A housing having a rotary axis and configured to support at least one radially projecting cutting component that effects cutting as the housing is turned around the rotary axis. The housing has a first housing part with a first wall and a plurality of discrete circumferentially spaced cavities in the first wall and each having a volume. The volumes of at least a first and second of the cavities respectively at first and second locations are different and strategically selected to cause a mass distribution on the housing that contributes to improved dynamic balancing of the housing as the housing is turned around the rotary axis.

A functional polymeric cutting edge structure and methods for manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.

The technology described herein relates to a system of stackable/nesting stencils or molds for creating 3-D objects using a modeling compound material. The stencils or molds can be filled with the modeling compound material by hand and/or leveled using a roller to flatten the compound material more smoothly for a better outcome. Each stencil has a level and nests with another corresponding stencil of the set in a designated order. In some aspects, in order to guide a user with the correct designated order in which to fill the stencil plates or molds, each stencil plate or mold may be provided with a numbered tab. Once all the stencils are filled in the designated order with modeling compound materials, the stencil plates can be removed level by level to reveal a finished 3-D object. These 3-D objects may be anything from characters, vehicles, objects, figurines, and the like.

A method of manufacturing a window surround for a vehicle, a window surround for a vehicle, and a device for manufacturing a window surround. The window surround includes a first component to serve as a circumferential support frame to hold a window glass panel, a second component, composed of a material of less hardness than the material of the first component, onto the first component, to serve as a circumferential sealing element, and a third component that is composed of a high gloss material. The method includes injection molding the first component onto a window glass panel, then injection molding the second component onto the first component, and then injection molding the third component onto the first component.

A mold for manufacturing a turbomachine fan casing made of composite material, includes a main axis mandrel around which a fibrous preform of a fan casing is intended to be wound; a plurality of counter-mold angular sectors assembled on the outer contour of the mandrel which are intended to close the mold and to compact the fibrous preform wound on the mandrel; wherein a flat seal with a main elongation axis directed along the main axis is arranged between each angular sector, the flat seal being compressed between two adjacent angular sectors, a first angular sector including a sealing portion passing below a lower face of the flat seal while a second angular sector including a sealing portion passing above an upper face of the flat seal.

An acoustic attenuation panel for a propulsion assembly includes an acoustic front skin having perforations, and a central structure formed from partitions arranged perpendicularly in order to make up cells, wherein the front skin and the central structure form the panel which is made as a single piece and is provided for directly covering a surface of an element of the propulsion assembly forming a rear skin which closes the cells of the central structure at the rear.

A covering device for a component space in a tool for producing fiber composite components is a multi-layer pre-fabricated material cloth provided with a gas-permeable, matrix material-impermeable membrane. A gas-impermeable, matrix material-impermeable film is provided. Membrane and film are connected at their circumferential rims to delimit an evacuation space with a flow aid and closed by a matrix material-tight connection. Gas having passed from the component space through the membrane into the evacuation space is evacuated through an opening of the film away from the component space. A contact element arranged at a side of the film facing away from the evacuation space surrounds the opening of the film. It is connected matrix material-tightly to the film. The contact element has a contact surface at a side facing away from the film for attaching the covering device to an inner side of a tool wall delimiting the component space.

An apparatus for molding a part includes a plunger cavity, a plunger, and a mold cavity, wherein the plunger is oriented out-of-plane with respect to a major surface of the mold cavity, and first and second vents couples to respective first and second portions of the mold cavity. In a method, resin and fiber are forced into the mold cavity from a plunger cavity, and at least some of the fibers and resin are preferentially flowed to certain region in the mold cavity via the use of vents.

The present invention relates to a freeze-drying mold and a method for manufacturing water-soluble polymer balls using the same, more specifically to a freeze-drying mold that is provided with a first mold having a plurality of first accommodation grooves formed on underside thereof and a plurality of discharge portions formed on top thereof to communicate with the plurality of first accommodation grooves and a second mold having a plurality of second accommodation grooves formed on top thereof to be facingly coupled to the plurality of first accommodation grooves of the first mold to thus provide a plurality of accommodation portions, and a method for manufacturing water-soluble polymer balls using the same.

According to the present invention, the freeze-drying mold is capable of controlling the shrinkage rate of a solution in a freeze-drying process to make freeze-dried spherical materials, easily separating the made freeze-dried materials therefrom, and optimizing a drying efficiency thereof, and the method for manufacturing water-soluble polymer balls using the same is carried out so that the water-soluble polymer balls are constant in pore sizes and distributions, have high strength, and do not have any films on the surfaces thereof.
