• Classification of silicone key printing defects and solutions

  2022 / 10 / 09

  Silicone keys are widely used, not only for TV, air conditioner and other remote controls in daily life; Mobile phones, small appliances, cars and other buttons are also common. They all need to use surface screen printing to screen characters. If there is production, there will be defects. What are the defects of these silicone key screen printing? How did they come into being? How to solve it? 1. Silica gel printing is simply to say that the screen printing method is used. The screen printing part of the screen can pass through the silica gel printing ink, and the screen printing part of the screen can not pass through the silica gel printing ink. The basic principle of printing is that the screen printing part of the screen can not pass through the silica gel printing ink. Use the squeegee soft scraper to apply a certain pressure on the screen, so that the silica gel ink can be squeezed from the screen holes of the graphics and text part to the surface of the silica gel keys. 2. The silicone key printing generally has these defects through classification: deviation, oil accumulation, dirty screen, diffusion, color difference, pinhole, thin oil (pitted surface), ghosting, burr (saw edge), deformation, missing printing and poor adhesion; 3. The causes and treatment methods of various defects are as follows: 1. Position deviation. The reasons for position deviation are: a. The film is inconsistent with the fixture; b. The fixture is too loose, and the key is on the side; c. The fixture is too tight, and the key cannot be covered when printing; d. The tension of the screen is unstable or the screen and the screen frame fall off slightly or are damaged slightly; The above defects can be solved by adjusting the film fixture. 2. There is oil accumulation, which is caused by: a, the key surface has radian, the net spacing is too high, b, the key surface has radian, and the rubber scraper pressure

• How to make a good start in silicone key production

  The customization of silicone keys starts from the material preparation and molding process. The efficient production of the first stage process not only lays a solid foundation for the processing of the later stage process, but also is an important guarantee for the delivery of silicone products. Today, we would like to share how the molding department makes a good start in the production of silicone keys. 1. Silicone keys mainly include: mobile phone keys, remote control keys, calculator keys, telephone keys, computer keyboards, digital products, automobile products, etc! 2. Employees shall be trained according to different classifications, and products that need printing, spraying, radium carving, dispensing, assembly and other back-end processes for continuous production shall be processed directly for quality assurance and shipment by classified production. Put forward different variety control requirements for products with different requirements for training, such as: black grain, mold surface, pinhole, immature, lack of materials, sticky raw materials, etc; 3. The selection of raw materials, color pastes and vulcanizing agents for products with back-end processes shall consider the high temperature resistance of back-end processes; 4. Employees must hold cards for production, operate according to the cards, define the standard capacity target and the scope of bad control, and give extra rewards according to performance for the part exceeding the capacity; 4. Require employees to "do first, look second, and follow up third" First, it means that the on-site team leader should first operate it to show the employees, let them know the production conditions, quality requirements, production skills, etc. of the silicone keys, and let them quickly understand, so that they can quickly put into efficient production status; Second look: it means that the on-site te
