Finishing Techniques
Finishing Techniques
Finishing techniques are processes used to finalise a surface to allow bonding, improve aesthetics, or increase durability.
Finishing techniques are essential in manufacturing, serving two primary purposes:
- Protection: Shielding materials from environmental factors like corrosion, wear, and UV radiation.
- Enhancement: Improving the aesthetic appeal and tactile qualities of a product.
- Finishing techniques are not just about aesthetics.
- They play a crucial role in ensuring a product's durability and functionality.
Types of Finishing Techniques
Finishing techniques can be broadly categorised into natural and human-made methods.
Natural Finishing Techniques
NoteNatural finishing techniques often involve minimal chemical processing and are typically used on organic materials like wood and leather.
Oils and Waxes
Oils (e.g., linseed, tung) and waxes (e.g., beeswax, carnauba) are applied to wood and leather to:
- Enhance the natural grain and color.
- Provide a protective barrier against moisture and dirt.
- Improve the tactile feel of the surface.
Polishing
Polishing
A finishing technique that makes a surface smooth and shiny by rubbing it, often with an abrasive material.
- Commonly used on metals, stone, and wood.
- Enhances aesthetics by creating a shiny surface.
- Reduces friction, improving functionality in mechanical parts.
When polishing, always use progressively finer abrasives to achieve the best results.
Human-Made Finishing Techniques
NoteThese techniques often involve chemical or electrical processes to enhance durability and appearance.
Anodizing
Anodizing
An electrochemical process that creates a thick oxidized coating on the surface of a metal component, usually aluminium or its alloys, to improve durability and appearance.
- Create a protective oxide layer that resists corrosion.
- Allow for coloring by absorbing dyes into the oxide layer.
- Enhance surface hardness and wear resistance.
Anodized aluminum is commonly used in smartphone casings for its durability and aesthetic appeal.
Electroplating
Electroplating
A process that uses an electric current to trigger a chemical reaction, forming a metal coating on the surface of a product.
