Abstract: When manufacturing a foil-wrapped breast prosthesis with a filling consisting of a curable compound, the curing is performed after placing a filled prosthesis bag formed by two joined foil sheets in a mold cavity without closing the mold cavity and maintaining vacuum at least in the beginning of the curing, whereby especially an increased degree of freedom is obtained with respect to shaping the rear side of the prosthesis, so that this, among other things, can be provided with thin edge parts for obtaining good fitting to the body. To ease the mounting of the bag and the accurate positioning of this in the mold cavity, the latter is formed in a first mold part of a shaping tool, which furthermore comprises a tightening frame having a packing, which provides an unambiguously oriented tightening of the bag when this is placed in the mold cavity.

Liquid foam material is then injected in the mold and permitted to cure thereby forming a contoured seat cushion.

Abstract: In a method of manufacturing an in-the-ear hearing aid (25), a mould (23) is made of an ear canal for use as a moulding die for making a housing of the hearing aid. After the mould is made an auxiliary tool made up of a flexible tube (11) with a flange at one end is inserted into the ear canal into the proximity of the tympanic membrane of the ear. Subsequently, a curable material (19) is introduced into the ear canal. The material presses the flange against the tympanic membrane, which precludes the ingress of material between the flange and the tympanic membrane. After the material has cured the mould with the tube and the flange is removed from the ear canal. During removal of the mould the space between the tympanic membrane and the mould is in communication with the outer air via the tube, so that no partial vacuum is produced which otherwise might damage the tympanic membrane. The mould obtained is used as a moulding die for making a custom made in-the-ear hearing aid.

The hardened blank is proximally and distally freed of otoplastic shell material and is also proximally freed from the cap such that the die or a remaining part of the die can be easily and unproblematically removed in distal direction, so that the over-shell with the otoplastic shell material seated thereon remains as a finished otoplastic shell.

Abstract: A method and apparatus for growing squash, cucumbers and other fruits in desired shapes. The fruit, while growing on the plant, is enclosed within the internal cavity of an oversized mold having a cavity (inside) surface configured to form the desired details on the fruit.

The mold can be opened or removed after the fruit has conformed to its details, and the fruit is removed from the plant. The fruit can be eaten or, if dried, can provide a long-lasting sculptural item.

Abstract: A structural ice mold of the large, single use type, preferably made of FDA approved low density polyethylene plastic, is rotationally molded into a shape forming a hollow cavity on the inside thereof which defines the ice sculpture or figurine to be formed therein. In the improvement of the invention a narrow peripheral ridge or U-shape rib is extended vertically around the outside of the ice mold, preferably at the parting line of the permanent parent mold. The one-piece mold may be opened at the U-shape rib by cutting across the side of the rib at positions away from the surface of the ice figure formed in the mold, rather than by cutting perpendicularly through the mold surface and potentially into the ice figure therein. An additional improvement in ice molds resides in a hollow core formed in the base of the mold which allows for expansion of water in the mold when it changes phase into ice, thereby reducing stress and cracking in the finished ice form.
