What is the difference between fabrication and processing


Definition and Overview

Definition of Fabrication

Fabrication refers to the act of making a product from raw or semi-finished materials rather than from ready-made components. This can often involve cutting, shaping, and assembling various parts to create a finished product or part of a larger system.

  • Types of fabrication methods
    • Cutting: This is the process where large sheets or structures of metal are split into smaller pieces using methods such as laser cutting, plasma cutting, or water jet cutting.
    • Folding: Used primarily for metals, folding changes the metal’s direction without cutting or removing any material.
    • Welding: This method involves joining two metal pieces together using heat or pressure.
    • Machining: A process where material is removed from a workpiece to shape it. Common methods include turning, milling, and drilling.
  • Common examples in industries
    • Construction: The creation of structural steel components.
    • Automotive: Fabrication of parts like the chassis or body panels.
    • Electronics: Production of metal casings or enclosures.

Definition of Processing

Processing encompasses a series of methods employed to transform raw materials into finished products. While it can refer to any kind of refinement, it’s most commonly associated with food, minerals, and materials.

  • Different processing techniques
    • Mechanical processing: This can include grinding, milling, and other forms of physical alteration.
    • Thermal processing: Methods such as heat treatment or cold treatment to change the properties of materials.
    • Chemical processing: Involves using chemicals or biochemical means to change material properties.
  • Role of processing in manufacturing
    • Quality improvement: Processing can help enhance the quality of materials, making them suitable for specific applications.
    • Consistency: Ensures a standard of uniformity across batches of products.
    • Safety: Particularly in the food industry, processing can eliminate contaminants or pathogens, making products safe for consumption.


Key Differences

Purpose and Goal

Fabrication and processing serve different core objectives in the world of materials and products.
