| Balancing with Flow Leaders & Flow Deflectors... |
| Plastics flow leaders are local increases in the nominal wall thickness, whereas flow deflectors are local decreases in thickness. Many times a part cannot be balanced by gate placement alone. It can be useful to slightly change the wall thickness to enhance or retard the flow in a certain direction. |
