Team “2” Presented to: Dr. Mohamed AbdEl - Monem Daha CAN MANUFACTURING
HISTORY OF CAN MANUFACTURING
• Early tin cans were sealed by soldering with a tin-lead alloy, which could lead to lead poisoning.
• Use of aluminum in cans began after the (2nd
world war) in 1957.
Why Aluminum?
• Less in cost.
• Greater malleability.
• This gave rise to the two-piece can, where all but the top of the can is simply stamped out of a single piece of aluminum, rather than constructed from two pieces of steel.

Impact-extruded aluminum cans necked-in to accept the valve cup.
No welding is used.
Often used for sprays and paints.

Mostly used as beverage cans.
They have many ends like easy-open end.
They may contain another contents like car-wax and shoe polisher.
TWO-PIECE CANS
The Aluminum can consists of:
97.4% Aluminum
1% Magnesium
1% Manganese
0.4% Iron
0.2% Silicon
MATERIALS OF BEVERAGE CAN
Team "2" 12
Draw (Shallow Draw): Shallow-profile cans(whose height is less than their diameter.
Draw and redraw (DRD): shallow drawing in 3 steps.
Draw and iron (D&I ): Carbonated beverage cans.

• Requires more material.
• Reduces top-to-bottom compression strength.
• Complicates labeling.
SIDEWALL BEADING & CAN END SHELLS
(1) Cutting the blank
(2) Redrawing the cup
(3) Trimming the ears
(4)Cleaning and decorating
(5) The lid
(6) Detecting and quality assurance
(7) Filling and seaming

(6) Detecting and quality assurance using duplex seam micrometer.
A TWO-PIECE (BEVERAGE) CAN PROCEDURES
They are made of Tin-plated or tin-free steel depending on the end use.
Used for paints containers, glues, and aerosols.

• The manufacturing process for aluminum beverage cans is already technologically very advanced, and therefore it is useful to have the utmost information possible on material and tooling, in order to optimize it
