What are the fields of application of silicone keys for equipment

2022-02-22 17:27:59

Characteristics and uses of silica gel Silicone is a kind of rubber. The vulcanized silicone rubber has heat resistance, cold resistance, ozone resistance, atmospheric aging resistance and good electrical insulation properties. The disadvantage of silicone rubber is that the tensile strength and elongation at break are small, and the compression deformation is large. Suitable for making parts used in high temperature, low temperature, sunlight, atmosphere, ozone environment and electrical insulation parts. Dimensional accuracy and recommend marking tolerance Trajectory material is an elastomer, compared to the plastic material, the direct impact of the shrinkage rate of many and complex factors, precision than plastic parts more difficult to do accurate, in the specific design should be fully considered, there should be no high precision. If the basic size is too large to meet the dimensional accuracy required by the design, it can be solved by the method of deformation of the positioning column with the substrate. Where dimensional accuracy is required, there must be room for convenient mold repair in the design. Etched text and patterns Silicone substrate can be designed out of the trademark pattern and text, in the molding products at the same time molding out. The group and text on the products are convex and concave two types, considering the convenience of mold processing, are generally designed as convex. In order to facilitate the replacement of marks or models, the marked parts can be designed as inserts during mold design. When the product model changes, only the marked parts in the mold cavity can be replaced to meet the needs of mark replacement. As part of this type of article, it should be designed to allow the presence of flash debris at the contour of the insert tile at the marked location. For conductive rubber, the stroke is generally 0.8~1.5mm; the exhaust groove (I. e. gas pit) is designed to prevent adsorption between the PCB and the key action. For tact switches, the stroke depends on the stroke of the switch itself (and the stroke for preventing misoperation), as described later. If the substrate is not bonded to the PCB board, the structural element of the air slot can be omitted. The key design has a hand feeling problem. Different graphs correspond to different hand feelings. According to experience, when (FP-FC)/FP is 40%-60%, the hand feeling is better. Key Typical Structure and Application According to the specific occasions where the keys are used, as well as the specific requirements of the product for the service life, pressing force, and hand feeling of the keys, the structure and application of the keys are shown in the following figure. The life of the silicone key is directly related to the material and the inclined wall structure, and is determined according to the design requirements. Part of the product silicone key life reference: Remote controller: 500000 times; Telephone type: 1 million times; Laptop computers: 4 million to 5 million times; Computer keyboard: 500~10 million; The life of silicone keys for monitoring products is defined as more than 500000 times; The ordinary life of B super silicone keys is defined as more than 1 million times,


The convenience of the use of industrial silicone buttons

2022-01-18 18:14:20

In order to solve the above problems and technical defects, after continuous updating and design, a multi-station silicone button trimming machine was invented, and a utility model patent was applied. The utility model relates to a multi-position silicone button trimming machine, which comprises a base, a gantry frame and four cutting cylinders, and the four cutting cylinders are arranged vertically on the top of the gantry frame in a horizontal straight line. The beneficial effect achieved by the utility model is that the structure design is reasonable. By adopting the combination design of four reinforcement tables and four cutting blades on the gantry, the device can simultaneously trim four silicone button products. Thereby greatly improving the efficiency of trimming processing of silicone products. With the continuous expansion of the silicone button market, how to improve the processing efficiency of the silicone button has made producers pay more and more attention. The trimming of the silicone button is an important step in the production process of the silicone button, and the trimming of the traditional silicone button The processing efficiency cannot be improved, which affects the overall production efficiency of the silicone button. Various types of silica gel have different microporous structures due to their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel according to its pore size is divided into: macroporous silica gel, coarse pore silica gel, type B silica gel, fine pore silica gel.


What kind of silicone protective cover is popular

Silicone material transparent, soft, elastic, completely set on the machine, will not affect the control of the machine. In addition, the silicone sleeve is formed through the design of the mold, so the manufacturer will fully consider the controllability to ensure that the silicone sleeve does not need to be taken off from the machine and installed again like a leather sleeve and a cloth sleeve, which greatly facilitates users. In addition, the material used in the silicone sleeve has very good inertness, will not react with any other acid and alkali products under normal conditions, and is waterproof, resistant to high temperature and insulated. Therefore, the silicone sleeve is a good protection device to protect handheld electronic devices. Like mobile phones, tablets, MP4, etc. As an accessory for electronic products, the main function of the silicone sleeve is to protect the surface of the product from scratches and dirt. However, in fact, due to the inconvenience of use, these accessories are often put aside by users, because if you put on a leather case or cloth cover during normal use, it will often affect the normal operation, especially for handheld devices such as mobile phones with key operation, while silicone sleeves just have the characteristics that leather cases and cloth covers do not have. We all know that most of the shell of handheld electronic devices, in order to pursue the aesthetic feeling of the surface, the design mostly adopts rigid mirror plastic shell or metal shell, and in daily use, it often contacts and frictions with clothing desktop or other materials. It won't take long for the surface to produce scratches, serious or even decolorization, so a new machine will soon become old, A device that is as little as a few hundred yuan or as much as thousands of yuan will be greatly reduced due to the wear and tear value on the appearance. Therefore, careful consumers will think of many ways to protect their machines. Before the appearance of silicone sleeves, careful manufacturers Will match these devices with a leather case or cloth cover. The role of silicone protective sleeve 1. Protect the mobile phone to prevent hard objects from leaving scratches on the screen or body of the mobile phone. 2. The mobile phone case can be printed with various colors, which has the effect of beauty. 3, silicone sleeve can prevent the nail for a long time contact with the button scratch, wear, there is a protective screen and the role of the button. 4. The silicone sleeve has a non-slip effect. 5. The Apple mobile phone case also has the function of enhancing the signal, because some mobile phone shells form a magnetic field after contacting with metal, which interferes with the mobile phone signal. Putting an insulated mobile phone case on the mobile phone can enhance the signal. 6. Protect the mobile phone when it is accidentally dropped to prevent it from being broken. 7, modeling mobile phone sets can be dressed up as a variety of personalized appearance.
