Bellows forming machine: horizontal structure, chain drive design, with open water cooling system and vacuum forming system, greatly increasing the production rate. Online flaring function reduces investment costs and improve productivity. Module is running up and down simultaneously with a mechanical drive with advanced automatic lubrication system to ensure accurate running accuracy to ensure the quality and stability of the pipe. Bellows modules: special aluminum alloy material through precision casting corrugated molding module, with high precision and strength and excellent heat dissipation. Plastic Machinery Co., Ltd. Qingdao with three double-wall corrugated pipe production JDPE equipment at home and abroad to fill vacancies in Qingdao, double-wall corrugated pipe production line is the pipe series forward in a new field. Market potential analysis drainage is indispensable modernization of municipal infrastructure construction, compared with developed countries, China's municipal drainage level is very backward, our country is facing a historic opportunity to invest heavily in the construction of drainage network. China is a serious shortage of water resources in the country, less than 2400 cubic meters of water per capita, for a quarter of the world's per capita water. In many cities and regions in China can ensure the water supply of residents has become the primary problem facing the country less than 668 cities in more than 400 water supply. Important cause of the water crisis is to be no control of water, no drainage treatment of contaminated, such as pp double wall corrugated pipe production line, China's seven major rivers flowing through the river in 15 major cities, there are 13 river water serious pollution. Water pollution is also directly harm to all aspects of economic life and health of the people. Now, the whole country are calling for the protection of water resources, water pollution. In such a situation, plastic double-wall corrugated pipe production line, drainage infrastructure around the project has become a hot double-wall corrugated pipe production line, in the drainage pipe network engineering platoon is part of its core. Therefore, we predict that in the next two years, China will enter the construction of drainage network of climax, for plastic pipes buried created unprecedented opportunities for development. pp double wall corrugated pipe production line, with three presses (certified), double-wall corrugated pipe production line offers the same three Plastic Machinery Co., Ltd. from Qingdao. Plastic Machinery Co., Ltd. Qingdao with three (www.tongsansuji.com) is Qingdao, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the same three presses leadership with the staff warmly welcome all inquiries to discuss, with three presses to create a better future.
