A larger processing window
will account for the lot to lot changes between
materials, without having to make process
changes .3
Setting the Beginning Variables
• Injection Pressure = Maximum of machine
- Should not be pressure limited
• Injection Velocity = Maximum of machine
- This is for the injection velocity curve
starting point
- If flashing is an issue start slower and
then increase
• Injection Cut-Off Time = 15 seconds
- This is only a limiting factor, needs to
be above 10 seconds for velocity graph
• Hold Pressure = 0
- Need to get 95% full part with a hold
pressure of 0
• Hold Time = 10-15 seconds
- Need to ensure gate is frozen
• Screw Speed = 90% of Maximum
- Unless shear sensitive material, if shear
sensitive, set RPMs to optimum
• Cooling Time = 10–15 seconds
• Shot Size = 50% of calculated part volume
• Decompression = .25"
• Transfer Position = High enough to ensure
a cushion
- Cushion size does not matter but there
must be a cushion to keep a constant
pressure on the melt during hold time
- Typically 0.25" is sufficient
• Back Pressure = 800-1000 plastic pressure
- 100–150 hydraulic pressure
- Unless specified by material data sheet
Determining Shot Size
The shot size should be determined by
calculating the combined volume of the parts
and the runner system .
If
the material is shear-sensitive, consult the
material data sheet or processing guide for
instructions to set recovery time
• The cooling time should only be 1–2 seconds
longer than the screw recovery time, unless
dictated by dimensional stability or part
thickness
Minimize Clamp Pressure
This step is done to reduce the amount of energy
used by the machine
