forward extrusion flow: [Q.sub.1] = [U.sub.1][H.sub.1]W, (3)
This means that at small-gap widths (h), the lateral extrusion stops at a certain point, and the forward extrusion is predominant during the process.

. A billet of diameter [D.sub.0] is extruded through a die of diameter [D.sub.1].
Stable Micro Systems' forward extrusion
cell measures the compression force required for a piston disc to penetrate the yoghurt and extrude it through an outlet in the base of a sample container.
To evaluate the performance of the rezoning algorithm, we have used the newzoner to analyze a forward extrusion process.
This forward extrusion analysis illustrates the increased ability of LLNL's NIKE2D code to simulate severe strain in ductile metals.
The usual forming stages are: reducing, forward extrusion, backward extrusion, upset, and trimming and piercing.
For example, if the simultaneous forward and backward extrusions do not go well in the third stage, the forward extrusion can be left in the third stage, and the backward extrusion can be done in the fourth stage.
