Recently, Dalian Marine Diesel Engine Co., Ltd. received the utility model patent certificate issued by the State Intellectual Property Office. The large-scale low-speed marine diesel engine disc cast steel coupling and the large low-speed marine diesel engine frame guide skateboard milling edge independently researched and developed by the company's technicians. Seven marine mainframe processing technologies, such as mobile devices and diesel engine warm-up and test bench test equipment, won the national utility model patent certificate.
In recent years, in the context of the continued sluggish world shipping market and increasingly fierce competition, the company attaches great importance to product quality and increases investment in R&D of host processing technology. After the company's technical staff persisted in research and development and summary, a series of advanced marine processing technology was formed, and the national patent was successfully applied.
