We sell various seals, hydraulic, pneumatic, and fluid control products and components. In terms of seals, Yongxin offers hydraulic and pneumatic sealing products, including dynamic seals, static seals, sealing rings, oil seals, gaskets, packing, etc.O-rings (also known as O-rings, O-rings, O-rings) are ring-shaped mechanical gaskets, which are ring-shaped elastomers with a circular cross-section. They are usually fixed in a groove and compressed by two or more components during assembly, thus creating a sealed interface. Because of their low price, simple manufacturing, reliable function, and simple installation requirements, O-rings are common mechanical designs for sealing. They can withstand pressures of tens of Pascals (thousands of pounds). O-rings can be used in static applications as well as in dynamic applications where there is relative movement between components, such as the shaft of a rotary pump and the piston of a hydraulic cylinder.Rubber O-ring seals are mainly used to manufacture oil-resistant rubber products. The acrylonitrile content (%) in rubber O-ring seals is divided into five types: 42-46, 36-41, 31-35, 25-30, and 18-24. The higher the acrylonitrile content, the better the oil resistance, but the cold resistance decreases accordingly. It can be used in air at 120°C or in oil at 150°C for long periods. In addition, it has good water resistance, air tightness, and excellent bonding properties. It is widely used in the manufacture of various oil-resistant rubber products, various oil-resistant gaskets, spacers, sleeves, soft packaging, soft hoses, printing and dyeing rubber rollers, cable rubber materials, etc., and has become an elastic material in industries such as automotive, aviation, petroleum, and photocopying.<img src="https://img-i-album.toocle.com/view/2022/04/06/14/624d2ea903414.png" style="max-width:100%;"/>NBR rubber O-ring seals have excellent oil resistance. The typical NBR structure has about 78% trans configuration. Due to the presence of cyano groups in the molecular chain structure of NBR rubber O-ring seals, their oil resistance (such as resistance to mineral oil, liquid fuels, animal and vegetable oils, and solvents) is better than that of natural rubber, chloroprene rubber, and styrene-butadiene rubber. Compared with other rubbers, NBR has a wider range of use temperatures, with a long-term use temperature of 120°C. At the same time, NBR rubber O-ring seals have good low-temperature performance, with a glass transition temperature as low as -55°C.NBR rubber O-ring seals have good chemical stability and processing performance. As the acrylonitrile content in their structure increases, the relative density increases, the vulcanization speed accelerates, the tensile strength improves, but the rebound performance decreases, and the cold resistance deteriorates. Because the cyano groups in NBR rubber O-ring seals are easily polarized by electric fields, the dielectric properties decrease, making them semiconductor rubbers. NBR rubber O-ring seals can be divided into five categories based on ACN content: ultra-high, high, medium-high, medium, and low acrylonitrile. The production methods are divided into continuous and intermittent polymerization. Continuous polymerization is usually used for large-scale production with low consumption. Intermittent polymerization is suitable for multi-variety and small-batch production, with high engineering consumption.Although rubber has excellent physical and mechanical properties and processing performance, its long-term performance in acidic gasoline and high-temperature (150°C) environments is not as good as that of fluororubber and acrylate rubber. Therefore, hydrogenated rubber (HNBR) with excellent performance has been developed. In addition, rubber with extremely high cold resistance and high purity, as well as carboxylated rubber (XNBR), have also been developed.Rubber O-ring seals are light brown elastomers with a molecular weight of about 700,000. Due to the strong polar CN group, they have excellent stability against aliphatic hydrocarbon oils and gasoline. They are classified based on ACN content:High rubber: ACN content 36%-42%Medium-high rubber: ACN content 31%-35%Medium rubber: ACN content 25%-30%Low rubber: ACN content below 24%<img src="https://img-i-album.toocle.com/view/2022/04/06/32/624d2eba61732.png" style="max-width:100%;"/>Rubber O-ring seals have good heat resistance. Their heat resistance is better than that of natural rubber and styrene-butadiene rubber, with a long-term use temperature of up to 100°C, and they can be used at 120°C for 40 days. [1]① The ozone resistance of O-ring seals is worse than that of CR but better than NR.② O-ring seals are reinforced to give the rubber better physical and mechanical properties and wear resistance.③ When the acrylonitrile content of the rubber is 39%, the air tightness of O-ring seals is comparable to that of IIR rubber, and the air tightness is good.④ The low-temperature flexibility of O-ring seals is average.⑤ O-ring seals have excellent anti-static properties.⑥ O-ring seals have good plasticizing effects with polar esters.⑦ O-ring seals have good compatibility with polar substances, such as PVC, alkyd resins, and nylon.⑧ O-ring seals have low self-adhesion and generate more heat during the mixing process.Excellent Oil ResistanceRubber O-ring seals are one of the excellent rubbers with comprehensive properties such as oil resistance, physical and mechanical properties, and chemical resistance. Making full use of these characteristics can meet various applications. Among general-purpose rubbers, NBR rubber's resistance to benzene, petroleum-based oils, and non-polar solvents is far better than that of non-polar rubbers such as NR, SBR, and IIR, and also better than the polar CR. However, the performance of rubber in polar solvents and polar oils is not good enough.After-Sales Service:Yongxin Seals provides material certificates for all products, allowing customers to buy and use with confidence, without any worries!

