China's production of rubber rollers companies conservatively estimated at more than 500, from the appearance Cots though very simple, yet diverse, very complex, use can be described as extremely broad. Use can be divided paper roller, printing roller, textile roller, printing roller, leather roller, hulling rolls, metallurgy Cots; as companies established there has, technical strength, production capacity, quality level uneven. Large enterprises have abundant capital, advanced technology, product variety, covering a wide range of industries, others are basically small and medium enterprises with an industry rubber roller manufacturing. Cots different application areas, it determines its Size is different. The papermaker cot for up to 10m, the quality of more than 14 tons; rolled rubber roller diameter of 2m, the quality of more than 20 tons. Cots and camera quality is less than 30 grams, a diameter of only 8mm. Paper Roller is one of the earliest industrial rubber roller products, mainly used for making pulp and paper industry, paper machine and paper processing coated Koki three. Due to the larger size, generally by large manufacturing production, large rubber roller symbol, has historically been long dominant. In the past, paper Cots Cots market accounted for more than 30% after the sharp expansion of the printed output OA and other Cots, now substantially been reduced to 5% to 15%. At the same time, paper and rubber rollers used to be consumable parts on the paper machine, which normally takes only changed every 3 to 5 years, but with the continuous improvement and improve the quality and performance of rubber roller, now generally have 8 to 10 years to replace a , so the market demand is declining. These are large rubber roller manufacturers need to pay attention. Metallurgical Cots: In recent years, due to rapid economic development, a substantial increase in steel requirements, China has become the world's largest country in the amount of steel consumption, coupled with advances in metal sheet rolling technology, the rapid development of metallurgical Cots, market share more than the paper rollers. In the United States, Europe, Japan and other steel producing countries, Cots rolling rubber consumption has accounted for 20% to 25%, second only to the printing rollers and OA Cots, (OA office equipment Cot mainly refers to the copier. Plastic machine fax machine printer and other equipment with plastic rollers) has become one of the mainstay products Cots. Metallurgical Cots their role can be divided pinch roller, roller linkage, guide roller, straight roller, pinch rollers, looper tension roller and many other types, mostly for use in direct contact with the state, such as sheet steel. Electrolytic washing apparatus, a continuous pickling apparatus, plate coating device galvanizing means, means tin, chrome means special surface treatment apparatus, silicon steel plate means, slitting means, measuring means, shearing means, grinding devices and other production Basic has a shadow pipeline metallurgical cots. In addition, coil preparation equipment, rolling around machine devices are also used rolling rollers. A number of rolling rubber roll rolling production line is now as high as 500 to 1000. The current production of metallurgical Cots enterprises mainly in the Hebei region, the market remained stable. Cots for printing and dyeing machinery, mainly used in the textile industry, dyeing and finishing, for printing, mangle, pad, use a cloth guide rollers. Minute drive roller and driven roller two categories. Driving roller and driven roller used in conjunction. Capstan roller cover high rubber hardness, Shore A hardness of 98 to 100 degrees, passive roller cover rubber elasticity, low hardness, Shore A hardness is generally 70 to 85 degrees. Press uses include padding rollers, rolling water roller and guide roller of the points. Usually with NBR and other rubber and produced by compound. By zoning can be divided into: rolling cot, washing roller, rubber roller dye tube, the liquid rubber roller, rubber stamped calender rolls, pressed Cot. Cots and Metallurgy same basic printing Cots market share volatility is not. Printing rollers for industrial Cots most representative products, accelerating the pace of development in recent years. Accounted for 35% to 45% market share, the development momentum is very strong. Currently printing rollers as part of the domestic manufacturing enterprises supporting the production of rubber roller presses, a small amount of additional business for high-end printing presses equipped with rollers. One way to have two supply cooperation with printing press equipment manufacturers, printer manufacturers provide cots performance parameters required; the second is to work directly with the end-user printing companies for reprocessing old roll and provide a new roll. There are no fewer than 400 large and small around the rubber roller manufacturers, mostly for sale to retail mainly to provide services to their surrounding area printing companies. Overall most of our printing rollers manufacturing enterprises small, poor level of equipment, backward technology, the production of rubber roller products to medium and low based. Can only be used on the low-speed presses, life is not long. So the market share is not high, with large domestic enterprises, foreign enterprises or joint incorporation-owned enterprises can not compete. High-grade printing rollers although a small amount of production, but most of them are dependent on imported glue roll products, especially rubber rollers used on the import monopoly of imported products largely offset the higher its share. About 4--5 years ago, high-end printing presses Cots substantially from imports. With the increasing requirements of the domestic market, the current domestic printing equipment manufacturers also have to develop high-end printers. With the continuous development of China's printing industry and the introduction of increasing the number of high-end imports offset the demand for high-quality printing rollers is also growing. Plus the price of imported glue roller is more expensive, but the market is still strong demand diminished, for this situation, there is the ability of some domestic manufacturers of printing rollers have been targeting high-end imported equipment market, the introduction of foreign advanced technology, high-end printing start Cots R & D work. Large rubber roller manufacturers began producing alcohol dampening rollers, some companies developed and produced Cots even fill the domestic market. With economic development, a number of internationally renowned rubber roller manufacturers have to look at the Chinese, and started to invest and build factories in the country. It will manufacture high-grade rubber roller market impact. Some companies are not satisfied with domestic production and sales, but also to look to invest in foreign markets. Cots on foreign luxury market, domestic high-grade printing rollers began to place. Some products have been directly or indirectly exported to Japan, Germany, Italy, Britain, the United States, Russia and other countries. China's economy started relatively late in developed countries, overall quality of domestic printing rollers compared with foreign products, there is a big gap, so a smaller market share. Future domestic manufacture printing rollers should focus on increasing the variety, improve product quality and grade.
