IMD Chinese name: in-mold decoration technology, also known as paint free technology. In-mold Decoration, IMD is the international popular surface decoration technology. The surface hardened transparent film, the intermediate printed pattern layer, the back MOLDING layer, the oil IN MOLDING LABEL ink middle, can make the product prevent the surface from being scratch and friction, and can keep the bright color is not easy to fade for a long time.

Traditional plastic processing technology has gradually been unable to meet the needs of the new era, light, thin, short consumer electronic products and the rise of environmental awareness,IMD technology is born on this basis. Due to its many advantages, IMD is suitable for 3C, household appliances, LOGO boards and plastic products of automobile parts, especially the popular mobile phone case and various instrument panels. For this reason, many materials in the world, such as Bayer in Germany, GE in the United States, Japan and South Korea, are investing a lot of manpower and materials in the research and development of new materials suitable for this process. Every year, there are a lot of functional film and ink materials.

(IMD) mold decoration is a relatively new automatic production process, compared with the traditional process (IMD) can reduce the production steps and reduce the disassembly components, so it can save time and cost in rapid production, but also has the advantages of improving quality, increasing the complexity of the image and improving the durability of the product applied in the appearance of the product. (IMD) is the most efficient method at present. It is printed on the surface of the film, high pressure molding, punching, and finally combined with plastic molding, eliminating the secondary operation procedures and human hours, especially in the need for backlight, multi-curved surface, imitation metal, hairline processing, logical light, rib interference... Such as printing spray painting process can not be processed, but also the use of IMD process.

(IMD) in-die decoration can replace many traditional manufacturing processes, such as thermal transfer printing, spraying, printing, electroplating and other appearance decoration methods. Especially need a variety of color image, backlight and other related products.

IMD includes IML,IMF, and IMR

IML: No stretch, small surface, used in 2D products.

IMF: IN MOLDING FILM (suitable for high tensile products, 3D products);

IMR: IN MOLDING ROLLER (The film is removed from the product surface, leaving only the ink on the product surface.) ;

IML, difference between IMF and IMR (whether a thin film is left on the surface).

Advantages and disadvantages of IML process

Advantages:

Advantages of IMD/IML products:

1, scratch resistance, strong corrosion, long service life.

2. Good three-dimensional sense.

3. Strong dustproof, moisture-proof and deformation resistance.

4, color change, design change at will.

Main features:

1. From sheet printing and forming, mold design and production to injection molding,

2. Greatly reduce research and development time to ensure punctual delivery;

3. Flexible design, fast diversification of products at low cost;

4. No panel paste, does not contain any volume glue, meet the requirements of environmental protection;

5. The key can realize the bulge in the mold injection molding, and the key life can be hit 1 million times; Achieve high precision decoration of three-dimensional surface, decorative pattern hidden, never wear (unless damaged); 6

Higher scratch resistance and light transmission, easy to achieve permanent clear display;

7. Highly integrated, save the subsequent assembly process, fast assembly, improve the qualified rate;

8.3D molding, so that complex components can also achieve high level decoration;

9. To the end user more beautiful, lighter, more solid, more choices, more safety. Application: Widely used in all kinds of products, such as household appliances, computers and peripheral products, mobile communication terminal products, automobile industry, etc.