Heat-curing types include methyl silicone rubber (MQ), methyl vinyl silicone rubber (VMQ, the most widely used with numerous product grades), methyl vinyl phenyl silicone rubber (PVMQ, resistant to low temperatures and radiation), as well as nitrile silicone rubber and fluorosilicone rubber, among others. MQ is a colorless, transparent, highly viscous, plastic linear polymer compound, with a backbone composed of silicon and oxygen atoms, and methyl groups attached to the silicon atoms. Its molecular weight ranges from 500,000 to 800,000. VMQ is a colorless, transparent, highly viscous, plastic linear polymer compound, with a backbone composed of silicon and oxygen atoms, and methyl and vinyl groups attached to the silicon atoms. Its molecular weight ranges from 500,000 to 800,000. PVMQ is obtained by introducing diphenyl siloxane segments or methylphenyl siloxane segments into the molecular chain of vinyl silicone rubber.<img src="https://img-i-album.toocle.com/view/2022/02/27/39/621aded5eca39.png" style="max-width:100%;"/><img src="https://img-i-album.toocle.com/view/2022/02/27/c1/621aded61d9c1.png" style="max-width:100%;"/><img src="https://img-i-album.toocle.com/view/2022/02/27/a8/621aded637fa8.png" style="max-width:100%;"/>000Temperature range: -60°C (special down to -115°C) to 204°C (special up to 260°C)O-ring material selection: Silicone rubberSilicone rubber refers to rubber whose backbone consists of alternating silicon and oxygen atoms, with silicon atoms typically bonded to two organic groups. Ordinary silicone rubber mainly consists of siloxane segments containing methyl groups and a small amount of vinyl groups. The introduction of phenyl groups can improve the high and low-temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can enhance its temperature and oil resistance.Silicone rubber has good low-temperature resistance and can generally operate at -55°C. With the introduction of phenyl groups, it can withstand temperatures as low as -73°C. Silicone rubber also excels in heat resistance, operating long-term at 180°C and withstanding temperatures slightly above 200°C for several weeks or longer while retaining elasticity. It can momentarily endure temperatures above 300°C. Silicone rubber has excellent gas permeability, with an oxygen transmission rate that is among the highest in synthetic polymers. Additionally, silicone rubber is physiologically inert and does not cause blood clotting, making it widely used in medical applications.High-temperature performance. The most notable feature of silicone rubber is its high-temperature stability. Although its strength at room temperature is only half that of natural rubber or some synthetic rubbers, at temperatures above 200°C, silicone rubber can maintain a certain degree of flexibility, resilience, and surface hardness, with no significant changes in mechanical properties.Properties1. Low-temperature performance. The glass transition temperature of silicone rubber is generally between -70°C and -50°C, with special formulations reaching -100°C, indicating excellent low-temperature performance. This is highly significant for the aviation and aerospace industries.2. Weather resistance. The Si-O-Si bonds in silicone rubber are highly stable against oxygen, ozone, and ultraviolet light, providing excellent weather resistance without the need for additives.3. Electrical properties. Silicone rubber has outstanding insulation properties, with excellent corona and arc resistance.4. Physical and mechanical properties. At room temperature, the physical and mechanical properties of silicone rubber are inferior to those of general-purpose rubbers. However, at high temperatures of 150°C and low temperatures of -50°C, its physical and mechanical properties surpass those of general-purpose rubbers.5. Oil and chemical resistance. Ordinary silicone rubber has moderate resistance to oil and solvents.6. Gas permeability. At room temperature, the permeability of silicone rubber to gases such as air, nitrogen, oxygen, and carbon dioxide is 30-50 times higher than that of natural rubber. more>

