110 planishing strokes per minute

Goldsky Titanium Industry Technology Co., located in the Chinese province of Hunan, ordered from Siempelkamp a forging press for titanium. Because of the tight temperature range which has to be kept during the forging of titanium, this press is especially challenging. 

With the new machine that has a press capacity of 40/45 MN Goldsky will forge rods, square bars, flat bars as well as tool blocks, flanges, washers and pins. These parts are primarily made of titanium but also contain tool and stainless steels. The investment in the new press was triggered by an increasing demand for high-strength and, at the same time, light-weight components for the aircraft industry.

Because of the tight temperature range which has to be kept when forging titanium, the Chinese customer made their buying decision depend upon the high forging frequency of the press. This high forging frequency not only results in shorter processing times but it also applies thermal energy to the workpiece. This, in turn, reduces the temperature drop of the workpiece during forging. As a result the forging can take place in a temperature range that is advantageous for the forming properties.  

Siempelkamp’s solution to this technological challenge is an optimized press design and an optimized control concept for the hydraulics and electrical engineering. 

Two forging manipulators working synchronously with the press are responsible for the product handling. This concept ensures that the customer can manufacture a versatile range of products.

The visualization of the process data during forging is carried out by Siempelkamp’s newly developed process control system PROD-IQ Metal, a system which incorporates the collection, interpretation, and evaluation of process data, as well as the preparation for product changeover and the maintenance of the machine. 

The Goldsky company is a new Chinese customer for Siempelkamp.

The supply of the press is scheduled for December 2009, the startup for January 2010.
