Thin-wall part can not afford as much thermal induced residual stress as the conventional one does. An even cooling design becomes very important to control the shrinkage and warpage at an acceptable level.

For larger molded parts, material typically represents more than 50% of the part cost for a refrigerator crisper tray. In the case of a thin-wall small part, the press cost could be 90% of the cost of the part; material constitutes 6% and the mold only 4% of the cost of each part. Small thin-wall parts typically benefit from improved cooling more than thick parts.
