HALF SHELL
A method for producing a half shell for a hollow body includes applying a preheated plastics sheet to a first tool half that forms a die, and then pre-stretching the plastics sheet, at least in certain regions thereof, by blowing or suctioning away, at least certain sections of the plastics sheet from the first tool half. The plastics sheet is then suctioned or pressed, via pressure or negative pressure, onto the first tool half, at least in certain regions.
Method for producing hollow bodies from thermoplastic materials by using an at least three-part blow-molding tool and apparatus for carrying out the method
The invention relates to a method for producing hollow bodies from thermoplastic material by using an at least three-part blow-molding tool with at least two blow-mold halves (1a, 1b), which define a mold impression, have part-cavities (5a, 5b) and can be displaced toward one another and away from one another in the sense of an opening and closing movement, and also with at least one central tool (2), which is displaceable transversely in relation to the opening and closing movement of the blow-mold halves (1a, 1b), the method comprising the extruding or providing and arranging of at least two molten performs (7) of thermoplastic material in web form between the blow-mold halves (1a, 1b) in an opened receiving position, the bringing to bear of the preforms (7) in the part-cavities (5a, 5b) of the blow-mold halves (1a, 1b) and molding of them into shells (10) using sealing elements which are provided on the central tool and are extended from the central tool for the purpose of sealing off the part-cavities before or while the part-cavities are subjected to differential pressure; the joining of at least one insert (9) in at least one shell (10) by using the central tool (2) arranged between the blow-mold halves (1a, 1b) and the joining of the shells (10) to form the closed hollow body by closing the blow-mold halves (1a, 1b) while applying clamping force and, if appropriate, the final blow molding of the hollow body.

Thermoformable polymer thick film transparent conductor with haptic response and its use in capacitive switch circuits
This invention is directed to a polymer thick film transparent conductive composition with haptic response capability that may be used in applications where thermoforming of the base substrate occurs, e.g., as in capacitive switches. Polycarbonate substrates are often used as the substrate and the polymer thick film conductive composition may be used without any barrier layer. Depending on the specific design, the thermoformable transparent conductor may be below or on top of a thermoformable silver conductor. Thermoformable electric circuits benefit from the presence of an encapsulant layer over the dried polymer thick film conductive composition. The electrical circuit is subsequently subjected to an injection molding process.

METHOD OF MANUFACTURING SHAFT-SHAPE COMPOSITE MEMBER
To provide a method of manufacturing a shaft-shape composite member in which a bent section is suitably treated. A plurality of thermosetting fiber-reinforced resin materials made of a UD material is supplied to a bending section of a mold in a state of being aligned in parallel to an axial direction of a cavity to form a UD material layer. Subsequently, after forming a tubular member having the UD material layer by the metal mold, by thermally curing the tubular member, the shaft-shape composite member having the bent section can be obtained. When manufacturing the shaft-shape composite member, a cross-section orthogonal to the axial direction of each of the fiber-reinforced resin materials has a circular shape.

Modular thermoforming system
A thermoforming system and related methods for manufacturing thermoplastic parts, such as interior panels for aircraft, may include a roll-to-roll operation and a forming press having at least one selectively rotatable tool. The rotatable tool, which may include a mold and/or a die, may be multifaceted, such that different faces of the tool have different mold arrangements for different forming characteristics.
