Processing requires a knowledge of how melt flow responds during the various stages of
part fill. The more complicated the part design is, the more intricate the velocity
stages need to be for best application of melt flow. The following is a technique for
developing staged velocities...while helping the processor to determine the precise
melt flow of plastic as it travels through the runner and cavity and knits at end of
fill.

Set up your process with 4 to 6 stages of velocity, with the positions being equal
lengths (ex: 4 stages at 2.00 inches would be as follows:

Position	Speed(Inches p/second)
2.00	2.50
1.50	2.50
1.00	2.50
0.50	2.50

This is a typical velocity set up. You are now ready to profile. The procedure is
to set all speeds at each position to 0, gradually adding speed back to each position
to cause the flow of plastic at each stage of position. The examples below
illistrate the method described:

Position	Speed(Inches p/second)
2.00	2.50
1.50	0
1.00	0
0.50	0

Position	Speed(Inches p/second)
2.00	2.50
1.50	2.50
1.00	0
0.50	0

Position	Speed(Inches p/second)
2.00	2.50
1.50	2.50
1.00	2.50
0.50	0

You can now view the melt flow orientation based on the short shots that
were produced by "stalling out" at each individual stage of velocity position
This will allow you to make adjustments according to part configurations your
speeds and positions based on the makeup of plastic flow. You can add additional stages
of velocity for profiling around details in the tool and adjust speeds in accordance
to speed-related defects.
