Polycarbonate film in IMD film decoration process application share!

IMD is the general name of the mold decoration process, common IML, IMF, IMR, IMT, INS, etc., generally speaking, the film is printed and other surface treatment, and then put into the mold for injection molding, which is a molding and surface treatment integration process, a combination of product design, mold technology and traditional post-processing technology as one of the process technology.  picture

 

IMD products with high clarity, good three-dimensional sense, surface scratch resistance, can change the design pattern at will, enhance the beautiful appearance of the product, reflect the advantages of perfect shape structure, can also be combined with flexible circuits, integrate the atmosphere light, display and other functions, widely used in automotive interior and exterior decoration, home appliances, mobile phone/laptop shell and other products with high appearance demand.

The film layer material of IMD process should have excellent comprehensive properties, such as impact resistance, chemical corrosion resistance, wear resistance, easy formability, high transparency, temperature resistance, high tensile and printability.  At present, there are mainly PET, PMMA, PC, PC/PMMA and other materials.

 

• PET film: Usually the film layer material used in the IMD process is generally PET, but the formability of PET is poor, and the deformation of the film is serious after forming, and only the shallow formed products of IMD can be made.
• PMMA film: as a film layer material, it is difficult to form a film with large curvature radius and complex structural characteristics because of its great brittleness;
• PC film: due to its excellent comprehensive performance, it has high impact strength, bending resistance, low water absorption, good dimensional stability, heat resistance, low temperature resistance, excellent printing performance, etc.  At the same time, it can improve its stress, wear resistance, flame retardancy and other properties by blending modification, and is widely used in the field of IMD.
• PC/PMMA composites: Combining the high impact strength and bending resistance of PC materials with the hardness and wear resistance of PMMA materials, the material has toughness, superhard, wear resistance, high transparency, gloss and excellent electrical insulation, which can meet a variety of high pressure and hot press IMD/FIM processes.

Dobesty film has good processability, excellent formability and dimensional stability, high printing performance, through the perfect combination with in-mold decoration (IMD) and film insert molding (FIM) can provide surface design and durability for products, making personalized innovative design possible, has been widely used in automotive interior and exterior decoration, home appliances and other fields.
