IMD process ---- In-mold decoration embedded injection molding technology, in-mold injection molding is a relatively new panel processing technology. Starting from the early 1990s, it has developed from a bonding structure of double-layer film to a three-dimensional molding technology of injection molding with multi-structure, and has now become a popular nameplate technology. It has changed the rigid pattern of flat panels, evolving into a combination of film, printed graphics, inks, and resin injection molded together, embedded in the injection mold cavity and then molded. The injection resin combines with the ink layer on the back of the film, placing the panel graphics and labels between the film and the injection molded resin, ensuring that the graphics and labels do not wear out due to friction or time.
It relies on injection molding, maintaining stable shape and size, making it easier to assemble. Therefore, IMD technology is often used in automotive, communication, electronics, electrical appliances, instruments, and equipment panels, combining decoration and functionality. IMD products feature exquisite decorative graphics and labels that are embedded and not subject to wear from friction or chemical corrosion. ※ Graphics, in-mold injection labels, and color designs can be changed at any time without replacing the mold.
1. For products with three-dimensional shapes, the printing accuracy is precise, with an error of +0.05mm. It can provide light transmission and high transparency effects for graphics and labels.
2. The functional key bubbles are uniform, have a good tactile feel, and can last over 1 million presses. The three-dimensional variation increases the designer's freedom in product design.
3. Composite molding processing achieves a seamless effect. IMD/IML application fields include home appliances: control decorative panels for rice cookers, washing machines, microwave ovens, air conditioners, refrigerators, etc.
Electronics: decorative shells, colored shells, and labels for MP3s, MP4s, calculators, VCDs, DVDs, electronic notebooks, digital cameras, etc.; Automotive: dashboards, air conditioning panels, interior parts, headlight housings, logos, etc.; Computer industry: keyboards, mice, shells; Communication industry: mobile phone keys, mobile phone lenses, mobile phone colored shells, PHS and fixed telephone panels, window lenses; Other industries: medical devices, cosmetic boxes, decorative boxes, toys, sports and leisure products, etc. Development prospects of IMD technology Currently, IMD in-mold decoration embedded injection molding technology is widely used in communication, home appliances, electronics, automotive, instruments, medical devices, toys, cosmetics, and other industries. It is a brand new plastic decoration technology. It can change in three dimensions, increasing the designer's freedom, allowing for the design of various personalized shapes. In-mold injection molding meets the demands of the times.
IMD technology can achieve integrated injection molding and decoration in one step, and can create various special effects, such as: key bubbles, metal mirror or matte surfaces, metal brushed textures, light transmission, and embossed patterns, etc., which are highly decorative and functional. IMD technology is the best new process to replace the painting and electroplating of plastic products, reducing subsequent processing steps of injection molding, promoting and popularizing in the plastic industry, truly achieving energy saving and environmental protection, and bringing huge economic and environmental benefits to society and enterprises. IMD is the technology of placing pre-printed decorative sheets into the injection mold, and then injecting resin on the back of the formed sheet, allowing the resin to bond with the sheet to solidify and form a unit. The IMD process is a technology that adds decoration while injection molding, where the product is combined with the decorative substrate, allowing for decorative printing on three-dimensional molded products, achieving both decorative and functional effects.
