Since 2010, an investment in tyres has rapidly spread throughout the country, and the prevailing situation is beyond expectation. According to incomplete statistics, there are as many as 40 new tire projects, and the total number of steel tires is as low as 600,000 units, and as many as tens of millions; the number of passenger tires is as low as 3 million units, and as many as 15 million units. More than demand. The reporter’s call for this phenomenon does not require the attention of the relevant departments and industries. Relevant experts also remind tire companies to rationally invest and reduce risks.
Reporters learned that Shandong Guangsu, known as the “tire nest,†has recently launched a climax to the construction of all-steel and semi-steel radial tire projects. The number of projects reached more than 10, and the scale of construction of radial tire projects reached 50 million sets. It is expected that production capacity will be formed in 2010-2011. Among them, Shandong Jinyu plans to expand the scale of all-steel tires to 3 million sets/year, and semi-steel tires to 15 million sets/year; Shandong Wanda has just started 15 million sets/years of semi-steel radial tires; Shandong Deruibao Tires Co., Ltd. has a total investment of 2.3 billion yuan to build a 6 million sets/year all-steel radial tire project; Shandong Watson Rubber Co., Ltd. has a total investment of 7.5 billion yuan in 3.5 million sets/year load-bearing all-steel tire project, which will be completed in three phases; Shandong Xingyuan The company has now started expansion of 2.5 million sets/year of all-steel tire projects... In addition, what's surprising is that non-tire manufacturers such as Haoyu Materials Group Co., Ltd. and Shandong Huatai Group have also taken a look at this area and are entering It is expected that the scale will reach 2 million units/year.
There are also more than 10 radial tire projects in Shandong outside the vast area. Shandong Delta Group plans to add 1.5 million sets of all steel tire production capacity; Shandong Linglong Co., Ltd. will start 12 million sets/year half-steel tire projects, and plans to increase its annual tire production capacity to 30 million sets/year in recent years; Hong Kong Yongyu Group Investment The Wendeng Nanhai Full Steel Tire Project is planned to have a construction scale of 12 million units/year and a sales income of 20 billion yuan; Huanghai Rubber Company will start a 5 million-unit/year semi-steel tire technical transformation project with a total investment of 500 million yuan; Qingdao Sen Unicorn Tire The company plans to build 162.5 million sets of semi-steel and all-steel radial tire projects, including 12 million sets of semi-steel high-performance radial tires, 4 million sets of all-steel radial truck tires, and 250,000 sets of engineering radial tires. /year.
“Not only that, but dozens of small-scale biased tire enterprises in Shandong, Gaomi and Pingdu, etc. are adopting an easy way to produce radial tires in the current sluggish tire market, and their product quality is even more worrying.†According to industry sources.
According to the reporter's understanding, investment in tire companies outside of Shandong Province is also spreading. Hangzhou Zhongce Rubber Co., Ltd. expanded production of 1 million sets of all-steel radial truck tires, launched Xiasha Base's new 13.8 million sets of semi-annual steel tire projects, and Shanghai Shuangqin Co., Ltd. expanded 600,000 sets of full-year steel tires in Albuquerque. , Chongqing has expanded production of 500,000 sets/year of steel tyres in Chongqing base; South China Tire & Rubber Co., Ltd. has established 300,000 sets/year of all steel tyres in Conghua, and is expected to have production capacity by the end of 2010; Guizhou Tire Co., Ltd. has completed 700,000 sets/year in recent days. The bidding for all-steel tyres is expected to be put into production in the first quarter of 2011; Henan Fengshen Co., Ltd. will start 5 million sets of steel tires per year; Shaanxi Yanchang Group plans to invest a total of 4.8 billion yuan to build 20 million sets of radial tires per year, which is now 1.2 million sets. / Full-steel tire project was completed in July; Zhengxin Tire Co., Ltd. plans to build a 10 million-unit/year radial tire project in Longevity with a total investment of US$1 billion. After completion, it will form 8 million sets/year of semi-steel radial tires and 2 million sets of tires. / Annual capacity of all-steel tires, with an annual production value of 9 billion yuan; and Haida Group, China National Chemical Industry Rubber Guilin Co., Ltd., Wuhan Aolise Tire Company, Henan Friends Tire Co., Ltd., Jiangxi Tailun Rubber & Plastics Co., Ltd. And other tire companies across the country have also started the tire program.
When the reporter was investigating and interviewing the reasons for launching tire projects across the country, Shen Jinrong, chairman of Hangzhou Zhongce Rubber Co., Ltd., said that at the beginning of 2010, the market generally predicted that the world economy will continue to show signs of recovery. Therefore, the tire market is in a state of restocking. . In this process, manufacturers will get a wrong signal that the market prospects are better. Therefore, most manufacturers take it for granted to accelerate production and expand production capacity. Concentrated, large-scale, and rapid construction of tire expansion projects will severely exacerbate the fierce and disorderly competition in the tire industry, and the risk of over-expansion is beginning to appear. According to statistics from the China Rubber Industry Association Tire Branch, from January to May 2010, the inventory of 43 major tire companies in China increased by 23% year-on-year, and most of the tyre factories were also surrounded by tires. In June, the price of tires generally fell by about 15% compared with the highest peak, and many companies had no choice but to start restricting production.
In view of the current tire investment in China, Gu Hongzhen, honorary president of China Rubber Industry Association, is worried. He metaphorically stated that the engineering giant tires in 2008 had caused a serious excess of engineering giant tires in China. The majority of engineering giant tire production lines were shut down at the time of production. However, the investment in tire investment in 2010 has exceeded the heat of the project tires in the year. This is a serious overdraft in the future of China's tire industry, which is extremely unfavorable to the development of the industry. It is hoped that tire companies will invest rationally and maintain the healthy development of the industry.
