The present invention has: a step for heating a resin or a metal in a state in which the resin or metal is sandwiched by a mold provided with a projection that is constituted from an elastic body having a heat resistance temperature higher than the temperature at which the resin or the metal softens, and a support body which is larder than the mold and which is softened by heat at a higher temperature than the resin or the metal, while a force is applied to the mold in the direction toward the resin or the metal.

Disclosed herein is an apparatus for fixing a thermoplastic composite. The apparatus for fixing a thermoplastic composite for fixing the thermoplastic composite and placing a transferring tray to be transferred to a forming mold, the apparatus comprising a frame unit having a location space where the thermoplastic composite is positioned and placed on the transferring tray, and a plurality of connecting units for connecting the frame unit and the thermoplastic composite to pull the thermoplastic composite toward the frame unit. In this case, the plurality of connecting units have variable length and move along the frame unit.

Strap welding system and method for welding two ends or sections of a strap around a bundle of articles or around a pressed bale. The strap welding system has a weld assembly for frictionally welding two ends of a plastic strap around a pressed bale. The weld assembly has a weld head with an upper weld jaw and a lower weld jaw, and wherein the lower weld jaw is supported, directly or indirectly, by a spring. A connecting piece for moving the lower weld jaw can optionally have a section with a connecting spring.

This disclosure describes compositions, kits, methods, systems, and three-dimensional parts. According to an example, described herein is a method of forming a polymeric powder build material composition for three-dimensional printing, the method comprising mixing a thermoplastic polymer powder composition, antioxidants, flow aids, a surface modifying agent, antistatic agents, and filler.

An injection mold is configured to form an eyeball for a fishing lure. The injection mold includes a first mold plate, a first stem plate, a second stem plate, and a second mold plate. The first mold plate defines a first injection port. The first and second stem plates and the second stem plate each define a plurality of stem cavities. The second mold plate includes first and second sides and a second injection port extending between the first side and the second side. The second side defines an iris cavity in fluid communication with the second injection port. The injection mold is configured to be assembled in a first configuration, to receive a first flowable material to form a pupil stem of an eyeball, and a second configuration, to receive a second flowable material to form an iris of the eyeball.

A canister including a lid and storage canister. The lid incorporates a gasket that is overmolded onto the lid during its manufacture. The gasket is exposed on both the upper and lower surfaces of the lid in order to provide a non-slip surface at the top portion of the lid and a sealing surface at the bottom of the lid for sealing a storage canister.

A method for producing a part made of composite material includes adding a thermoplastic or thermosetting matrix around a preform of a reinforcing fiber mesh made by filament winding around the spurs or the like of a frame. There is winding in addition to the fibers on one or several reels within the matrix, the axes of the spurs or the like and those of the one or more reels having different orientations, so as to provide the mesh of fibers with a three-dimensional shape.

The present disclosure is drawn to multi-fluid kits for three-dimensional printing, three-dimensional printing kits, and methods of making three-dimensional printed articles. In one example, a multi-fluid kit for three-dimensional printing can include a fusing agent, a first reactive agent, and a second reactive agent. The fusing agent can include water and a radiation absorber. The first reactive agent can include a first liquid vehicle and an epoxy compound having multiple epoxide groups. The second reactive agent can include a second liquid vehicle and an amine compound having multiple amino groups.

A stopcock controls the flow of a liquid under pressure through a dispensing tube with an upstream portion separated by the stopcock from a downstream portion. The stopcock includes a housing portion with a chamber defined by a housing peripheral wall surrounding a longitudinal z-axis. The housing peripheral wall has an inner surface of revolution with a housing inlet opening connectable to the upstream portion of the dispensing tube. The stopcock includes an outlet connector connectable to the downstream portion of the dispensing tube and comprising an outlet opening. A plug defined by a plug outer peripheral wall snugly fitting the inner surface of revolution of the housing peripheral wall. The plug can rotate within the chamber about the longitudinal z-axis. The plug has a through-channel extending from an upstream opening located on the plug outer peripheral wall, to a downstream opening, such that the plug can be rotated about the longitudinal z-axis from a flow position to a sealed position, wherein, the plug outer peripheral wall comprises a seal protrusion topped by a ridge and forming a closed loop defining a blank area of the plug outer peripheral wall, such that, in the sealed position, the housing inlet opening of the housing peripheral wall faces the blank area and is circumscribed within the seal protrusion. The plug outer peripheral wall has a flow protrusion topped by a ridge circumscribing the upstream opening such that, in the flow position, the inlet opening of the cylindrical chamber peripheral wall is circumscribed by the flow protrusion, wherein said flow protrusion preferably shares a common portion of protrusion with the seal protrusion.

A seal carving apparatus includes a thermal head having a plurality of heat generating elements disposed in lines, and thermal drive control means that performs a control process of selectively and thermally driving the individual heat generating elements while moving the thermal head and a porous material in relative to each other with the thermal head being in abutment with the porous material, thereby forming a seal face on the porous material. The thermal drive control means controls a pulse time width for thermally driving the individual heat generating elements of the thermal head under pulse width modulation control based on gradation image data having a gradation value, thereby forming a seal with a gradation on the porous material.
