Silicone seal ring hardness is high, whether the product production is difficult?
 
The demand for various products in the silicone industry is very common in the silicone industry, and the solid oil pressure process accounts for more than 50% in the silicone industry. The largest demand is also the solid molding process, which can achieve materials with different hardness, while the hardness proofing also affects the normal use of products. Some silicone often need high hardness products only in daily life, the silicone seal ring for high hardness will be some problems of the product phenomenon has become a topic of concern to us.
 
High hardness in the silicone products manufacturers industry is indeed there are certain technical requirements, first of all to see whether the development of the mold structure of the product vulcanization has a certain impact, followed by the mold of the exhaust groove really pulled up?
 
Some customers often want about 60 degrees, but they can't tell the hardness of the hardness and can only guess, which leads to the normal use function affected by the hardness of 70 and 80. However, some friends want 90 degrees of material, but verbally say that only 70 degrees and 80 degrees are enough. As a result, the hardness of silica gel cannot meet the requirements after the mold is opened, therefore, it is important to understand the hardness and softness of the product. The reason why the hardness and softness of silica gel is divided into ± 5 degrees instead of ± 1 is also for its reason.

For high hardnessSilicone sealing ringIn the production process, it is necessary to shorten the time and reduce the temperature. Try to reduce its processing hardness and retain its essential hardness. If the vulcanization time is too long, your sealing ring must be very brittle and easy to tear. Pay more attention when using it. If your temperature is too high, the probability of corner tearing of the product will increase, and the aging rate will gradually increase!
 
Therefore, high-hardness products still need certain processing skills in the processing process, saying that it has certain difficulties. In fact, the most important thing is the self-dismantling of the mold and the exhaust groove. As long as the exhaust effect of the product can be obtained, there is basically no problem after adjustment on the machine.
 
In life, many products have a little problem but it is very headache, such as many sealing products and so on. In many cases, the sealing rings and silicone fittings used in life are aging and failing, and their service life is affected. For common joint seals and pipeline sealing rings and so on, a small sealing fitting is broken but affects the overall use. Therefore, it is more important for silicone sealing rings to purchase, otherwise, it will seriously affect the whole product.
 
ForSilicone sealing productsIt can be seen everywhere in life, such as water pipes, drinking fountains, switch valves, etc. Therefore, its adhesion and tightness are still very important. When it comes to quality problems, aging and service life mainly affect it seriously. Therefore, in addition to the use of various environments, the selection of material standards is also very important. Of course, it is also important in the production and processing of silicone product manufacturers, A more qualified silicone sealing ring can mainly distinguish its quality problems from the following points!
 
First of all, whether the raw materials are qualified, and secondly, whether the vulcanizing agent added to the rubber mixture raw materials is qualified, and the main reason why the silicone products are affected by aging is caused by the raw materials, such as light, heat, oxygen, liquid and so on. Secondly, the reason for the size deviation of the vulcanization process! If the sealing is not tight enough, you can find the reason from the product size and the tolerance range of the mold size. The pressure bearing degree is too small, and the long-term active movement sealing products can be found from the vulcanization temperature and time, and the hardness and softness effect of the product can only be achieved under the normal time and temperature.
 
After summing up, in addition to the normal use of the product, in addition to the impact of the environment and the quality of the product itself, we can find the problem from different reasons, in which the main reason for aging symptoms is production and processing and excessive fatigue caused by use.

