INTRODUCTION

3
 INTRODUCTION
FOUNDRY
A Foundry is a factory that produces metal casting
metals are cast in to shapes by melting them in to a liquid,
poring the metal in to mold and removing the mold material
after the metal has solidified as it cools. The common metals
processed are aluminum and cast iron.

4
TYPES OF PATTERN

5
 TYPES OF PATTERN

➢ Two piece pattern

➢ Multi piece pattern
➢ Match plate pattern
➢ Gate pattern
➢ Sweep pattern
➢ Skeleton pattern
➢ Loose piece pattern

6
TOOLS USED IN FOUNDRY

7
 TOOLS USED IN FOUNDRY

➢ Hand riddle
➢ Shovel
➢ Rammers
➢ Sprue pin
➢ Strike off bar
➢ Mallet
➢ Draw spike
➢ Vent rod
➢ Trowels
➢ Gate cutter
➢ Bellows
➢ Swab

HAND RIDDLE

Hand riddle consists of a screen of standard circular wire

mesh equipped with circular wooden frame .even power
operated riddles are available for riddling large volume of
sand.
8
SHOVEL

Shovel consists of an steel pan fitted with a long wooden

handle. It is used in mixing, tempering and conditioning the
foundry sand by hand

RAMMERS

Rammers are required for striking the moulding sand mass

In the moulding box to pack or compact it uniformly all
around the pattern. The common forms of rammers used in
ramming are hand rammer, peen rammer, floor rammer and
pneumatic rammer.

SPRUE PIN

Sprue pin is a tapered rod of wood or iron which is placed or

pushed in cope to join mould cavity while the moulding sand
in the cope is being rammed. Later its withdrawal from a
cope produce a vertical hole in moulding sand, called sprue
pin.

9
STRIKE OFF BAR

Strike off bar is a flat bar having straight edge and is made
of wood or iron. It is used to strike off or remove the excess
sand from the top of a molding box after completion of
ramming thereby making its surface plane and smooth.

LIFTERS

Lifters are also known as cleaners or finishing tool which are

made of thin sections of various length and width with one
bent at right angle. They are used for cleaning, repairing and
finishing the bottom and side of deep and narrow openings
in mold cavity after withdrawal of pattern. They are also
used for removing loose sand from mold cavity.

SMOOTHERS

According to their use and shape they are given different

names. They are also known as finishing tools which are
commonly used for repairing and finishing and round
surface, round or square corners and edges of molds.

10
GATE CUTTER

Gate cutter is a small shaped piece of sheet metal commonly

used to cut runners and feeding gates for connecting sprue
hole with the mold cavity.

BELLOWS

Bellows gun is hand operated leather made device equipped

with compressed air jet to blow or pump air when operated.

11
PROCESS IN FOUNDRY

12
 PROCESS IN FOUNDRY

PATTERN MAKING
A pattern maker interprets a design by drafting it through
pattern pieces as per the body measurement following a set
of instruction in order to create a style. The process is called
pattern drafting.

MOLDING

Molding is a manufacturing process that involves shaping a

liquid or malleable raw materials by using a fixed frame. It
is known as either a mould or a matrix. It is called molding.

MELTING

The most common melting method is used in foundries is

induction melting. In this technique, heat is generated in the
metal charge by inducted currents resulting from the
magnetic field established in the furnace by a coil
surrounding the furnace.

13
POURING

Pouring process are recycled scrap metal is melted into a

liquid within a smoldering hot furnace. Its resulting contents
are poured into a lade, from which it is then transferred into
moulds.

CLEANING

Shot blasters are used in the first stage of cleaning. In these

systems, steel balls or small iron stars are shot at the casting
by an impellor. They strip off scale flashing burrs and other
impurities. Air blast machines can also use a smaller
abrasive.

INSPECTION

When the foundry chooses samples and submits them to

destructive testing, the metal properties are closely inspected
after the casting is cut.

14
MELTING OF RAW MATERIAL

15
 MELTING OF RAW MATERIAL

Raw material is important element in any foundry. The raw

material used, contributes a lot for the energy consumed in
any foundry. The melting energy takes its important role in
consumption and so effective management in this direction
is much essential. Apart from this, the other energies which
take lead roles are energy intensive systems such as
compressed air and transport systems for molten metal and
so on.

These contribute their part in adding the content of energy in

the casting. The energy needed for getting a high quality
product in a foundry depends on two important facts. They
are total energies consumed in the foundry and the quantity
of castings shipped.

16
PREPARATION OF MOULDING SAND

17
 PREPARATION OF MOULDING SAND

The important properties that molding sands for green sand

molds should generally have are that by using the molding
sands the green sand molds can be readily formed, and that
molten metals having a high temperature can be
satisfactorily poured into the green sand molds that have
been prepared by using the molding sands without the
molten metals being disadvantageously affected. The former
is a property that is described as a mold ability of molding
sands at ordinary temperatures. On the other hand, the latter
is a property of molding sands at high temperatures. To make
a mold, first a molding sand must be adapted to a pattern to
exactly copy it. Then, after the mold is made, the pattern is
drawn out from the mold.

18
CASTING OF MOLTEN METAL

19
 CASTING OF MOLTEN METAL

Today, nearly every mechanical device we use, from

automobiles to washing machines are manufactured using
metal parts that were created using the casting process. The
difference between today’s cast metal products and those
that were manufactured even 100 years ago is the precision
and tolerances that can be achieved through the
computerized automated design process, and modern
methods for producing the detailed cores and molds.
Modern-day metal casting represents innovation at work.
Throughout the centuries, various combinations of raw
materials have been developed to produce various metal
types. Some cast products are used in engines that require a
high tolerance for heat and cold.

20
REMOVAL OF EXCESS MATERIAL

21
 REMOVAL OF EXCESS MATERIAL

All excess material which has been stockpiled at the work

site, and which will not be used for backfill or other fill
purposes, shall be removed from the project area within 48
hours of the excavation. In all cases, stockpiles of all
excavated material and all construction materials shall be of
limited size and shall be neatly maintained in such a manner
that they will not block existing drainage or be hazardous to
pedestrian or vehicular traffic in any way. The limitation
relative to the stockpiling of all excavated material and all
construction materials shall be controlled by the Owner and
the City.

22
FINISHING AND POLISHING

23
 FINISHING AND POLISHING

The finishing and polishing stage for investment cast

products is crucial. Different industries have differing
polishing and finishing requirements, largely dependant on
the application or production needs. From agricultural
applications to the food preparation industry, choose a
company keen on the final details with R2 Quality Castings.
We offer custom polish and finishing services for various
industries and applications as a value added service for
investment cast products. Our product finishers are
knowledgeable in the various polishing requirements, and
can buff material to your exact specifications. Ensuring your
final result meets and exceeds expectations.

CONCLUSION

25
 CONCLUSION

We would like to say this training program is an excellent

opportunity for us to get to ground level and experience
the things that we would have never gained through going
straight into a job we are grateful to the VEEYES
FOUNDRY for giving us this wonderful opportunity.

The main objective of the internship is to provide

an opportunity to undergraduate to identify, observe and
practice how mechanical Engineering is applicable and
the real site it is not only to get experience on technical
practices but also to observe management practices and
to interact with the field workers. The only chance that an
undergraduate has to have this experience in the industrial
training period.
