Do you know the production technology of lip seals? Lip seal Lip seals are also one of the types of seals we commonly use. Because seals are widely used, there are many types and performances of rubber seals. Today, Xiao Bian will talk about the production technology of lip seal products. At present, the gap production technology of rubber lip seals includes: the "mixing" process of seal production technology; This seal production process is widely used in internal mixer to manufacture rubber compound, automatic weighing and blending, automatic feeding and automatic mixing. Lip seal So, what is the production process of lip seal products? The "mixing" process of seal production technology: This seal production process widely uses internal mixer to manufacture rubber materials, automatic weighing and blending, automatic feeding, automatic mixing and discharging, with high production efficiency and good rubber quality. The "semi-finished product manufacturing" process of the seal production process technology: the preforming machine is a commonly used semi-finished product manufacturing machinery. It is characterized by semi-finished product weight standard, regular geometry, high production efficiency, saving rubber, high product qualification rate, but also to achieve high temperature rapid molding vulcanization process is a necessary means. There are also some seal manufacturers to introduce the seal production equipment, but most seal manufacturers still use the cutting machine and manual cutting semi-finished products.

How to produce silicone key laser carving process

How to produce silicone key laser carving process

2021-07-26 10:53:47

Do you know the reason why silicone key laser carving technology is popular? Silicone Key Laser Carving Process Because today's silicone key industry, the use of laser carving process is very common. In recent years, the laser engraving technology of silicone keys has been used more and more in the printing field; compared with traditional mechanical engraving, chemical etching, screen printing, ink printing and other methods, laser engraving technology has more operating costs. Low, high flexibility, precise control, easy operation and other outstanding features. Do you know what is the meaning of laser carving in the laser carving process of our silicone keys? It is usually called marking in the industry. It is also a treatment method for the surface treatment process of silicone keys, but after we have used the laser carving process of silicone keys, it is difficult to distinguish, because its touch feeling is not strong, although it has a little concave-convex feeling, it is very slight. Silicone Key Laser Carving Process We can put it in a popular way. Simply put, the laser carving process of silicone keys is actually a kind of spraying some specified color oil or characters and graphics on the surface of silicone keys. When our silicone products need laser carving process, they must be sprayed with oil first. For example: a silicone button, the surface is black, the character is red; according to this appearance requirements. We must first prepare the silicone keys that need laser engraving process, and plan to determine the background color of our silicone keys before molding. It is recommended to generally adjust to transparent silk screen printing, and then silk screen print red silk bottom on the surface of the silicone keys or directly spray red ink. At this time, the concentration of red ink should be low, or the thickness of silk screen spraying should be thin, so as to facilitate light transmission. Silicone Key Laser Carving At this time, we should screen or spray the silicone keys. When we can see the red characters, the bottom of the ink should be red, so the surface of the silicone keys can transmit light. Because the ink is at the top, it will not cause light leakage in the area other than the characters on the silicone keys.

Do you know what are the characteristics of the seal material? Analysis of Material Characteristics of Seals In fact, there are many kinds of seal materials, among which there are many common ones. Today, I will share with you what are the characteristics of seal materials. Because the use of seals is very wide, it will be for a variety of industries, uses, performance, etc., to produce seals. There are many kinds of sealing materials, such as silica gel material, fluorine material, Ding Qing material, styrene butadiene material, etc. So, what are the characteristics of these materials? Analysis of Material Characteristics of Seals Silicone material: The most prominent features of silicone material are temperature resistance, weather resistance, electrical insulation, elongation, tensile strength and other excellent characteristics, so the seals of such materials are common in many industries. Fluorine material: generally refers to the seal of this material in the synthesis of fluorine olefin copolymer, fluorine material has good resistance to strong acid, heat resistance, corrosion resistance, superheated water resistance, superheated steam and other excellent characteristics; So it is suitable for use in environments with strong acidic substances and relatively harsh. However, fluorine material has great difficulty in processing technology, and the cost is relatively high. Ding Qing material: Ding Qing material is a more common type of seal material, because Ding Qing material has excellent oil resistance and aging resistance, and has good wear resistance. At the same time, it is good for mineral oil, animal and vegetable oil, Aliphatic hydrocarbons have excellent corrosion resistance, so their uses are relatively wide. Analysis of Material Characteristics of Seals What are the characteristics of the seal material? This is the end. I believe you are all clear now!

