Study Notes

Definition and Significance

Industrial materials and processes are essential components of Industrial Engineering, emphasizing material characteristics and transformation techniques.
Manufacturing serves as the backbone of industrialized nations, driving economic growth and development.

History of Materials

Stone Age (2.6 million years ago - 3300 BC):
- Early humans utilized stone, bone, and wood for tools and shelter.
- Oldowan tools represent the earliest known manufacturing (approximately 2.6 million years ago).
- The Acheulean hand axe (around 1.76 million years ago) indicates advanced skills.
- The Neolithic Revolution (around 10,000 BC) introduced agriculture and pottery innovations.
Copper and Bronze Age (3300 BC - 1200 BC):
- Metal smelting began with copper, followed by bronze for stronger tools and weapons.
- Ötzi the Iceman, preserved with a copper axe, illustrates early metal use.
- Bronze casting allowed for complex object creation and enhanced tools.
Iron Age (1200 BC - 500 AD):
- Introduction of iron smelting positioned iron as the primary material due to its strength and availability.
- The Iron Pillar of Delhi (around 400 AD) exemplifies ancient iron metallurgy and corrosion resistance.
Steel Age (1850s):
- The mid-19th century saw the invention of the Bessemer process, enabling steel mass production.
- Steel revolutionized industries, including construction and transportation, attributed to Henry Bessemer’s innovations.
Modern Age (Mid-20th Century - Present):
- Advanced materials like plastics, composites, and nanotechnology emerged.
- Plastics revolutionized material applications since the early 20th century.
- Composite materials combined various strengths for superior industrial performance.
- Nanotechnology allowed manipulation at atomic levels, leading to innovative materials and devices.

Material Processes

Material processes transform raw inputs into finished products, altering shape, properties, or appearance.
Primary Processes:
- Involve initial extraction and refinement of natural materials.
- Examples include mining, logging, and oil extraction.
Secondary Processes:
- Focus on transforming refined materials into semi-finished or finished goods.
- Key processes encompass:
  - Casting: Solidifying molten material in molds for complex shapes.
  - Machining: Cutting tools shape materials for precision.
  - Welding: Fusing materials through melting at interface points.
  - Heat Treatment: Modifying materials’ properties via controlled heating and cooling.

Types of Production Facilities

Food and Beverage Processing Plants:
- Transform raw agricultural products into consumable items through cleaning, sorting, processing, and packaging.
- Notable companies include:
  - Universal Robina Corporation (produces snacks and beverages).
  - San Miguel Corporation (produces beer and other food items).
  - Century Pacific Food, Inc. (specializes in canned seafood).
Electronics Assembly Plants:
- Focus on assembling electronic components using precision manufacturing techniques, such as surface mount technology (SMT).
- Texas Instruments Philippines, Inc. serves as a key example in this sector.
