Manufacturers supply __ (add written information title) ___, the following description of the product's performance and do set forth a specific, low-temperature resistance import O-ring: NBR low temperature under normal circumstances only -20 ℃ , under the circumstances, or a short moment can reach -40 ℃. And some customers in need of long-term use of low-temperature resistance temperature at -40 ℃ or less, in which case you need to use a special rubber compound to produce nitrile rubber. OTP companies can provide low temperature reached -45 ℃ nitrile rubber O-rings for you. The company uses pure imported glue plastic material in the selection of materials, the reliable source to ensure product quality and stability. Second, the surface treatment of import O-ring: OTP company owns the world's most advanced processing technology, the use of imported produce high-precision CNC machining centers of O-ring mold, with the mold out of the product, the product can reach very high surface finish, parting line can do little, barely visible mold clamping line, if you have special requirements, needs no edges, we can process mill process again, so that the product clamping line removal, so as to achieve without flash. Give your seal products to be perfect. Three, O-ring trimming divided into manual, mechanical and refrigeration and other categories: 1. Manual trimming. The operator holds the tool, along the outer edge of the product, will repair to the overflow edge gradually. This is the most primitive way. Inefficient, difficult to guarantee quality, especially for small size, high precision O-ring is difficult to do a thorough, on the net, and it is easy to damage the product and the connected portion of the body and the overflow edge. Often leaving teeth marks, nicks, leaving oil spills, leaks and other problems affecting sealing aftermath. In addition. Manual trimming operation proficiency depend also prominent. 2. Mechanical trimming. In order to improve efficiency and quality, it has a mechanical trimming. Common is dedicated electric with a rotary blade trimmer. Match the height of the blade used and product size required. If the inner and outer edges of the product have overflow edge. It can be designed to be double-edged, more cutting edge. In order to achieve a complete. Mechanical trimming of precision than manual trimming, efficiency has doubled, especially for a product in terms of multi-cavity mold, in accordance with the arrangement and distribution of products designed to match the tool. Until after the mold product. You can put full-page, once punching. In the heat of cooperation, one can repair dozens. The key is punching the temperature must be controlled, prevent the excessive adhesion. 3. Frozen trimming. The vulcanized good product together with scrap, were in addition to the side under refrigeration. The technology was developed by Japan's Showa carbonate and co-inventor of the domestic 昭凌 improved precision for decades, with the freezing medium of choice, updating and improving the mechanical action, freezing trimming also experienced several improvements, maturity and perfection , work efficiency and machining quality has been noticeably improved. Fourth, import O-ring tensile strength or elasticity: tensile strength or elastic ring is good or bad, is a direct response to one of the important criteria used in rubber products good or bad, but also affect the performance of an important part of the sealing ring. Under normal circumstances, the flexibility of plastic material good tensile strength, the higher, the longer the life of the product. How to improve the tensile strength of the product that it? There are two ways, one is the use of imported raw material nitrile rubber. Second, the use in the production process of vulcanization of peroxide vulcanizing manner. If imported rubber, vulcanized with peroxide in the way, so produced by the O-ring will be more advantageous in every performance. Wall Taiwan factory can provide you with top imported materials and peroxide vulcanizing rubber processing mode. Fifth, the import O-ring in the fuel tank to the application of: YX hole type O-rings, the product uses: for reciprocation hydraulic cylinder piston seal. Scope: TPU: general hydraulic cylinders, general equipment hydraulic cylinder. CPU: engineering machinery hydraulic cylinder and high-temperature, high pressure cylinders. Material: Polyurethane TPU, CPU, rubber. Hardness: HS85 ± 2 ° A Working Temperature: TPU: - 40 ~ + 80 ℃, CPU: -40 ~ + 120 ℃ Working pressure: ≤32Mpa Working medium: hydraulic oil, emulsion. Shaft YX type O-rings, the product uses: for sealing scope reciprocation hydraulic cylinder piston rod: TPU: general hydraulic cylinders, general equipment hydraulic cylinder. CPU: engineering machinery hydraulic cylinder and high-temperature, high pressure cylinders. Material: Polyurethane TPU, CPU, rubber Hardness: HS85 ± 2 ° A Working Temperature: TPU: - 40 ~ + 80 ℃ CPU: -40 ~ + 120 ℃ Working pressure: ≤32Mpa, working medium: hydraulic oil, emulsion. YX-type hole blocking O-ring, the product uses: YX-ring when with the use of this standard applies to the working pressure greater than 16MPa cylinder, the cylinder or eccentric force, acts to protect seals Operating temperature: -40 ~ + 100 degrees. Working medium: hydraulic oil, emulsion, aquatic hardness: HS 92 ± 5A Material: Teflon. Sixth, on the overall, we have every reason to believe that OTP company can provide you with quality wear resistance, low temperature, high tensile strength, flexibility, and so on imports of high-quality O-ring to fit your product Inoue smallpox help on hand.
