Automatic spraying, making perfection possible
The necessity of spraying insulation cups is mainly reflected in the following aspects:
1. **Enhanced thermal insulation performance**: The thermal insulation effect of insulation cups relies on their structural design, including the vacuum layer and the reflective layer. Spraying can form a protective film on the surface of the insulation cup, further reducing heat radiation and heat convection, thus improving the insulation effect. For example, the outer wall of the inner liner is polished, copper-plated and silver-plated to reduce heat radiation to the outside.
2. **Enhancement of durability**: the spraying process can enhance the wear and corrosion resistance of the surface of the insulation cup. Such as plastic spraying (powder coating) process, due to its strong electrostatic adsorption, high material hardness, making the surface of the insulation cup more wear-resistant and impact-resistant.
3. **Improve the appearance of texture**: spraying can provide insulation cups with a variety of colors and texture of the external surface, to enhance the aesthetics of the product, to meet the personalized needs of different consumers. For example, the PVD process can make the surface of the insulation cup to achieve high brightness mirror effect, and even gradient color rainbow effect.
4. **Protection of the inner liner material**: Insulated cup liner is usually made of stainless steel and other metal materials, spraying can provide an additional protective layer for the liner, preventing direct contact between the liquid and the material, reducing the possibility of chemical reaction, and prolonging the service life.
5. **EASY TO CLEAN AND MAINTAIN**: The protective layer formed by spraying is usually easy to clean, which helps to keep the insulated cups in a hygienic condition and also reduces the maintenance cost.
6. **Provides additional functions**: Some sprayed materials may have special physical or chemical properties, such as anti-bacterial, anti-ultraviolet, etc., which can be used as additional functions of insulation cups to enhance the market competitiveness of the products.
In summary, spraying of insulation cups not only enhances the insulation performance and durability of the product, but also improves the appearance and texture, protects the liner material, as well as provides a surface that is easy to clean and maintain, enhancing the market appeal of the product.
