Construction of a simple
metallic mould
CHAPTER ONE
1.0
INTRODUCTION
The equipment mostly used in the
industries and manufacturing establishments requires the production of definite
shape, pattern, different design, embossments and others, are usually
moulds. The ability of moulds to withstand pressure, distortion and corrosion
determines the application.
A mould has been defined as a
pattern constructed for the production of the same type of the prototype.
The constructional material differs from one operation to another. The
diversity of the application gives the need for the designing and development
of moulds of different materials, compositions, shapes, textures and crossing
resistances.
Mould is as old as man, the early
days of the blacksmiths were able to construct, design materials of different
shapes and sizes using mould.
1.1
USES OF MOULDS IN PRODUCTION INDUSTRIES.
-
The metallurgical Industries use mould pattern for different casting operations
and diverse application for the productions of metal blocks, building blocks,
e.t.c like in the production of both industrial and household plastic wares.
-
In the manufacturing set –up, the different types of accessories that have
different profiles are usually produced using moulds.
-
In the mechanical engineering set-up, moulds are
usually used for the production of different machines parts with intricate
shapes that cannot be easily manufactured on a lathe.
-
The food industry applies for moulds processes for
their production. Production of bread is usually a mould patterns
process. The still applies to the other foods items like Biscuits,
sausage rolls, cakes and others.
-
In pharmaceutical companies where tablet drugs of
different sizes and textures are made, ninety – percent (90%) of the tablet drugs
are produced in moulds.
-
The electrical components – manufacturing
industries utilize moulds for the different production of accessories and
fittings used in the household and commercial lighting activities
-
In the candle producing and making industries mould
application is for the processes.
This has resulted to the increase
of activities in that section. In smaller mould production application,
the building industry makes use of mould system in the production of blocks,
bricks and others.
Conclusively, the costs of
applications of moulds. In the solution of society problems are
inexhaustible and very relevant for economic development of any nation.
1.2
IMPORTANCE OF MOULD MANUFACTURING
INDUSTRIES TO THE NATION.
The setting up of mould
manufacturing industry in the nation has a lot of implications. Thus
practice of importing most machine parts from the overseas have really rendered
the action of setting up moulds making industries useless. The economic
implications of mould industries are discussed below.
-
The high foreign exchange cost in the importation
of moulds and different machines parts could be saved for the nation.
-
The mould industry will assit in producing high
texture and corrosive resistant mould that would serve effectively rather than
importing moulds that are not manufactured in consideration to the tropical
kind of Nigeria environment.
-
In mould industries, the different machines that
are usually abandoned due to lack of spare pars are easily moulded and
constructed since the material construction is known.
-
The setting-up of mould factory would assist
greatly in harnessing the abundant metallic ore deposition in different
parts of our country.
-
The mould industry would definitely lead to
industrial and commercial growth, since the diverse operations that are usually
projected by mould formation would begin to thrive.
-
Conclusively, setting up of mould producing
industries will have a positive effect on all facets of projects associated
with lack of spare parts and accessories.