What is the difference between silicone plug and rubber plug

Silicone plug and rubber plug which one effect is good? Then today we will popularize their difference to where the end point is. First of all, rubber plug products, as a common type of industrial products and accessories, or have strong advantages, such as dust and water resistance, wear resistance, tear resistance, aging resistance, oil seal resistance and ozone radiation resistance, etc., while rubber materials are divided into various types, and the side materials over there can be made of dozens of compound materials, so different attribute functions can be deployed for different needs, as for some industries such as mechanical tight closure, electronic tight closure, vehicle construction and even aerospace and military industry, rubber blocking is the most suitable. Silicone rubber plug and rubber plug have one thing in common. They can be molded in the molding vulcanizer of silicone product manufacturers. The difference is that they are more environmentally friendly, have good high and low temperature resistance, feel better when touching by color hands, and can be in contact with human body skin for a long time. Therefore, silicone plugs for earphones and medical grade silicone plugs are widely used even in food silicone appliances, mainly or because of the material in particular the nature of the achievements of its scope of application. Silicone plug is different. Its material is mainly based on environmental protection advantages, material texture and comfortable application. Therefore, it is used in some electronic products, survival products and small-scale waterproof and dustproof household appliances. Its raw materials are mixed by precipitation method silica gel, high-fine molecular silicone gum and white carbon black. The molecular chain of the product is called heart, soft and comfortable to use! Compared with the materials of silica gel and rubber, they can be compared as follows: new technologies are used in traditional industries. Rubber materials have been heard for a long time in early years, so the comparison of rubber materials accounts for the majority. Up to now, more and more silicone rubber products have been reused because they can replace larger usage compared with rubber, namely environmental protection performance and various technologies, such as shape, pattern and color, etc. www.mingzhen2006.com

What are the fields of application of silicone keys for equipment

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

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. www.mingzhen2006.com

What are the molding techniques of rubber products?

Calendering: suitable for the manufacture of simple sheet, plate products. It is a method of pressing the mixture into a film through a calender called calendering. Some rubber products (such as tires, tape, hose, etc.) used in textile fiber materials, coated with a thin layer of glue, glue coating process is generally completed on the calender. The fiber material needs to be dried and dipped before calendering. The purpose of drying is to reduce the moisture content of the fiber material (so as to avoid water evaporation and foaming) and increase the temperature of the fiber material to ensure the quality of the calendering process. Dipper is the process before hanging glue, the purpose is to improve the binding performance of fiber materials and glue. Extrusion molding: Used for more complex rubber products, such as tire treads, rubber tubes, and metal wire surface coatings, which need to be manufactured by extrusion molding. The plastic mixture was placed into the hopper of the extruder. Under the extrusion of the screw, a method of continuous molding through a variety of mouth before pressing out, the rubber material is preheated to make the rubber material soft and easy to extrude, so as to obtain rubber products with smooth surface and accurate size. The rubber industry is one of the important basic industries of the national economy. It not only provides people with light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts for heavy and emerging industries (such as mining, transportation, construction, machinery and electronic products). It can be seen that there are many kinds of products in the rubber industry, and the backward industry is very extensive. Molding molding: can also be used to manufacture some complex shapes (such as cups, seals) of rubber products, with the help of the molding of the female and male molds, the rubber material is placed in the mold and heated. www.mingzhen2006.com

How to print the pattern on the transparent key

Some laser marking machines have played opaque keys. While using laser typing to knock out the paint, they will also burn the plastic parts that can transmit light, but cannot transmit light! Changzhou laser marking machine has a special device, which can adjust the machine to the function of laser processing light-transmitting key. The laser can clean the paint sprayed on the surface very clean without burning light-transmitting plastic, thus realizing light-transmitting key laser processing! YAG laser marking machine, the general laser marking machine can not do through the key! Light transmission keys, also called light transmission buttons, are widely used in electronic products. In dark environments, they can accurately and accurately find each button. The light transmission keys include a light transmission key body, an electronic switch located below the key body, and a luminous body. The luminous body is arranged on the lower side of the key body. A light guide body is arranged below the key body, and the light guide body has a body, the upper side of the body extends an extension to the position where the electronic switch is located, the outer surface of the extension is a first reflective slope, the lower surface of the body is a second reflective slope and doubles as a light touch surface that can be contacted with the electronic switch, and a light input part connected with the extension part and arranged corresponding to the light emitting body, the light emitting body emits light, the light is emitted to the first reflective slope through the introduction portion, and is reflected by the first reflective slope into the body, and the light entering the body is reflected by the second reflective slope out of the key body. The structure makes the light emitted from the light emitting surface of the key body more uniform, the key is more beautiful, and the user can accurately find the corresponding function key.
