The atomized particles are fine and stable, and the coating is light, thin, and flat with controllable thickness, eliminating problems such as thick edges, thin areas, sagging, orange peel, and particle agglomeration; The coating is dense without pinholes, effectively improving the functionality of anti sticking, thermal insulation, anti-corrosion, conductivity, hydrophobicity, etc. The finished product has a high-end appearance and stable performance.
Ultra high coating utilization rate, significantly reducing costs without high-pressure strong spraying, no lateral splashing, pure atomization soft material falling, material utilization rate can reach over 90%, saving 60% -75% of coatings compared to traditional spraying, especially suitable for high priced raw materials such as anti stick coatings, high temperature resistant coatings, conductive slurries, special anti-corrosion coatings, etc. Long term mass production effectively compresses consumable costs, reduces waste emissions, and is environmentally friendly.
Low pressure non-destructive spraying, tin foil does not deform, and the entire process is low-pressure non-contact atomization spraying with extremely low impact force. When facing ultra-thin tin foil, soft aluminum foil, and easily wrinkled thin substrates, it will not cause dents, punctures, wrinkles, or tensile deformation, fully protecting the original appearance of the substrate and adapting to continuous production of ultra-thin flexible aluminum foil.
Accurate thickness control, customized film layer according to needs, supporting precise control of nanometer to micrometer level coatings, can achieve ultra-thin single-layer coating and multi-layer composite coating, can meet different process requirements such as surface hydrophilicity and hydrophobicity, and has strong formula adaptability.

Help! Tin foil spraying saves over 70% of material, and Shanghai Yangmi's ultrasonic technology is too advanced
Still being driven crazy by tin foil spraying?! Making food packaging tin foil, uneven spraying leads to poor anti sticking effect, and customer complaints continue; When coating industrial aluminum foil, there are frequent omissions and pinholes, and the product is directly scrapped; What's even more troublesome is that traditional air spraying wastes a lot, with precious metal coatings being discarded in half, and the impact force of high-pressure spraying causing ultra-thin tin foil to wrinkle into a ball. This not only consumes materials and labor, but also burns money if the quality is not up to standard. Who in the industry understands this kind of internal friction 😭
Don't panic! Shanghai Yangmi ultrasonic tin foil spraying black technology directly breaks the industry's difficulties and turns the "pain point" of tin foil spraying into a "pleasure point"! Unlike the rough atomization of traditional spraying, Yangmi adopts high-frequency ultrasonic atomization core technology to instantly atomize the coating into uniform and delicate micrometer sized droplets, with a more uniform and delicate atomization effect, solving the problem of uneven coating thickness from the root. The thickness accuracy of the coating is strictly controlled within ± 2%, and the surface presents a mirror level smoothness without any orange peel, pinholes, or sagging. The adhesion of the coating is directly fully stretched, whether it is a food grade anti sticking coating or an industrial grade insulation and conductive coating, it can achieve a dual line of appearance and strength.
More considerate is the low-pressure soft landing design, completely bidding farewell to the "violent impact" of traditional high-pressure spraying! Zero impact and zero damage are achieved for ultra-thin tin foil. During the spraying process, the tin foil is always smooth and flat, without deformation, wrinkling, or perforation. It is perfectly compatible with flexible substrates such as food packaging tin foil and industrial aluminum foil of various thicknesses, and no longer has to worry about scrap caused by substrate damage. What's even more impressive is that the zero splash spraying mode allows the paint utilization rate to skyrocket to 90% -95%, saving more than 70% of raw materials compared to traditional air spraying, especially precious metal coatings. One spray can save a lot of costs, and the cost reduction effect is visible to the naked eye after long-term use!
Not only does it save materials, but it also maximizes efficiency and stability! The digital precision thickness control system can freely customize coating thickness from nanometer to micrometer levels according to the needs of different industries and products. The operation is simple and easy to understand, and it can be easily mastered without the need for professional technicians. The fully automatic continuous operation mode eliminates the need for manual operation, directly increasing spraying efficiency by three times. During mass production, the coating consistency is extremely high, with zero deviation and full yield, completely solving the problem of unstable mass production. At the same time, there is no dust pollution throughout the entire process, reducing VOC emissions, fully complying with food grade and industrial grade production environmental standards, and making compliant production more worry free!
