Nantong Hongda Electro-mechanical Manufacturing Co., Ltd. is a high-tech enterprise founded in 2002. We have employed dozens of professors both foreign and domestic. And we devote ourselves to the development and research of high-efficiency foggers. Recently we cooperate with American companies in researching a new type of high-technology fogger. Our successful research and manufacture fill the blank of domestic high technology. We develop to reach the international level, so as to shorten the distance between domestic foggers and the international foggers. In recent years, the demand of plant prevention machines in domestic market has steadily increased. And plant prevention machinery industry grows rapidly. Series of foggers sell fast continuously. Meanwhile the security problem of the fake products and the safety accidents of fogger happened time to time. As statistics show, there are hundreds of thousands of people died and wounded because of runaway, give-off, drop and leakage of foggers. Serious damages have occurred. Thus central leaders paid much attention to the safety of foggers. And premier Wen Jiabao also said: we must be determined to take measures to change the undeveloped production and disordered situation. Our company applies advanced manufacturing techniques, enhances quality and cuts costs. We produced the first truck-mounted forger in China. We have models like truck-mounted, portable (side carrying), backpack straight pipes and backpack bend pipes.
