Disclosed is a method whereby a narrowed part similar to an actual lesioned blood vessel can be easily obtained. A mold (10) comprises first and second molded members (16, 17) having inner spaces (29, 40, 57) passing through in the axial direction and an axial member (18) detachably inserted through the individual inner spaces (29, 40, 57) of the individual molded members (16, 17). The molded members (16, 17) have tapered front parts (27, 27) respectively. In the state of facing the front ends (20) of the tapered front parts (27) to each other and thus forming a concave (12), the axial member (18) is attached. A first material (75) made of a mixed material comprising calcium carbonate or the like and silicone or the like is applied to the concave (12). A second material (76) such as silicone is applied to the entire outer periphery of the mold (10). After hardening the materials (75, 76), the mold (10) is withdrawn by detaching the axial member (18) and dividing the concave (12). Thus, a simulated blood vessel (78) having a simulated narrowed part of the blood vessel caused by calcification can be obtained.

A stackable mold for making block ice is disclosed. The bottom edges of the sidewall of the mold have stacking lips and the top edges of the sidewall have stacking ledges. The stacking ledges of a lower mold mate with the stacking lips of an upper mold, thereby allowing multiple molds to be stacked on top of one another. Guide lips along the sidewalls of the mold prevent slipping and shifting of the stacked molds. The tapered property of the molds creates space between the bottom of an upper mold and the top of a lower mold to allow airflow through the lower mold. A reinforcing lip extends along the top of the long sides for reinforcement.

A mold is integrally formed from a flexible material that is suitable for baking or molding food products, such as food grade silicone. In one example, the mold includes a rim at the top and a wall extending between the rim and a base at the bottom. The wall is sufficiently thick that the pan can support its own weight while holding a food item. The mold may include an interior or exterior relief pattern that is imparted onto the food item. In some forms, an upper portion of the mold is relatively smooth and more flexible than a lower portion having a relief pattern. An internal U-shaped stiffening element helps to prevent the mold from collapsing and improves handling of the mold.

The article and corresponding method include a casting fixture for a part of a skin formulation applicator which is otherwise difficult to cast. The casting fixture includes a central cup section and two opposing tear-away sections. A rigid base portion of an applicator tip assembly is mounted into an upper rim of the cup section and liquid silicone material is poured into the volume defined in the cup section portion beneath the base portion. The silicone cures and bonds to extending elements from the base portion, providing a firm connection between the cast tip portion and the base portion. When the combined part is ready for use, the tear-away sections are removed by the user, which results in an easy ejection of the part, which can then be installed by the user in the formulation applicator.
