Pre-forming technology
Hot forging always results in producing a certain amount of excess material, or flash. Due to a higher deformation capacity of aluminum, more extensive flash formation occurs.
In view of the cost difference of aluminum material in relation to steel (approximately 2:1; 1 ton of steel at the amount of C= 500, and 1 ton of aluminum AlMgSi1 at C= 1,650), it is particularly important to keep the material excess as low as possible. Therefore Müller Weingarten has developed a process of aluminum cross-rolling (in 2001) and aluminum reducer rolling (in 2002).
Cross-rolling is a continuous forming process during which a cylindrical billet is formed on cylinder jackets between two tool segments operated continuously.
Reducer rolling is multistage forming achieved by partial pre-forming in different roll grooves discontinuously.

Pre-forming 技术热的锻件总导致导致某一相当数量剩余材料, 或闪光。由于铝更高的变形容量, 更加广泛的一刹那形成发生。由于铝材料成本偏差关于钢(大约2:1; 1 吨钢在数额C = 500, 和1 吨铝AlMgSi1 在C = 1,650), 它特别重要尽可能低保留物质剩余。所以M5uller Weingarten 开发了铝十字架辗压(2001) 并且铝还原剂辗压的过程(2002) 。十字架辗压是期间圆柱形宿营被形成在圆筒夹克在二工具段之间连续被管理的一个连续的形成的过程在。还原剂辗压是多级形成由部份pre-forming 不连续地达到用不同的卷凹线。
