A method and apparatus for applying sealant. The apparatus may comprise a shaping portion, a centering portion, and a support system. The shaping portion may have a cavity configured to receive a fastener system and receive a sealant. The centering portion may have a channel configured to position the shaping portion in a desired position around the fastener system when the fastener system is received in the cavity. The support system may be configured to maintain the desired position of the apparatus.

A method for manufacturing a sandwich component includes applying at least one matrix material to the upper side and/or the underside of at least one material blank, and arranging the material blanks above one another and/or next to one another. At least two of the material blanks differ in design or matrix material may be applied in different ways along the upper side and/or underside thereof, or matrix material is applied in different ways to at least one of the material blanks along the upper side and/or underside thereof. In that way, at least one horizontal and/or vertical zone of the sandwich component is created having different mechanical properties than other regions of the sandwich component. The material blanks are then pressed to form the sandwich component.

A hollow-fiber-type blood processing device and methods for its manufacture include a hollow fiber membrane bundle which is obtained by bundling a large number of hollow fiber membranes into a columnar shape. A sheet body is mounted on an outer peripheral portion of the hollow fiber membrane bundle. The sheet body is expandable as a result of being woven from a sheet material. An inner diameter of the sheet body in a natural state where no external force is applied to the sheet body is smaller than the outer diameter of the hollow fiber membrane bundle.

Wood-type golf clubs and/or golf club heads include: (a) a golf club head base member including a face member having a ball striking face; and (b) a polymeric body member engaged with the golf club head base member, wherein the polymeric body member is formed via a rotational molding process (or other centrifugal force inducing molding process) and/or engaged with the golf club head base member via a rotational molding process (or other centrifugal force inducing molding process). The polymeric body member forms at least a portion of a crown member of the club head in some structures.

Various implementations include a method of curing of thermoset resin. The method includes disposing one or more thermoset resin layers in a layup; disposing one or more heaters in the layup, wherein each of the one or more heaters includes two electrodes, wherein the two electrodes of each of the one or more heaters are couplable to an external electricity source when the one or more heaters are disposed in the layup; and providing enough electricity to the electrodes of each of the one or more heaters to cause the one or more heaters to heat the layup to fully cure the one or more thermoset resin layers to form a cured laminate.

A method of forming set pin hole of an insulated carbine hook includes: providing a core material with a perforation and a recess; putting the core material in a mold cavity of a mold including a movable pin protruding from an inner surface of the mold cavity, which is at an opening of the perforation; filling insulated material between an outer surface of the core material and the inner surface, and in the perforation and recess; forming an insulated layer on the outer surface and in the perforation and recess to obtain an insulated intermediate having a notch at the opening; aiming a removal tool at the notch; removing the insulated material at the other opening of and in the perforation, and at an opening of and in the recess to form the set pin hole, which makes the manufacturing a main body of the insulated carbine hook easy.

In certain embodiments, a system for making an implant for an eye comprises a printer, a camera, and a computer. The printer prints material onto a target and has a printer head and printer controller. The printer head deposits the material onto the target, and the printer controller moves the printer head to deposit the material onto a specific location of the target. The camera generates an image to monitor the printing of the material. The computer stores a pattern for the implant, which is designed to provide refractive treatment for the eye; sends instructions to the printer controller to move the printer head to print the material onto the target according to the pattern; assesses the image from the camera according to the pattern; and adjusts the instructions in response to the image.

A method for producing a high-pressure tank capable of suppressing break of a surface resin layer due to gas pressure as well as degradation in the tank quality. The method includes winding a thermosetting resin-impregnated fiber bundle around a liner so as to form an uncured fiber-reinforced resin layer thereon, first heating in which the uncured fiber-reinforced resin layer is locally heated at a first temperature so as to leach the thermosetting resin out of the uncured fiber-reinforced resin layer to form the surface resin layer, and the surface resin layer is cured to have cracks generated therein, and second heating in which the tank is entirely heated at a second temperature lower than the first temperature, so that the fiber-reinforced resin layer and surface resin layer are entirely cured, so as to obtain the tank with the surface resin layer locally having cracks generated therein.

A method for hardening a preform into a composite part is provided. The method comprises aligning a layup mandrel carrying a preform for insertion into an autoclave having an inner surface that is complementary to a contour of the preform. The layup mandrel is then sealed into the autoclave.
