A member joining method includes: a placement process of arranging a first member and a second member inserted into the first member so that a gap surrounding the second member is provided between the first member and the second member; a filling process of filling a molten resin into the gap and applying pressure to the resin so as to cause at least one member of the first member or the second member to undergo elastic deformation; and a pressure maintaining process of maintaining the pressure until the resin that has been filled into the gap has cured.

Embodiments herein relate to hollow profiles and methods of preparing the same for joining operations. A method herein can include placing a dam within a channel defined by the hollow profile, fitting a die block over an end of the channel, and injecting a flowable composition through an injection port into the channel. Another method can include defining a volume within a first member using at least one flow control device, filling the defined volume with a flowable polymeric composition, allowing the flowable polymeric composition to solidify to form a solid portion in the first member, and mechanically modifying the solid portion to define a joining surface suitable for joining to the second member. Other embodiments are also included herein.

Disclosed is an end welding mold for providing end welding in all moving or fixed glass profiles of vehicles via injection method, having at least one mold core providing geometric shaping of the paste which is transferred by a hot runner system or a cold runner system, which is changeable depending on different end welding references. It could also be applied to dynamic sealings ends (eg. door seals) on cars if they have an end moulding.

Goggles are described as including an outrigger, an elastic band, and one or more cages. The elastic band is coupled to the cage, which may then be disposed within an opening of the outrigger. Thus, the elastic band may be coupled to the outrigger and, accordingly, to the goggle frame, through cage. Such a configuration may allow for the elastic band to have a stronger and more compact coupling to the outrigger and/or goggle frame. The cage may comprise metal or another material stronger than the material of the goggle frame and/or the outrigger. Furthermore, the cage may be more compact (e.g., narrower) than a typical connection while maintaining or improving strength.

A method of forming a hollow article includes injecting a first molding material into a first mold cavity at a first injection pressure to form a first molded shell and injecting a second molding material into a second mold cavity at a second injection pressure to form a second molded shell. The first molded shell has a first peripheral edge, and the second molded shell has a second peripheral edge. The method includes positioning the first shell and second shell into facing relation with the first and second peripheral edges in a third cavity, and injecting a third molding material into the third cavity at a third injection pressure to bond together the first and second shells along the first and second peripheral edges to form the hollow article. The third injection pressure is less than the first injection pressure by at least about 3.5 bar.

In one embodiment, a method for fabricating a neurostimulation stimulation lead comprises: providing a plurality of ring components and hypotubes in a mold; placing an annular frame with multiple lumens over distal ends of the plurality of hypotubes to position a portion of each hypotube within a respective lumen of the annular frame; molding the plurality of ring components and the hypotubes to form a stimulation tip component for the stimulation lead, wherein the molding fills interstitial spaces between the plurality of ring components and hypotubes with insulative material; and forming segmented electrodes from the ring components after performing the molding.

A helmet manufacturing method involves: producing a shell and a protector, the shell having two opposing cheek-protecting portions, the protector having a jaw-protecting portion and a neck-protecting portion connected to the jaw-protecting portion; putting the shell and the protector in a die such that bottom edges of the cheek-protecting portions of the shell connect to a top edge of the neck-protecting portion of the protector; introducing a foam material into the die, apply heat and pressure to the foam material such that the foam material expands and binds to an inner side of the shell and an inner side of the protector; and taking a helmet finished product out of the die. Therefore, both the jaw-protecting portion of the integrally-formed protector and the helmet finished product are reinforced.

A molded plastic article having a bonded plastic portion 6 bonding a first body and a second body together; a connecting plastic portion 8, formed by solidifying the molten plastic flowing out from the plastic channel, having one end connected to the bonding plastic portion 6; and a flow tab plastic portion 7 formed by solidifying the molten plastic, connected to the other end of the connecting plastic portion 8 connected to the other end portion of the 8. A portion of reduced diameter 7a is provided to the flow tab plastic portion 7 on the connecting plastic portion side.

A method for forming a component exhibiting a sealed interior, including providing first and second mold halves, foaming first and second half shells of material within cavities defined within each of the mold halves, and upon mating the mold halves together in a first closed mold configuration. The mold halves are reopened, with at least one of the shells being subsequently reoriented such that the first and second half shells are arrayed in opposing fashion with perimeter extending edges of each half shell arranged in contact with one another. Additional steps include reclosing the mold halves and subsequently forming a second perimeter extending material in contact with the contacting perimeter extending edges in order to bond the half shells together, upon which the mold halves are reopened and a completed component removed.
