  • Aluminum Smelting From Bauxite Ore
    Aluminum is one of the most used metals in today’s industry, having properties of strength, durability, conductivity, lightness, and corrosion resistance. Alumina, processed from the mined bauxite ore, is fed into a cell where it is mixed with cryolite, through which a DC electric current is passed.
  • Guide to Steel Making Processes and Technology
    Steel provides life to the designs of humanity. It has remained an invincible metal through the centuries, but how is it refined, and recycled? What is the difference between cast iron and stainless, and what are the primary alloys of steel?
  • History of Automation in Manufacturing
    The history of automation in the manufacturing industry can be traced back to the early use of basic pneumatic and hydraulic systems, up to the modern robots used by industry today. Many operations in the manufacturing industry have become automated, increasing production at the expense of labor.
