Silicone pads are used in every industry as one of the main accessories for cushioning, shock absorption, and gear protection. Their application has occupied a certain market distribution demand and can be seen everywhere in our daily lives. They are not as good as foot mats, anti slip pads, protective silicone pads, and cushioning and shock absorption pads. Many silicone adhesive pads are fixed by sticking double-sided tape to prevent detachment and sliding after too long. Therefore, under normal use, except for human conditions, 3M adhesive pads are unlikely to easily fall off because certain skills are also required in the backing process and processing. These experience skills can greatly improve the tightness of silicone adhesive pads. What are the specific methods for sticking gaskets? The prerequisite for making high-quality gaskets is definitely to do corresponding preparation work. For example, the main products of silicone gaskets are designed to achieve adhesive backing effect, which naturally cannot achieve good results. Therefore, it is required that the face of the silicone gasket be clean, dry, free of impurities, oil stains and liquids, and the surface of the gasket should be clean and smooth, without potholes, etc. There are usually two forms of silicone gasket backing, manual and fixture. Manual backing is mainly used for sampling and small batch trial production processing. It can be manually cut without a fixture die, and is not recommended for those with high requirements for edges and corners. Fixture dies are used for large-scale production processing. The premise of this method is that the silicone gasket processing manufacturer needs to prepare the mold opening method in advance, and the main method is self disassembly. After applying the backing adhesive, the edge can be removed by using a die. This processing technology has high precision and fast efficiency. Pressure is a secondary issue, and the usual debonding phenomenon is likely due to the magnitude of pressure. To achieve a good backing effect, pressure needs to be applied to the 3M adhesive and bonding surface to ensure sufficient contact and bonding between the adhesive paper and the gasket. Manual pressure is usually not as good as a scraper, and a scraper is not as good as a pulley. Different pressure instruments are used for different liquid machines and silicone gaskets with different requirements. The process of backing silicone gaskets is not complicated, and there are usually several reasons that can cause problems with the backing. In addition to the raw materials of the silicone gasket manufacturer and the 3M adhesive paper material, they are basically within the controllable range. Therefore, choosing a high-quality gasket supplier and materials is certainly important!

Some consumers have found that the edges of silicone products are damaged and cracked after purchasing them, which often troubles many friends and leads to a certain level of awareness and demand for silicone products in the future, resulting in a lower purchase rate. However, addressing the issue of edge damage in silicone products is not a last resort. The edge damage of silicone products is called "bursting edge" in the silicone products industry, which is mainly caused by several phenomena. During the use of the product, the misalignment phenomenon is caused by severe stress and the influence of the mold, resulting in slight damage to the silicone product and gradually increasing wear in the future. Secondly, the product itself has its own damage phenomenon. During the production and processing of silicone manufacturers, product damage is caused by temperature and material fixing problems. In addition, the hardness, softness, and curvature of the product also have a certain impact. Therefore, the causes of product damage can be controlled in various aspects! 1.Hardness issues are common in low hardness silicone products, and the main phenomenon of low hardness lies in the parameter adjustment of silicone product manufacturers, such as the temperature and secondary exhaust of the machine. Therefore, it is important to set the parameters of the machine, reduce the temperature, shorten the vulcanization time, and control the molding processing time of the product just at the stage of curing completion. If the time is too long, the raw material in the machine will expand, causing separation at the parting position and leading to cracking. 2.Raw materials are the key to silicone products. If the raw materials are not mixed for a certain period of time during the production process or if the added additives are insufficient, it may lead to various problems in the production process, such as edge bursting, poor fluidity, product bulging and deformation, etc. 3.The structure is relatively complex, and the phenomenon of edge breakage in products is also relatively large. In addition to hardness, the phenomenon of edge breakage in silicone products is usually closely related to the structure of the product in cases of low hardness. For example, the product is relatively thick, has a certain curvature, and the parting position is at the high point of the product. Therefore, strict control of its parting position is required during product design. 4.The mold is the key to the edge damage of silicone rubber products. During the development of the mold, the problem of product damage has not been solved due to inconsistent and misaligned connections between the upper and lower parting points. Therefore, strict control is needed in mold processing. 5.Other exceptional factors can also cause product edge breakage, such as improper control of the weight of the rubber material (too heavy can lead to edge breakage, while too light can lead to material and corner shortages, so controlling the weight within a reasonable range can reduce the probability of edge breakage). Secondly, in the long-term production process without intervals, the mold temperature should be appropriately reduced to maintain a certain temperature range (spraying the mold with clean water to maintain the mold temperature without intervals)

