The global demand for high-quality aerosol packaging is surging across multiple sectors, from personal care and cosmetics to automotive and industrial chemical applications. Finding the right aerosol filling solution is paramount for scaling businesses. For startups, laboratories, and small-to-medium enterprises, committing to a fully automated line can be cost-prohibitive. To bridge this gap, our industry-leading 3-in-1 Semi-Automatic Aerosol Filling Machine provides the ultimate solution, offering unparalleled efficiency, precision, and return on investment.
1. The 3-in-1 Design Revolution: Maximizing Efficiency
Historically, semi-automatic aerosol production required operators to manually transfer cans between three distinct standalone units: a liquid filler, a valve crimper, and a gas filler. Our 3-in-1 model represents a massive upgrade, optimization, and integration of these processes.
By centralizing the operations, the liquid filling head, sealing head, and gas filling head are now systematically distributed and mounted in a straight line upon a single, robust bracket on one unified workbench. This completely revolutionizes the classic workstation positioning.
During production, the operator simply pushes the aerosol cans smoothly from the left side along the guide board until they hit the right-side limit baffle. With a single press of the foot pedal, the machine executes the liquid filling, sealing, and gas filling actions simultaneously. Once finished, the operator removes the completed cans from the front, meaning only one single person is needed to operate the entire aerosol filling machine setup.
2. Core Technical Specifications & Capabilities
Built for versatility, the AL-SHY-A model is perfectly suited for laboratory environments and small-scale production processing. It is highly adaptable to a vast array of formulations. Here are the core parameters that drive its performance:
- Production Capacity: Achieve outputs of 650 to 800 cans per hour (using a 450ml filling volume as a reference).
- Filling Capacities: Capable of delivering a maximum liquid filling volume of 450ml and a maximum propellant gas filling volume of 450ml.
- Extreme Precision: Both the liquid and propellant repeat filling accuracy are strictly maintained at ≤±1.0% (or ≤±1.0g), ensuring product consistency.
- Applicable Cans & Valves: Designed for standard 1" valves. It handles aerosol cans with a diameter of 35mm to 70mm and a height range of 80mm to 315mm.
- Sealing Specs: Delivers a precise sealing diameter of (27.1-27.3) ±0.15mm and a sealing depth of (4.9-5.1) ±0.15mm.
3. Step-by-Step Operational Workflow
We designed this machine to be incredibly user-friendly. Before starting the primary production run, the workflow is highly logical. First, the operator connects the compressed air source and opens the liquid material pipeline and propellant (such as LPG, DME, or R134a) pipeline valves.
The control panel features intuitive switch knobs. Turning them clockwise activates the respective actions, while the green reset button forces an emergency reset during debugging or abnormal conditions. Before formal production, operators must exhaust all air from the liquid material cylinder and pipelines, conduct a trial fill, and weigh the can to confirm the measurement is 100% accurate. Furthermore, by toggling the knobs on the operation panel, the operator can isolate the machine to perform any single action individually if needed.
4. Precision Setup & Adjustments
To ensure flawless production across different can dimensions, the machine offers granular mechanical adjustments:
Head Height Adjustment
By loosening the adjustable handle and turning the lifting handwheel, the entire carriage moves vertically. The optimal height is achieved when the lowest end of the liquid filling head is precisely 2-3mm away from the mouth of the aerosol can. Operators must align the centers of the filling and gas heads with the respective cans before locking the screws.
Liquid Volume Adjustment
Adjusting the liquid dosage is straightforward. By rotating the designated handwheel on the liquid filling machine, operators can match the requirement against the visible measuring scale attached directly to the cylinder.
Sealing (Crimping) Depth and Diameter
A perfect seal is critical for aerosol safety. The sealing head features knurled adjustment rings. Rotating the upper ring to the right increases the sealing diameter, while rotating it left decreases it. Similarly, rotating the lower ring to the right increases the sealing depth, and turning it to the left reduces the depth.
5. Uncompromising Pneumatic Safety
Because aerosol filling often involves highly flammable propellants, safety cannot be an afterthought. The AL-SHY-A is a fully pneumatic system. The liquid filling mechanism is driven by standard pneumatic cylinders for higher stability, smoother action, and reliable performance. Similarly, the gas filling head utilizes a standard short cylinder as its execution element, resulting in an exquisite structure and beautiful appearance.
The system requires a working air pressure between 0.50 and 0.70 MPa (or 0.60-0.80 MPa depending on precise configurations). We utilize premium components, including SMC pressure regulators, SMC mechanical valves, AirTAC cylinders, and AirTAC hand slide valves, ensuring maximum durability.
6. Maintenance & Troubleshooting
Keeping your aerosol filling solution running smoothly requires minimal but consistent maintenance. Always check that the oil mist lubricator on the air source treatment unit has sufficient oil, and ensure your compressed air is dried, as moisture can cause severe instability. Frequently check moving parts and add lubricating grease, and immediately tighten any loose screws or nuts. When your shift ends, cut off the air supply and close the liquid and propellant valves.
If issues arise, our intuitive design makes troubleshooting simple:
- Inaccurate Liquid Measurement: Often caused by air bubbles in the pipeline, an unreliable one-way valve seal, or a failing piston seal. Simply exhaust the bubbles or replace the affected sealing components.
- Poor Sealing: This could be due to an incorrect sealing diameter/depth setting, incorrect head height, or substandard cans/valves. Readjust the dimensions or ensure you are using qualified packaging materials.
- Slow Booster Pump Output: This typically means the propellant is empty, there is too much gas phase (instead of liquid phase) in the pipeline, or the piston seal has failed. Replace the gas cylinder or bleed the pipeline to allow liquid phase entry.
