FAQs about Surface Finishing
Surface finishing is a set of technique for altering the surface of a workpiece for the improvement of its functions or appearance. Example of surface finishing include painting, annealing, or anodizing.
The industry standard for surface finish is surface roughness measured by roughness average (Ra).
Different industries have their surface roughness requirements
Common types of surface finishes available at GS Proto include:
- Polishing
- Anodizing
- Plating
- Sandblasting
- Painting
Choosing any of the above depends on your project requirement, available finish, and the budget.
The surface finish is calculated using a profilometer which measures the workpiece surface roughness in micrometers or microns.
The surface finish of a product depends on the following:
- Manufacturing process
- Material type
- Tool quality
- Speed of production
Surface finish can help improve a part’s functionality or its aesthetics. For example, anodizing improves surface hardness and offer many color options while painting offers more of corrosion resistance and color options.
Use surface finishing process such as polishing or lapping to get a mirror like surface finish
Before you choose a surface finish technique, you must consider the part’s intended use, the type of material, whether you need functional, aesthetics, or both improvement.
Your budget and the industry requirement will also shape your choice. Contact us at GS Proto to guide you on making the right choice
Yes, some surface finishing methods can have environmental impacts. Techniques like plating and anodizing can produce toxic chemicals or waste which can impact the environment
Regardless, GS Proto complies with all environmental standards to minimize negative impacts.
Lead time for surface finishing services depends on the technique you use. Painting can be as fast as a two days while techniques like electroplating can take longer.
The driving force for the lead time of using a surface finishing option is the technique, part dimension, order size, and capability of the surface finishing service.
Lead time ranges from a few days to a couple of weeks
