A process and associated system for creating color effects using 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.
(canceled)
A stand-up paddle board comprising a sheet made of extrudable material including a plurality of viscous materials of different colors, the sheet being formed into at least a portion of the stand-up paddle board and having a surface presenting color effects resulting from partially mixing combinations of the plurality of viscous materials in amounts that vary along a longitudinal extent of the sheet to create a wave-like color gradation effect.
An extrudable material including a plurality of viscous materials of different colors, the plurality of viscous materials comprises:
An extruded material formable to make an article comprising materials of different colors and having a surface presenting color effects resulting from partially mixing combining the materials of different colors such that transversal sections of the extruded material normal to a longitudinal axis extending along the extruded material and distributed along the longitudinal axis of the extruded material are characterized by different amounts of the materials of different colors to create a wave-like color gradation effect, wherein the materials of different colors comprise a first material having a first viscosity and a second material having a second viscosity different from the first viscosity, and partially mixing the materials of different colors includes flowing the first material at a first rate of flow that varies over time and flowing the second material at a second rate of flow lower than the first rate of flow and the second rate of flow is kept substantially constant over time.
