ABSTRACT
A mould can generally be defined as a pattern constructed for the production of the same shape of the prototype and the constructional material differs from one operation to another. When one considers the money at hand, he decides whether to start from the primary production hence or secondary production live. Every establishment starts from the small scale production level. Referring to this project, the main aim is for the establishment of small scale production and acaoid some problems that might arise during the cutting process. Since it is difficult for a poor man to adopt the mechanized method of soap production, this metal was constructed to enable him achieve his aim. In the construction of this project, a tablet soap mould was made which is capable of producing the standard sizes and shapes of soap required. In the construction work, wild steel was accessed, cut and assembled by welding in such a way that the whole assembly contains a cell. The cell is designed to produce the standard soap according to dimensions used in the construction work. Finally, after the construction process, the soap mould was produced.

INTRODUCTION
The equipment mostly used in the industries and manufacturing set-ups requiring the production of different patterns, shape and different designs, 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 he same type of the prototype. The constructional material differs from one operation to another. The need for the designing and development of moulds of different materials, composition, shapes, texture and corrosion resistance.
Moulds plays a very vital role in production industries. In the mechanical engineering set-ups, 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 moulds processes for their food production. Production of bread is usually a mould pattern process. This still applies to the other food items like sausages, roll, biscuits and others.
The metallurgical industries uses mould patterns for different casting operation and diverse application for the production of metal blocks, building blocks. Like in the production of both industrial and household plastic wares, moulds are used.
In the candle producing industries, moulds application is used for the process. This has resulted to the increase of activities in that section. In smaller mould production application, the building industries production of blocks, bricks and others.
With reference to the pharmacention companies where tablets of drugs of different size and texture are made, ninety percent (90%) of the tablet drugs were 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.
Conclusively, the costs of application of moulds in the solution to societal problems are in exhaustible and very relevant for the economic development of any nation.
The setting up of moulds manufacturing industry in the nation has a lot of implications. Thus, practice of importing most machines 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 spent in the importation of moulds different machines parts could be saved for the nation. Moreso, the mould industry will assist in producing high texture and corrosive resistance mould that would serve effectively rather then importing moulds that are not manufactured in consideration to the kind of Nigerian tropical environment.
In moulds industries, the different machines that are usually abandoned due to lack of spare parts are easily moulded and constructed since the material construction is known. The setting up of a mould industry would assist spreatly in harnessing the abundant metallic ore deposition in different parts of the country.
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.
In the construction of the soap mould, metal is used and metals, are generally the best material for construction because when the properties are improved by heat treatment and alloying, it would have little or no effects hence gives the optimum desire for construction.
Metallic moulds have the ability to conduct heat away from molten substance poured into it if the substance has some heat content it does not easily react with fluid poured into it and expands when it comes in contact with the heat from the molten substance.
However, metal was used for the construction of the soap mould because of its cost and availability.
