The end cap of a cylindrical container is generally a rotating shell. According to the shape of the end cap surface, it can be divided into convex, conical, flat and combined shapes. A convex end cap refers to a end cap with a convex outer surface, such as a hemispherical, elliptical, dished and spherical end cap without folded edges. The butterfly head is also called the spherical head with folded edge, also known as the butterfly head. It consists of a spherical surface, a cylindrical straight edge of a certain height and a transition part connecting the above two parts with a curvature radius smaller than the radius of the spherical surface. The butterfly head needs to go through stamping, stretching and other steps during production and processing.
