The company's leading products include large-scale fixed pitch propellers, adjustable pitch propeller blades and shells, energy-saving devices, vortex fins, and supporting products for ships such as shafts and rudder systems.

The company currently covers an area of 200000 square meters for production and operation, with a construction area of 24000 square meters for production workshops, including casting workshops, precision machining workshops, and rough machining workshops. The company's production and processing equipment is at a world-class level, and the melting equipment is equipped with the world's most advanced intermediate frequency induction furnace manufactured by Yingda Company in the United States. It has a melting capacity of pouring 200 tons of copper water at once.

The processing equipment mainly includes: 1. The eight axis five linkage CNC gantry milling machine imported from the German Coburg company, with a cost of 100 million yuan after installation. This machine tool is the most advanced processing equipment for box frame and curved surface products in the world at present. It is the largest, most accurate and most advanced one of the similar products exported to the Chinese Mainland by Germany's Wadrich Coburg Company. It has extreme processing capacity and represents the highest level of precision machining of heavy machinery parts in China (at present, this type of equipment has been banned from sale in China). It can produce a diameter of up to 12m A propeller with a maximum weight of 120 tons per finished product; 2. The 12.5 meter turning and milling composite CNC vertical lathe and Ø 200 CNC floor milling and boring machine purchased from a machine tool company in Beijing are both equipped with original German drawings from Coburg, and are at the world's leading level among similar equipment.

The company passed the ISO9001:2015 quality management system certification in 2022.
