[0002] The end cap is a component used to seal the end of a container to isolate the media inside and outside it, also known as an end cap. The end caps of cylindrical containers are generally rotating shells. 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. Some gas cylinders use a combined bottom end cap with the convex surface facing inward, which can ensure strength and meet the needs of safe use. The end cap is an indispensable and important component of pressure vessel equipment in many industries from petrochemicals, atomic energy to food and pharmaceuticals. When preparing large thin-walled end caps, large-size stamping machines are required for molding.
