Deflection – All direction
Deflection – X direction
Deflection of X direction is balance, cause warp is little.
Deflection – Y direction
Deflection of Y direction is balance, cause warp is little.
Deflection – Z direction
S u m m a r y
The results
The flow status is balance, the injection and packing pressure is no
rmal.
ing of packing.
Deflection of X&Y direction is balance, cause warp is little. Defle
ction of Z direction is imbalance, possible cause warp.
