Patent number: 6958185Abstract: A multilayer synthetic wood component comprised of a layer of a first synthetic wood composition that is secured to a layer of a second synthetic wood composition. As a result, the present invention may provide a component that utilizes the beneficial characteristics of each of the compositions. For instance, the component can have an improved combination of appearance, strength, durability, weight, weatherability, and other characteristics. Moreover, the present invention enables the ingredients of each layer to be tailored to the particular application. Consequently, certain ingredients can be conserved, thereby reducing the cost and/or the weight of the component.Type: GrantFiled: April 23, 2003Date of Patent: October 25, 2005Assignee: Crane Plastics Company LLCInventor: Burch E. Zehner

Publication number: 20040148965Abstract: The present invention relates to a system and method for directing a fluid through a die. One embodiment of the present invention is especially useful to thoroughly cool an extrudate by directing a cooling fluid toward a surface of the extrudate (e.g., an interior surface that defines a hollow portion of an extrudate). In another embodiment of the present invention, a fluid may be directed through a die for forming a layer or portion of a product. More particularly, a fluid may be directed through a die to form an external or core layer of a product from a foamed or unfoamed material including, but not limited to, a cellulosic-filled plastic composite. For example, the present invention includes a system and method for through the die foaming of extruded products.Type: ApplicationFiled: May 7, 2003Publication date: August 5, 2004Applicant: Crane Plastics Company LLCInventors: Herbert L.
