The instant invention is related to a method for replicating an object. The method includes providing an object comprising an outer surface and a channel; applying dry tannin powder to the outer surface of the object wherein at least a portion of the dry tannin powder adheres to the outer surface as imaging tannin; and placing an aqueous solution of an iron salt in the channel wherein the iron salt diffuses through the object to convert said imaging tannin into a replica of the object.

A method for production of a tubular body applying the following steps: Pressureless application of at least one first curable plastic layer made of reactive polyurethane materials with a core via a rotational molding process, Curing the at least one plastic layer, Winding at least one reinforcement layer onto the at least one first plastic layer, Pressureless application of at least one second curable plastic layer, wherein the reinforcement layer is embedded without holes between the two plastic layers, and Removal of the core after completion of the body.

Because of this, the position of the reinforcement layer 7 can be individually established and it can be ensured that the reinforcement layer will not penetrate into the first plastic layer during winding after the curing of the first plastic layer.

A compressible decoy construction involves a thin rubber roto molded outer shell lined with a thicker layer of foam rubber. The interior of the decoy is hollow, thus allowing the decoy to be folded or compressed into a small mass such that when the compressive force is removed, the decoy returns to its full shape due to the memory of the foam rubber lining.

A method of forming an implant includes providing a preformed shell formed from at least one cured elastomeric layer. The shell includes an outer surface, an inner surface, and an opening for accessing an interior volume of the shell. The method further includes expanding the shell to an expanded state, in which the interior volume is greater than the interior volume of the shell at a time of forming the shell and forming an inner zone having at least one inner elastomeric layer on at least a portion of the inner surface of the shell, while the shell is in the expanded state, thereby forming a multi-zone shell. The method further includes reducing the interior volume of the multi-zone shell, thereby contracting the at least one inner elastomeric layer of the inner zone and causing texturing of the at least one inner elastomeric layer.

For manufacturing composite parts (1) having an inner hollow moulded body (2) with openings (3), which are accessible from outside, the moulded body is introduced into a moulding tool on the mould walls on which a shell layer (11) was applied. The hollow space between the moulded body (2) and the shell layer (11) is filled with a thermally insulating plastic foam (12) which is foamed in the moulding tool and bonds to the moulded body and the shell layer. After removal, a moulded body is provided, which has a qualitatively good surface formed by the shell layer. Such a composite part is preferably used for connecting thermally insulating pipes.

The invention provides a method of producing a solid material, and the method includes: applying a light coloring substance to at least one of an inner surface of a die bore, an upper end surface of a lower punch, and a lower end surface of an upper punch; filling a powdery material in the die bore; compression molding the powdery material filled in the die bore with use of the upper punch and the lower punch; and irradiating with light a molded product obtained by the compression molding to color the molded product.
