Filling
In practice, it often starts with variation. Different products behave differently during filling: thin liquids, viscous masses, or products with sensitive compositions. At the same time, the line needs to keep running, even with changes in format or formulation, without requiring constant operator intervention.
Filling itself is the controlled dosing of product into the empty aerosol can. Depending on the product and the required accuracy, techniques such as mass flow, net weight, or piston filling are selected. This choice is determined not only by the type of product, but also by factors such as viscosity, cleanability, safety, and the required line speed. The goal is a stable process in which every can is filled consistently, without unnecessary adjustments during production.
product formulation
How the system is configured is closely related to how the product behaves. The composition of the product plays an important role in this, even though the mixing itself takes place outside the filling line. The formulation determines, for example, how well the product is dispensed from the can and how it behaves in combination with the propellant.
In some applications, the gas is part of the product’s functionality, while in others the product requires specific adjustments to function properly. This directly affects how the filling process is set up and optimized.
The right setup
The configuration of the filling system is therefore usually determined together. Depending on the application, this can range from a standalone unit for lab or pilot production to a fully integrated solution within a production line, for example combined with crimping or gassing.
In sectors such as whipped cream lines, specialized partners and proven equipment are often used. The technique that is ultimately applied depends on what needs to be produced and under which conditions. This is assessed and aligned per situation, ensuring that the process is not only technically sound, but also runs reliably in practice.
