Construction Of Soap Moulds, Table And Cutters

Project and Seminar Material for Chemical Engineering

Abstract

A mould can generally be defined as a pattern constructed for the production of the same shape and size. 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 level or secondary production level. Referring to the project, the aim is for the establishment of small-scale production. This would employ the use of the manual soap cutters, which is either used to cut the soap produced into bars or tablets depending on specification.

In the construction works flat hard woods of 20m thickness were cut and assembled by nailing. The constructed woulds have the following dimensions : 15cm long, 38cm wide and 15cm high.

The moulds are rectangular in shape. Handles was incorporated in the mould to make it convenient to be carried about during soap production.

Finally, the five moulds produced were capable of presenting relatively resistance to impact and bending forces as a result of the hard wood that was used. With this the moulds can carry a reasonable volume of soap Surry without collapsing.

Introduction

The equipment mostly used or applied in the industries and manufacturing setups requiring the production of definite patterns, shapes and different designs, embossments and others, are usually moulds.

The moulds used for the numerous types of plastic and the several types of moulding methods in commercial use constitute a controlling factor in the molding industry. The most advantageous utilization of both plastic and molding equipment requiring a properly designed and constructed mould.

The application of moulds depends on its ability to withstand pressure, corrosion and distortion.

Mould can be defined as a pattern constructed for the manufacture of the same protype. The material of construction of moulds varies from one operation to another. The need for the designing and development of moulds of different materials, composition, texture, shape, resistance arises as a result of the diverse application of moulds in manufacturing industries.

Early moulds were used by blacksmiths in construction and designing materials of different shapes and sizes. Moulds basically consists of a cavity and a plunger, or force. Most moulds also include an ejection mechanism for removing the moulded article.
