PARA Rib Plate Edge Effect
Sorun Belirtisi
In ribbed PARA products, the ribs push the base plate to deform; fibers at the rib upper edge are strongly oriented, and flatness is out of tolerance.
Neden Analizi
Flow in the rib produces fiber orientation at an angle to the base plate; the relative thickness of rib and base plate determines the orientation difference; the most typical influence of Ixef PARA is the formation of a strongly oriented fiber layer at the rib upper edge, with shrinkage in the flow direction almost zero, and the rib top pushes the part out of plane.
Çözüm
①Design rib thickness at 50~60% of the base plate; ②Optimize rib position and direction; ③Local thickness adjustment to guide flow; ④Warpage simulation to verify rib influence.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
The edge effect of PARA rib plate design is a material characteristic; thickness ratio and position are design variables; simulation analysis predicts deformation in advance.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
