Spray-free materials will become the future development trend?

【China Aluminum Industry Network】Generalized Spray-free: No spraying, environmental protection materials; including: high-gloss spray-free, pearlescent effect, metal texture effects... In order to cater to the demand for colorization and special effects of electronic products, no-spray coating materials with high-light, trace-free spray-free technology have emerged. Spray-free material is a material that can be directly injection molded and can achieve a colorful appearance without spraying. Spray-free materials In 3C such as household appliances, metal effects are usually required. This requires the addition of micron-sized metal powders. However, if metal powders are added directly during injection molding, at least the following problems will occur: 1) Large dust and poor working environment; 2) The metal powder is difficult to disperse uniformly in the plastic; 3) Aluminum metal is chemically active, easily oxidized and discolored; 4) The combination of metal powder and plastic is poor, and it is easy to precipitate on the plastic surface. Why do spray-free materials become the trend of future development? advantage: 1.Direct injection molding, to achieve a special pearlescent, metallic luster, shine, dazzling appearance, without surface modification 2. Can be completely recycled, no pollution, reduce environmental burden 3. One-time molding, eliminating the need for spraying process, without post-processing, reducing unit product cost 4. High degree of design freedom and more flexible parts The following is a comparison of spray-free materials and common materials: In addition, spray-free materials also have the following advantages: 1, rich colors, good weather resistance, not easy to decolorize; 2. The overall cost is low; 3, green, environmental protection and health; 4, brilliant colors can help customers deal with diverse and differentiated market needs. Due to the lack of “painting”, the spray-free materials are more environmentally friendly and have lower costs. Spray-free materials not only meet environmental regulations, protect human health, but also save costs for the company, but also save a lot of trouble. Compared with sprayed products, it is easy to form and has a high yield rate. Products can be recycled and reused without causing harmful gases, dust, and other contaminants. In addition, color helps customers respond to diverse and differentiated market demands. For the material itself, the non-spraying material is 10% more expensive than the normal plastic, but the cost of using the non-spraying material is reduced by 20% to 30% when the paint cost is calculated. In some special cases, such as summer, some spray-painted plastics have particularly high scrap rates. Using spray-free materials may reduce the cost by 40%. The cost reduction means more opportunities in the automotive market. With less paint spraying, it is also possible to eliminate a series of problems brought about by painting, such as the failure of the painting process.
