1. Spray laser carving The principle of laser processing technology is to project a laser beam onto a material and use the laser to interact with the material to melt, remove, weld the material or change the surface characteristics of the object. When the silicone key product process is spraying, there are mainly three ways to feed glue: direct glue feeding, bottom glue feeding and point glue feeding. ①. Direct glue feeding method When the product is solid and the height is not more than 1.5mm, the inclination of the product is not less than 1.5 degrees, and the product is not allowed to be glued in other ways, the mold adopts the direct glue feeding method. The glue feeding width of direct glue feeding is generally 2.50~3.00mm, the specific glue feeding width depends on the size of the product, the glue feeding thickness is generally 0.30~0.35mm, and the straight body position of 0.35~0.50mm is required to facilitate punching, and the foot column direction on the product frame should be in the opposite direction of the product surface. When the silicone key product is hollow and has a height of 1.8mm or less, and the inclination of the product is not less than 1.5 degrees, the mold adopts the direct glue feeding method. The glue feeding width of the direct glue feeding is generally 2.50-3.00mm, and the glue feeding thickness is generally 0.30-0.40mm. The specific glue feeding width depends on the size of the product, and the maximum straight body position is 0.30mm to facilitate punching, and in order to prevent the product from sticking to the front mold, the hollow glue position part of the product rear mold is generally not drawn, and the foot column direction on the product frame should be in the opposite direction of the product surface. Author: UG Product Design Teaching 2. Back printing For the processing process for the back of the printed key products, its glue into only one way, is directly into the glue way. The glue reducing wave bit should be made at the glue inlet point of the front mold, and the glue reducing depth is generally 0.5mm, which is to avoid scratching the screen plate due to the burr of the glue inlet during printing. The glue reducing wave bit can be made into arc shape and square shape. For the silicone keys printed on the back, the draft angle is generally not less than 1.5 degrees, the glue inlet width is generally 2.5~3.5mm, and the glue outlet width is generally 2~2.5mm. The glue inlet and outlet position is generally 0.~ 0.5mm straight extension to facilitate punching. The glue inlet and outlet thickness is generally 0.3~0.4mm, and the specific value is determined according to the size and height of the key product. And the direction of the foot column on the frame should be consistent with the surface direction of the key product. 3. Electroplating Plating is the process of using the principle of electrolysis to plate a thin layer of other metals or alloys on some metal surfaces. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation (such as corrosion), improve wear resistance, conductivity, reflection, corrosion resistance (copper sulfate, etc.) and improve appearance. For silicone key products with electroplating processing technology, the glue feeding method is generally direct glue feeding method and bottom glue feeding method. There is no difference between the characteristics of the glue feeding method of electroplated silicone key products and the glue feeding characteristics of sprayed key products. The size of the glue feeding point is generally 0.6 ~ Ф 0.8mm in Ф, the inclination of the glue feeding column is generally 6-8 degrees, the front mold of the key is provided with a mold, and the glue feeding point of the front mold surface is generally 0.3~0.5mm in depth, this is to prevent the glue injection point from being injured if the product needs to be lowered when the mold is changed in the future. www.mingzhen2006.com

The main uses of silicone rubber products are as follows: 1, the use of silica gel has a strong adsorption can quickly and effectively absorb the moisture in the sealed package, chemical stability, non-toxic harmless characteristics; coupled with continuous innovation and development in recent years, a variety of silica gel has been widely used in drug purification, DNA separation, food drying, high-precision electronics, advanced cosmetics, sewage purification, beer purification, advanced coatings and resin production or preservation, with the development of industry, silica gel has also been made into various industrial protective articles. 2, can be used for medical equipment accessories, due to the characteristics of colorless, odorless and non-toxic silica gel is widely used in the medical industry. 3. It can be used for the reproduction and manufacture of a large number of soft mold materials for cultural relics, handicrafts, toys, electronic appliances, mechanical parts, etc. 4. In addition to building sealants, it also includes sealing materials for aerospace, nuclear power plants, electronics, machinery, automobiles and other industries. In the silicone potting material used for electronic components potting, silicone mold glue used as soft mold material, etc. These varieties are in relatively small demand, but they are essential on many occasions. 5. Silicone rubber anti-noise earplugs: comfortable to wear, can well block noise and protect the eardrum. Silicone rubber fetal head aspirator: simple operation, safe use, according to the size of the fetal head changes, the fetal scalp will not be sucked up when attracting, can prevent scalp hematoma and intracranial injury and other ills, can greatly reduce the pain of dystocia pregnant women childbirth. 6, can be used for baby supplies, maternal and child supplies, baby bottles, bottle protective cover. 7.

In contrast, due to the backwardness of technology, domestic rubber sealing ring products can only try their best to get a piece of the pie in the low-end shopping malls. Not only that, but the faltering national companies have to survive. On the one hand, foreign companies aggressively attacked domestic shopping malls, and the suppression of national companies was very severe; on the other hand, foreign companies took advantage of the advantages of mainframe joint ventures to set up barriers to resist the entry of national companies' products and hinder the development of China's national industry. Distance is not only so, the efficiency of foreign companies is dozens of times the domestic. The internationally renowned company Parker-Hanifen, which produces rubber and plastic seals, employs only 90 people, but its annual sales volume is as high as $10 million. However, most of China's 1,000-person companies still lack 100 million yuan in annual sales. From the planning point of view, Froidenbeck is a clan company with a history of 150 years ago, with 82 production factories and 93 sales companies in the world. The group has 28479 employees, with an output value of 4 billion euros in 2004 and seals of 1 billion euros. From a technical point of view, foreign countries are producing new oil seals equipped with sensors to check seal leakage. Moreover, pneumatic seals with main shafts integrated with the benefits of conflicting seals and labyrinth seals have also been produced. Together, U-shaped rubber parts, V-shaped springs, can be used for hydraulic systems with a pressure of 45MPa, pan plug seals and other types of combined seals are popular. These high-precision seal products simply occupy the large wall of high-end shopping malls. We all know that the high-speed development of China's car industry has created a shopping mall with boundless high-performance rubber seals. Car, construction machinery, imported equipment and other repair shopping malls also have the same boundless potential. However, Shuangfeng Shopping Mall did not hold up the golden sun, and the national industry facing double-sided suppression and gap survival could not follow the peak. This appearance was often seen on some construction sites. Some construction machinery often suffered from defecation and urination due to unqualified machine sealing. On the streets, many motor vehicles are also covered with dirty oil. Compared with similar foreign products, this kind of operation often makes people feel guilty. www.mingzhen2006.com
