What are the edge removal techniques for silicone products?

2020-09-11 11:31:28

The edge removal process is an essential process after silicone molding. If the edge removal is careless, the burrs remaining on the silicone products will greatly affect the appearance of silicone products. Do you know how many methods there are for the self-removal of silicone products. 1. Manual self-disassembly: This is the most commonly used method. The advantage is low cost. The operator only needs to hold a tool and gradually repair the overflow along the outer edge of the silicone product. However, the disadvantage is that the efficiency is low and the quality is difficult to guarantee. Especially for products with complex configuration and high precision requirements, it is difficult to be thorough and clean, moreover, it is easy to damage the connection between the body of the silicone product made of silicone and the overflow edge, often leaving tooth marks and gaps, thus leaving behind problems such as oil leakage and air leakage that affect the sealing. In addition, the dependence of manual trimming on the proficiency of operation is also very prominent. Second, the machine edge removal: the advantage is that it can improve the efficiency and quality. The machine usually uses a special electric edging machine with a rotating blade. The blade used must be highly matched with the size of the product. If the inner and outer edges of the product have overflows, it can be designed as double-edged and multi-edged. Third, cold side dismantling: the improvement of working efficiency and processing quality and machine trimming have their own advantages. The vulcanized finished product is connected with the waste side of the silicone product factory, and the edge is removed under freezing conditions. The process is to cool the vulcanized product under freezing and dynamic conditions, so that the waste side enters a brittle state, and then through mutual friction between themselves, or in rotation and vibration, under dynamic conditions such as swing, the waste edge is removed by friction, or the rigid pill-like medium is made. How to judge the temperature of rubber O-rings, rubber seals, rubber seals and other rubber sealing products. If the pressure is unchanged, the higher the temperature, the shorter the vulcanization time will be. On the contrary, the lower the temperature, the longer the vulcanization time will be. Rubber high molecular polymers and rubber products will destroy the molecular chain under high temperature conditions, resulting in the fracture of cross-linking bonds, I .e. presentation, vulcanization returning to the original, scene, and vulcanization temperature judgment, because the equipment and abrasive tools are existing in the enterprise, the pressure and time will be judged accordingly. Individual sulfur vulcanization system vulcanization temperature selection category 130~158 ℃, effective, semi-effective vulcanization system vulcanization temperature selection category 160~165 ℃, resin or peroxide vulcanization system temperature between 170~180 ℃ is appropriate, silica gel products have an open porous structure, can absorb many substances, is a good desiccant, adsorbent and catalyst carrier. silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom tel: 0769-86652688-808,https://www.mingzhen2006.com

Why transparent silicone products yellowing process how

2020-09-09 16:47:49

I don't know if you have such doubts. Some newly released transparent silicone products look yellow, as if they are not transparent and have colors. The finished transparent silicone products will not turn yellow after being normally placed for several years. What are the reasons for such differences. 1, vulcanizing agent: ordinary type does not resist yellow vulcanizing agent, applied to some can be used for color is relatively deep or the color request is not high non-revealing silicone products. Anti-yellowing vulcanizing agent used in demand revealed, silicone products with lighter colors and higher color requirements.. 2. Technical aspects: When the transparent silicone product is molded, the color of the transparent silicone product turns yellow after molding. The main questions are: the mold temperature is too high and the vulcanization time is too long. 3. The quality of the material itself is too poor: add anti-yellowing vulcanizing agent to the glue, but the transparent silica gel product still looks yellow after molding, which may be because the anti-yellowing ability of the material is too poor. The material proposition that the anti-yellowing property of the material is too poor for the silica gel product factory is direct material replacement. With the rapid development of modern industry, especially the chemical industry, there are many kinds of rubber products, but the production process is basically the same. The production process of products with general solid rubber (raw rubber) as raw material mainly includes:. 1. Mixing in an open mill: raw rubber (roll wrapping)-→ vulcanizing agent-→ colorant, etc.-→ thin remelting-→ sheet extraction. When silicone rubber is added to the rubber mill, the slow roll (front roll) is wrapped, and when rubber products are mixed, the fast roll (rear roll) is wrapped quickly. 2. Molding: First cut the rubber material into a certain shape, weigh it, fill it into the mold cavity, close the mold, place it between the upper and lower plates of the heated flat vulcanizer, and heat and pressurize it according to the specified process to vulcanize the rubber material, and unload the mold to obtain a section of vulcanized silicone rubber product. The quality of the molded product is closely related to the design and manufacturing process conditions of the mold. Related. 3. Trimming processing: according to different products to choose different fixture trimming. Dongguan Mingzhen Rubber and Plastic Products Co., Ltd. has more than 200 production factories, a sales professional team and 12 years of processing experience in the silicone rubber industry. Mingzhen has 20 silicone rubber full-automatic and vacuum oil presses, automatic production lines such as silk screen spraying, etc. It produces all kinds of silicone keys, rubber keys, silicone rubber products, electronic cigarette silicone accessories, silicone rubber protective covers and other silicone rubber products, silicone miscellaneous sealing rings, keys, 12 years of silicone rubber professional custom manufacturing manufacturers, to provide you with the best products, silicone products factory in dongguan city custom phone: 0769-86652688-808,https://www.dgminz.com/.

