SP260-WF60 - Sacma Warm Former (second generation)

This video shows the second generation of warm forming machines fully integrated. The application of a warm forming system to horizontal forging machines extends the possibility of making net-shape parts of more complex shapes and to work with special materials which could not be forged cold. In order to meet these new requirements in the industry, SACMA has developed special machines, incorporating induction heating units in the feeding areas. The typical temperature range of warm forming applications is between 400°C and 900°C. High frequency induction heating is obtained by means of special coils that can be fitted outside or inside the main frame of the machine, between the feed rolls and the cut-off quill. There is specific cooling of the coils and of the frame and the temperature of the wire is read by specific optical pyrometers. The WF application can then be completed with temperature control of the die box and of the coolant liquid.
