A formation device melts a plastic material and places the melted plastic material into a mold. The mold has an upper case, a lower case and a cavity, and a blowing aperture is disposed at a conjunction area of the upper and lower cases and extending to the cavity. The formation device utilizes a blowing tube to connect to the blowing aperture to reach into the plastic material in the cavity. During a blow molding process, the formation device inflates the plastic material through the blowing tube such that the plastic material expands to conform with a shape of the cavity, and when the mold is opened, a hollow casing member is obtained. The casing member further comprises a framed base, and two opposite sides of the base respectively connected to a top board and a bottom board via a connecting lip.

A hot press cushioning material (10) of the present invention includes, as a base material, a woven fabric layer (11) using bulky yarn (12) as at least one of the warp and weft, and a nonwoven fabric layer (14) placed on one surface side of the woven fabric layer (11), a part of the nonwoven fabric layer (14) being embedded in the woven fabric layer (11). A nonwoven fabric-resin composite layer (18) is formed in the opposite surface of the nonwoven fabric layer (14) from the woven fabric layer (11) by impregnation with resin (15). A woven fabric-rubber composite layer (19) is formed in the other surface of the woven fabric layer (11) by impregnation with rubber (16). The nonwoven fabric-resin composite layer (18) and the woven fabric-rubber composite layer (19) have voids (17) therein.

In one embodiment of an apparatus for manufacturing a rubber sheet, a continuous rubber material is supplied onto a supply conveyor in a meandering state by supplying the continuous rubber material onto the supply conveyor while moving rubber supply device in a reciprocating manner in a roll axial direction. The rubber supply device has a full width moving mode in which the rubber supply device moves in the roll axial direction such that the continuous rubber material has a meandering shape of a width corresponding to a width of a rubber sheet, and a partial width moving mode in which the rubber supply device moves in the roll axial direction such that the continuous rubber material has a meandering shape of a width obtained by excluding widths of both edge portions of the rubber sheet from the width of the rubber sheet.

On-line synchronous registering co-extrusion SPC floor includes a base material layer, a decorative layer, and a wear-resistant layer. The decorative layer is arranged on the base material layer and provides patterns and designs. The wear-resistant layer is arranged on the decorative layer, is a transparent layer or a semi-transparent layer, and is provided with a concave-convex surface. The patterns or designs correspond to the concave-convex surface; the base material layer is composed of an elastic layer, a strength layer, and a stable layer, and shading is pressed on the bottom layer of the stable layer. Two co-extrusion lines are used for simultaneous extrusion to achieve an ABA three-layer effect of an SPC base material layer. A calender matches a synchronous registering system, and the patterns of the decorative layer are formed in a rolling manner.

A method of manufacturing a structure is provided in which a burr portion can be more reliably cut. In a burr portion shaping step, the burr portion is sucked to an engaging portion by a suction part to shape the burr portion along the engaging portion, and in a cutting step, ae movable portion is moved relative to first and second split molds with the burr portion being shaped along the engaging portion, thereby the burr portion is cut from a molded main body along a cutting line.

A method for the production of objects including at least one honeycomb panel is performed by setting up a honeycomb panel and engraving it in such a way as to create a deposition path with a predetermined depth. A filler material is applied along the deposition path so as to fill it at least partially.
