PKG 221 METAL SIMULATION MIDTERM EXAM
2026 QUESTIONS AND SOLUTIONS
GUARANTEED TO PASS
◉ Disadvantages of Metal. Answer: Cost of setting up Production is
high
It is not a flexible process considering size
◉ What were cans originally made of? How were they held together?
Answer: Originally made of tinplate by hand. All ends were soldered.
◉ The two piece can produced by. Answer: Drawing and Ironing, made
use of aluminum possible which cannot be soldered or welded. D&I
lowers cost of can production. Cans used to be produced at 10 per min
now 2500 per min
◉ Necking in. Answer: Reducing the diameter of the top of the can,
savings.
◉ Steel Temper Classifications. Answer: Designated by an arbitrary
number on the Rockwell 30 T Hardness tester. Measures penetration of
steel ball into sheet surface at given force.
, ◉ Temper and Hardness. Answer: Effected by rolling and annealing.
Work hardened=rolled when cold(much stiffer). Double reduced=rolled
once, annealed and the cold rolled again (max stiffness).
◉ Steel in the form of low carbon steel is known as?? Answer:
blackplate, which is then converted into tinplate or tin free steel.
◉ Tinplate. Answer: Produced by electroplating blackplate (coated on
both sides). Tin provides good corrosion resistance. Organic coating
inside helps avoid metal taste.
◉ BPA. Answer: Used in plastic containers, and metal can liners. Linked
to health problems, but FDA declined to regulate BPA.
◉ Aluminum. Answer: Bauxite= aluminum ore. Very abundant.
Lightweight (1/3) of steel. Odorless and tasteless.
◉ Aluminum Rigid and Flexible Applications. Answer: Rigid- Beer/Pop
cans, trays, tubes
Flexible- Foil, metalized film
◉ Tin. Answer: Primary use is for tinplate, non-toxic, reduces rate of
corrosion in steel cans. Soldered for side seams of non food cans
(sometimes?.). Very expensive. Hard to obtain. Only about .000015
inches thick.
