A controller of a rotary compression-molding machine is configured to rotate a turret including a table including a die bore, and punch retaining portions vertically slidably retaining punches disposed above and below the die bore along with the punches, and to fill the die bore with a powdery material from a filling device disposed just above the table, to compress the powdery material filled in the die bore with the punches and to obtain a molded product. The controller is configured to adjust rotational speed of the turret and the punches to allow the powdery material in a feed pipe, directly connected with the filling device and configured to feed the filling device with the powdery material, to have a level of an upper surface kept within a constant target range.

Methods and structures are disclosed. An example method includes: rotating a tubular mandrel about a longitudinal axis of the tubular mandrel; depositing a composite material on an inner surface of the tubular mandrel to form a composite tubular member on the inner surface of the tubular mandrel; inserting and expanding an inner expandable mandrel within the composite tubular member to cause the inner expandable mandrel to press the composite tubular member against the inner surface of the tubular mandrel; curing the composite tubular member; removing the inner expandable mandrel; placing a frame within the composite tubular member; and removing the tubular mandrel so as to obtain the composite tubular member with the frame placed therein.

Systems and methods of providing a composite material that is bendable but substantially resists stretching under tension. One embodiment may take the form of a composite material formed by over-molding a woven glass fiber with silicone. The woven glass fiber may be rolled out with a silicon polymer melted into the woven fabric as the rolling process continues. The composite of the two materials may provide a material that bends easily but does not substantially stretch.

A method for applying a sealant to the surface of an object includes forming an annular dose of synthetic plasticised material supplied from an extruder, depositing the dose on the surface of object and compression forming the dose to form a seal. The extruder includes an annular outlet which is opened and closed to deposit successive doses. Each dose that exits the annular outlet is separated from a supply of plasticized material in the extruder.

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.

A mold is provided for forming caps for closing containers by compression molding doses of plastic material, where a bottom wall of the cap, or at least one portion of the bottom wall is very thin. The mold includes two half-molds axially movable towards each other which assume an end closed position without a dose. A tubular element is slidable around the second half-mold and partially defines the cavity. The tubular element contacts an axial abutment of the first half-mold at one side and an axial end stop of the second half-mold at the other side to prevent hard contact between the half-molds.