Silicone sealing ring for the environment adaptability is very strong, it is placed in the strong temperature heating, can be very good to maintain its original shape and state, do not completely deformation, in the high temperature environment will not produce any harmful material composition. Silicone rubber has a wide range of applications, and can make many model products and industrial supporting products, such as various medical grade silicone tubes, bottle straws, silicone strips, pacifiers, silicone tableware, O-rings, gaskets, cups, oil seals, valves, shock absorbers and diaphragms, medicine bottles, silicone sealing rings, etc. Nitrile sealing ring rubber has very good oil resistance. Its oil resistance is second only to polysulfide rubber and fluorine rubber, and has very good wear resistance and air tightness. However, nitrile rubber also has its limitations. Its disadvantages are that it is not resistant to ozone and aromatic, halogenated hydrocarbons, ketones and ester solvents, and is not suitable for insulating materials. Nitrile rubber has better heat resistance than styrene butadiene rubber and chloroprene rubber, and can work for a long time at 120 ℃. Its air tightness is second only second only butyl rubber, the performance of nitrile rubber will be affected by the content of acrylonitrile, with the increase of acrylonitrile content, nitrile rubber tensile strength, heat resistance, oil resistance, air tightness, hardness increased, but elasticity, cold resistance decreased. Silicone sealing ring is not resistant to oil and is not suitable for most thick-shrunk solvents, oils, thick-shrunk acids and diluted sodium hydroxide. Silicone sealing ring has good cold resistance, ordinary rubber is generally -20 ℃-30 ℃, while silicone sealing ring still has good elasticity at -50 ℃-60 ℃, and some special low-temperature resistant silicone can also withstand low temperature. It has high wear resistance, and has the function of automatic elastic compensation on the worn part of the working sealing ring surface, thereby increasing the service life of the sealing member. It has good self-lubricating performance, so it can be safely used in some seals that cannot be lubricated. The silicone key has the characteristics of simple and convenient installation, because its structure is relatively simple compared to other types of seals.

Now there are many kinds of sealing rings, there are all kinds of sealing rings in the market, large and small, thousands of kinds, always make people feel dazzling, but the sealing ring material is now made of silicone products and rubber products, and there are many kinds of sealing rings. The shrinkage of silicone key silicone sealing ring changes with the increase of the density of the rubber content of the vulcanized silicone material, and the shrinkage of the silicone rubber sealing ring also changes with the increase of the hardness of the silicone raw material. Usually, the silicone sealing ring of the heat preservation box that everyone sees is placed in the groove of the small box in the heat preservation box to achieve sealing and heat preservation effect. Few of them are placed outside the small box. My silicone sealing ring of the heat preservation box happens to be placed outside the small box and is in contact with the whole heat preservation box. Can such placement achieve the sealing effect of the sealing ring. In fact, the placement of the silicone sealing ring of this heat preservation box is the same principle as that of other lunch boxes and water cup sealing rings, which achieves the effect of sealing and heat preservation. The placement of the silicone sealing ring outside the small box in contact with the whole heat preservation box essentially seals the whole heat preservation box instead of a single small box. Such placement can make the whole heat preservation box achieve better heat preservation effect. Another advantage of this insulation box silicone sealing ring is that it makes the inside of the insulation box cleaner and has a long service life, because the silicone sealing ring seals the whole insulation box, which is equivalent to blocking the external fine dust from the outside of the insulation box, while the silicone sealing ring is only placed in a small box, and the inside of the whole insulation box is not protected, which is easy to allow dust to enter, thus requiring frequent cleaning. The insulation box is often cleaned with water, thus losing the initial insulation effect, over time, it needs to be replaced with a new heat preservation box. Silicone ring is a kind of sealing ring. Silicone is a kind of rubber material. Because of its special performance, wide temperature range and excellent chemical properties, it is a special rubber together with fluorine rubber. Silicone is widely used in the production of various seals. Silicone waterproof ring is also commonly known as silicone O-ring, which belongs to a product classification of silicone products. Silicone is a ring product made of silicone. Silicone waterproof ring is mainly used for occasions requiring waterproof and sealing.