The silicone wristband is not only comfortable to wear on the hand, but the pattern on the wrist strap is also very attractive. So how are these exquisite patterns or logos made and engraved? What processes do silicone product manufacturers need to use in the production of wrist straps?   1. Printing Silicone printing, in simple terms, refers to the printing process using screen printing. The basic principle is that the mesh holes in the graphic and textual parts of the screen printing plate can pass through silicone, while the mesh holes in the non graphic and textual parts cannot pass through silicone. Apply a certain pressure to the silicone using a scraper to squeeze it from the mesh holes in the graphic and text parts onto the substrate. 2. Glue filling First, shape the product and then apply glue onto it. The main components of glue are adhesive colloids and organic solutions. The function of adhesive gel is to act as a bonding agent. The sponge mainly relies on the volatilization of organic solutions to achieve expansion during gluing. So when pouring glue, try not to expose the sponge that has been coated with glue to the outside, as this will reduce the expansion effect of the organic solution on the sponge. 3. Fuel injection Applied to spray on the surface of silicone wristbands to improve gloss and enhance hand feel and font lifespan. The product after extinction treatment has the characteristics of smooth hand feel, matte surface, and friction resistance, which can protect the printed fonts on the wristband and and prevent dust on the surface. 4. Radium carving Laser engraving, also known as laser engraving or laser marking, is a process of surface treatment using optical principles. Laser engraving refers to laser engraving, which uses the light energy of a laser beam to cause chemical and physical changes in the surface material of silicone products on the wrist strap, leaving marks, or to burn off some of the material with light energy, revealing the desired etched graphics and text. According to different carving methods, it can be divided into dot matrix carving and vector cutting.

Silicone hose is also very common in daily life. It is made of silicone raw material and is a highly active adsorbent material with an open porous structure, strong adsorption ability, and the ability to adsorb various substances. At the same time, it also has stable chemical properties, is non-toxic and odorless, and is a very safe and environmentally friendly material. What causes the aging of silicone products? Due to the aging of silicone products, many mechanical components cannot operate normally under specific conditions. Below are a few analysis reasons for your reference.   1. The effect of heat Raising the temperature can cause thermal cracking or cross-linking of silicone products. But the basic function of heat is still activation. Improving the oxygen diffusion rate and activating the oxidation reaction, thereby accelerating the oxidation reaction rate of silica gel, is a common aging phenomenon called thermal oxygen aging. 2. The role of oxygen Oxygen undergoes a free radical chain reaction with silica gel molecules in silicone gel, causing molecular chains to break or over crosslink, resulting in changes in the properties of silicone rubber products. 3. Reasons for light The shorter the light wave, the greater the energy. The destructive effect on silicone is caused by high-energy ultraviolet radiation. Ultraviolet radiation can not only directly cause the breakage and cross-linking of silicone molecular chains, but also generate free radicals in rubber due to the absorption of light energy, triggering and accelerating the oxidation chain reaction process. 4. The role of ozone Ozone has much higher chemical reactive oxygen species and greater destructive power. It also causes molecular chain breakage, but the effect of ozone on silicone gel varies depending on whether the rubber is deformed or not. 5. The role of water The role of water has two aspects: silicone products are prone to damage when exposed to humid air, rain, or water immersion. This is because water-soluble substances and components such as water droplets in silicone are extracted and dissolved by water. 6. The effect of mechanical stress Under repeated mechanical stress, rubber molecular chains will break and generate free radicals, triggering an oxidative chain reaction and forming a mechanochemical process. 7. Other reasons include chemical media, valence metal ions, high-energy radiation, electricity, and biology.   Due to the stable chemical properties of silicone hoses, they are resistant to both high and low temperatures. Even when heated, they do not produce toxic substances or deform. The silicone hoses widely used in medicine are food grade silicone hoses that are non-toxic and odorless. The pacifiers commonly used by children are also made of silicone, which is a food grade silicone material and has characteristics such as drop resistance and easy cleaning.

In daily life and industrial applications, anti slip performance is a key consideration for many material choices. Silicone and rubber, as two common polymer materials, are often used in anti slip scenarios due to their good flexibility and grip. So, silicone anti slip or rubber anti slip? The answer to this question is not absolute and requires in-depth analysis from multiple dimensions. From the perspective of material properties, rubber and silicone have their own anti slip principles. The molecular structure of rubber gives it a high coefficient of friction on its surface, especially natural rubber and some synthetic rubber, which have a soft and elastic texture and can tightly adhere to the contact surface. In dry environments, rubber can provide excellent anti slip effect. For example, traditional rubber soles are designed with complex patterns to enhance friction with the ground, effectively preventing slipping. However, in special environments such as humidity and oil stains, the anti slip performance of rubber will significantly decrease. When it comes into contact with water, the surface is prone to become wet and slippery. Long term exposure to grease may also cause swelling, leading to changes in physical properties. In contrast, silicone exhibits unique anti slip advantages. The molecular structure of silicone is stable, and its surface has a certain degree of hydrophilicity. Even in humid environments, it can form a tight adsorption force with the contact surface. At the same time, silicone material itself is insoluble in oil and grease, and can still maintain good anti slip performance in oily environments. In addition, the surface microstructure of silicone can be optimized through special processes, such as adding concave convex textures and micro nano level rough surfaces, to further enhance friction. Experimental data shows that the specially treated silicone material has a friction coefficient on wet glass surfaces that is more than 30% higher than that of ordinary rubber, and its anti slip performance is particularly outstanding in extreme environments. It is worth noting that the anti slip performance of both silicone and rubber is closely related to the design and manufacturing process of the product. By optimizing surface texture and adding special anti slip particles, the anti slip effect can be further improved. Therefore, when choosing anti slip materials, in addition to considering the characteristics of silicone and rubber themselves, attention should also be paid to the specific design and usage scenarios of the product, and a comprehensive judgment should be made in order to select the most suitable anti slip product for safety protection.

