Abstract
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.
