2.Henan Signi speciality is in deep drawing quality . Grain size is tightly controlled to minimize
the "orange peel effect " , The "orange peel effect" is a rough surface,like the surface of an orange peel,
which often occurs after deep drawing. Signi tightly controls the chemistry and heat treating to
maximize the elongation that allow the materials to stretch more.
3.Henan Signi is a major aluminium circle producer of bottom plates , Signi has been producing impact bonded bottom plates in high volumnes for more than 10 years.
