Nylon CNC Machining
Polyamide, or PA for short, is an important engineering plastic. PA has many excellent characteristics, such as high strength, wear resistance, chemical resistance, good heat resistance, and cold resistance.
Nylon is a trademark name by DuPont in the 1930s.
“Nylon” and “PA” both refer to the same material.
PA6 and PA66 are two common polyamide grades.
Nylon PA6 is one of the most common polyamides with good strength, toughness, and wear resistance. Nylon CNC machining parts are often used to manufacture gears, bearings, automotive parts, fibers, and various plastic products.
PA66 is another standard polyamide. Compared to PA6, it offers higher heat stability and rigidity. It finds wide applications in automotive, electrical, electronic, and industrial parts.

Cost-saving Design Tips
Nylon is a relatively inexpensive engineering plastic, however, to further save on machining costs, try the following:
1.Keep parts simple
To minimize machining set-ups and reduce the cost of the machine required (in other words, using a 3-axis machine versus a 4-axis or 5-axis machine), keep the geometry as simple as possible. A part with complex geometry may be a better candidate for 3D printing in Nylon 12 via SLS (selective laser sintering) or HP Multi Jet Fusion.
2.Keep parts consistent
Keep internal corner radii and tapped holes to consistent measurements to reduce the number of tool changes required by a manufacturer
FAQs
Nylon does not have metal in it. It is a strong, stiff engineering synthetic thermoplastic linear polyamide. Nylon is often used as a substitute for low-strength metals.
Two of the most notable use cases for Nylon CNC machining are in medical devices and electronics insulation, notably screws and spacers for panel mounted circuit boards.
Glass-filled Nylon boasts many great properties such as high rigidity, strength, hardness, toughness and dimensional stability. This material may be used in assemblies requiring mechanical damping or electrical insulation. Common applications include electrical housings, washers, medical devices and aerospace parts.
