摘要： Disclosed herein are a method of manufacturing a wood plastic composite panel, including a panel manufacturing process of extruding and cooling a resin complex, such that wood fiber is uniformly dispersed into a synthetic resin matrix, to manufacture the resin complex into the form of a panel, an embossing process of forming a wood pattern corresponding to the cut-open surface of a natural lumber on the surface of the panel to a predetermined depth, and a brushing process of removing some of a synthetic resin layer from the surface of the panel to form linear micro concavo-convex parts to a predetermined depth, and an apparatus for manufacturing a wood plastic composite panel that is capable of efficiently performing the same. The method of manufacturing a wood plastic composite panel according to the present invention has the effect of directly realizing a wood pattern, which has the appearance and the texture similar to the open-cut surface of a natural lumber, on the surface of the wood plastic composite panel, and, at the same time, maximizing the advantage of the material comprising the wood fiber and the synthetic resin.

摘要： Disclosed herein is a solid-state extrusion-orientation process. The process produces a polymer-oriented profile by compressing a billet through an extrusion die, in which the billet comprises crystalline or semi-crystalline polymers or a composite containing the polymers and an organic or inorganic filler. The process comprises the steps of preheating a pressure chamber to a temperature of a polymer's melting point or less, applying ultrasound to the extrusion die positioned next to the pressure chamber and having a smaller cross-sectional area that the pressure chamber, and extruding the billet through the pressure chamber and the extrusion die to produce the polymer-oriented profile. This process eliminates the step of heating the extrusion die, thereby ensuring convenient and rapid operation while providing a polymer profile having a smooth surface without any defects.
