Now conveyor manufacturers constantly changing institutional structures, the original state-owned enterprises accounted for 90%. In recent years, in response to national policy, the current private enterprises, collective enterprises accounted for 90%, there are three joint ventures, while only six state-owned enterprises. Reduced staff by the original enterprise workers less than 50%, the company's capital structure adjustment situation is still relatively good, the industry most companies with national management policies and good market opportunity has completed the recapitalization of work, capital structure more reasonable. In order to compete for market share, most emphasis on the sales and marketing staff of the team, while ignoring the power of technology to enhance and expand. As far as I understand it, most business leaders attach great importance to technical selling much more than that. As a product, the market is important, but seriously out technical R & D and innovation, product quality is not good, even if the market is bigger, is Wang Wei. Quality problems occur frequently in the coal mine, eventually occupying the market can not, according to incomplete statistics, in recent years, caused by the conveyor belt a steady increase in coal mine accidents, such as broken belt, unglued, deviation, etc., although there is no harm to people But seriously affected the coal mine production safety. And even some manufacturers, take the plastic surface rubber surface conveyor belt pretending to reap profits, these opportunistic, substitution of coal mine production safety means to leave a very big risk. In addition, some conveyor belt manufacturer in the whole flame retardant conveyor belt mass production, they also deliberately reduced retardant conveyor belt cover thickness, resulting in fire-retardant coating conveyor belt scrapped soon be worn cause, serious impact flame retardant conveyor belt service life, which directly affect the production of coal and interests. In recent years, coal users and conveyor belt manufacturers of quality problems are more and more, from 2002 to August this year, since more than two years, and the amount of handling the accident 10 years ago was essentially flat compared to the total amount, indicating that as a result of lower prices and quality of instability caused by coal mine accidents more and more problems. According to mine user research, because of the price, product quality is uneven, there is poor performance and short life problems, which have caused belt manufacturer's attention.
