What is the difference between the laser carving process of silicone keys

What is the difference between the laser carving process of silicone keys

2021-03-11 17:13:31

Laser engraving of silicone keys is abbreviated as laser engraving, which is also called laser marking in the industry. It is a kind of surface treatment process of silicone keys. Its appearance effect is similar to that of silk screen printing of silicone keys. Words and various symbol patterns are printed on the surface of silicone keys. Laser carving is the use of optical principle in the surface of the silicone key processing, so that the silicone key surface to form the need for text and symbol patterns, is mainly used in mobile phones, electronic dictionary keyboard and remote control buttons. Under the condition of sufficient light source, the appearance of silicone keys using laser carving process is very similar to that of silk screen keys, and it is difficult to distinguish between the two if not professionals. If you touch the characters of the laser keys with your hand, you will feel concave, while the characters of the silk screen keys will feel convex. However, the concave-convex feeling is very slight and needs careful experience. The purpose of laser engraving is to use laser to burn the color oil sprayed on the surface of silicone keys to produce the required characters and patterns. Therefore, silicone keys that need laser engraving usually need oil injection. For example, a silicone key has a black surface and red characters. According to this appearance requirement, we can realize the silk screen printing method of printing black characters first and then red characters. However, if the red characters are required to transmit light, then the silk screen printing process cannot be realized, because the black background cannot transmit light, and then we need to use laser engraving. No corrosion to metal, temperature resistance, high temperature resistance, good aging resistance. After curing, the rubber elasticity is maintained in a wide temperature range, and the insulation performance is excellent.

What is the difference between silicone rubber products and screen printing

What is the difference between silicone rubber products and screen printing

Seal ring mold printing is much simpler than silk screen printing. The mold printing does not need the second process to complete, and is directly formed with the product at one time. The mold printing can only make some relatively simple patterns, such as logo and other patterns can be made through molds and directly formed. Silk screen printing and mold printing are also different in processing into liquid silica gel books. Relatively speaking, the cost of silk screen printing is much higher. Considering the cost, the choice of the two can be made according to the complexity of the graph. In the molding process of solid silicone rubber products, many people do not know how the raw materials are cured by high-temperature molding. Raw materials, temperature and mixing are essential processes, and there is also an auxiliary agent that is one of the main auxiliary materials. Vulcanized crosslinking agent, if only the raw materials are put into the mold and enter the silicone key manufacturer for high-temperature curing and molding, the product cannot reach the curing effect, so have you understood the function of vulcanizing agent. Vulcanizing agent can be used in different kinds of rubber. At present, rubber vulcanization is the same as silica gel vulcanization. Its main function is to put the curing agent into the raw material of the seal, completely mix the curing agent and the raw material evenly and completely mix the raw material to achieve the curing effect. After curing at high temperature and strong pressure of the machine, the silicone molecules are cured at high temperature and transformed into high density compatible products. This kind of industrial rubber product is the earliest suitable for natural rubber materials, at present, the rise of silicone products manufacturing industry. At present, the color of vulcanizing agent is transparent, and at present it can still reach the level of environmental protection and safety. The main defect of compatibility with silica gel lies in the odor of rubber key curing agent manufactured by some enterprises or the yellowing of silica gel products. The stability of catalytic effect is the key to it. Many silica gel processing plants also have various undesirable conditions of products due to curing agent, so the stability of curing agent is very important. Screen printing is a post-process after the product is formed. Screen printing is mainly used, which is different from mimeograph and color printing. The main tools are screen printing and oil brush. Screen printing is a pattern made of an iron frame or a wooden frame, and this pattern is a pattern printed on the product by silk silicone products. When screen printing products, align the screen plate with the plane where the products need to be printed, and coat the screen plate with ink. The ink will leak from the gap of the screen plate pattern to form the corresponding pattern on the products, and then put it into the silicone key of the baking oven to dry. The temperature should not be too high. According to different products, the baking time and temperature are generally different, compared with mold printing, silk screen printing can do slightly complex patterns, can also be multi-color printing.

