* Chemical machinery has become a climate with hydraulic machinery

“At present, the superiority of hydraulic vulcanizing presses has been widely recognized by tire companies in China, especially for high-grade radial tires that tend to use hydraulic vulcanizing machines. If we say that the use of mechanical vulcanization machines in China since the 1950s has replaced the vulcanization Tank is the first leap in tire vulcanization, then the hydraulic vulcanizing machine is the second leap in tire vulcanization instead of mechanical vulcanization machine.” Zhou Baodi, director of the Rubber Machinery Professional Committee of China National Chemical Equipment Association, said in an interview with reporters recently.

The development of hydraulic vulcanizing presses in China began in the late 1960s. During the national “8th Five-Year Plan” period, hydraulic vulcanizers were included in the “One-stop key equipment for radial tires” project. Many rubber machine manufacturers are optimistic about this “dragon”. The potential to develop hydraulic vulcanizers one after another. At that time, there were five or six manufacturers involved in the study. However, due to the fact that China's tire industry did not yet form a large-scale climate using hydraulic vulcanizing machines, tire companies did not have direct experience in using hydraulic pressure vulcanizers, and their domestic hydraulic components did not In the following ten years, no mass production was formed.

With the development of China's automobile industry and tire industry, higher and higher requirements have been placed on the uniformity of tires, and the working accuracy of the vulcanizing press has been paid more and more attention by people. The superiority of the hydraulic vulcanizing press has been fully demonstrated. At present, the proportion of hydraulic vulcanizing presses used by tires and rubber machinery companies has gradually increased and it has entered the stage of rapid industrialization.

“At the end of 2010, the proportion of hydraulic vulcanizing presses in China's tire factories was still less than 10%, but the situation has changed a lot. The superiority of hydraulic vulcanizing presses has been widely recognized by tire companies, especially in high grades. The trend of radial tires tending to use hydraulic vulcanizers is obvious, and it is estimated that the proportion of hydraulic vulcanizing machines used in the new half-steel radial tires project will reach 50%, and the proportion of hydraulic vulcanizing machines will be used in the new all-steel radial tires project. %the above". Zhou Baodi said, “The hydraulic vulcanizing machine is developed on the basis of a mechanical vulcanizing machine. It overcomes the inherent weakness of the mechanical vulcanizing machine and absorbs the advantages of the mechanical vulcanizing machine. The precision and automation are high, and the vulcanized tire is even. Well, it is suitable for the vulcanization of radial tires, especially high-grade radial tires. It has become an undisputed development trend to replace mechanical vulcanization machines." For years, Liu Fuwen, deputy chief engineer of the hydraulic vulcanizing machine Guilin Rubber Machinery Plant, also stated that the promotion of the hydraulic vulcanizing machine has become very easy now. Basically, tire companies have voluntarily required hydraulic vulcanizing machines.

According to Zhu Dawei, deputy general manager of Hangzhou Zhongce Rubber Co., Ltd., the company's semi-steel tires are mainly positioned as high-grade tires, and vulcanization is mainly used for hydraulic vulcanizing machines. The production of tires from the use of effect, good balance. Of the 13.8 million semi-steel tire projects just on the site, more than 200 vulcanizers all use hydraulic vulcanizers. The next 13.8 million semi-steel projects will continue to use hydraulic vulcanizers.

Hangzhou Zhongce has a wind vane effect for the selection of equipment. Shandong Vanda, Shandong Shengtai, Shandong Jinyu, Zhaoqing Hongtu, Henan Fengshen, Chaoyang Langma, Guizhou Tire, Shanghai Double Money and other projects follow most or all of the hydraulic vulcanizing machines. The boom of hydraulic vulcanizing presses in our country has risen in China. Jinyu Jin, general manager of Shandong told reporters that the company's last half-steel tire project vulcanizing machine used half of the mechanical half hydraulic type, the next project will use more than 200 hydraulic presses. Among foreign tire companies, the use of hydraulic vulcanizing machines has a higher proportion. Goody Dalian, Michelin Shenyang, Dongyang Zhangjiagang, Sumitomo Changsha, and Hantai Chongqing have all adopted hydraulic vulcanizers.

Zhou Baodi said, "I believe the hydraulic vulcanization opportunity will become a new economic growth point for China's rubber machinery industry in the near future." Overall, it is an excellent opportunity for the industrialization of hydraulic vulcanizing machines. First, tire companies, especially semi-steel tires, have changed their preference from mechanical to hydraulic in the past, which has created huge demand for hydraulic vulcanizing presses. Second, China has mastered the technology and principles of hydraulic vulcanizing presses. Currently, hydraulic vulcanizing presses have been developed independently. Ability to form an industrialization capability; Third, the key components of hydraulic vulcanizing presses such as hydraulic stations, fuel tanks, etc. have been localized, the procurement cost is lower, the sealing is better, and the delivery cycle is shorter, providing hydraulic vulcanizing machine industrialization Guaranteed.

A large number of hydraulic vulcanizer manufacturers have emerged in China one after another. The production capacity of hydraulic vulcanizing machines has rapidly increased. Traditional vulcanizing machine manufacturers in the production of mechanical vulcanizing machine at the same time, R & D focus shifted to the hydraulic vulcanizing machine, such as Guilin rubber machine, Yiyang rubber machine, etc.; some manufacturers directly from the hydraulic vulcanizing machine into the vulcanizer market, the market expanded very quickly , such as the Guangdong giant wheel, soft control shares, Beidai technology. Guangdong Kelun Mold Co., Ltd. produced nearly 200 hydraulic vulcanizers last year. There are now more than 200 orders for hydraulic vulcanizers, and production is in short supply. The soft control shares also have orders for nearly 200 hydraulic vulcanizing machines, of which more than a dozen units are exported to Indian JK Corporation. Shandong Wanda hydraulic vulcanizing machine tenders, up to 12 participating companies, it can be seen many hydraulic vulcanizing machine manufacturers. It is estimated that there are nearly 20 hydraulic vulcanizer manufacturers in China and the annual production capacity is over 1,000.
