Custom Aerosol Actuator Circular Nozzle

When designing a circular nozzle for an aerosol, what factors (such as aperture size and spray angle) affect its spray effect and applicable product types?

When designing a aerosol actuator circular nozzle, there are several key factors that significantly affect the spray effect and applicable product types, especially those closely related to spray uniformity, spray range and spray type. Shanghai Quntong Spray Packaging Material Co., Ltd. ensures that these factors are precisely controlled to meet the needs of different aerosol products through its sophisticated design and advanced automated production processes.

1. Aperture size
The aperture size directly affects the spray particle size and flow rate of the aerosol. Smaller apertures produce finer spray atomization effects and are suitable for products that require high uniformity, such as personal care products (e.g., perfumes, cosmetics) and detergents. Shanghai Quntong uses its advanced production equipment (such as 10 one-inch automatic valve production lines) to accurately control the aperture size to ensure the stability and consistency of the spray effect.

2. Spray angle
The spray angle determines the coverage and direction of the spray. Circular nozzles usually have a fixed spray angle, and the product's use environment needs to be considered when designing. For products that require wide-area spraying (such as indoor air fresheners or disinfectants), a larger spray angle is more suitable. In some precise positioning applications (such as certain pharmaceutical sprays), a smaller spray angle and high-precision nozzle design are more effective. Shanghai Quntong uses automated production lines to ensure that the spray angle of each nozzle meets precise requirements during the design process to meet the different needs of customers.

3. Airflow pressure
Airflow pressure affects the diffusion effect of the spray and the continuity of the spray. Higher airflow pressure can ensure the uniform distribution of the spray and is suitable for most common aerosol products. Low-pressure systems are suitable for products that require delicate and gentle sprays, such as some delicate personal care products or air fresheners. Shanghai Quntong's production lines, including a variety of automatic and semi-automatic valve production lines, can adjust the appropriate airflow pressure according to the needs of different products.

4. Material selection
The durability and corrosion resistance of the nozzle material directly affect the service life of the sprayer and its ability to adapt to different liquids. For example, some detergents or chemicals may corrode plastics and metals, so chemical-resistant materials need to be selected. Shanghai Quntong uses high-quality plastic and metal materials and passes strict quality control to ensure that the nozzles have sufficient durability and long-term stability.

5. Spray type and viscosity
Different sprays (such as liquids, foams or dry powders) have different rheological properties (such as viscosity and surface tension), which will affect the design of the nozzle. For example, liquids with higher viscosity (such as paste or cream products) usually require nozzles with larger apertures for effective spraying. For aerosol products, the nozzles need to be designed more precisely to ensure the best atomization effect. Shanghai Quntong's nozzle design takes these factors into consideration, so that the spray effect of each product can match its characteristics.
