Aerosol Can Filling Machine

A complete scope review normally considers product filling, valve placement, crimping, propellant or compressed-gas filling, leak testing, weight checking, coding and discharge handling. The exact sequence depends on whether the project uses conventional aerosol or bag-on-valve technology. The supplier should identify every included station, manual operation and excluded utility or safety item. A liquid filler alone is not a complete aerosol production line. The written quotation and layout should show the proposed process sequence and responsibility boundary.

Provide the product formulation or safe handling description, liquid dose, propellant type and dose, can dimensions and material, valve and actuator specifications, crimp dimensions, target output and required leak-test method. Also provide the site's electrical supply, compressed-air conditions, ventilation concept, hazardous-area classification and local compliance requirements. Send representative cans, valves and product samples for trials where permitted. The supplier should confirm the technology route, station sequence, tooling, test method, safety boundary and documentation scope before issuing the final technical offer.

Decide the packaging route before selecting the filling line. Conventional aerosol places the product and propellant in the can system, while bag-on-valve keeps the product inside a bag attached to the valve and uses compressed gas outside the bag. The two routes require different components, filling sequences and tooling. Buyers should confirm the product's compatibility, barrier requirement, dispensing behavior, target pressure, can and valve supply, and local regulatory expectations with their packaging and formulation specialists. A quotation should not substitute one route for the other without written review.

Ask for a station-by-station process description, general arrangement drawing, utility list, component schedule, sample-test plan and acceptance criteria. A reference video is useful only when it shows a process route comparable to the proposed line; it should not replace testing with the buyer's can, valve and product. The factory acceptance test should cover dosing, valve placement, crimp quality, propellant filling, leak detection, weight checks, alarms and safe shutdown within the agreed scope. Record any functions that will be completed only during site commissioning.

The main factors are automation level, production speed, conventional or bag-on-valve technology, product and propellant dosing method, valve placement, crimping control, leak testing, checkweighing, coding, conveyors, safety design and documentation requirements. Can and valve change parts, product-contact materials, sample testing and site commissioning also affect the quotation. Buyers should compare offers by included stations, acceptance criteria and responsibility boundaries rather than only by headline machine price. Final delivery time should be confirmed after samples, technical scope and approval drawings are complete.
