Fabrication creates objects from raw materials, while processing alters or refines existing materials into final forms.
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.
Purpose and Goal
Fabrication and processing serve different core objectives in the world of materials and products.
- Focuses on creating tangible products from raw or semi-finished materials.
- Often associated with the assembly of parts to form a larger system or product.
- Prioritizes the structural integrity and functionality of the final item.
- Aims at transforming or refining raw materials into a more usable or final form.
- Commonly used to enhance the quality, safety, or utility of a material.
- Ensures consistency and standardization in product batches.
Methods and Techniques
While both fabrication and processing involve manipulating materials, they utilize distinct approaches.
- Fabrication Techniques:
- Welding: Joining metals through the application of heat.
- Machining: Removing material to shape a workpiece.
- Bending: Adjusting metal’s direction without removal.
- Processing Techniques:
- Thermal: Heating or cooling materials to change properties.
- Chemical: Using chemicals to alter or refine a substance.
- Mechanical: Physical alteration, such as grinding or milling.
The choice of material often varies based on whether you’re fabricating or processing.
- Typically uses metals like steel, aluminum, and copper.
- Plastics, especially in industries like electronics or automotive.
- Involves a broader range of materials from foods to minerals.
- Chemicals, especially in chemical processing methods.
End Products and Outcomes
The end results from fabrication and processing are distinct in nature.
- Often results in tangible parts or products like metal frames, automotive parts, or machinery components.
- A focus on the physical and functional aspects of the product.
- Leads to refined or transformed materials, such as processed foods, refined minerals, or treated fabrics.
- Ensures safety, quality, and consistency of the end product.
