details DESIGN


Deep pockets, gussets and ribs can be placed at any orientation at the desired location.


• T e lost-foam process does not need cores to capture the interior features, providing design fl exibility and high dimensional accuracy for true positioning.


• Near-net shaped features eliminate the machining operation and extra stock.


Zero or negative draft features reduce unit weight.


• Reduced draft combined with gener- ous fi llet, radii and transitions for good metal fl ow results in overall weight and cost reduction.
