It refers to in-mold decoration technology, also known as paint-free technology. English name: In-Mold Decoration, IMD is the international popular surface decoration technology, surface hardening transparent film, the middle of the printing pattern layer, the back of the injection layer, the middle of the ink, can make the product friction-resistant, to prevent the surface from being scratched, and can be maintained for a long time the color of the distinctive is not easy to fade.
(IMD) in-mold decoration is a relatively new automated production process, compared with the traditional process (IMD) can reduce the production steps and reduce the disassembly of the constituent parts, so it can be quickly produced to save time and cost, but also has to improve the quality, increase the complexity of the image and improve the durability of the product advantages of the application of the product appearance.
Expanded Information
IMD field of application
IMD is used in a wide range of fields, at this stage used in cell phones, white goods industry, the future will be developed to anti-counterfeiting marking, automotive industry. Its products have a good performance of sunscreen, can be used for automotive signage, etc.; hardness up to 2H ~ 3H, can be used for cell phone lenses, etc.; key life of up to 5 million times or more, can be used for rice cookers, etc..
IML product testing and inspection
IML products have passed the following tests, which all meet the requirements.
1, hardness test: with a sharpened 2H ~ 3H pencil attached to the force of 500g, at an angle of 45 degrees to the surface of the product pushed flat, the surface of the product without obvious scratches and scratches as a pass.
2, temperature test: the product will be placed in the relative humidity of 95% ~ 100%, the temperature of 57 ± 3 ℃ furnace for 48 hours, no cracking, discoloration, deformation, color, loss of function and other phenomena is qualified.
3, wear test: rubber against the product surface weight 500g, in the same position 2 inches long back and forth friction 300 times (a back and forth for a time), the surface of the bottom is not obvious as qualified.
