How to operate silicone keypad screen

1. Screen printing: a printing surface and the printing end, print face when the general first spraying the surface of the button, and then on top of screen fonts and symbols, then spray protective oil. India are generally transparent bottom button, hollow words covers silkscreen printing solid background and font cover background two kinds. For cambered buttons indicate larger printing method can be used in the steel etched font with plastic head to the surface of the ink pad keys, printing in the toy industry with a lot.
2. If the character required light effect, the majority or by spraying and laser engraving method, after injection transparent buttons, the surface coating of the ink keys, and then laser laser that can be opaque character, then spray a layer of protective oil can. For requirements see red symbol, you can start printing the red button at the top, you need to print the entire surface, and then spray the surface of the ink is destroyed see red, similar to other colors.
3. Plating effect of keys required to do water electroplating and vacuum plating, a lot of direction and now needs to be done on the effect of yin and yang lines generally do power button molds, as made out of clear boundaries, beautiful appearance, is the sun directly in the mold pattern can not currently achieved. Color injection molding is generally used in a key need for keys on the transparent and electroplating, PC is not on the plating, abs can plating, two-color injection requirement is that the pc and abs injection molding together, abs place after plating is plating effects, and you can be part pc light. Vacuum plating current can be made opaque symbols, but the effect of vacuum plating people feel more floating, no electroplating good effect.
Phone keypad carving surface mine is usually painted surface in the key word processing approach generally 0.04-0.06 diameter size, and then we will adopt the text line spacing 0.04-0.06 filled so we gave laser developed a path. laser engraved with the path out of paint on it.
??If you want to do laser engraving, and it is important that faster, just fill method is not enough, another kind of way is given with CNC laser as walking path, so to make the boundaries would be more clear, because Laser energy is great when triggered, will bring shock and wear problems appear jagged border.
?IMD's Chinese name: injection surface decoration technology namely IMD (In-Mole Decoratiom), IMD is the international popularity of surface decoration technology, mainly used in surface decoration of home appliances and functional panels, commonly used in mobile phone casing and window glasses, washing machine control panel, control panel refrigerator, air conditioner control panel, car dashboards, rice cookers control panel in various fields panels, signs and other exterior parts.
??IMD is divided into IML, IMR, the biggest difference between these two processes is the product surface is a layer of transparent protective film.
??IML the Chinese name: injection mold inserts its remarkable features is the process: the surface is a layer of hardened transparent film, the middle layer is printed patterns, the back of the plastic layer, since the ink in the middle, the product can prevent surface scratches and abrasion, and maintain long-term bright color not fade.
?IMR's Chinese name: IMD
??This process is the pattern printed on the film, the film by film feeding machine and plastic injection molding fit the mold cavity, after injection patterned ink layer and membrane separation, the ink layer is left on the surface of the plastic parts obtained decorative patterns plastic parts, in the final product is not a transparent surface protective film, the diaphragm is in the process of producing a carrier. But the advantage is that students  barium IMR far  Tan Nao Ji  bird shout pain can kill a  embarrassed Department Ting MR drawback: the printed pattern layer on the surface of the product, the thickness of only a few microns, the product used for some time After easily print pattern layer will wear off, but also easy to fade, causing the surface is very beautiful. In addition, new product development cycle long, high development costs, pattern color change can not be achieved in small quantities flexible IMR process is unable to overcome weaknesses.
