Abstract
The paper develops a novel method to explore a suitable scanning installation to reduce deformation effect of foam cups under different moulding conditions, and proposes a quantitative assessment index for the geometric shape of foam cups via non-contact three-dimensional scanning. Two kinds of foams with different performance behaviour were selected for moulding test. Depending on the Box-Behnken design, a total of 12 foam cups in size 34B, 36C and 36DD for each type of foam material were scanned in the bird-view and upward-view positions for comparative purposes. Through a two tailed paired t-test and Pearson's correlation testing results, the most effective foam deformation index was confirmed firstly to assess the quality of the foam cups. The result shows that the deformation between moulded cup and its plastic shot scanned in the bird-view position is consistently less than that in the upward-view position. The amount of dwell time significantly affects the deformation for the two types of foam cups.
