(3) lids, cans were sealed volume, the shape and the size of each part to meet certain requirements.

It is known that double seaming seal structure is spliced ​​metal to metal, metal to metal splicing it is impossible to achieve absolute seal, because the thickness of the metal substrate, strictly speaking, is not uniform. For three cans, side seams are uneven, and sealing equipment is in constant wear, in order to seal in double seaming must have a layer of sealing compound to fill the above causes of leakage channel.

Metal cans seaming is usually done by a two-step operation. The flange portion of the first operation of the can lid pressed into crimp section formed interlocking structure. Second operation will first operation interlocking structure formed pinch complete seaming. Since the seaming operation is completed by two steps, so named after the double seaming, also known as double seaming.
