Sorry Rick- This is the valve gated part. the center pc is the one that is having all the warp. I have tried sequencing them, different pack times, starting to fill this panel first and...
So again, we were able to convince the customer to switch to a talc reinforced material (TPO) on the seat back that I was having warp issues with. This will not always be a possibility, any tips for...
The parts are already warped as soon as the robot drops it in the cage.
I tried up to 45° difference and still nothing. I was not comfortable (nor was I at this point either) running any higher for production. This was just an effort to see if the warp could be changed...

This is the bin I had issues with. A change to 20% TF PP solved the issue.
I have adjusted the pack/Hold times and pressures. Cure time... I shaved 10.0s off and added 60.0s. Neither...
I have had two tools recently come my way that are slatted for 20% GFPP. Looked at Mold Flow, both show warp tendencies and both have been warped. More than MF said but in the areas. I have tried...
What is your recovery profile? I run Mucell on a daily basis for a load floor and do not see this issue. We have it on two machines. The screw and barrel should be set up for Mucell (and bought from...
I have done this when there is slipping issues with the check ring or wear in the barrel. it works well but the issue behind that is the fill rate must stay constant. Adjustments to heats, fill...
This part is way too over packed to even worry about the blush at the gate. Is that defect on a short shot? Try reducing initial fill speed, adding extruder delay or reducing recovery (screw...
Could be that you are timing out during injection. Check all heaters. Maybe take an actual "Melt Temp" reading of the material if you have the ability. Do you see fluctuations in fill time when all...
