Fabrication Of Candle Mould With Twenty Four (24) Holes

The candle mould has twenty four (24) holes which could produce twenty four (24) quality candle sticks

Aluminum, a non ferrous metal was used as the construction material for the mould the type of casting technique used was green sand mould method.

In the process of moulding the pattern was placed in the flask which contained the green sand.  The flask was turned upside down and the reverse side of the pattern was formed.  This part is called the positive part, the other part of the pattern formed on the moist sand is called the negative part, the two parts were then joint together to form the cope and the drag.

A gate or opening was provided for the pouring of the molten aluminum into the mould.  Gases and fumes were able to escape through the vents.

It was ensured that the molten aluminum filled all parts of the mould with the least delay.  All part of the candle mould  were machined after casting to get a perfect exterior and interior surface finish.

The fabrication  of the   candle mould cost seven thousand (N7,000) naira for both material and labour.
