A blanking head is a component used to seal the ends of containers to isolate the internal and external media, also known as an end cover. The blanking heads for cylindrical containers are typically rotationally formed. They can be classified by the shape of their surface into convex, conical, flat, and composite types. A convex blanking head refers to a head with an outer surface that is convex, such as hemispherical, elliptical, dish-shaped, and seamless spherical heads. Some gas cylinders use a composite bottom blanking head with the convex surface facing inward, which ensures strength while also meeting safety requirements.
