ABSTRACT:
A modular mold system for making molds in a range of incrementally different sizes is provided as is a method for using that system in the manufacture of containers. The mold system includes corner elements, edge angle elements and spacer elements which can be interlocked together through connecting means to form a mold for a container. The boundaries of each mold element are defined by straight lines meeting at right angles and each mold element has at least one common dimension with every other element. The mold system is particularly adapted for use in making fiberglass reinforced products such as insulated containers having an inner shell and an outer shell with insulation between the shells.
