an extrusion molding apparatus for a product having a wood pattern and an extrusion molding method are disclosed , in which a second synthetic resin containing a wood powder of 80 ˜ 120 meshes at a predetermined ratio is fed to a die through a second extruder and then is coated on a surface of the product , thereby providing an esthetic surface and an improved durability . the extrusion molding apparatus is designed to successively produce a product having a wood pattern with a predetermined sectional shape by feeding a thermoplastic synthetic resin to an extruder and extruding the product through a die installed at an outlet of the extruder , wherein a second inlet is formed at one side of the die to fit a second synthetic resin thereinto , a second extruder which feeds the second synthetic resin is connected to the second inlet , and a second passage communicated with the second inlet of the die is formed to communicate with an original synthetic resin passage formed in the die , thereby coating the second synthetic resin on a surface of the product extruded from the die .
