Package, method for manufacturing a package, and mold for application for the purpose of such method
A package comprises an entirety of a tray (10) having an open side and a ring-shaped cover rim (20) which is located at the open side of the tray (10), at an outer circumferential rim (16) of the tray (10), and which is connected to the tray (10) through a relatively weak breaking portion (30). For the purpose of manufacturing the package, a mold (41) is provided. Also, a sheet (40) is provided and placed in the mold (41), wherein a movement of the sheet (40) is forced in two different directions. The cover rim (20) is formed with an inner ring (21) in which an inward bulge (28) is realized, along at least a portion of the circumference thereof, as an aids in establishing a clamping connection between the cover rim (20) and the tray (10) once the cover rim (20) has been broken away from the tray (10).
DEVICE, MOULD ASSEMBLY AND METHOD FOR THERMOFORMING OF A PRODUCT FROM A PLASTIC FILM
A device and method for thermoforming of a product from a plastic film includes a mould assembly which is used in such a device. The plastic film is clamped between the mould parts in primary and secondary manner. The forming process can hereby be divided into more or less independent zones. Different forming techniques, positive or negative, can be used in the different zones. This makes it possible to combine the advantages of the two techniques in one forming process.
Structure manufacturing method and retaining device
A manufacturing method of a structure by which a target member can be easily positioned with high accuracy. In a tilting step, at least one target member is positioned by tilting a positioning table and sliding the target member placed on the positioning table to bring the target member into contact with a locking portion.
METHOD FOR MANUFACTURING AN AIRCRAFT SEAT PART
A method for manufacturing a part for an aircraft seat includes positioning a heating frame around a stacked structure, locally heating an edge of the stacked structure using a heating frame, externally heating the entire stacked structure, positioning the stacked structure inside a thermoforming mould provided with cutting punches, closing the thermoforming mould and applying a vacuum to the interior of the thermoforming mould, to simultaneously perform, during the same step of shaping the first cover and the second cover, a step of heat sealing an edge of the first cover to an edge of the second cover, bonding the first cover and the second cover to the foam core, and cutting the stacked structure along the circumference thereof using cutting punches.
METHODS FOR ORTHODONTIC APPLIANCE FABRICATION AND ORTHODONTIC APPLIANCES MADE THEREBY
A dental aligner and methods and systems for manufacturing the dental aligner. A boundary contour is defined in a two-dimensional space based on an edge of a model aligner in a ruler disc. The boundary contour may be measured on a grid in which the model aligner is formed. The information pertaining to the boundary contour in the model is transferred to a flat workpiece. The boundary contour may follow the patient's gingival margin. A trench is formed in the flat workpiece based on the boundary contour measured in the model aligner. The flat workpiece including the trench is deformed. Deforming the trench forms at least a portion of the edge of the dental aligner and may include a trim boundary. The aligner may be separated from the workpiece at the trim boundary. The model aligner and dental aligner may vacuum thermoformed from the same mold.
MOLDING DIE DEVICE AND MOLDING METHOD
A molding die device is provided for bringing a resin sheet into close contact with a pair of dies by vacuum suction from a cavity surface to perform molding. An outer frame portion is formed integrally with an outer peripheral portion of the respective dies arranged to face each other. Moreover, one of the dies has a recessed portion formed at the position of the one of the dies facing the outer frame portion of the other die and configured so that the outer frame portion of the one of the dies can be housed in the recessed portion. The outer frame portion is formed to protrude most in each die. Upon molding, the dies are clamped together after vacuum suction has been performed with the resin sheet being arranged in contact with the outer frame portions.
MICROPROJECTION IMPLEMENT AND METHOD FOR PRODUCING SAME
A microprotrusion device (1A) according to the present invention includes a needle-like and hollow first protrusion portion (3) that is formed so as to protrude from one surface (2a) of a substrate sheet (2) and a hollow second protrusion portion (4) that is formed so as to protrude from a vicinity of the first protrusion portion (3) on the one surface (2a) of the substrate sheet (2) and has a protrusion height lower than that of the first protrusion portion (3). The first protrusion portion (3) has an opening at its tip end portion, and a hollow portion (30) of the first protrusion portion (3) is in communication with the outside via the opening portion (31). The opening portion (31) is formed at the tip end of the first protrusion portion (3).
Molding device and molding method of a fuel tank flange section
A fuel tank flange section molding device including: upper and lower molds that are closed together to mold a fuel tank; a fixed section that controls an amount of molten resin flowing toward a fuel tank main body side due to the protruding portion being disposed nearer to the lower mold side than the mold face when the upper and lower molds have been closed together; a flange insert that includes a mold face capable of rotating about the fixed section to an angle sloped toward a retracting direction of the upper mold, with respect to an extension direction of the flange section; and a cut-off insert that includes a mold face that forms an end portion of the flange section at the opposite side from the fuel tank main body, and that is capable of retracting from the upper mold with respect to the lower mold.

Method for producing a container from thermoplastic material
The invention relates to a method for producing a container from thermoplastic material having a connection element (5) passing through the wall thereof. The method comprises making available at least one plate-shaped or shell-shaped or tube-shaped preform (3) made of plasticized thermoplastic material, introducing the preform (3) into a multipart molding tool (1) having cavities defining at least one molding recess, molding and final shaping of the preform (3) within the molding tool (1) using differential pressure, piercing of the still warm-plastic preform (3) from the tool side by means of a mandrel (9) in order to produce an opening (6) in the preform (3), insertion from the molding recess side of a connection element (5) into the opening (6) produced by the mandrel (9), and connection of the connection element (5) to the preform (3).
