IML/IMD introduction: IMD (In Mold Decoration) is a kind is placed In the injection mould to decorate the plastic Film Film appearance on the surface of the new technology. It has a bright and clean appearance, permanent clear printing, 3 d design stereo incomparable advantage over traditional plastic screen printing.
In science and technology leading the fashion trend, the aesthetic and the use value of the requirements are constantly improve, including the ratio of volume and weight also have very high demand, so have to a large number of using plastic, 60% of the items in our daily life is plastic, and the appearance of the plastic lasting protection has been a difficult problem? The answer out of IMD technology is undoubtedly a good opportunity!
Here I talk a ` advantages and prospects of IMD IMD process across multiple fields, have chemical ` printing ` mechanics ` ` injection mold. So there are must master the technology for more than a few fields has a very deep understanding and the exquisite technology, can be different process cohesion, make different IMD arts and crafts.
Process: IMD technology is the ink overprint in the LONS through mold processing surface, layer upon layer on top of each color has a beautiful pattern, (because the print is so if you're willing to put your photo above), and then calculate the LONS tensile ratio high pressure molding (prior to the product of the shape of this machine recommended qiaolian machine), put them in the injection mould for plastic injection, after the injection is a fine plastic products, don't need to printing, spray, coloring and other ways.
Advantages: LONS sheet printing and injection will ink caught in the middle of plastic raw materials, after the appearance form a solid shield (the hardness of the 3 h), can withstand the general hardness of medium the frequent friction on its appearance, not scratched ` won't rub off, using a special printing plate can also improve the impact resistance, if use electrical appliances or other control panel on the touch-key usage can reach 2 million times and not burst.
Advantages of the above products have been widely used in plastic products, application areas have MP3 ` mobile ` handheld PDA ` ` automobile appliance ` fitness equipment nameplate ` instrument, etc., so the corresponding has a broad market and huge profit space, and in the plastic market IMD technology will be used on plastic appearance of preferred process, reform will bring about a new appearance storm and has been its potential!
IMD production process specific subdivided into:
1) cutting material: cut rolls of Film Film has good design size square piece, in preparation for printing process.
2) preshrinking: good cutting Film Film before printing in the oven heat shrink to minimize the chance.
3) print: according to the requirements of the ICONS and text made into a Film, on the square piece cut out good Film Film printing icon and text.
4) ink drying is fixed: the square piece of printed Film Film placed in high temperature oven drying, the purpose is to thoroughly curing IMD inks, ink solvent in steaming.
5) stick protective Film: avoid rush in positioning hole process with flowers has printed Film Film surface, sometimes need to put a single or double protective Film.
6) blunt positioning hole: shear process and hot forming process of positioning hole must be crossroads.
(7) high pressure or copper) : the printed film after heating, with high-pressure machine or copper molding in preheating condition. The design of the Forming Mold is the key. (note: IMD products molding preferable cutting peripheral, film can be saved.) - dongguan bridging mechanical compression machines are highly recommended shape
(8) shear periphery to forming good stereoscopic film scrap shear off. Requires accurate shearing mould.
(9) injection: after the molding and mold three-dimensional shape of the same film placed on the front mold, injection molding the IMD finished products.
