SECURITY GUARDS COSTS

Security Plastics Inc. of Miami Lakes, Fla., has begun molding surface-mount technology electronic components made of DuPont Co.'s Zenite liquid crystal polymer resin in its Hetero-Cavity custom injection molding system. The system uses small, quick-change tools mounted in a custom mold base. Several customers' parts can be run in one base using a common material, thus sharing overhead costs.
