    Abstract: Disclosed is a conformal cooling channel design method using a topology optimization design. The conformal cooling channel design method using a topology optimization design according to an embodiment of the present invention includes the steps of: classifying a molded product as a thin structure or a bulk structure, and determining a cooling target area; decomposing the cooling target area into cooling target surfaces of two-dimensional shape; forming cooling channels independent from each other using a topology optimization design for each of the cooling target surfaces; and forming a conformal cooling channel by combining the cooling channels. According to the present embodiment, there is provided a method of designing a conformal cooling channel inside a mold after determining a cooling target surface by classifying the shape of a molded product as a bulk structure or a thin structure and forming an independent cooling channel for each cooling target surface using a topology optimization design.

    Abstract: Extrusion apparatus and methods for use in the design and operation of extrusion screws having multiple channels. In response to rotation of an extrusion screw in an extrusion process, the multiple channels of the extrusion screw can control the temperature, pressure, and/or shear rate of feedstock material flowing through the respective channels. The multiple channels of the extrusion screw can be configured to control the temperature, the pressure, and/or the shear rate of the processed feedstock material by being modeled as one or more model objects having one or more predetermined geometries. The models of the respective channels can then be analyzed using computerized analytical and/or numerical techniques in order to obtain at least estimates of desired temperatures, pressures, and/or shear rates of the processed feedstock material, based at least on specified channel lengths, channel widths, and/or channel depths of the respective channel models.

    Abstract: A method for fabricating a product, such as an animatronic character, with artificial skin. The method includes providing data defining an exterior surface geometry of the product. A base geometry model of the product is generated based on the exterior surface geometry data, which in turn is used to fabricate a prototype of the product. Then, an exterior skin mold is formed using the product prototype mounted on an alignment block. The method includes fabricating an inner support structure based on the base geometry model having an exterior geometry smaller than the 3D base geometry model by the thickness of the exterior skin. The inner support structure is positioned within the mold with the inner support structure mounted upon the alignment block, which is received in the mold. The product is formed by pouring material for an exterior skin layer into the mold and over the inner support structure.
