Abstract
A mold system uses a pair of mold parts formed as continuous loops of resin extrusion, and the mold parts have generally dovetail-shaped side edge projections. Two continuous loops of flexible and springy retainer strips coated with a resin covering are formed in a general U shape in cross section and are clipped respectively over the side edge projections of the mold parts. The retainer strips are flexible enough to follow a curved path with the mold parts closed to hold a molded product, and the retainer strips allow the mold parts to be made of the most suitable material without having to snap tightly together without external assistance. Longer mold life can be achieved with the retaining force being provided by simple and easily replaceable retainer strips.