In modern industry and daily life, silicone gaskets are widely used in many fields such as electronic appliances, food and medical care, machinery manufacturing, etc. due to their excellent performance, such as high temperature resistance, low temperature resistance, aging resistance, and good insulation. So, how are these seemingly ordinary silicone gaskets produced? The production of silicone gaskets begins with the careful selection of raw materials. High quality silicone rubber material is the key. It needs to have high temperature resistance, corrosion resistance, aging resistance and other characteristics to adapt to different application environments. If used in the field of food contact, it must also be food grade silicone material to ensure safety and reliability. Mold design and processing can be regarded as the core process of silicone gasket production. A mold is like a "template" for a product, and its design rationality directly determines whether the size accuracy and shape of the silicone gasket meet the standards. Dibo Silicone has a professional mold design team that uses advanced CAD/CAM technology for design. At the same time, during the mold manufacturing process, precision and surface quality are strictly controlled, effectively reducing production errors and scrap rates. And they will arrange the mold placement reasonably according to production needs to improve production efficiency. After the mold is opened, a trial mold will be conducted to carefully measure the product and verify it with the drawings to ensure the accuracy and reliability of the mold. Production molding vulcanization is a key step in giving silicone gaskets their final form. Common molding processes include compression molding, extrusion bonding, and liquid forming, each with its own applicable scenarios. Compression molding is the most common process, suitable for conventional sealing rings. By manually placing raw materials into molds, hot pressing and heating the materials to shape them, silicone gaskets of any structure such as rectangular, circular, and irregular can be produced; Liquid forming is suitable for complex and precision gaskets. The rubber material is pressed into the hot mold cavity through the injection nozzle of the injection machine for molding. The product material has good texture and good self disassembly, but the mold and material costs are relatively high; Extrusion molding is suitable for the production of large silicone gaskets. The extruded long sealing strip is cut into the required length and bonded into a circle. Although there may be gaps at the joint that affect the sealing effect, the advantage is that the size is not limited. Quality inspection runs through the entire production process. From strict inspection of raw materials upon arrival at the factory, to inspection during the production process, and to comprehensive testing of finished products, every step must not be neglected. Visually inspect whether the surface of the silicone gasket is flat and smooth, and whether there are defects such as bubbles and cracks; Use professional instruments to measure thickness, length, width, etc. for size inspection to ensure consistency with design requirements; Performance testing evaluates the key performance of silicone gaskets, such as high temperature resistance, aging resistance, and sealing. After production and testing are completed, the silicone gasket will enter the packaging process. From raw material preparation to final product, the production of silicone gaskets embodies the crystallization of numerous processes and technologies. Every production process is crucial, as they together ensure the excellent quality of silicone gaskets, enabling them to play an important role in different fields and provide reliable support for people's lives and industrial production.

Why do bubbles appear on the surface of silicone products, and what should be done if bubbles appear? What is the reason for this? Below, silicone product manufacturers will explain the solutions to the occurrence of bubbles in silicone products:   The most important thing is to consider the issue of silicone vulcanization process. After carefully studying and practicing the three elements of silicone vulcanization, what we should consider is: 1. Measuring the real mold temperature. How many parts of rubber vulcanizing agent have been added. 3. Check if the vulcanizing agent has failed, and cover the rubber material with a thin film. The specific operation method is as follows: 1.Control the temperature of silicone molds: Generally, the temperature of the upper mold is high and the temperature of the lower mold is low, because the lower mold needs to discharge materials, and if the temperature is too high, it is easy to burn. 2.It is well known that sulfurizing agents are prone to volatilization, so it is important to take precautions. 3.The dosage of vulcanizing agent added should be appropriate. 4.The vulcanization time can be appropriately extended 5.You can consider spraying some detergent solution. The above solutions for the appearance of bubbles on the surface of silicone products are for reference only. For more information on silicone process issues, please continue to follow us.

