High stiffness plastic wall for molded plastic products

摘要

Plastic parts (20) are formed to have a relatively high wall stiffness by utilizing a pair of spaced plastic plates (22, 24). One of the plates (24) may be a simple plate. The other plate (22) has a plurality of ribs (28) extending from a base (26). The ribs are welded to the other plate. Use of the ribs provides a relatively high degree of stiffness to the final molded plastic part, for a relatively lightweight part.
