Description
Large titanium rings are manufactured by the large grinding ring machine, small titanium rings can be achieved by forging machine. As a company with more than 20 years of production experience, we have a series of rigorous forging process and operation manual, including the heating steps, heating time and heat preservation time. The 35MN and 16MN rapid forging machine guaranteed the multiple forging in the suitable temperature range, and changed the internal physical structure of titanium rings. Greatly improved the quality of our products.
In addition to titanium ring, we also provide the production of titanium disc, titanium block etc.

Application
Used in the production of flange ring and ocean engineering structures
