Which two processes are used in the manufacturing process of this cordless smart vacuum cleaner to improve the texture of the product?

In the manufacturing process of this cordless smart vacuum cleaner, the two major technologies of UV engraving and car paint craft are cleverly integrated, and the appearance texture and durability of the product are comprehensively improved with an attitude of excellence, bringing consumers a beautiful and practical household cleaning tool.
As an advanced manufacturing method that combines modern optical and precision mechanical technology, the UV engraving process has indeed brought an unprecedented visual and tactile experience to the V70 cordless smart vacuum cleaner. This process uses the high energy density characteristics of ultraviolet laser beams to achieve micron-level or even nano-level precise engraving on the surface of the material, and its high precision is almost comparable to the microscopic world of nature. In the design of the V70 vacuum cleaner, the UV engraving process is not only limited to outlining simple and clear lines, but also boldly tries complex and varied patterns, delicate textures, and fine three-dimensional relief effects. These design elements not only make the surface of the vacuum cleaner shell clear and rich in details, but also show a flowing beauty between the interweaving of light and shadow, as if each work is a unique art treasure.
UV engraving not only enhances the aesthetic value of the vacuum cleaner, but also contributes to its practicality. Through fine engraving, the microstructure of the surface of the vacuum cleaner shell has been optimized, increasing the friction when in contact with the user's hand, making the grip more stable and reliable. This design takes into account the needs of users in actual operation, effectively avoiding accidental falls caused by hand slippage, thereby improving the safety and comfort of operation.
The application of car paint technology is another leap in the quality of the V70 vacuum cleaner. Unlike the simple and rough spray painting of traditional household appliances, the V70 vacuum cleaner draws on the coating technology of the automotive manufacturing industry and adopts a multi-layer coating process, each layer of which is carefully formulated and strictly controlled in quality. The primer layer lays a solid foundation for the entire coating process, ensuring the uniform adhesion and good hiding power of the color paint layer; the color paint layer gives the vacuum cleaner a bright color and vivid texture, making the product more eye-catching; and the varnish layer, as the outermost layer of protection, not only improves the hardness and wear resistance of the surface, but also gives the vacuum cleaner a mirror-like smooth touch, and every touch can feel the delicateness and warmth.
Through the perfect combination of UV engraving and car paint technology, the V70 vacuum cleaner not only meets the needs of modern families for efficient cleaning in terms of function, but also realizes the integration of art and technology in appearance design, becoming a smart home product that can be integrated into various home styles and highlight the owner's taste. Such a design concept is undoubtedly a bold breakthrough in the design concept of traditional home appliances, and it is also an active exploration of the future development trend of smart homes.
