Tinplate Aerosol Can: How Internal Structure Reduces Harsh Spray Noise for Premium Fragrances
2026-03-23
For brands deeply engaged in the premium fragrance sector, the sensory experience of products is never limited to the level of fragrance. The sound when pressing the spray has long become an invisible standard for measuring brand texture. Many brand owners have found that the sharp hissing sound emitted by ordinary tinplate aerosol cans during spraying will directly lower the high-end tone of products, and even make consumers question product quality. To create packaging that fits the positioning of premium fragrances, controlling noise by optimizing the internal structure of tinplate Aerosol Cans has long become a key link in improving product competitiveness, which is also the core technical direction SAILON focuses on when customizing premium fragrance tinplate aerosol cans.
Most people only pay attention to the top, middle and base notes of fragrances, but rarely notice the physical logic behind spray noise. In fact, this harsh sound is not just a simple airflow sound, but the result of the combined action of fluid movement and tank structure. When the propellant flows quickly through the valve orifice inside the spray silent tinplate aerosol can, the pressure difference between the inside of the can and the outside will instantly form cavitation. Micro bubbles in the propellant collapse and burst rapidly, producing high-frequency sharp sounds; coupled with the turbulent fluid flow in the valve dip tube and the Reynolds number exceeding the stable range, the superposition of the two types of noise forms a harsh noise that damages the user experience. For premium fragrance brands pursuing extreme details, such minor flaws can easily undermine the carefully crafted brand image.
SAILON has been engaged in the R&D and production of custom tinplate aerosol cans for many years. Aiming at the usage scenarios and quality requirements of premium fragrances, we have developed a complete set of solutions for noise-reducing tinplate aerosol cans from three dimensions: fluid mechanics, tank structure and material technology. Every design revolves around the core needs of "silent spray + delicate atomization + stable fragrance output", accurately matching the packaging standards of premium fragrances.
1. In-depth Analysis of Noise Sources: More Than Airflow, but a Synergy of Structure and Pressure
To solve spray noise, we must first identify the core incentives. Through repeated acoustic tests and fluid simulations, SAILON's technical team has sorted out the three main sources of spray noise in tinplate aerosol cans:
- Blast sound caused by cavitation: The pressure drops sharply when the propellant passes through the valve microholes, and bubbles are generated and burst instantly, which is the main cause of high-frequency harsh noise
- Friction sound generated by turbulent disturbance: Unreasonable inner diameter of the valve dip tube and edges at the joints lead to uneven fluid flow rate, and high Reynolds number aggravates noise
- Pressure fluctuation caused by insufficient tank rigidity: Ordinary tinplate material has weak compression resistance, the pressure inside the tank fluctuates during spraying, and the noise amplitude fluctuates accordingly
The appearance of any of these three problems will produce obvious noise. If they are superimposed, it will not only produce harsh sounds, but also lead to uneven atomized particles of fragrance, affecting the uniformity of fragrance output. This is why premium fragrance brands pay special attention to the structural design of fragrance packaging tinplate aerosol cans when choosing packaging.
2. SAILON Core Noise Reduction Technology: All-round Optimization of Silent Effect from Structure to Material
In response to the above noise problems, SAILON has customized an exclusive structural plan for premium fragrance tinplate aerosol cans. Each technical optimization has been verified by actual tests, balancing the silent effect and product practicability:
1. Porous Atomizer Shunting Technology to Disperse Cavitation Blast Energy
Abandoning the traditional single-hole injection structure, a micron-level porous atomization component is adopted to split the concentrated high-speed airflow into multiple fine airflows, disperse the energy of bubble blast, and reduce the peak value of high-frequency noise from the source; at the same time, refine the atomized particles to make the fragrance output more delicate, fitting the usage needs of premium fragrances.
2. Streamlined Dip Tube and Joint Design to Lower Reynolds Number and Suppress Turbulence
Re-calibrate the inner diameter of the valve dip tube of noise-reducing tinplate aerosol cans, optimize the traditional pipe diameter to the range of 1.4-1.6mm, matching the flow rate requirements of premium fragrance propellants; the joints adopt an arc integrated molding process to eliminate dead spots of fluid flow, control the Reynolds number within 2000, keep the fluid in a laminar flow state, and reduce noise generated by turbulent friction.
3. High-rigidity Tinplate Material Selection to Stabilize Tank Pressure and Reduce Noise Fluctuation
Select thickened precision tinplate material to improve the overall rigidity of the tank, ensuring that the pressure inside the tank is stable in the reasonable range of 3.8-4.2bar during the whole spraying process, avoiding large and small noise caused by pressure fluctuation; at the same time, the airtightness of tinplate is better, which can protect fragrance raw materials for a long time and prevent fragrance volatilization and component oxidation.
4. Built-in Buffer Diversion Structure to Weaken Airflow Impact Noise
A micro diversion buffer is added at the joint of the valve and the tank to further slow down the airflow injection speed, making the spraying process softer, reducing noise and avoiding splashing of fragrance liquid, improving the usage texture.
3. Actual Test Comparison of Silent Effect: Core Differences Between Traditional Cans and SAILON Custom Cans
Based on the latest acoustic test data in 2026, we conducted multiple tests on ordinary tinplate aerosol cans and SAILON premium fragrance tinplate aerosol cans, and the results are as follows:
| Test Item | Traditional Tinplate Aerosol Can | SAILON Custom Noise-reducing Tinplate Aerosol Can | Actual Optimization Performance |
|---|---|---|---|
| Spray Peak Noise | 69-73dB | 47-51dB | Noise reduced by about 22dB, no sharp harsh feeling |
| Fluid Reynolds Number | 2400-2600 | 1800-1950 | Stable laminar flow state, turbulent noise basically eliminated |
| Tank Pressure Fluctuation Value | ±0.8bar | ±0.2bar | More stable pressure, minimal change in noise amplitude |
| Atomized Particle Diameter | 16-32μm | 6-13μm | Finer particles, significantly improved fragrance output uniformity |
| Brand Sensory Score | 6.2 points (full score 10 points) | 9.1 points (full score 10 points) | Significantly improved recognition of high-end texture |
4. Frequently Asked Questions (FAQ)
Q: Will customizingnoise-reducing tinplate aerosol cansaffect the spray volume and discharge stability of fragrances? No. While reducing noise, SAILON's structural design will accurately match the viscosity of fragrance raw materials and propellant ratio. By adjusting the atomization aperture and diversion angle, it ensures stable single spray volume and uniform discharge without broken spray or leakage, fully adapting to the mass production needs of premium fragrances.
Q: Can SAILON customize the exclusive structure ofspray silent tinplate aerosol cansaccording to different fragrance formulas? Yes. We support one-to-one structural customization. We will adjust the valve dip tube size, number of atomization holes and tank pressure parameters according to the raw material composition, viscosity and propellant type of fragrances, create exclusive custom tinplate aerosol cans to ensure that both the silent effect and user experience meet the standards.
Q: Will the noise reduction process offragrance packaging tinplate aerosol cansincrease production cycle and quality control difficulty? We have realized large-scale mass production of noise reduction structures. Mature mold technology and automated production lines will not extend the delivery time; at the same time, each batch of tinplate aerosol cans will undergo three quality controls: acoustic test, pressure test and sealing test to ensure unified product quality and meet the needs of large-volume supply.
Q: Can this silent can be adapted to other fine daily chemical products besides premium fragrances? Of course. This noise reduction structure is also suitable for high-end hair care sprays, body fragrances, space fragrances and other products. SAILON can adjust the tank specifications and internal structure according to the characteristics of different products to create an adapted tinplate aerosol can packaging plan.
