The present invention relates to a method for producing a foam molded product, in which in a foaming step, at least a part of a burr is made to be an undercut that is caught in a movable mold portion when mold opening the movable mold portion, in a cross section obtained by cutting a foam intermediate on a plane orthogonal to a direction in which a boundary between a main body and a burr extends, a fragile portion is provided at the boundary such that at least a part of the burr located near the boundary is narrowed toward the boundary, and a foam intermediate is formed, and in a removal step, the fragile portion is broken and the burr is removed by pulling the burr with the movable mold portion.

A therapeutic device and a method of making a therapeutic device. The therapeutic device has a body portion having a first end, a second end, a first end portion, a second end portion, and an intermediate portion interposed between the first and second end portions. Extending inward into at least a portion of the body portion of the therapeutic device from at least a portion of the first end of the therapeutic device is a receiving portion. At least a portion of a surface defining the receiving portion has a shape needed to apply a suction force onto another object needed to secure at least a portion of the object within the receiving portion of the therapeutic device.

Systems and methods for casting solid propellants include a mandrel for forming geometric features in a perforation of a propellant grain. In various embodiments, the mandrel includes a frangible portion that is removed from the propellant grain after the propellant grain has cured around the mandrel. A second portion of the mandrel may be left behind in the propellant grain. The mandrel may include a support structured disposed in the through hole of the mandrel. The support structure may include a plurality of longitudinal channels for directed exhaust gasses through the mandrel upon ignition of the propellant grain.

The improved mold assembly for cultured marble molding is provided. The mold assembly can comprise a male mold portion and a female mold portion. The assembly can further comprise a molding tool. The molding tool can have a side wall having an upper curved s and a lower curved portion. The molding tool can be constructed from a flexible and/or soft material. The lower curved portion of the molding tool can be coated with a gel coat having a first color. The molding tool can facilitate molding of a countertop having a recessed bowl portion having a color different from a counter portion of the countertop.

A method of system of forming a biopolymer hydrogel structure includes a mold loaded with a cation. At least a portion of the surface of the mold is exposed to a solution comprising a gellable polymer such as alginate. An electric potential is applied to the mold so that the cation therein and the gellable polymer migrate via electrophoresis toward the surface portion, thereby interacting and forming a hydrogel structure adjacent to the surface portion.
