Claims
- 1. A test mold assembly for evaluating the surface deformation tendency of reactive plastic formulations to voids therein, said test mold assembly comprising:
- a mold having a rectilinear bottom and spaced pairs of side walls joined to said rectilinear bottom for forming a mold cavity to receive foam precursors;
- a plurality of test rods extending across said mold cavity between one of said pairs of side walls;
- means for removably supporting said test rods within said one of said pairs of side walls for separation from said mold cavity without removing molded material from said mold cavity;
- said test rods having a constant circular cross-section throughout the full length thereof; said test rods each having a different diameter outer surface with a top and a bottom line segment;
- said different diameter outer surfaces each having said bottom line segment located in a common plane which is inclined with respect to said bottom in a first axial direction thereof;
- each of said different diameter outer surfaces having said top line segment thereof located in a common plane which is inclined with respect to said bottom in a second direction different from said first direction thereof;
- said test rods producing a plurality of longitudinal holes of varying diameter within molded material in said mold cavity which holes vary in depth below the molded material between both said first and second pairs of side walls.
