A brief introduction to IMD/IML

Release time:2018-08-06 丨Company News

1. Definition of IMD

IMD Chinese name: In-mold decoration technology, English name: In-Mold Decoration, IMD is the current international surface decoration technology, surface-hardened transparent film, intermediate printing pattern layer, back injection layer, ink in the middle, can prevent the surface of the product It is scratched and rubbed, and it can keep the color bright and easy to fade for a long time. IMD includes IML, IMF, and IMR.

IML: IN MOLDING LABEL [no stretch, small surface for 2D products]

IMF: IN MOLDING FILM [suitable for high tensile products, 3D products]

IMR: IN MOLDING ROLLER [The product surface film is removed, leaving only the ink on the surface of the product. )

IML, IMF (currently known as IML in the industry and IMF) differs from IMR in whether or not a film remains on the surface.

Traditional plastic processing technology has gradually failed to meet the needs of the new era. Lightweight, thin, short consumer electronic products and environmental awareness are on the rise. IMD technology is born on this foundation. Because the advantages of IMD are suitable for plastic products of 3C, home appliances, LOGO nameplates and auto parts, especially the current popular mobile phone case and various instrument panels.

IMD in-mold decoration is a relatively new automated production process. Compared with other processes, IMD can reduce the production steps and reduce the components of the disassembled parts, so it can save time and cost quickly, while also improving the quality and increasing the image. The complexity and durability of the product are applied to the appearance of the product. IMD is currently the most efficient method. It is applied on the surface of the film by printing, high-pressure molding, die-cutting, and finally combined with plastic to eliminate secondary operations. The program and its man-hours, especially when it is necessary to use backlighting, multi-surface, imitation metal, hairline processing, logic light pattern, rib interference, etc., can not be processed, it is the time to use IMD process.

IMD in-mold decoration can replace many traditional processes, such as thermal transfer, painting, printing, electroplating and other decorative methods. In particular, it requires a variety of color images, backlights and other related products.

2, the concept of IML

IMD (In-Mold Decoration) is a new technology that places a Film film in an injection mold to decorate the surface of a plastic surface. At present, IMD has two manufacturing methods. One is to make a printed Film film into a circulating drum roll, which is installed in an injection molding machine and an injection mold. The label Label is attached to the front mold surface and fully automatic. Production is known; that is, people call it IMD (transfer injection molding in the mold).

The other is to print the Film film through Forming molding, and then cut it and put it into the injection mold to produce it. It is called IML (film injection molding in the mold). This Film can generally be divided into three layers: substrate (usually PET), ink layer (INK), and glue (mostly a special adhesive).

When the injection molding is completed, the film and the plastic are tightly combined by the action of the adhesive. Because the PET with the wear-resistant protective film on the outer surface is in the outermost layer, it has the functions of abrasion resistance and scratch resistance, and the surface hardness can be It reaches 3H, and it will be brighter and brighter.

3. Process characteristics of IMD/IML

IMD/IML products have the advantages of high definition, good stereoscopic effect, scratch resistance on the surface, freely change the design pattern, enhance the appearance of the product, and reflect the perfect profiled structure. It is widely used in mobile phone lenses, casings, etc. 3D The appearance of the styling product. Solve the special shape effect and multiple colors that can not be achieved by acrylic plates in the past.

IMD/IML technology: a new in-mold decoration technology combining screen printing, molding and injection molding. In-mold decoration (IMD/IML) is the most effective and cost-effective method for decorating products. Used in communication products (such as: mobile phone / PHS lens, decorative parts, housing, etc.), household appliances (window panels, button panels, decorative panels, etc.), medical equipment (window lenses, chassis, decorative parts, etc.) and automotive instruments plate. Diversified applications have made in-mold decoration an ideal replacement for many traditional processes: traditional methods such as thermal transfer, direct surface printing, surface coating, direct plating, two-color injection molding. It is best suited for 3D products, especially for consistent color patterns, backlights, multiple colors, and on a variety of curved, curved, and beveled surfaces.

Advantages of IMD/IML products:

1. Scratch resistant, highly corrosive and long service life.

2, the three-dimensional feeling is good.

3, dust, moisture, anti-deformation ability.

4, the color is arbitrarily changed, the pattern is free to change.

 Main features of IMD/IML:

1. From the printing and forming of the sheet, the design and manufacture of the mold to the injection molding, the entire manufacturing process is completed by our company;

2. Minimize development time and ensure on-time delivery;

3. Flexible design and rapid product diversification at a lower cost;

4. No need to paste the panel, do not contain any plastic agent, meet the environmental requirements;

5. The button can realize the protrusion during the in-mold injection, and the life of the button can be played 1 million times; realize the high-precision decoration of the three-dimensional surface, the decorative pattern is hidden, and never wear (unless destroyed);

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

7. Highly integrated, saving subsequent assembly processes, quick assembly, and improving the pass rate;

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

9. Make the end user more beautiful, lighter, more solid, more choice, and safer. Application areas: Widely used in various products, such as household appliances, computers and peripheral products, mobile communication terminal products, automotive industry, etc.

Advantages of IMD/IML:

1. Product stability: the correct color registration that makes the product consistent and standardized;

2, product durability: through the special treatment of COATING film protection, can provide better surface wear and chemical resistance;

3, 3D complex shape design: the application of the excellent stretchability of the film, can smoothly achieve the required product complexity and open design requirements;

4, diversified style: can be created according to customer needs metal plating or natural material special style.
