5. • A pattern may be defined as a replica model of the desired casting
which, when packed or embedded in a suitable molding material,
produces a cavity called MOULD. This cavity, when filled with a
molten metal, produces the desired casting after solidification of the
poured metal
• Material For Pattern
1. Wood
2. Metal
3. Plaster
4. Plastics
5. Wax
5. Wax

6.  In this process, a liquid
material is usually poured
into a mould, which
contains a hollow cavity of
the desired shape, and then
allowed to solidify.

7.  A foundry is a place in an industry,
where the moulds are prepared with
the help of different types of
things(such as sand, bentonite, fire
clay, dextrine etc.) and poured them
with molten metal to get the solid
casting which can be used for specific
purposes after machining with in
specified limits and dimensions.

14. • The process of Heat Treatment involves heating of solid metals to specified
temperatures holding them at that temperature and then cooling them at
suitable rates in order to enable the metal to acquire the desired properties to
the required extents.
• To change the properties of the metal or to get the required properties with
the help of heat as per design.
1. To relieve internal stresses.
2. To improve mechanical properties.
3. To improve machinability.
4. To change the internal structure.

15. The section is primarily concerned with the manufacturer of small parts
of machine tools. The section is further divided into six subsections.
Spindle Section
Gear Section Non Round Section Sheet Metal Section
Turret SectionRound Section

16.  It is the shop which gives the
shape to the largest castings which
comes from the foundry shop after
being painted rough.

These are generally manually worked machines involving no
computerized or numerical control. These are semiautomatic in
nature. Following machines are manufactured in GPM assembly
