Raw materials are natural resources (wood, cotton...).
Raw materials are transformed into manufactured products in factories.
This is called the industrial process.
Many people work in factories where they specialise in one job.
They design or make parts of different products.
Factory workers often work on assembly lines.
Each worker makes only one part of a product, then passes it on to another worker.

Assembly line.
