Products Description
Bag-On-Valve (BOV) filling machine is a type of aerosol filling machine designed to fill products into aerosol containers that use Bag-On-Valve technology. In this system, a flexible bag is placed inside the aerosol can, and the product to be dispensed (e.g., liquids, gels, creams) is filled into the bag. The valve at the top of the can is used to release the product when pressure is applied.
Advantages of BOV Filling Technology
1.Separation of propellant and product:
Since the product is inside the bag and the propellant is outside, this keeps the two separate, ensuring that the product remains pure and uncontaminated.
2.Continuous and controlled spraying: The BOV system allows for consistent spraying, as the propellant pushes out the product from the bag evenly.
3.Improved environmental friendliness: BOV systems use compressed air or nitrogen instead of harmful propellants like CFCs (chlorofluorocarbons).
4.360-degree usability: Aerosol cans using BOV technology can be used in any position, making them more versatile.
5.Less waste: Nearly all the product can be dispensed, reducing waste inside the can.
How does the BOV filling machine works?
A Bag-On-Valve (BOV) filling machine operates through a series of precise steps to fill aerosol cans while maintaining the integrity of the product and propellant. Here's an overview of how it works:
1.Can preparation:
Empty aerosol cans are cleaned and prepared for filling.
2.Valve placement:
The bang-on-valve is placed into the can.
3.Crimping valve
The crimping machine uses a crimping head that descends onto the valve, compressing the metal edge (called the ferrule) around the valve stem to form a tight seal.The crimp creates a sealed connection between the valve and the can, ensuring no product or gas can escape.
4.Propellant filling
The propellant such as compressed air, nitrogen, CO₂.These gases are environmentally friendly and do not interact with the product inside the bag.Then the propellant is injected through the valve into the space between the outer surface of the bag and the inner walls of the can.The propellant fills the area outside the bag, not inside it, which creates pressure that collapses the bag as the product is dispensed.
5.Filling the product into the bag
The product is filled through the valve after the bag has been crimped onto the aerosol can. It controls the precise amount of product being filled into the bag. Since the product inside the bag never comes into contact with the propellant, it remains pure and uncontaminated. This is especially important for sensitive products such as pharmaceuticals,cosmetics and food.
6.Pressure gauge test
Correct internal pressure ensures the aerosol can dispenses the product effectively and consistently.Ensuring the right pressure is key to preventing leaks, valve malfunction, or can explosions during transportation or storage.A pressure gauge can be manually used to measure the internal pressure of the aerosol can.
7.Actuator and cap placement
The spray nozzle or actuator is installed onto the valve. The capping process ensures the aerosol can is properly sealed and ready for use by consumers. This ensures the cap is securely fixed and won't come loose during handling or use.
Packing and shipping
By following a detailed process for packing and shipping aerosol filling equipment, Yangzhou Meida ensures that our products arrive safely and efficiently at customers destination, ready for installation and use.
1. Preparation for Packing
Quality Inspection: Each piece of equipment undergoes thorough quality checks to ensure it meets manufacturing standards and is free of defects before packing.
2. Disassembly (if needed)
Component Separation: Larger machines may be partially disassembled to facilitate packing and reduce shipping costs. Components are carefully labeled for easy reassembly.
3. Packing Materials
Protective Packaging: The equipment is wrapped in protective materials like bubble wrap, foam, or custom-fit packaging to prevent damage during transit.
Wooden Crates or Pallets: Equipment is often packed in sturdy wooden crates or on pallets, providing additional protection and making handling easier.
4. Labeling
Clear Labeling: Each package is clearly labeled with handling instructions, destination details, and any necessary regulatory information to ensure proper handling during transportation.
5. Logistics and Transportation
Shipping Arrangements: Yangzhou Meida coordinates logistics for transportation, selecting appropriate carriers based on the destination and urgency.
Tracking: Shipping details are provided, allowing for real-time tracking of the equipment during transit.
6. Documentation
Shipping Documents: All necessary documentation, including invoices, export licenses, and customs paperwork, is prepared to comply with international shipping regulations.
