About the material

Nylon 6/6 is the most commonly used of the Nylon family of plastics. It enjoys relatively high chemical and heat resistance, and is stiff enough to retain its shape, but tough enough not to permanently deform under load.

Two of the most notable use cases for Nylon 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.

Design Recommendations

Min Wall Thickness

0.5 mm

Min End Mill Size

0.8 mm (0.03 in)

Min Drill Size

0.5 mm (0.02 in)

Max Part Size (xyz, mill)

1200 x 500 x 152 mm [x,y,z] (mill)

Radii : Depth

Depth must not exceed 12x drill bit diameter.
For end mills, depth must not exceed 10x tool diameter.

Cost Saving Tip

To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.


Tolerance Stack Ups 501: Going Beyond Mechanical Fit and Into Predictive Design

Tolerance Stack-Ups are a vital component of any engineer’s workflow, to ensure successful mechanical design fit. But successful engineers in demanding industries such as medical, aerospace, and automotive, need to rely on data to do more than this. They need data to improve real design outcomes beyond “guess and check” — to improve design understanding […]

3-Axis to 12-Axis: CNC Milling Machine Capabilities Compared

Computer Numerical Control (or CNC) machining combines the efficiency of computer programming with the accuracy of lathe machines. The programmed software controls the movement of the tools and other machinery, thereby automating the manufacturing process and maintaining design consistency. Modern-day multi-axis CNC Milling Machines come with a wide range of features, which adds value and […]
