A formed article of a fiber-reinforced resin material is provided. The fiber-reinforced resin material is obtained by impregnating a plurality of stacked fiber layers with a resin. The formed article contains a first portion and a second portion formed to have a deep-drawn shape with respect to the first portion. The second portion contains a gradually changing portion with its thickness gradually changing, and the thickness of the gradually changing portion decreases with distance from the first portion.

Embossing method and apparatus

A method of embossing a crown cap comprises the steps of: detecting a pre-printed drawing on the bottom of the crown cap, varying the angular positioning of the crown cap so as to position the drawing according to a preset positioning, and impressing a raised/recessed pictogram on the bottom of the crown cap. The pre-printed drawing and the embossed pictogram will have a desired reciprocal position.

SPILL RESISTANT DISPOSABLE TRAVEL CUP LID
20180065333 · 2018-03-08 ·

A disposable drink-through dome lid for disposable drinking cups used in the sale of hot or cold beverages, the top of the lid elevated above the top of the beverage cup when in place. The lid's outer wall is elevated to form a drink ridge adapted to the user's lips for drinking through a generally oval-shaped drink-through orifice. Ideally, the drink-through orifice includes: a drink-through chamber having a drink flap capable of closing off a drink-through opening, thereby shielding against accidental spillage due to sloshing of the beverage while traveling; and a recessed orifice ridge on the interior side of the drink-through orifice, directs froth exiting the drink opening into a spill reservoir. A vent opening positioned near the lid's center and within a vent slot, collects and directs beverage exiting the vent into the spill reservoir.

20170050350 · 2017-02-23 ·

A method comprises the steps of: providing a cap-shaped body (2; 102), said body (2; 102) having a side wall (4) extending around an axis (Z) and a transverse wall (5; 105) arranged transversely to the axis (Z) for delimiting a concavity (7) of the body (2), the transverse wall (5; 105) having an inner face (8; 108) facing the concavity (7) and an outer face (9; 109) opposite the inner face (8; 108); placing a dose (43) of polymeric material on the outer face (9; 109) of the transverse wall (5; 105); compression moulding the dose (43) in contact with the outer face (9; 109), thereby obtaining a shaped element (3) from the dose (43), said shaped element (3) being attached to the transverse wall (5; 105).

Forming device and forming method

Provided is a forming device including: a lower die; an upper die for forming a laminated body along the surface shape of the lower die by pressing the laminated body against the lower die; a pushing force generating mechanism that generates pushing force for pressing the upper die against the lower die; and a control unit that controls the pushing force generating mechanism, the upper die has a plurality of forming members aligned in the longitudinal direction, the pushing force generating mechanism has a plurality of pushing force generating units connected to the plurality of forming members and configured to generate pushing force for pressing the forming members against the lower die, and the control unit controls the plurality of pushing force generating units so as to press a pair of forming members arranged adjacent in the longitudinal direction toward the lower die at different timings from each other.

Multi-stage pressing process for producing a molded part such as a bipolar plate from a highly filled thermosetting material

A process for producing a molded part from a highly filled thermosetting starting material including: introducing the starting material into a prepressing tool; producing a preform from the starting material, the starting material being brought to a prepressing temperature by the prepressing tool and being compressed with a prepressing force to form the preform; removing the preform from the prepressing tool and introducing the preform into a finish pressing tool; and producing a finished part from the preform, the preform being brought to a finish pressing temperature by the finish pressing tool and being compressed with a finish pressing force to form the finished part. Here, the prepressing temperature is lower than the finish pressing temperature and the finish pressing temperature is at least as high as an onset temperature of a curing reaction of the starting material.

METHOD OF PRODUCING SEPARATOR PLATES BY HOT COMPACTION

A method for producing a separator plate, where a malleable compound of thermo-plastic polymer and electro-conductive filler is provided for hot-compacting into a separator plate. The compound is inserted into a press-form, which is heated to a first predetermined temperature in a heating station, and only then inserted into a press for hot compaction between press blocks, which simultaneously during the compaction take up thermal energy for cooling the press-form and the sheet, that is resulting in the separator plate.