Experience in the production of high quality silicone seals

2020-09-04 11:09:44

The most important thing about silicone rubber products manufacturers customizing several rubber sealing rings is the problem of commodity molds. The customized production and processing of miniature silicone sealing rings have higher standards for self-trimming, because most of the miniature commodities with smaller specifications are all made of mechanical equipment to intelligently remove burrs from the trimming, and only manual simple cutting and repairing are required in human technology. Therefore, the quality precision of the mold and the selection standard of mold materials are relatively high, at the same time, the layout design and structure of the mold of the commodity is also very critical. The mold with clear sideline and clear feeding groove will certainly have corresponding assistance in the processing technology! As we all know, there is a difficult whole process from the development to the production and manufacture of several customized products. Silicone rubber products must be continuously tested from the specification and size installation of the developed products to the selection of raw materials for characteristic inspection. However, there are similar conditions in the whole process of silicone ring processing technology. An inconvenient process is likely to cause different problems in the processing of several products, what can't cross the past for silicone sealing rings? The key to the selection of raw materials, in many cases, the problem of commodity raw materials cannot be accurately predicted, because the silicone rubber sealing ring should be empty in the inner part of the hollow circle, while in the whole production process of silicone sealing ring manufacturers, the raw materials must be put into the positioning point for vulcanization, so the net weight of burrs is of course more than that of other commodities, so in many cases the cost budget does not match the net weight of the price deviation of commodities, the production cost deviation of the commodity. If the strength of the goods is not selected correctly, the actual sealing effect cannot be achieved. It is also extremely worrying for dealers and suppliers. Therefore, the routine application is determined by early sample determination! There are many difficult and miscellaneous diseases for silicone rubber O-rings, and the application fields of commodities are very wide. In addition to the above problems, the abnormal causes of commodities and their working efficiency should be fully considered in the processing process. At the same time, whether the commodities can achieve practical application results in terms of sealing performance and other components should be considered. The key significance of customized production and processing of silicone rubber is based on the requirements of customers, therefore, you have to look at the application of your products in that industry and natural environment!

Production process of multi-color molded silicone rubber products

2020-09-04 10:52:44

The key to the relatively simple two-color and three-color silicone rubber products is to choose the second shaping production and processing method. The key to this method is that the secondary color body is dry and fixed first when the silicone rubber product processing factory manufactures, and the color sub-device is poured into the main color mold cavity to stabilize, and the second vulcanization is carried out when the main color plastic material is poured. The goods made are not much different from the glue dripping production process, however, this kind of method also depends on the structure and size of the commodity in color tone. If the commodity is too small and the color K is not well arranged, the complexity of color tone manipulation will interfere with the actual effect. Therefore, this kind of production process is not very difficult to make many colors simple. The production and processing of structural internal packaging printing is a very popular production process nowadays. It is mainly similar to the thermal transfer process. The products are integrated and shaped in the mold with more texture, and the production and processing are not separated independently. This kind of method is also made according to the pressure molding of silicone product manufacturers. The key is to pour the cardboard of the packaging printing pattern printer into the mold to carry out the molding. After the successful preparation, the actual effect is the same as that of the thermal transfer process, it should be the actual effect of transfer printing, and this type of silicone products can be done on more than ten tones. At present, many silicone rubber jewelry categories are selected in this way! In order to realize the customer experience of many customers in the field of silicone rubber, multi-tone products should always be very popular products. However, in view of the control of production process and cost, many manufacturers of silicone rubber products will also choose some cost-reducing and simple production and processing methods when manufacturing two-color and multi-color products. Everyone knows that molding production process is the most common type in the field of silicone rubber products, for this type of silicone products with very few tones, it is also possible to completely achieve multi-color practical effects. What is the way to use it to make multi-tone products?
