CONSTRUCTION OF A SIMPLE METALLIC MOULD

 

CHAPTER ONE

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.
