A method for producing a bonded magnet, comprising: (i) low-shear compounding of a thermoplastic polymer and magnetic particles to form an initial homogeneous mixture thereof; (ii) feeding the initial homogeneous mixture into a plasticator comprising a low-shear single screw rotating unidirectionally toward a die orifice and housed within a heated barrel to result in heating of the initial homogeneous mixture until the thermoplastic polymer melts and forms a further homogeneous mixture, wherein said further homogeneous mixture is transported within threads of the single screw towards the die orifice and exits the die orifice as a solid pellet; (iii) conveying the solid pellet into a mold and compression molding the pellet in the mold, to form the bonded magnet, wherein the bonded magnet possesses a magnetic particle loading of at least 80 vol % and exhibits one or more magnetic properties varying by less than 5% throughout the bonded magnet.

The present subject matter relates to systems, devices, and methods of enhancing carbon fiber dispersion in wet-laid nonwovens. A quantity of fibers is deposited in a medium, and each of one or more stirring elements is moved in a pattern to mechanically agitate the medium. In some embodiments, moving each of the one or more stirring elements includes moving the one or more stirring elements in complementary patterns to induce a chaotic advection current within the medium.

A stripping lifting insert is provided for precast insulated panels having an insulating material layer between opposing wythes, the insulating material layer, wythes, and precast insulated panel having respective widths. The stripping lifting insert includes an elongated connecting shaft having a shaft axis. First and second spaced apart wythe engagement members are connected to the connecting shaft in spaced apart relation to each other. Each wythe engagement member includes a hub and a plurality of three or more protrusions connected to and emanating from hub. Each of the protrusions extending radially outward from the shaft axis. The wythe engagement members have a height less than the width of the wythes, whereby each wythe engagement member can be completely embedded in a respective wythe of the precast insulated panel. A precast insulated panel and a method of making a precast insulated panel are also disclosed.
