2. BLANKING PROCESS
• Blanking is a stamping process
in which a mold is used to
separate a portion of a sheet
from another portion along a
certain contour shape. Blanking
is the process of using a mold to
separate the sheets.

3. TECHNOLOGY
USED
• A machine mechanism (crank slider)
is used.
• Power press stamping machine
(tonnage of machine depends on the
cutting force required)
• An automatic feeder is used to transfer
coils of sheet metal into a blanking
die.

4. THE BLANKING
PROCESS
PARAMETER
•
• Raw material/strip
• Dimension
• Appearance- visual
inspection

5. ADVANTAGES AND DISADVANTAGES OF
BLANKING PROCESS
ADVANTAGES DISADVANTAGE
 Piece part is accurate, and shapes can
be formed neatly.
 Higher equipment costs, due to bigger
blanking die and machine.
 Metal remains flat and does not bend
in the process.
• Machine are large ang take up a lot of
space in factory.
 Detail can be added and punch shape
can be changed.
• Machine are bad for environment as they
are high powered and required a lot of
energy to work efficiently.

6. POSSIBLE DEFECTs IN BLANKING
PROCESS
They include
burrs,
Fracture, Burnishing, Dented.

7. DEEP DRAWING PROCESS

8. DEEP DRAWING
DEFINITION
• Deep drawing is a metal
forming process for creating
seamless, sheet metal parts
that are closed on one end
and have a depth greater
than their radius. Deep
drawn parts achieve their
shape by drawing metal into
a cavity rather than by
stretching or thinning over a
die

9. TECHNOLOGY USED

10. MECHANISME
• 1.Vacuum suction cup auto feeding is
used for loading/unloading the
workpiece(product)- Control by
pneumatic system.
2.Finish part from this station
transferred by belt conveyor and
ready for the next station.

11. DEEP DRAWING
PROCESS
PARAMETER
 Dimension of dome
(extra 10% from
actual height for
trimming process)
 Surface quality (Visual
Inspection-
appearance)

12. ADVANTAGES
OF DEEP
DRAWING
 No Seams: Deep drawing produces shapes that are
uniform and seamless, reducing potential weak points
in the finished part.
 Uniformity: Deep drawn parts have a high degree of
consistency from the start of a production run to the
end.
 Rapid Cycle Time: Presses set up for deep drawing can
be cycled quickly, making this a very efficient way to
produce large quantities of parts.
 Faster Assembly: Deep drawing can create shapes with
a closed end, reducing or eliminating the need for
fabrication or welding as secondary processes.

13. DISADVANTAGES OF
DEEP DRAWING
• Deep drawing is ineffective in little volumes.
Short-run deep drawing is more expensive
since press setup is expensive and takes
knowledge.
Deep drawn manufacture is cost-effective with
a minimum order number in the hundreds.
• Deep drawing's formability limits some
industrial usage.
Radial drawing stress and tangential
compressive stress can cause wrinkling,
fracture, and breaking.

15. WELDING
&
HEAT TREATMENT
PROCESS

16. SEAM AND SURMERGED ARC WELDING
PROCESS
• Seam Welding is the joining of work pieces made of similar or dissimilar
materials along a continuous seam where Submerged Arc Welding is
common arc welding process that involves the formation of an arc between
a continuously fed electrode and the workpiece.
• Both of this process commonly used in industry to weld pressure vessel
such as boiler and cylinder gas.

17. SEAM WELDING USED IN MANUFACTURE OF
LPG CYLINDER

18. EXPLAINATION
• In the production of LPG cylinders,seam welding is an important part of
connecting the top and bottom shell
• Generally below 40 L LPG bottle,40 L above has a three-piece
design,consists of top and bottom of shell and cylindrical envelope

19. PART AND TYPES OF LPG CYLINDER BODY

20. (S.A.W) USED IN
MANUFACTURE OF
LPG CYLINDER
The welding
automat holds the
upper and lower
cylinder halves
horizontally and
rotates them for the
fixed welding head
to weld

21. ADVANTAGES AND DISADVANTAGES OF SEAM
AND (S.A.W)

22. POSSIBLE DEFECT
• Submerged arc welding produces a risk of solidification cracking as a
result of deep penetration and considerable melting of the workpiece
material which causes substances from the workpiece material to end up in
the weld metal

23. HEAT TREATMENT
• Heat treatment is the process of heating metal without letting it reach its
molten or melting stage and then cooling the metal in a controlled way to
select desired mechanical properties
• Commonly there are 4 types of heat treatment process that is
Annealing,Normalizing,Quenching and Tempering.

24. ANNEALING
• Annealing is the process of heating the metal to 600 ºC-640 ºC until its
reach the austhenite state and then cooling the metal with slow cooling
rate in a furnace.
• The purpose of annealing is to improve the ductility of the metal and
reduce its brittleness

25. ANNEALING PROCESS APPLIED ON LPG
CYLINDER

26. EXPLAINATION
• The cylinder gas pass through the oven from entry to exit side on the
conveying system for the proper heat treatment process with
preheating,heating and cooling steps.The total heating time is 20-38s.
• The oven has entry,heating zone,heat holding zone,cooling zone and
exit sections.
• Diameter of the cylinder gas is 300-330 mm and the height is 575-640
mm,cylinders are transferred in vertical into the oven (furnace).

27. NATURAL GAS HEAT TREATMENT IN
FURNACE
• ADVANTAGE
- Improve safety and quality of each cylinder
• DISADVANTAGE
-Chemical gases released into the air can be harmful and affect our health
• POSSIBLE DEFECT
-Distortion/Sagging,when high temperature treatments are applied to
vulnerable thin-wall vessels large,heavy component

28. POSSIBLE DEFECT
• Distortion/Sagging,when high temperature treatments are applied to
vulnerable thin-wall vessels large,heavy component
DISTORTION
