Donghai Group has been deeply cultivating the water meter industry for more than 40 years. From the 1970s, it made the movement of water meters and water meters to high-precision, large-caliber water meter production. From the 1990s, it developed the first-generation national-level key new products to smart water meters, With the development of water meter intelligent production lines, Donghai Group has been focusing on the water meter business.
With the arrival of the intelligent era, the manufacturing industry has also ushered in a transformation and upgrading. Intelligent production lines can effectively improve quality, production efficiency, save man-hours, and reduce labor costs. It is the future direction of the development of automated processing lines.
The main research contents of the project developed by Donghai Group are: automatic assembly of water meter impellers, automatic assembly of water meter movements, and meter flow detection devices. The research and development cycle is two years. Up till now, three utility model patents have been obtained and three invention patents have been granted. At that time, one industrial production application line will be established, and it is expected that a single production line with “machine substitution†of 12 to 15 people will greatly save costs.
