Method of producing molded article
A method of producing a molded article includes: laminating an adhesive sheet including an acrylic-based polymer and a polymerization initiator onto resin film, to produce a resin laminate; and covering an adherend with the resin film while the resin laminate is pressed against the adherend, and the resin film is stretched following a surface shape of the adherend. In planar view, the resin laminate is larger than the adherend. The covering step includes heating the resin laminate at 100° C. or higher and 180° C. or lower, superposing the resin laminate on the adherend planarly and pressing the resin laminate and the adherend under a reduced pressure environment, and then applying pressure to an environment opposite to the adherend with respect to the resin film. The adhesive sheet has an exothermic peak of 100° C. or higher and 180° C. or lower in differential scanning calorimetry at a temperature raising rate of 10° C./min.
Shaping system, shaped object formation method, and computer-readable storage medium
A shaping system includes: a printing device that prints an image using predetermined ink on a thermal expansion sheet having a thermal expansion layer on one side; and an expansion device that performs: a drying process of heating the thermal expansion sheet to an extent that allows the thermal expansion layer to maintain a non-expansion state, to dry the image printed by the printing device using the predetermined ink; and an expansion process of, after the drying process, heating the thermal expansion sheet to an extent that allows the thermal expansion layer to expand, to expand the thermal expansion layer.
Thermoforming machine and method
A thermoforming machine is provided having at least one frame member and a thermal regulator. The thermal regulator is provided in heat transfer relation with one of the at least one frame member configured to control temperature of the one frame member to mitigate thermal deformation of the frame member. A method is also provided.
Methods and devices of forming a tensioned stringer for a vehicle
Methods and devices of fabricating a stringer for a vehicle. The stringer can be constructed from two charges that are formed together into the stringer. During fabrication, the charges are placed over support members with the ends of each charge extending over a die cavity. The charges are secured and a punch die forces the first ends into the die cavity forming blades of the stringer. The charges are secured thus tensioning the charges during the punch process.
Bulk textured material sheeting
A material including a metal sheet, a first plurality of raised and pointed structures, and a second plurality of raised and pointed structures is provided. The metal sheet includes first and second opposed sides, and a thickness between the first and second opposed sides. The first plurality of raised and pointed structures are gouged out of the first side of the metal sheet. The sheet is not perforated, and the raised and pointed structures of the first plurality have a height of between 150% and 300% of the thickness. The second plurality of raised and pointed structures are gouged out of the second side of the metal sheet.
Hard case for containing objects and manufacturing method thereof
A hard case for housing and transporting objects includes a first shell and a second shell, hinges for connecting the shells and enabling the latter to be arranged in a closed configuration or in an open configuration, and a closing device to lock the shells in the closed configuration. The shells include respective main panels formed by thermoforming an interwoven polypropylene sheet including a plurality of superimposed layers, each layer having oriented polypropylene fibers therein, the layers being arranged to interweave the superimposed fibers, and respective side elements including respective interface edges intended to be coupled to each other in the closed configuration. The side elements are made of polypropylene by injection molding and are fixed to the main panels to carry out respective joining portions in which the injected polypropylene of the side elements and the interwoven polypropylene of the main panels are melted and joined to each other in order to form the shells in a single part and entirely made of polypropylene.
Multifunctional adhesive film for the surface protection of workpieces
A multilayer thermoformable film to protect the surface of a workpiece includes an underlayer having first and second faces. The underlayer is made from an adhesive material configured to adhere to the surface of the workpiece by the first face. At least one layer of polymer material is attached to the second face of the adhesive underlayer. The layer of polymer material is resistant to erosion by solid particles and to erosion by liquid particles. It is formed from a polymer material chosen from a polyurethane, a polyether ether ketone and a polyethylene having a very high molecular weight, with a Shore D hardness of between 50 and 65 D. A method of surface protection of the workpiece includes thermoforming the film in a shape adapted to match the shape of at least a portion of the workpiece and applying the film thermoformed onto the surface of the workpiece.
Flexible metal polymer composites
The invention relates to a flexible polymer composite containing metal particles, to the method for producing said composite, and to the uses of said composite.
FIREARM HOLSTER
A firearm holster includes a plate that is folded to form a cavity. The cavity is defined by a first sidewall, a trigger sidewall adjacent to the first sidewall, a second sidewall adjacent to the trigger sidewall, a barrel sidewall adjacent to both the first and second sidewalls, and a muzzle end wall. The muzzle end wall is adjacent to the first sidewall, the trigger sidewall, the second sidewall and the barrel sidewall. The firearm holster also includes a support wrap that at least partially surrounds the cavity and is fused to one or more of the first sidewall, the barrel sidewall, and the second sidewall.
Roll-molding
Discrete male touch fastener elements are molded of thermoplastic resin extending from a common, flexible base sheet, by introducing molten resin to a molding nip between two counter-rotating rolls consisting of a mold roll and a pressure roll arranged such that their rotation axes are parallel and together define a common plane containing each of the rotation axes. Solidified resin is stripped from molding cavities of the mold roll after the cavities have passed a rotating reaction roll forming a pressure nip with the mold roll. The reaction roll is spaced from the pressure roll by a distance less than an outer diameter of the mold roll, and the mold roll is simultaneously held against both the pressure roll and the reaction roll in a non-planar roll stack.
