Method for manufacturing interior parts for vehicle using real material

A method of manufacturing an interior component for a vehicle using a real material, the method comprising:

• bonding a plurality of laminated printed layers on a rear surface of the real material;
• injection-molding an injection-molded product by putting the real material into a molding mold to form a shape;
• laminating the real material on the injection-molded product, wherein the injection molded product has a shape corresponding to the formed shape of the real material;
• forming a light-transmitting part that defines a symbol part on a front surface of the real material, the light-transmitting part protruding in a shape of the symbol part;
• mounting a light source unit on the injection-molded product, the light source unit being configured to be selectively lighted through the light-transmitting part in response to detecting a change in a capacitance from the front surface of the real material;
• attaching a film on which the symbol part is printed to the front surface of the real material;
• performing laser processing along a shape of the symbol part printed on the front surface of the film so that a light-transmitting region is formed in the real material;
• supplying a resin to the light-transmitting region by injecting the resin into the light-transmitting region through a supply flow path connected to the light-transmitting region;
• curing the resin by irradiating ultraviolet rays to the film including the light-transmitting region;
• and
• removing the film from the real material.

A method of manufacturing an interior component for a vehicle using a real material, comprising:

• bonding a plurality of laminated printed layers on a rear surface of the real material, the plurality of laminated printed layers including a non-woven fabric and a thermoplastic polyurethane (TPU);
• injection-molding an injection-molded product by putting the real material into a molding mold and laminating the real material on the injection-molded product injection-molded in a shape corresponding to a processed shape of the real material;
• and
• forming a light-transmitting part that defines a symbol part on a front surface of the real material, the light-transmitting part protruding in a shape of the symbol part;
