As shown in the figure, the purple cambered surface is used as the moving track for the arc arm, gear and other components after the installation as one unit. The position, concentricity and friction resistance of the cambered surface will affect the function of foldable hinge movement. (Total in length 158.94mm,Average thickness 0.34mm)

Molding and near net-shaping forming process: Such complex design could be guaranteed to its high-precision dimensions due to the high accuracy of the mold processing. The accuracy of mold with 0.005mm achieved is determined to the product quality with the precision of the product after forming is reached to 0.01mm.  With the continuously improvements & optimizations on the processing in the molding and forming,  such kind of complex product and strict G/T could be met with the customer’s dimensional & assembly requirements.
