An apparatus for manufacturing a pouch includes a die in which a pair of forming grooves are formed with a partition wall therebetween in a top surface thereof; and a pair of punches disposed above the die configured to form a pair of accommodation parts in a pouch film while being respectively inserted into the pair of forming grooves in a state of pressing the pouch film, wherein a pressing surface of each of the punches, which is configured to press the pouch film, has an inclined angle that is inclined upward from one end thereof disposed at a side of the partition wall toward an opposite end thereof.

A deep-drawing packaging machine that includes a sealing station and a method for changing the sealing frame together with the sealing plate at the sealing station. The sealing station includes a sealing plate and a sealing frame. The sealing plate may be releasably coupled to an upper sealing tool part, and the sealing frame may be slidably removable at a lower sealing tool part. The sealing frame may be slidable on rails. The sealing frame may include one or more centering aids for aligning the sealing plate with respect to said sealing frame during removal thereof. The centering aids may be displaceable underneath a film web by the upper sealing tool part during the clamping of the film web between the sealing frame and the upper sealing tool part.

An apparatus for forming a window of a display panel includes a mold configured to hold a plate in a concave portion, wherein the concave portion has a predetermined shape, and a transfer part configured to sequentially transfer the mold to a heating part, a forming part, and a cooling part. The heating part includes first and second heating modules respectively positioned on top and bottom portions of the mold and configured to apply heat to the top and bottom portions of the mold. The forming part is positioned above the mold and configured to jet a high-temperature gas onto the heated plate. The cooling part includes first and second cooling modules respectively positioned on the top and bottom portions of the mold and configured to cool the top and bottom portions of the heated plate. The mold is tilted at a predetermined angle relative to a horizontal plane.

A thermoforming assembly includes a lower mold part (20) and an upper mold part (34). The two mold parts are able to move in a substantially vertical direction between an open position and a closed position. Retaining members (28) are able to hold a sheet of softened thermoplastic (10) in a substantially horizontal mean plane Pm between the two mold parts. The retaining members include a plurality of rods (28) mounted mobile in the lower mold part (20). The rods (28) project out from the lower mold part (20) when the two mold parts (20, 34) are in the open position, to hold the sheet of softened thermoplastic (10) in the substantially horizontal mean plane Pm and accompany it as the mold closes.
