X2100-001-129 flow analysis reported2007/12/09Kevin,長盛科技股份有限公司Advanced Connection Technology Inc.,Problem definition,As early as in design stage use Moldflow gains the biggest benefit。In advance excavates the question spot which start the mold possibly exists。,End product contour and meat thick analysis,May see the meat thick difference by on chart to be enormous，Thickest probably is 0.45mm，Smallest is 0.16mm，Projects the formation to be able because the synaeresis creates the distortion and the warp possibly can be extremely serious。,Runner size disposition,Material nature correlation data,By models the materials storehouse search result to be possible to see，this material includes 30%GF therefore time analysis should pay attention to the Bolivian filament to match tropism。,Material properties,Viscosity vs. shear rate diagram,P-V-T diagram,Analysis forming condition,Fill time:0.1sec。Melt temperature:360 。Mold temperature:63 。Velocity/pressure switch-over:volume 100 %。Packing pressure time:2 sec。Mold Open time:5 sec。Cycle time:8 scc。Plastic:Zenite 6130LX BK010。,Fill time 1,Fill time 2,Temperature at flow front,May see the temperature distribution by on chart also to calculate the average。,Volumetric shrinkage,May know the volume contraction unusual average by on chart。,Warp distortion chart,May see the end product by on chart four angle point of descent is the contraction quite serious region，Also is leaves a quite far region to need to pay attention guarantees presses the time。,Air traps,May see this end product package of wind position by on chart in the backfill terminal，Therefore needs to pay attention to the exhaust。,Weld lines,May see the junction line position by on chart all to appear in the mobile terminal，pays attention to in these positions the intensity。,Conclusion,Must pay attention to the backfill terminal end product the intensity and the exhaust，solves the weld line and air traps the question，wild line easy to create on the end product the intensity to be weak easily to break，air traps easy to create the end product to shoot short，above question all needs to overcome。,
