The shaping and forming processes involved in manufacturing the body of a milk powder can typically include the following:

Sheet Cutting: The first step involves cutting sheets of metal into the desired size and shape to form the cylindrical body of the can. This may be done using shearing machines or laser cutting technology.

Cupping: The cut metal sheets are then fed into cupping machines where they are formed into shallow cups or blanks. This process involves the application of pressure to push the metal into a cup-shaped form.

Drawing: The cupped blanks are further shaped and elongated through drawing processes. Drawing involves pulling the cupped blanks through a series of dies to gradually stretch and shape them into longer, narrower forms resembling the shape of a can.

Ironing: In this process, the drawn blanks are passed through ironing machines where they are elongated and thinned to achieve the final desired thickness and shape. Ironing helps in improving the dimensional accuracy and surface finish of the can body.

Necking: Some milk powder cans may require a necking process to form the narrower neck portion of the can. Necking involves reducing the diameter of the can body at one end to create a neck or opening for sealing with a lid.

Flanging: Flanging is the process of forming a flange or rim at the open end of the can body. This flange provides a surface for attaching the lid or closure to seal the can.

Seam Welding: Finally, the side seam of the can body is welded together to form a continuous cylindrical structure. This can be done using various welding techniques such as resistance welding or laser welding, depending on the material and thickness of the can.

These processes may vary slightly depending on the specific design requirements and production methods used by different manufacturers. However, these are the fundamental steps involved in shaping and forming the body of a milk powder can from raw metal sheets.
