Hot metal Section
  • Materials processing, the series of operations that transforms industrial materials from a raw-material state into finished parts or products.

  • Historically materials processing by hand is as old as mechanization which began with the Industrial Revolution of the 18th century principally in England.

  • Since then, metal processing methods, techniques have evolved, processes got faster, higher strengths steel can be achieved as well as different properties can be specified.

1.Casting Processes

The production of a metallic component is by casting of the molten metal into a mould. Most casting processes are used for the production of the initial metal ingot or near-finished shape (eg. I-beam) metals ready for the fabrication procedures.

Sand Casting:

  • Sand casting is characterized by using sand as the mould material.

  • Over 60% of all metal castings are produced via a sand casting process

  • Commonly used for hard but very brittle metals ( mainly for Aluminium Alloys)

  • Sand casting methods can have a very high quality of the completed product providing accurate dimensions to the finished surface of the metal.

2. Forging ( traditional hammering)

definition: manufacturing process involving the shaping of metals using localised compressive force (manual or mechanical)
