With the advancement of science and technology, the development of the automobile industry, especially the continuous emergence of new materials, Dongguan Silicone Products Factory people have higher and higher requirements for automobiles, and the requirements for automotive silicone seals are constantly being updated. The rationality of the structure, the humanization of the design, the process and automation of the production process, the safety, environmental protection, recyclability, supporting aesthetics and diversity of the products are all the product performance that automobile silicone seal enterprises need to consider.
 
In recent years, China's automotive silicone sealing industry has achieved leapfrog growth. Future development will be unstoppable. At present, the domestic automotive silicone sealing industry has 20 key production enterprises, including 6 joint ventures, accounting for 33. 3%. These enterprises are widely distributed around the automobile main engine plants to maintain a reasonable and economical supporting radius. However, due to the large number and small scale of China's automotive silicone seal industry, it is difficult to form a scale climate, which is far from the market competitiveness of foreign enterprises.
 
However, when increasing production capacity, we must not only solve the immediate urgent needs, but should combine factors such as improving labor productivity, quality improvement, product structure upgrading, and technological progress to comprehensively increase the comprehensive production capacity of enterprises.
 
Silicone produces 500000 sets of automotive silicone accessories annually, and its operating income has maintained a compound growth of more than 30% for 3 consecutive years. In addition to the current car antenna silicone gasket in the Japanese car antenna market share of 80%, the company's other silicone products, such as silicone wire harness tube, car waterproof seal, silicone sealing strip, industrial silicone products, engineering silicone seals, silicone coating products, etc., are also widely used in major brands of cars.
 
With the booming of China's automobile market, it provides huge space for the development of the automobile interior industry. It is understood that the single automobile supplies market is calculated by hundreds of billions, such as car navigation, PVC floor cushion leather, ABS board and its composite board, etc. will benefit from it. Low-carbon environmental protection has become a life philosophy of contemporary people. New materials are widely used in automotive interiors due to their energy-saving, environmentally friendly, fashionable and beautiful characteristics. In this context, how to develop environmentally friendly and wear-resistant interior materials is what companies should seriously consider.
 
PVC is quite popular in the world today and is also widely used as a synthetic material, the main component of polyvinyl chloride, in addition to the addition of other components to enhance its heat resistance, toughness, ductility and so on. However, PVC does not have the function of softness and anti-skid and cushioning before foaming. Only after foaming can it produce finished products such as yoga mats and automobile anti-skid mats. In addition, PVC in the use of leather products such as car cushions, mainly through a special coating process made of PVC artificial leather, from the appearance of texture is an ideal substitute for natural leather, in terms of waterproof, mildew and other aspects is more than natural leather.
 
PVC foam board die-to meet the special requirements of the product The quality of PVC foam board products mainly depends on the PVC foam process formula, equipment, and die structure design. Jingcheng series foam board die head is suitable for PE, PP, EVA and other raw materials to produce foam products through special flow channel design;
The special die lip temperature control device ensures compliance with the requirements for the production of products with different foaming ratios; it can be used in conjunction with a co-extrusion distributor to produce a series of co-extrusion foaming products, with the surface skin layer not foaming and the core layer foaming. PVC foam board die through special steel design, surface treatment and international advanced electroplating process, with its wide diameter, hanger-type runner design, unique mainstream rod manufacturing process, to overcome the PVC material corrosive processing difficulties.
 
The micro-layer co-extrusion composite die head technology consists of a micro-layer distributor, a composite multiplier, a cladding distributor and a manifold die head, which realizes the micro-layer co-extrusion of more than 50-1000 layers in the range of 0.01-0.1mm, effectively reducing the fracture and crack problems of the product.
 
Battery isolation film technology-effectively improve the energy storage of batteries In today's increasingly fierce global energy crisis, luxury cars that have never cared about fuel consumption before, and even some top luxury car brands, have also joined the green army of energy saving and emission reduction, and go all out. Innovation and research and development of environmental protection and energy-saving technologies. At present, the development of new energy vehicles in various countries is basically in the initial stage, so whose future is stronger will determine who will win a better future. At present, my country has made phased progress in the development of new energy-saving technologies and energy-saving products.
 
Looking at the technical requirements of new energy vehicles, the key lies in the storage of energy. If the "super capacitor" can be found, the problem can be solved. The so-called super capacitor is a new type of energy storage device, which has the advantages of high power density, large capacity, long service life, maintenance-free, economic and environmental protection. The development of upstream and downstream industries of supercapacitors will greatly enhance the market competitiveness of China's automobile energy-saving industry. Battery isolation film technology is one of the key technologies for the development of new energy vehicles. The use of new materials for packaging can not only play a good bonding and sealing effect, but also help improve the energy conversion efficiency of the battery and effectively improve the energy storage capacity of the battery., Further from the "super capacitor.

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
