Aerosol Packaging Equipment

Filling, Valve Crimping and Propellant Charging

Aerosol packaging requires coordinated product filling, valve placement, controlled crimping, propellant charging and pressure inspection. The machine configuration must match the product formula, aerosol can, valve, actuator, propellant and applicable factory-safety requirements.

01

Aerosol Liquid Fillers

Dispense the required amount of liquid product into compatible aerosol cans before the valve is installed and sealed.

02

Valve Crimping Machines

Position and mechanically crimp compatible aerosol valves to the can opening using tooling matched to the valve and container.

03

Propellant Filling Machines

Charge a compatible propellant through the configured filling system after the valve has been sealed to the aerosol can.

04

Integrated Aerosol Systems

Combine liquid filling, valve crimping and gas charging in a compact three-in-one machine or an automatic production line.

Typical Conventional Aerosol Filling Process

01 Can Feeding Empty compatible aerosol cans enter the filling station
02 Product Filling The programmed amount of liquid product is dispensed
03 Valve Placement A compatible aerosol valve is positioned on the can
04 Valve Crimping The valve is crimped using matched sealing tooling
05 Gas Charging The specified compatible propellant is charged
06 Testing & Assembly Pressure, leakage, actuator and cap can be inspected

Common Aerosol Packaging Applications

Body Spray & Deodorant
Facial Mist & Hydration Spray
Hair Spray & Styling Products
Household Cleaning Spray
Spray Paint
Air Freshener
Industrial Maintenance Spray
Compatible Food & Medical Sprays

Choosing an Aerosol Filling Configuration

Individual Operations

Separate Workstations

Manual or pneumatic liquid fillers, valve crimpers and gas fillers support low-output production and flexible equipment arrangement.

Compact Production

Three-in-One Machine

Combines product filling, valve crimping and gas charging in one compact system while retaining operator-assisted can handling.

Continuous Production

Automatic Aerosol Line

Connects filling, valve placement, crimping, gas charging, inspection and actuator or cap assembly through an automated conveying system.

Conventional Aerosol vs. Bag-on-Valve

Comparison Conventional Aerosol Bag-on-Valve Aerosol
Product Position The product and compatible propellant occupy the aerosol container according to the selected formulation. The product is held inside a flexible bag attached to the aerosol valve.
Pressure Medium Uses a propellant selected for the product, valve and intended spray performance. Pressure is applied outside the bag so the pressure medium remains separated from the product.
Filling Sequence Commonly includes product filling, valve crimping and propellant charging. Requires BOV-compatible bagged valves, pressure charging, crimping and product filling through the valve system.
Machine Requirement Requires equipment matched to the can, valve, product and selected propellant. Requires dedicated BOV filling and crimping equipment matched to the bagged valve and can.

Aerosol Filling Machine FAQ

What does an aerosol filling machine do?

Depending on its configuration, it can dispense the liquid product, crimp the aerosol valve and charge a compatible propellant. These functions may be performed by separate machines or one integrated system.

What does BOV mean?

BOV means Bag-on-Valve. The product is filled into a flexible bag attached to the aerosol valve, while the pressure medium remains in the space between the bag and the can.

Can a conventional aerosol machine fill BOV containers?

Not automatically. BOV containers require compatible bagged valves, dedicated filling heads, suitable crimping tooling and a different filling sequence. The machine must be designed or configured specifically for the selected BOV package.

Can one machine fill both liquid and gas?

A three-in-one aerosol machine can combine liquid-product filling, valve crimping and compatible propellant charging. Its filling heads, valves and controls must match the intended materials.

Why must the aerosol valve be crimped?

Crimping mechanically secures and seals the valve to the aerosol can. The crimp diameter, crimp depth and tooling must match the selected can and valve specifications.

Can aluminum and tinplate cans use the same machine?

A machine may handle compatible aluminum or tinplate aerosol cans, but the can dimensions, neck specification, valve, positioning parts and crimping tooling must be confirmed for every format.

What inspections are needed after filling?

The process may include fill-weight checks, crimp inspection, pressure or leakage testing, water-bath testing where appropriate, actuator inspection and final functional testing according to the product and applicable requirements.

What information is needed to configure a machine?

Provide the product formula, target liquid volume, selected propellant, can and valve specifications, actuator, required output, operating environment, local safety requirements and actual package samples where possible.
