摘要:
A process and associated system for creating color effects in extrudable material, such as plastic and metal for example, are presented. Flows of first and second viscous materials of respective colors are provided and then combined in a predetermined pattern to form a stream of combined viscous material. In a first aspect, the flow rate of the first viscous material is caused to vary over time in order to vary an amount of the first viscous material in the stream. In a second aspect, which may be used alone or in combination with the first aspect, the first and second viscous materials have distinct viscosities to reduce an amount of color blending between the first color and the second color in the stream of combined viscous material. A static mixer may then be used to apply a predetermined dividing, overturning and combining motion to the stream of combined viscous material to partially mix the first viscous material and the second viscous material, such that upon exiting the static mixer, the first material of the first color and the second material of the second color form a color pattern in the stream of combined viscous material. Sheets of extrudable material may be created using such process and used in the manufacturing of many different products including for example kayaks and stand-up paddle boards.
摘要:
A method of making a composite board and a product made thereby are disclosed. The method includes a lining forming step, a fiber pipe rolling step, a fiber pipe mounting step, a fiber material covering step, and a board body forming step. The product includes a lining acting as a board body, a plurality of long slots formed on the lining, a fiber pipe placed in each of long slots, a foam material mounted in each of fiber pipes, and a fiber material covering an external periphery of the lining. The fiber materials and the fiber pipes are melted and combined together by heat, thereby shortening the operating time. The fiber pipe becomes a reinforcement support structure to increase a structural strength of the composite board, thereby producing a finished product with a light weight and a strong structure.

The invention provides a method of producing an object made of a composite material said object being relatively strong and light weight and having a complex three-dimensional configuration. The method involves bonding a series of shaped sections of material each with a laminated face to form the object which when laminated, ties the internal and external laminations together to form an array of structural members. The method provides the added advantage that the object may be formed without using a mould.

An article such as a surfboard with a hollow structure and a production method thereof achieve a wide range of selections for users. The article is established with sufficient strength and durability, and is capable of achieving low cost and short delivery time. The article is configured by an outer shell having a hollow structure for forming an outer shape of a main body of the surfboard, a partition wall arranged within an internal space of the outer shell for connecting inner surfaces facing one another in said internal space, sectioned spaces separated and sealed by said partition wall and the inner surfaces of the outer shell, and a vent hole formed on said partition wall so that the sectioned spaces adjacent to one another can properly communicate with one another.

The invention relates to a method for producing a board-like gliding device (1), in connection with which strength-related and decorative layers (2, 3, 4) are joined together to form a one-piece composite body (6) in a hot compression molding cycle by means of a heated-platen compression molding device (5), whereby a cover layer (10) and/or a coating (11) of the gliding surface are selected from at least partly transparent plastic material, and the side (15) of the cover layer (10) and/or coating (11) of the gliding surface facing the core (9) of the composite body (6), is joined by means of a transparent adhesive layer (17) with a background layer (16) forming the visual background of the cover layer (10) and/or coating (11) of the gliding surface. Before the thin, variably shaped background layer (16) is introduced in the molding process, a layer (21) structured by recesses (22) and/or elevations (23) is secured on the side (20) of the background layer (16) to be facing the core (6), whereby by application of pressure and heat in the course of the process in which the layers (2, 3, 4) are joined, the surface structure (25) of the structured layer (21) is at least partly permanently transferred to the variably shaped background layer (16). Furthermore, the invention relates to a board-like gliding device (1) produced accordingly.
摘要:
A mold and construction method for forming aquatic sports boards is provided. The method and molds provide skin and interior core structures made shape-adjustable by a pre-molded perimeter rail. Division(s) in the structural exterior skin allow the skin core to be trimmed and bonded to a variety of convex, shape-defining core structures to produce a plurality of different shapes. A reusable shape-defining mold allows the board structure to be modified in shape. The mold is reversible and male/female configurations produce convex, shape-defining board substrates for a wide array of custom designs.

The invention relates to a method for manufacturing a gliding board (10), characterized in that it comprises the following distinct steps, which involve: manufacturing a foam preform (23) of core (24) by at least one shaping step by machining; proceeding with shaping the core (24) by thermoforming the foam preform (23) with material compression; covering the core (24) with an outer skin (26).

A surfboard includes a core covered with a laminate and having perforations where the user places his feet, in order to prevent air blisters from forming between the core and laminate. The core is formed from an extruded closed-cell polystyrene foam block which has been shaped by restraining it against a shaped form using shaped restraining tools and straps, and heating it; and by cutting using a hot wire. The core is laminated with FIBERGLAS® and epoxy resin, and the perforations are formed using a perforating tool that has a planar or curved working surface and one or more heated needles extending perpendicularly from the working surface.

A sailing or wave-riding board includes a foam core, a support layer, and a cover layer. The board has a number of incisions at least in portions of the surface of the support layer. The incisions increase the bending capacity of the support layer so that it can also be adapted to the contour in more curved areas of the foam core, in particular in a boundary area.