We can see that the patterns on silicone screen printing are very beautiful, so there must be someone interested in the process of silicone screen printing. Therefore, the editor will provide a detailed introduction to the silicone screen printing process. Screen printing is the earliest printing method. Screen printing is the abbreviation for "screen printing". Because screen printing requires a mesh board, it is also called screen printing. Generally, silk screen printing ink is thicker and brighter, and the printed patterns have a three-dimensional effect. Screen printing can also print finer lines and is suitable for large-area printing. Screen printing is the process of stretching silk fabrics, synthetic fiber fabrics, or metal wire mesh onto a frame, and using manual coating or photochemical plate making methods to produce screen printing plates. Modern screen printing technology uses photosensitive materials to produce screen printing plates through photographic plate making methods. Screen printing is the process of transferring ink through the mesh holes of graphics and text onto a substrate, forming an image that is identical to the original image. Silk screen silicone is a special type of silicone that is printed through screen printing.   Now let's talk about how many times do silk screen silicone need to be printed? Silk screen silicone is divided into manual printing and machine printing. Manual printing requires multiple prints to form, but the printing is too slow and the production capacity is not high. Because it is manually scraped, some patterns may have slight ghosting if not careful. Screen printing can only print one color at a time. If color matching is required, first print the first color, then dry it, adjust the position of the screen plate, and then print the second color. And machine printing only takes one time to form. Silk screen silicone has the characteristics of environmental protection, non delamination of printing colors, multiple printing effects, good adhesion, delicate hand feel, excellent performance, non-toxic and harmless. After screen printing, the three-dimensional effect of the product will be enhanced and become more beautiful. Mainly because silk screen silicone is non-toxic and harmless, there is no need to worry about safety issues.

Small components are used in every industry, so there are also many things that happen around us due to small losses. Sealing and protective equipment in various industries cannot do without the assistance of silicone accessory materials. The role and influence of silicone components can play a great role in the combination of many products, and the adjustment of softness and hardness can completely affect any functional problems. Therefore, if the hardness of silicone accessories is not selected properly, it can also cause quality problems. What are the effects of different hardness and softness on functionality!   Spare parts are mainly used for assembly, sealing, shock absorption, protection, and intermittent use, while the softness and hardness values of silicone have drawbacks in different functional aspects. In terms of sealing function, if the hardness value of silicone sealing accessories is high and the folding and bonding strength is low, it is likely to cause idle leakage, and the service life will be affected after long-term stress aging, resulting in damage and cracking. A low hardness value can provide cushioning for functionality, and reducing hardness as much as possible in waterproof function can achieve more effective waterproof effect. However, the material and thickness of the product must be appropriate to achieve good extension and rebound strength.   In terms of buffering and shock absorption, silicone products need to achieve a medium to high hardness value as much as possible. Due to the influence of force, a low hardness value of the product may lead to insufficient shock absorption effect and failure to achieve functionality. Secondly, after the low hardness silicone accessories are assembled, they are likely to achieve the effect of active buffering and shock absorption, leading to looseness and detachment. Increasing the hardness value not only improves the firmness, but also achieves buffering effect due to the high hardness value.   Assembly, many silicone accessory manufacturers understand that sealing accessories are assembled from different materials, and the completeness of assembly is also affected by hardness, leading to functional problems of the product. High hardness materials are not easy to assemble, and the higher the hardness, the smaller the tensile rebound. Therefore, when assembling high hardness accessories, try to minimize their tensile strength. Low hardness assembly is better, but attention should also be paid to the problem of excessive tensile extension.

When it comes to silicone, I believe many friends know about it. In the medical plastic surgery industry, few people know how effective it is and whether it can be achieved. With the increasing awareness of safety and environmental protection, silicone materials have now become an indispensable material in various industries and our daily lives. The things you use basically contain silicone material. Have you noticed?   Silicone material is a major category of rubber, which is mainly composed of several combinations of silicone rubber, white carbon black, silicone oil, silane coupling agent, etc. Each component has a different type of silicone material. Currently, silicone material is classified as ordinary grade silicone, which is mainly used in many component silicone products and sealing products. For example, silicone buttons, sealing rings, silicone hoses, silicone plugs, and gaskets.   Medical silicone: The raw materials and purity of this type of product are much higher than the original two types. Its silicon molecule white carbon black and silane coupling agent have better purity, and the silicone products made from them have higher long-term stability when in contact with the skin. At present, our common medical silicone is also widely used, and its thin film is used for human surgical experiments on medical devices and products. Such as silicone syringe plugs, silicone infusion tubes, and oxygen caps. What can silicone do? It has already appeared in our lives. Silicon products are basically present in places with soft rubber, so its function can be discovered at any time when you are not paying attention.
