A method for producing a structural component from an organometallic sheet includes a first step in which the organometallic sheet is preheated, introduced into a tool and subsequently re-formed. In a second step, a region of the re-formed organometallic sheet is heated. In a third step at least the heated region of the re-formed organometallic sheet is re-formed further in such a way that it enters into a material bond with a further region of the organometallic sheet to form an at least partly closed hollow profile. A device for carrying out the method for producing a structural component from an organometallic sheet and a structural component produced by the method also are described.

A vacuum bagging system may include a layer assembly defining a fluid flow channel. The layer assembly may include a contact layer mounted to a composite part positionable within an outer mold line (OML) tool. The contact layer may have a contact layer width defined by opposing contact layer side edges. The layer assembly may further include an inner layer mounted to the contact layer and having inner layer side edges located between the contact layer side edges. The fluid flow channel may extend along at least a portion of the composite part to at least one part end. The vacuum bagging system may include an internal vacuum bag positionable against the inner layer. An inner mold line (IML) tool may support the internal vacuum bag. The contact layer width may be less than an IML tool width.

A printing method for printing a multi-material 3D model comprises the following steps: perform a slicing process on a multi-material 3D object to generate the multi-material object slices and the object slices of a useful object; compute a material-switching point and a retrieving point during the slicing process; print the multi-material object slices of a multi-material 3D model with one of the materials; when print to the material-switching point, switch to another different material and print useful objects with the material used before the material switching; when print to the retrieving point, print the multi-material object slices with the material used after the material switching; and repeat the above steps until completing the multi-material 3D model printing. The present disclosed example prints the useful object via the remaining materials after the material switching which effectively reduces the cost with of multi-materials printing.

A large animal feed dispensing container and method of manufacturing the container and method of using the device for delivering a controlled amount of feed to large animals in an outdoor. The housing unit and transecting plate may be molded as a single fused piece. The housing unit includes small openings intended for dispensation in the first chamber that contains feed. The housing unit contains a container for ballast material keep the feed-dispensing container to stabilize the feed-dispensing container in one location.

An axle housing for a vehicle is provided. The axle housing includes a polymeric composite body. The polymeric composite body includes a polymer and a plurality of reinforcing fibers. The polymeric composite body has a modulus of greater than or equal to about 10 GPa. The polymeric composite body defines an inner surface and at least one bearing region. The inner surface defines an interior cavity. The interior cavity is configured to receive an internal gear set including a bearing. The at least one bearing region includes a bore. The at least one bearing region is configured to be disposed around the bearing of the internal gear set. The axle housing may unibody, such that a body portion is free of joints or seams, or it may include multiple pieces. Methods of manufacturing composite axle housings are also provided.

Within examples, methods and systems for a multi-state bladder or elastomeric apparatus for manufacture of composite material are provided. The elastomeric apparatus includes a housing having a flexible surface state and a rigid surface state, a rod within the housing extending along a length of the housing, and a plurality of components mounted to the rod, such that in an engaged position of the rod the plurality of components cause the housing to have the rigid surface state, and in a disengaged position of the rod the plurality of components enable the housing to have the flexible surface state.

A method for fabricating flexible microfluidic chips with plastic membranes. In particular, the present invention provides a single-step method for microchannel fabrication of microfluidic chips in a fast and cost-efficient manner.

A method for molding fiber-reinforced plastic. A core is formed in a desired shape by accommodating, in a flexible bag, a grain group containing plurality of grains. The core is placed inside a prepreg containing resin and fibers, and the prepreg, in which the core is housed is placed in a molding die and compression molded. When doing so, the grain group contains first and second grains (a,b) that satisfy the equation (1). (1) 1.1(Da/Db)2.0 In the equation Da is the grain diameter of the grains (a), and Db is the grain diameter of the grain (b). When using a molding die to mold a molded article having a cavity, the above mentioned molding method enables an increase in the internal pressure of the core in order to change the peripheral surface area of the core, without using a pressurized gas and/or pressurized liquid.

A method of sealing a peelable lid (2) to a flange (4) provided within a metal can body (1) which involves inserting an induction coil (6) into the can body to primarily heat the sealing surface (5) of the flange, while keeping the exterior wall of the can relatively cool to avoid tin reflow and decoration degradation of the exterior wall. The induction coil is subsequently removed from the can body and a peelable lid applied to the flange, whereby residual heat in the flange aids the sealing of the lid to the flange, e.g. by allowing activation of a bonding material.

Provided are a method for producing a tank with an outer surface profile that allows an elastic protective member to be easily and firmly attached to a surface thereof, and also such a tank with a protective member. The method for producing the tank, which includes winding fiber bundles containing an uncured resin component in multiple layers around the outer surface of a liner in a first pitch width so as to form a fiber reinforced resin layer and securely bonding the protective member to a portion of the outer surface thereof, further includes: winding the fiber bundles in a second pitch width wider than the first pitch width so as to form a gap with a required width where no fiber bundle is present between adjacent fiber bundles in winding the fiber bundles to form an outermost fiber bundle layer; shaving off a tip end portion of a projection made of a resin that has cured after bleeding into the gap, with a portion thereof left unshaved so as to form a sharpened portion; and securely bonding the protective member to the sharpened portion while pressing it from above.