Why do silicone products bond dark marks

Why do silicone products bond dark marks

Silicone products appear dark mark how to do. Silicone products have the characteristics of colorless, tasteless and boundless. To change the silicone products of silicone key manufacturers into colorful colors, it is necessary to add "color masterbatch". Therefore, there must be no mistake in the selection of color masterbatch. If the temperature resistance of color masterbatch is not good, then basically silicone products become waste products. Seals are molded at high temperature because color masterbatch is integrated into silicone products, at this time, the color masterbatch is melted at high temperature to change the color of silica gel products. If the color masterbatch affects the whole production because of its poor temperature resistance, the consequence is self-evident. The rubber products must choose the most appropriate one in terms of the choice of color masterbatch. When selecting silica gel raw materials, strict control must be carried out on them. For silica gel raw materials, such as two different silica gel raw materials, it may be difficult to distinguish the difference between color rubber keys and hardness on the naked eye, but in fact there are still differences between the two. If the two batches of silica gel raw materials are mixed and molded, the quality inspection after molding finds a small color difference, and they cannot be shipped, our quality inspection is very strict. With the continuous development of technology in the silicone industry, the application is also more and more widely, but sometimes in the application will encounter some problems, such as how the glue can be bonded with other miscellaneous parts, this is a very important problem, silicone products It is worth us to understand and use. 1, silicone rubber) sealing strip manufacturer introduced white oil or toluene to clean up the area where silicone rubber miscellaneous parts need to be pasted with double-sided adhesive. Oil stains, dirt and water stains are added with diluent in proportion and stirred evenly for later use. Note: silicone rubber key adhesive and rubber have different material properties. Silicone rubber treatment agent is used for silicone miscellaneous parts and rubber treatment agent is used for rubber keys. The two cannot be mixed and used wrongly, otherwise it will lead to degumming after pasting. 2. Adhesion of silicone products: The treating agent is evenly applied to the area where adhesive needs to be applied to the silicone rubber miscellaneous parts of the sealing ring. After evenly applied, the silicone rubber miscellaneous parts are placed in a cool and ventilated place until the treating agent is naturally air-dried. After the treating machine on the silicone rubber miscellaneous parts is naturally air-dried, the double-sided adhesive is applied to the area where double-liquid silicone rubber surface adhesive needs to be applied. The silicone rubber miscellaneous parts have been tightly bonded, high and low temperature resistance, good aging resistance, high temperature resistance, in line with FDA and SGS standards. 3. After gluing, the silicone product factory can be compacted mechanically or by pressing. The film should not be too thick. The method of pasting thin film layer by layer to the required thickness is adopted.

To meet your needs, accessories and other products can be customized according to their own appearance design and functional requirements, such as the functional hardness and sealing performance of liquid silicone products, the appearance decoration effect of the products, etc. After the accessories are assembled, if they cannot meet the use requirements, they can be remodeled according to their own ideas and designs. If the products are glued, the silicone products factory can repair the products, if the product is reduced, it will be even more troublesome, so pay attention to the material and process when designing the drawings. The oil spraying process of silicone products must be well known to everyone. At present, it may be used in many silicone daily necessities and sub-products of electric silicone key manufacturers. Its processing technology is mainly to improve the quality and use methods of silicone products. In silicone product molding manufacturers, this type of process is mostly used. However, the presentation of silicone oil spraying process is mainly the change of consumers and product values of seals, any customer wants high-quality beautiful and comfortable products, so the fuel injection processing is responsible for providing beautiful and comfortable. Speaking of oil injection processing, spraying and oil injection processing are currently an indispensable type of rubber products in different industries. For example, our silicone products, plastic products and other rubber and plastic products may be used in appearance parts, and spraying is more widely used in hardware and textile industries. Rubber keys have become an indispensable type of processing technology in our life. However, with the environmental protection supervision in recent years, the spraying industry has been inspected and rectified by gravity, which has led to the gradual rupture of many small and medium-sized enterprises in this industry, and they have not made good progress in technology and experience. Silicone rubber gaskets are divided into different functions, such as foot pads, dining table pads, sealing pads and other different shapes and structures. Different processing methods have different processes. Although the materials are the same and the products produced have different functions, large-scale products need large-scale raw silicone products to produce oil pressure equipment for processing customization, and this process selects silicone molding process to account for the majority. The ice cube has various shapes, rich colors, and is non-toxic and tasteless. You can choose the most classic silicone ice cube, make ice cubes, and add silicone keys to cola to get a refreshing drink than fast food restaurants. You can also choose creative shapes such as fruit shape and animal shape, which are crystal clear and very beautiful in the cup. Summer fast food, such as iced cold noodles, cold dishes, etc., is crispy and refreshing with ice sealing ring blocks. The silicone ice tray is also equipped with corresponding silicone covers. The ice cubes are placed in the refrigerator to prevent smell and are considerate and convenient.
