A dry adhesive and a method of forming a dry adhesive. The method includes forming an opening through an etch layer and to a barrier layer, expanding the opening in the etch layer at the barrier layer, filling the opening with a material, removing the barrier layer from the material in the opening, and removing the etch layer from the material in the opening.

A molding system and method, allowing for the repeated use of the same molding insert for purposes of elaborate objects molding is described. The proposed method allows for multiple moldings of intricate shapes and curvatures improving the mass production of the jewelry moldings. During the process, the raw molding material is squeezed through the narrow opening inside the mold form under pressure. As the molding material enters the mold form, it is coated with a coating fluid. After the curing, the molding material could be easily removed through a narrow cavity opening, promptly reassembling back to the shape of the insert for continuous use in the next steps of the molding procedure.

Mould for making a support element for the human body, such as a bicycle saddle or a motorcycle saddle, wherein the mould includes a first component or matrix, which it is provided with a cavity open at the top, and at least one second component or false-male, in which the second component or false-male has a through opening, the cavity of the first component or matrix and the through opening of the second component or false-male determine a cavity, which has a conformation in use matching the conformation and/or the bulk and/o to the outer surface of the support element for the human body or the saddle; method for obtaining the support element for the human body and support element for the human body.

The present invention relates to a method for producing a negative skin and a tool. Such a tool can be used, for example, in the automotive industry.

The present invention provides a die assembly for molding a resin-made insert having a sleeve that is inserted into an intake port of an internal combustion engine. Each sleeve has one inlet and two outlets. The die assembly includes an inner die and an outer die. The inner die includes an inlet side part and an outlet side part. The inlet side part and the outlet side part mold an inner peripheral surface of the sleeve in an assembled state, and are removed in mutually opposite directions. By means of this assembly, a sleeve having a complicated structure and shape can be molded easily.

Fluid transfer assemblies for transferring fluid into or out of a single vessel and distributing the fluid to multiple other vessels are provided. The fluid transfer assemblies are customizable, substantially aseptic, and single-use. The fluid transfer assemblies may be manufactured by solidifying polymeric materials to form a body around a mandrel with protrusions engaged to fluid conduits and leaving recesses in the solidified polymeric material to stretch the resultant body and remove the mandrel with protrusions. The resultant fluid transfer assembly may be surrounded by a rigid housing and valves may be engaged with the conduits and/or body to control the fluid flow within the fluid transfer assembly.
