In modern industry, 'precise control' is no longer an optional feature but one of the core factors determining product quality, production efficiency, and energy consumption costs. Air atomizing nozzles, as key components in spraying and liquid atomization systems, are widely used in various fields with high demands on spray quality due to their high atomization efficiency, ultra-fine particle control capability, and adjustability. Compared to traditional hydraulic nozzles, air atomizing nozzles use compressed air to assist in breaking up the liquid, achieving finer and more uniform spray effects, especially under low-pressure and low-flow conditions.
Air atomizing nozzles are a type of nozzle system that uses compressed air to atomize liquid into extremely fine particles by synchronizing the air and liquid. Unlike traditional hydraulic nozzles, which rely solely on liquid pressure for atomization, air atomizing nozzles depend on the shearing force of air or internal mixing kinetic energy for secondary atomization, achieving highly uniform spray effects at very low flow rates and low pressures.
Their core structure typically includes:
- Liquid channel: Supplies the liquid to be sprayed
- Air channel: Provides compressed air for the atomization process
- Atomization chamber: The area where liquid and air mix, which can be either internal or external mixing
- Nozzle head: Controls the spray angle, particle size, and pattern (such as conical, fan-shaped, or linear)
Typical features of air atomizing nozzles include:
- Fine particle size (generally 5–50 μm)
- Adjustable flow rate and spray angle
- High atomization efficiency and uniform coverage
- Compatibility with automated control systems
Therefore, in industrial environments where high standards for atomization quality, spraying precision, and liquid utilization are required, air atomizing nozzles are the preferred solution.
In automotive whole vehicle spraying, anti-corrosion coating for construction machinery, and surface treatment of various metal components, there are extremely high requirements for paint film thickness control, edge transition, and atomization uniformity. The aerosol nozzle, with its excellent atomization control capabilities, has become an important tool for improving spray quality and saving raw materials.
Advantages and features:
• Spray particle size can be precisely controlled between 10-40 microns, providing finer coverage
• Supports multi-nozzle coordination, enabling comprehensive coating treatment of complex-shaped parts
• Automatically identifies spray angle and distance, reducing material waste by more than 30%
• Can be integrated with automatic painting robots or track systems to achieve intelligent spray lines
Common applications: primer spraying, electrocoating, automatic wheel hub painting, encapsulation gel coating, etc.
Paper products are highly susceptible to curling, cracking, or static interference during high-speed processing due to uncontrolled environmental humidity. The aerosol nozzle uses a finely adjustable micro-mist humidification system to effectively stabilize the paper tension, ensuring print quality and smooth operation of subsequent processes.
Advantages:
• Edge humidification control reduces paper deformation, enhancing stability for subsequent folding and cutting
• Provides ultra-fine mist particles (<20μm) that evaporate quickly without leaving water residue
• Works in conjunction with humidity sensors to achieve closed-loop automatic humidity regulation
• Can work in coordination with calendering, coating, varnishing, and other stages to optimize the process environment
Common applications: high-speed printing machine humidity control systems, paper laminating workshops, carton creasing processes, pre-treatment before label adhesion, etc.
In metal processing techniques involving high thermal shock and rapid cutting, traditional cooling methods often prove inefficient. Gas mist nozzles can achieve localized directional cooling and lubrication atomization, enhancing heat conduction efficiency while effectively extending tool life and optimizing surface quality of the workpiece.
Advantages and features:
• Supports micro-mist spraying of coolant, emulsion, and lubricating oil
• Adjusts spray angle based on tool shape for precise positioning
• Ensures uninterrupted cooling, prevents liquid accumulation, and avoids liquid flinging even under high-speed conditions
• Provides an integrated solution combining localized misting with overall heat dissipation
Common applications: aerospace aluminum machining, alloy steel turning, fully automated multi-axis milling centers, continuous quenching lines, etc.
Modern food production emphasizes uniformity, safety, and flavor control in spraying. Aerosol nozzles can achieve high-precision spraying of low-viscosity liquids such as oil, syrup, and flavorings, ensuring sensory quality while improving raw material utilization and production line automation levels.
Core advantages:
• Suitable for both high and low viscosity liquids such as syrups, pectin, edible oils, alcohol, and flavorings
• Made from sanitary materials like stainless steel 316L, PEEK, and PTFE, supporting CIP cleaning
• Precise spraying that does not damage food shape, suitable for delicate products
• Controls spray weight error within ±3%, effectively ensuring production line quality control
Common applications: cake oil coating, beverage bottle sterilization, sugar coating spraying, brine spraying, and interior wall spraying of flavor liquid in packaging bags.
In environmental control applications such as dust suppression, odor neutralization, and air cooling, mist nozzles atomize suppressant agents or deodorizing liquids into ultra-fine particles, rapidly dispersing them in the air to significantly enhance coverage efficiency and reduce chemical usage, especially suitable for large spaces or semi-open work environments.
Advantages:
• Fine droplets that do not form ground puddles or equipment scaling
• Support for spraying deodorants, enzymes, neutralizers, and other fluids
• Corrosion-resistant design suitable for long-term use outdoors or in high-concentration gas environments
• Equipped with mobile wind delivery platforms for regional intelligent spray control
Common applications: municipal landfills, concrete construction sites, port and dock storage areas, underground garages, industrial workshops, etc.
The electronics manufacturing industry demands high precision, cleanliness, and response speed for micro-spray applications. Aerosol nozzles achieve non-contact precise liquid application through low flow rates and high atomization ratios, making them suitable for devices and scenarios that are highly sensitive to residues and charge accumulation.
Advantages:
• Micro-spraying (flow rate as low as 0.05 L/min) with no dripping
• Uniform atomization coverage of complex component structures
• Compatibility with special chemical fluids such as pure water, isopropyl alcohol, fluorinated liquids, and fluxes
• Fast system response, ideal for high-frequency, rhythm-based work systems
Common applications: PCB cleaning, capacitor encapsulation protective layer, chip edge sealing adhesive, SMT static electricity suppression spraying, etc.
Air atomizing nozzles, as highly adaptable and adjustable spraying devices, have become indispensable technological nodes in various key industries. From energy saving and cost reduction to process optimization, from labor substitution to intelligent control, their value has long surpassed mere 'atomization'.
