Is it difficult to produce silicone sealing ring?
 
High resistance silicone seal ringManufacturer which is good, silicone sealing ring production should pay attention to what:
 
As we all know, it is a difficult process to customize a product from research and development to production. Silicone products are no exception. Continuous testing is required from the size assembly of the research and development product to the selection of performance testing materials. Similar phenomena also occur in the production process of high temperature resistant silicone sealing ring. A troublesome process may cause different problems in the processing of a product, so for high temperature resistant silicone sealing ring and what is difficult to cross the past?
 
About silicone products manufacturers to customize a silicone sealing ring is the most important product mold problem, smallHigh temperature resistant silicone sealing ringCustomized processing has higher requirements for self-dismantling lines. Since most small products with smaller sizes use mechanical trimming to automatically remove the burrs of self-dismantling lines, and only manual and simple trimming is required in manual processes, the working accuracy of the mold and the selection requirements of mold steel are relatively high. In addition, the mold layout structure of the product is also very important, with clear lines, the mold with clear discharge groove will naturally help in the production process!
 
The importance of raw material selection, many times the product material problem can not be accurately predicted, because the silicone rubber ring belongs to the empty circular middle part, but in the silicone sealing ring manufacturer production process, but need to put the material into the center point vulcanization, so the weight of burrs is naturally more than the weight of other products, so many times the budget is not allowed to product weight will appear price error, product cost error phenomenon.
 
The hardness of the product is not selected correctly, which leads to the failure of the sealing effect. This is what the supplier is most worried about and what the supplier is most worried about, so make samples in advance to confirm normal use!
 
For silicone O-rings, there are many difficult and complicated diseases, and the products are widely used. In addition to the above problems, the adverse factors and production efficiency of the products should also be considered in the production process. On the other hand, whether the products can achieve the use effect when assembled and sealed on other substances should be considered. The main purpose of silicone customized processing is according to the needs of customers, so it depends on the field and environment in which your products are used!
 
The characteristics and application of silicone sealing ring: silicone sealing ring is a kind of sealing ring, which is made of various silica gel as raw materials for fixing the ring cover, so that it can match the gap between the ring or gasket on the bearing, A tool to prevent various moisture or oil leakage. At present, it is mainly used for waterproof sealing and preservation of daily necessities such as fresh-keeping boxes, electric rice cookers, water dispensers, lunch boxes, heat preservation boxes, fresh-keeping boxes, water cups, ovens, magnetized cups, coffee pots, etc. It is easy to use, safe and environmentally friendly, and is deeply loved by everyone.
 
So today, let's take a look at the silicone seal ring. Silica gel, is a highly active adsorption material, is an amorphous material, is a rubber material, its chemical formula is mSiO2 · nH2O. And insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, in addition to strong alkali, hydrofluoric acid does not react with any substance.
 
Because of its special performance, wide temperature range and excellent chemical properties, it is a special rubber together with fluorine rubber. Therefore, silica gel is also widely used in the production of various seals to meet various sealing requirements in our mechanical production and life. So what are the advantages of silicone sealing rings compared with other materials?
 
Wide range of 1. temperature resistance 1. Heat resistance: It has much better heat resistance than ordinary silica gel. It can be heated at high temperature without deformation or harmful substances. It can be used almost forever at 150°C without performance change, can be used continuously for 10000 hours at 200°C, and can be used for a period of time at 350°C. Widely used in heat-resistant occasions, such as: hot water bottle silicone sealing ring. 2, cold resistance: ordinary silica gel late for -20 ℃ ~-30 ℃, and silica gel at -60 ℃ ~-70 ℃ still has good elasticity, some special formula of silica gel can also withstand very low temperature, such as: low temperature silicone sealing ring, the lowest can reach -100 ℃.
 
