Silicone protective sleeve style silicone products demoulding machine mobile phone sets have peculiar smell?
 
What do you need to have?Protective Sleeve? There are a variety of different types of electronic protective shell, different materials, but there have been questions about the role of silicone protective cover is where?

In fact, brands such as iphone, Huawei and Samsung have already done enough work on their products to deal with the extreme appearance and surface treatment itself. Therefore, this is also a question that many people often raise. This is why high-end and expensive mobile phones need a silicone mobile phone protective cover. We learned that after the iPhone X and 8 came out, the cool shell food-grade silicone protective cover was officially launched. The first feeling of the solid silicone protective cover launched by Apple's official website was definitely that other materials could not be compared. Of course, the feeling brought by materials could not be achieved by any product. Therefore, it is inevitable that a stall of silicone material will become a hot and sought-after silicone product due to its mature technology!
 
In addition to Apple, almost every brand has its own silicone protective cover, so silicone products are currently a hot commodity! Speaking of here, why do many people need a silicone phone set?
First of all, the material of the product is soft. Generally, you will like this feeling after touching it with your hands. After the treatment of anti-skid hand-felt oil, the surface is clearer and more delicate. In addition, it is special in that it is soft and stretchable and has good cushioning. When falling on the ground, it has the effect of cushioning and decompression. Naturally, it can achieve the function of anti-fall and anti-collision. Compared with hard shell material, it can arbitrarily twists and rebound, durability and practicability is longer.
 
In terms of material, silica gel itself is environmentally friendly and non-toxic, afterSilicone Protective ShellThe manufacturer's high-temperature vulcanization molding at about 200 degrees has already added sulfur once on the machine table and is worried about causing harm to the body. General materials can be divided into food-grade and medical-grade silica gel, high-performance tensile silica gel and other materials, mainly depending on the kind of demand the product tends to choose, so mobile phone users all need a silicone sleeve, mainly attracted by the material properties of silica gel! What is the role of release agent in silicone products? In order to improve the processing efficiency and smooth production in the silica gel products industry, some treatment agents and vulcanizing agents are often used as auxiliary tools to ensure the normal and smooth demoulding of products. The function of mold release agent is just one type. As a basic material, silicone can be divided into many functions, and mold release agent is one of them, and mold release agent can be divided into many types and can be divided into product form, material form and liquid use form!
 
Now the manufacturer of silicone products should be very clear about the release agent, its use method, use effect, etc., and the release agent has anti-chemical styrene, amines and other contact is not dissolved, not easy to be decomposed and worn, he is mainly used in molding, injection molding, extrusion, molding, lamination and other processes, without any chemical damage to the product, it has the ability to form a uniform film and form a complex shaped article with accurate dimensions.
 
Demoulding performance is good, for silicone products manufacturers, spray type release agent table tension in 17 to 23N/m directly, it is mainly heat resistance, pollution resistance, lubricity, demoulding continuity, stability and other characteristics, in the production process to get a good auxiliary role! The basic materials of mold release agent belong to organic organic chlorosilane and organic alkoxysilane, among which it can be divided into methyl ethoxysilane, phenyl chlorosilane, phenyl ethoxysilane and other organic compounds. They are all liquid auxiliary products, which are generally sprayed on molds and substances that are difficult to fall off with high viscosity as references. The main function in the silicone product industry is to directly spray on the surface of the mold so that the silicone raw materials can be rapidly demoulded after molding.
 
The function is to improve the efficiency. As the different structures of the mold and the shape of the product have a certain viscosity when molded at high temperature with silica gel, the product can maintain good demoulding after spraying the demoulding agent, and the phenomenon of sticking to the mold will not occur. During processing, the whole mold of the product can be directly removed, thus improving the processing efficiency, and silicone product manufacturers want to improve product efficiency in addition to demoulding, there will also be different methods to use, such as mold and machine adjustment mobile phone case smell how to do, should be thrown away?
 
Silicone phone caseIt is a kind of electronic decoration product that is relatively popular at present. How can the quality problem of customized silicone mobile phone shell products be normally sold to consumers without any problem? This material is the most important. What are the main factors that cause odor in the production of mobile phone shells by some silicone product manufacturers, and is there any way to solve it?
 
The safety problem of silica gel products mainly lies in the smell and material, so the appearance of the smell of silica gel products is also the main factor that makes people speculate and causes the smell of silica gel products to appear lies in the vulcanizing agent added to the raw materials during production and the catalyst demoulding water, etc. When the flat silica gel vulcanizer is formed, the smell from the mold at high temperature is baked out by high temperature vulcanization and trapped in the product!
 
So this is entirely in the question of raw materials! Imagine that the smell will come out when the machine is ripe when cooking. this silicone protective sleeve has a similar situation after being molded. the smell belongs to normal glue and is not harmful. generally, some smell will naturally appear on consumers' hands after long-term sealing. under normal circumstances, silicone product manufacturers need to carry out secondary vulcanization odor treatment on the products, after the finished product is baked at high temperature, the initial taste can be sealed, bagged and shipped after 24 hours of placement. Therefore, the main reason for the high odor may be due to the fact that there is no secondary vulcanization surface treatment, the direct packing without volatile odor, the strong odor of the product with high processing temperature during vulcanization production, and the addition of essence or toner, etc!

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. The pattern and text on the keys are processed by laser typing! In our life, there are many keys and buttons that use laser typing and can transmit light, such as mobile phone keys, car audio keys, computer keys, and various electronic and electrical keys! www.mingzhen2006.com
