introduction
Sophisticated tools and knowledge of various control technologies (mechanical, electronic / computer, pneumatic) are needed to design and manufacture any product. This is just as true of a factory that produces chocolate as one that produces mobile phones or cars.
For example, Cadbury Creme Eggs used to be individually wrapped and the process was labour-intensive. Fully automatic egg machines now mean that a series of mechanical operations have replaced human handling. This means quicker production time and fewer blemishes on the product.