Silica gel with good 2. insulation performance has excellent electrical insulation performance, corona resistance (the nature of resisting quality degradation) and arc resistance (the ability to resist deterioration caused by high-voltage arc) are also very good.
3. moisture absorption performance of silicone ring surface energy is low, the moisture in the environment has the function of absorption and play a role in isolation.
Excellent weather resistance of 4. weather resistance refers to a series of aging phenomena such as fading, discoloration, cracking, pulverization and strength decline due to the influence of external conditions such as direct sunlight, temperature changes, wind and rain, etc. Ultraviolet radiation is the main factor to promote the aging of products. The Si-O-Si bonds in silica gel are very stable to oxygen, ozone and ultraviolet rays, and have excellent resistance to the erosion of ozone and oxides. In the case of not adding any additives, it has excellent weather resistance, and even if it is used outdoors for a long time, cracks do not occur. It is generally believed that silicone seals can be used outdoors for more than 20 years.
 
5. material safety and environmental protection silicone has its unique physiological inertia, non-toxic, tasteless, odorless, good preservation effect, and less interference by the external environment, long-term use of yellow, do not fade.
 
6. High permeability and selectivity to gas permeability due to the molecular structure of silica gel, silica gel sealing ring has good permeability and good selectivity to gas. At room temperature, silica gel has 30-50 times higher permeability to air, nitrogen, oxygen, carbon dioxide and other gases than natural rubber.
 
Characteristics and Application of Silicone Sealing Ring
After reading the advantages of silicone sealing ring, we will not be curious about the shortcomings of it? What are the shortcomings of the silicone sealing ring?
 
1. tensile strength and tear strength mechanical properties are poor at room temperature, its physical and mechanical properties are less than most synthetic rubber (except nitrile silicon, fluorosilicone rubber), low tensile strength and poor tear resistance. It is not recommended to use silicone sealing ring for stretching, tearing and strong wear in the working environment. Normally, only static sealing is used.
 
2. water vapor resistance is poor, the pressure exceeds 50psi is not recommended.
 
Although 3. silica gel is compatible with most oils, compounds and solvents, and has good acid and alkali resistance, it has no resistance to alkane hydrogen and aromatic oils. Therefore, it is not suitable for use in environments where the working pressure exceeds 50 pounds. In addition, it is not recommended to use high temperature resistant silicone seals in most concentrated solvents, oils, concentrated acids and diluted caustic solutions.
4. price is more expensive than other silicone products.
 
The above is the relevant introduction of the performance characteristics of the silicone seal ring. The silicone seal ring is made of food-grade silicone material, which has the characteristics of no deformation and no aging under extreme temperature conditions. Because of its superior reliability, longevity, extreme temperature applicability and stability, it has been widely used. It has played a very important role in our daily life and brought us a lot of convenience. I hope that today's introduction can give you a more comprehensive understanding of the silicone seal ring, how to use the silicone seal ring reasonably and correctly in the future life.
 
The general customer will be concerned about the product price, quality, service, production strength, the production of silicone sealing ring manufacturers are numerous, the quality is uneven, how can in this case, choose some good suppliers?
 
First of all, let's talk about some wrong views that we usually look for silicone sealing rings. First of all, we often take the price as the only choice standard, but in fact we are wrong. We need this product. Price is not the only standard that determines the quality, but it will also affect the quality of silicone sealing rings to a great extent. Many manufacturers attract customers at low prices, but the raw materials they use are not good, or the workmanship is poor, in this case, it is useless for us to choose the low price.
 
Secondly, service is very important. Whether the delivery is on time, pre-sales consultation, after-sales attitude towards abnormal products, whether the products are professional, and whether the products can be customized according to customers are all important factors for considering this silicone seal manufacturer.
 
Another is that when choosing a manufacturer, we only look at the price. We also need to look at the professional direction of the manufacturer. There are many silicone product manufacturers, but each silicone manufacturer has its own professional products. Some products are not technically very good, so it is likely to lead to poor quality and delayed delivery.

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
