Character keys on the surface of silica gel Making
Character keys on the surface of silica gel generally produced the following methods:
1. Screen printing: a printing surface and the bottom printed, printed, when the general first spray the surface of the keys, then the above screen fonts and symbols, and then sprayed to protect the oil. Indian bottom keys are generally transparent, hollow words, screen printing and screen printing cover solid background color background color font cover two. For keys that arc larger printing method can be used in the steel on the corrosion out of the font, with plastic head and the ink pad to the button surface, printing a lot of used in the toy industry.
2. If the character requires translucent effect, most of the spraying and laser engraving is the method, after injection transparent button in the button's surface spray ink, and then a laser can be laser light transmission of the characters, then a layer of protection oil spray can. For requirements, see the red symbol, you can start printing at the top of the red button, need to print the entire surface, then spray the surface of the ink destroyed see red, the color similar to the other.
3. Need to effect the key can do electroplating electroplating and vacuum plating of water, and now need to do a lot of the direction buttons on the effect of yin and yang patterns generally do electrical mold, as it is out of the boundaries clear, beautiful appearance, is directly on the texture on the mold can not be present be achieved. Two-color injection molding is generally used in a button on the need for light and plating of the keys, PC is not on the plating, abs can plating, two-color injection molding requirements of injection molding is to pc and abs together, where abs after plating is the plating results, the pc can be part of the light transmission. Vacuum plating is also the symbol can be made translucent, but the effect of vacuum plating compared the feeling of floating people, there is no effective electroplating.
Phone keypad is usually carved surface mine in the paint surface of buttons for text processing approach. Generally the size of diameter 0.04-0.06, and then we will use interval 0.04-0.06 text line fill. So that we give a path of laser developed. Laser engraved with the path to the paint off on it.
If you want to do laser engraving, and very importantly, faster, just fill in the method is not enough, another approach is to go with the CNC laser is given as the path, so to come to the border would be more clear, because triggered when the laser energy at large, will lead to bowel problems and border appear jagged wear.
IMD's Chinese name: injection surface decoration technology that IMD (In-Mole Decoratiom), IMD is the international popularity of the surface decoration technology, mainly used in home appliance products, decorative and functional surface panels used in mobile phones window lens and housing, washing machine control panel, refrigerator control panel, air conditioning control panel, automobile instrument panel, electric cooker panel control panel variety of areas, signs and other exterior parts on.
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's Chinese name: injection mold inserts their craft very significant characteristics: the surface is a layer of hardening of the transparent film, the middle layer of the printing pattern, the back of the plastic layer, due to ink in the middle, can prevent the surface of products scratches and abrasion, and may long remain distinct colors fade easily.
IMR's Chinese name: Mold Roller
This process is pattern printed on film, through the diaphragm to send film machine will fit with the plastic model of cavity injection molding, injection molding pattern after the ink layer and membrane separation, ink layer remain in the plastic parts on the surface of the decorative patterns are The plastic parts, in the final product is not a transparent surface protective film, diaphragm is a carrier of the production process. However, the advantage of health IMR barium Nao far Lake Bird Yao Ji pain can embarrassment of a system to kill the shortcomings of the Ting MR: printed pattern layer in the product's surface, only a few microns thick, the product used for some time will be printed after the pattern layer is easy to wear out, but also easy to fade, causing the surface is very beautiful. Another new product development cycle is long, high development costs, design flexibility in small batches to achieve the color change can not also IMR technology can not overcome the weaknesses.
