Industrial Processes - Finishes
Most products or artifacts have some kind of surface finish to either protect them when in use or to improve their appearance (Aesthetic Appeal). Some products are used outside and need to be protected against the elements.
Other products receive constant wear and tear (e.g. Friction) and would not have a very long life span if not protected.
A materials ability to resist any type of destructive treatment is called (a material's resistance to degradation).
Plastics generally do not need a finish to protect them as they are (self-finishing). The only finish they may require is polishing.
Woods and metals generally need a finish to protect them when in use. The finish may coat the surface forming a protective skin or the finish may be applied to the material and soak into the surface. This finish then becomes part of the material.
Programmes of Study
3l To ensure that the quality of their products is suitable for intended users.
4a To match materials and components with tools, equipment and processes;
4l To ensure through testing, modification and evaluation, that the quality of their products is suitable for intended users.
4c A range of industrial applications for a variety of familiar materials and processes;
5d About a variety of self-finishing and applied finishing processes, and to appreciate their importance
For aesthetics and functional reasons;
5e That to achieve the optimum use of materials and components, account needs to be taken of the complex interrelations between material, form and intended manufacturing processes.
