valves ideal for semiconductor processes requiring speed and accuracy. Whether jetting or needle dispensing, both ensure consistent results. They can be supplied from a cartridge or combined with a pressure tank system.
