| This is a 2½ pound capacity drop box attached to a 12" x 12" x 12" test box mold. Triple wall moldings are a snap since this mold also has a manual fill port. Drop boxes are insulated to prevent early melting of the material inside and are discharged using compressed air through a ported arm. We have built drop boxes with capacities up to 65 pounds of 35 mesh polyethylene. | |