Resistant to most oils and solvents, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils. Suitable for diesel engines, fuel systems, and sealing needs in chemical plants. Not recommended for use with ketones, low molecular weight esters, and nitrated mixtures. General operating temperature range: -20~250°C.Food grade silicone is an inorganic polymer colloid material formed by the condensation of silicic acid, with the main component being SiO2•nH2O, content above 98%. It is non-toxic, odorless, chemically stable, and does not react with any acids, alkalis, or salts under normal conditions except for caustic alkalis. It can withstand high temperatures up to 220°C, can be used in microwaves, and has no adverse effects on the human body. Compared to other materials, it is safer and healthier. Simply put, food-grade silicone has strong stability and better meets health and safety requirements. In fact, food-grade silicone is already found in ordinary households, commonly seen as sealing gaskets in pressure cookers, which are easy to clean and non-toxic.Applications of Food Grade Fluorine Rubber Sealing Rings:Fluoroelastomers are often used in the automotive industry, chemical processes, aerospace, and many industrial applications due to their excellent flame retardancy, air tightness, high-temperature resistance, oil resistance, solvent resistance, combustion resistance, chemical resistance, and weather resistance. Notably, fluoroelastomer seals can be used under high vacuum conditions, below 1.33*10^-7 Pa, where other rubbers cannot be used for sealing.

Specific factors and solutions are as follows:II. Operational FactorsTap not perpendicular to the workpiece end faceIf the tap axis is not perpendicular to the workpiece end face during tapping, uneven force distribution can cause thread deviation. Adjust the tapping angle to ensure the tap is perpendicular to the workpiece end face.Uneven hand force applicationDuring manual tapping, uneven force or unstable posture can easily cause the tap to tilt. It is recommended to hold the tap steadily with both hands, apply force evenly, and keep the tap axis aligned with the workpiece center.Inaccurate equipment alignmentIf the hole center is not aligned during mechanical tapping, the tap may deviate from the axis. Check the equipment's positioning accuracy to ensure the tap aligns with the hole center axis.Riveting Machine Zhuhai Rivet Machine Direct Control Cabinet Computer CaseIII. Material CharacteristicsInternal material defectsDefects such as sand holes or inclusions in thin sheet materials may hinder normal tap cutting, leading to deviation. Inspect the material surface quality before tapping and remove surface impurities.Uneven material hardnessLocal variations in hardness in thin sheets may cause unbalanced force on the tap. It is advisable to select tap types suitable for the material (e.g., cobalt high-speed steel taps) and control cutting speed to reduce wear.Riveting Machine Zhuhai Rivet Machine Direct Control Cabinet Computer CaseIV.

Product Description:Zhongshan wholesale riveting machines, manual tapping efficiency is lowRivets generally outperform self-tapping screws in structural strength and fastening effectiveness, particularly excelling in scenarios involving shear force and one-time permanent fastening; whereas self-tapping screws, due to their detachability, are more suitable for light-load applications or situations requiring frequent maintenance.Specific differences are as follows:Zhongshan wholesale riveting machines, manual tapping efficiency is low1. Fastening Principle and Strength.Rivets achieve a tight connection through their own deformation (such as expansion or bending), without the need for additional components. This irreversible connection method provides higher tensile and shear strength (e.g., the tensile strength of pull rivets can exceed 30,000 Newtons).Self-tapping screws rely on threaded insertion for fixation and are prone to loosening over time due to vibration or external forces, with relatively weaker shear resistance.Zhongshan wholesale riveting machines, manual tapping efficiency is low2. Applicable Scenarios.Rivets are suitable for:Structures subjected to significant shear forces (e.g., heavy steel structures, aircraft skins);One-sided installation scenarios requiring one-time permanent fastening (e.g., ceiling installations, metal component connections).Self-tapping screws are suitable for:Thin materials or double-sided installation (e.g., furniture assembly, lightweight wall construction);Situations requiring frequent disassembly or maintenance (e.g., internal connections in electronic products).Zhongshan wholesale riveting machines, manual tapping efficiency is low3. Installation Characteristics.Rivets install quickly and have a clean break, but once fixed, they cannot be reused;Self-tapping screws install slightly slower and may have uneven surfaces, but they can be repeatedly disassembled and reassembled.In summary, if "sturdiness" is the core requirement and long-term maintenance costs are not a concern, rivets are the preferred choice; if flexibility and lightweight connections are needed, self-tapping screws are more appropriate. more>
