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.

An extrusion molding method for successively producing 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, the extrusion molding method comprising the steps of:
A product having a wood pattern characterized in that a second synthetic resin is formed on an outer surface of the product produced by extrusion molding, at different ratios depending on positions.
An extrusion molding die for a product having a wood pattern, provided with a thermoplastic synthetic resin and a synthetic resin passage, the thermoplastic synthetic resin being installed at an outlet of an extruder so that it is to be fed to the extruder and then extruded in the product having a predetermined sectional shape such as the synthetic resin passage, the extrusion molding die characterized in that a second inlet is formed at one side of the die to fed a second synthetic resin thereto, and the second inlet is formed to communicate with a second passage communicated with the synthetic resin passage of the die so that the second synthetic resin is coated on a surface of the product extruded from the die.
