Our company production of car door hinge steel, is directly after the billet heating, through the mold rolling to make it formed, in recent years, in order to achieve customer expectations and quality improvement, after many times of research and demonstration, we have made three improvement measures for car door hinge steel.

1.After the billet is heated;A high pressure water dephosphorization process is added to remove the oxide scale produced by heating the billet to avoid cracking in the rolling process.

2.After the rolling molding is corrected, the milling machine is added to repair and grind the excess flicking, which not only solves the straightness of the steel, but also the accuracy of the dimension.

3.The hinge section steel packaging storage before the adoption of the shot blasting cleaning machine to increase the surface treatment process, used for hot rolling section steel after the scale and rust cleaning.
