Material forwarding systems are the foundational part of any automated dispensing setup. Their purpose is to prepare, store, and reliably transport materials from bulk containers to the dispensing valve or head. This is especially critical for materials that are highly viscous, prone to settling, or sensitive to air.
Key components and functions of a material forwarding system include:
- Pumps: Piston, gear, or progressive cavity pumps are used to move high-viscosity fluids and pastes from large drums or pails.
- Pressure Vessels: Pressurized tanks use air to push low-to-medium viscosity fluids to the dispensing point, ensuring a consistent and uninterrupted flow.
- Degassing and Homogenization Units: For materials that contain dissolved air or filled particles, these systems degas and mix the material under vacuum to prevent air bubbles, which can cause dispensing inconsistencies.
- Fluid Hoses and Connectors: Specialized hoses and fittings are used to create a leak-proof connection from the source to the dispensing valve, often designed to handle high pressures and various chemical properties.
