    摘要： Disclosed is a method of manufacturing a connecting rod by using semi-closed sinter forging. The method includes: a first step of positioning a metal powder of a sintering material in a closed mold and then forming a preliminary formed body by using a general forming press; a second step of heating the formed preliminary formed body to sinter the preliminary formed body; a third step of semi-closed forging the sintered preliminary formed body to manufacture a forged part; a fourth step of cooling the manufactured forged part to normal temperature; a fifth step of removing a flash from the cooled forged part through a punching process; and a sixth step of manufacturing the connecting rod through a shot blast treatment in order to remove a foreign substance existing on a surface of the forged part from which the flash is removed.

    摘要： Disclosed is a polypropylene resin composition and interior and exterior materials for vehicles using the same, particularly an olefin-based polypropylene resin composition including: about 50 to 70% by weight of a high crystalline polypropylene; about 10 to 20% by weight of a reactor made thermoplastic polyolefin (RTPO) polypropylene; about 5 to 20% by weight of an inorganic filler; about 10 to 20% by weight of a rubber elastomer; and about 3% by weight or less of a slip agent, based on the total weight of the composition. The composition provides excellent physical properties such as high strength and impact resistance, and thus superior resistance to damage, and shows low gloss characteristics and excellent fluidity.
