Operation
This mold requires no intervention on each shot. Just remove the part and hit cycle again to start the next part. There is a large pause after injection to let the part cool off in the mold to prevent warping. While waiting, clean the part just pulled out of the machine so there is no need for additional cleaning time.
The ejection system does not push the part completely out of the mold. You may have to use your hands to free by pushing it up. I have made a leveraging tool to help do this (see below).
Quality Checks
- Make sure the part is fully formed.
- Using a .166 drill installed in a holder make sure all of the 7 holes are free of any plastic oozing back into the cavity.
- Check that the part is flat and not warped.
