1.) Milk cans need to have stainless steel sheets to perform cylindrical bending. Those round parts are welded in order to form a hollow cylindrical shape. The sheet thickness of milk can vary from 1 mm to 2 mm depending on the can volume.
2.) After the round bending operation, the part needs to have a cone shape and this cone shape is carried out by a rolling spinning machine for cold forming of sheet metals. The rolling spinning is a sheet metal forming operation used to form parts made from sheet metals into different geometries. In our case, the spinning rolling is performed by a PLC-controlled servo motor. Servo motors have high precision that helps to have a unique forming quality. Our spinning rolling machines are controlled by 2 servo motors, one of which controls the X-axis movement, the other Y, where there won’t be any change in the Z-axis.
3) After the spinning rolling machine, the part is taken to edge cutting and trimming to cut/trim the edges or bend/curl them inside/outside. These operations are needed to fix the upper part of a milk canister to the bottom part
4) After the rolling spinning and edge-cutting trimming operations, the milk can is taken to the polishing part to have a mirror effect on the inside and outside.

Plastic milk cans are lightweight and easy to handle, but they are not as durable as metal cans and are not suitable for high-temperature applications.
Stainless Steel for the Milk Can
Stainless steel milk cans are typically made from a type of austenitic stainless steel called 304 or 316. These grades of stainless steel are known for their excellent corrosion resistance, high ductility, and good formability. They are also non-reactive, which means they do not interact with the milk, ensuring the milk remains safe for consumption.
The manufacturing process for stainless steel milk cans typically involves sheet metal forming techniques such as deep drawing, bending, and welding. The sheet metal is first cut to size and then formed into the shape of the milk can using a deep drawing press. The top and bottom of the can are then formed separately and welded to the body of the can. The seams are then ground down and polished to give a smooth finish.
Aluminum milk cans are also made using sheet metal forming techniques, but they are generally less durable than stainless steel milk cans. Aluminum is a lightweight material that is easy to handle, but it is prone to corrosion and is not as strong as steel. Aluminum milk cans are typically made using the same manufacturing processes as stainless steel milk cans, but with different welding techniques that are better suited to the properties of aluminum.
Plastic milk cans are typically made using injection molding techniques. The plastic material is heated and injected into a mold that is shaped like a milk can. Once the plastic has cooled and solidified, the can is removed from the mold and any excess material is trimmed away. Plastic milk cans are lightweight and easy to handle, but they are not as durable as metal cans and are not suitable for high-temperature applications.
