A surprisingly wide range of surface finishes, each with distinct functional and aesthetic qualities, can be achieved by CNC machining nylon. Here's a rundown of the most common options:
1. As-Machined:
This is the unfinished product from the machining process; it has a slightly rough texture and obvious tool marks.
It is the most economical choice, appropriate for parts where function is more important than appearance.
As-machined parts can be given a light sanding or bead blasting to enhance their appearance.
2. Bead Blasted:
By saturating the part with tiny glass or plastic beads, a smooth, matte finish with strong wear resistance is produced.
It is a well-liked option for getting rid of tool marks and producing a consistent, slightly textured surface.
Bead blasting also produces a good grip and increases paint adhesion.
3. Media Tumbled:
Comparable to bead blasting, a softer, more rounded finish is achieved by tumbling media such as ceramic chips or walnut shells.
Perfect for softening edges and achieving a more natural appearance.
Suitable for areas that will be touched or in close proximity to skin.
4. Vibratory Finishing:
Polishes and deburrs the part using a vibrating tub filled with abrasive media, leaving it with a smooth, slightly glossy finish.
Compared to bead blasting, it provides a superior surface finish and is more efficient in accessing internal cavities.
Suitable for parts that need to be highly accurate in terms of dimensions and appearance.
5. Chemical Smoothing:
The outermost layer of nylon is dissolved and removed using chemical agents, leaving a glossy and smooth surface behind.
Excellent optical clarity is provided, making it perfect for transparent or translucent parts.
Not appropriate for every kind of nylon and might call for specific knowledge.
6. Painting and Coating:
Paint and other coatings can be easily applied to nylon to customize its color, texture, and other features like UV protection and waterproofing.
Provides practically infinite aesthetic options and can improve practical qualities.
Ideally, it adheres and lasts longer when the surface is properly prepared and the right coating is chosen.
Your intended aesthetics, functional needs, application, and budget are just a few variables that will influence the surface finish you choose for your CNC machining nylon parts.
