Standard commercial aerosols rely on 1-inch (25.4mm) aperture valves for large can openings. In contrast, Metered Dose Inhalers (MDIs) and micro-dosing sprays utilize miniature 1/2-inch (approx. 13mm) valves on narrow aluminum or tinplate cans (Φ22–28mm) for targeted pulmonary, nasal, or oral administration.
Standard filling lines cannot crimp or gas miniature 1/2" containers without crushed necks or valve stem leakage. The AILE AL-ZP-MDI rotary platform provides custom star-wheel pocket indexing, miniature expanding crimping collets, and ultra-fine SUS316L volumetric metering designed specifically for small-batch pharmaceutical and laboratory aerosol production.

Request Quotation & Technical ConsultationAn MDI (Metered Dose Inhaler) filling machine is a specialized packaging system engineered for pharmaceuticals and micro-dose sprays under 60ml. Operating on an indexing rotary star wheel, the machine coordinates three core operations: micro-volume liquid dosing, high-precision valve crimping, and through-the-valve propellant charging in an enclosed, pure pneumatic workstation.
The standard AL-ZP-MDI is configured for 1/2-inch (approx. 13mm) miniature aerosol valves and compact aerosol cans with diameters between Φ22 mm and Φ28 mm and heights between 45 mm and 150 mm. Customized pucks and crimping heads can also be machined for project-specific container geometries.
No electrical power supply is required. The AL-ZP-MDI features a 100% pure pneumatic control architecture driven solely by compressed air (0.6–0.8 MPa). Because there are no electrical components, motors, or switches, it completely eliminates electrical spark hazards when handling flammable propellants (such as butane, propane, or LPG) or volatile medical solvents.
The machine delivers a maximum liquid dosing volume of 15 ml and a maximum gas charging volume of 25 ml, with an accuracy within ≤ ±0.5 g. It is purpose-built for high-precision micro-dosing applications such as asthma inhalers, throat sprays, and targeted medical mists.
The high-pressure gas filling head supports a wide variety of propellants, including medical-grade R134a / HFA-134a, nitrogen (N₂), Freon blends, butane, and propane. The booster pump maintains stable charging pressure regardless of gas supply fluctuations.
Yes. All liquid-contact parts (including metering cylinders, fluid pipelines, and dosing nozzles) are manufactured from sanitary SUS316L stainless steel with fine mirror polishing. The machine frame is built in durable SUS304, meeting pharmaceutical cleanroom and GMP manufacturing compliance.
Yes, physical samples are strongly recommended. Because miniature 1/2-inch valves, crimping depths, and can profiles vary across manufacturers, providing 20 to 30 empty cans and valve samples ensures AILE engineers custom-machine star-wheel pockets, crimping collets, and gas nozzles to your exact packaging dimensions prior to factory testing.
