What are the edge removal techniques for silicone products?

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

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.

Silicone products production process is how it

Silicone products production process is how it

2020-09-09 16:22:45

The production of silicone products is a complex process, the production of each kind of solid silicone rubber products must be the first rubber, and then the production, rubber is the first step in the production process of silicone, then, for rubber, how much do you know. 1. Whether the mixing process is carried out in accordance with the operation process. Although rubber refining is the first pre-process for the production of silicone rubber products, whether the mixing process is carried out in accordance with the operation process is directly related to the quality of the products. If it is not carried out in accordance with the regulations, it is possible that the products produced are accompanied by impurities or the products produced are unstable. 2. The harm of rubber refining jerry-building, if it is rubber refining jerry-building, then the molding of silicone rubber products will also have a lot of problems, such as uneven hard and soft products, more impurities, serious shortage of materials and so on. 3. Control of the former process. Some silicone rubber product manufacturers will not consider that the former process will affect the latter process. In fact, each process is inextricably linked. It is only said that the influence of the latter process on the former process is limited. However, whether the former process is well controlled or not is a problem that a manufacturer must pay attention to. The special silicone rubber product factory is the production of silicone rubber products. I believe that many silicone products manufacturers will encounter the situation of unfamiliar silicone products, silicone products will lead to the appearance and quality can not meet the requirements, and will waste raw materials, then, you know why the silicone products will appear unfamiliar. Generally divided into two types: one is the problem of the external molding period of silicone products, and the other is the problem of the internal molding period of silicone products. External molding period: the appearance and function of silicone products can meet the quality requirements after molding. However, a small part of rubber products will have completely unvulcanized raw rubber, and raw rubber will appear on the surface of silicone products. The internal unripe mainly appears on products with larger volume, which is caused by adjusting the temperature, exhaust and discharge methods during molding. Make the vulcanized product out of the mold in advance. Internal molding period: there is no abnormality on the surface, but in fact there is no vulcanization molding inside. all the faces of the whole product are soft after being molded, and the shape will not recover when pinching the surface with fingers. this product will show sticky objects. when the product is pulled by hand, the tensile strength and toughness strength are stronger than those of good products. 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 manufacturer, to provide you with the best products, silicone products factory in dongguan city

Production process of multi-color molded silicone rubber products

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?
