Nylon 6 is versatile and affordable, offering good toughness and machinability. Nylon 66 provides higher strength, stiffness, and heat resistance, making it suitable for demanding environments.

Choosing the right grade depends on your application requirements such as load, temperature, and wear conditions. For most general applications, Nylon 6 works well, while Nylon 66 is recommended for precision, high-performance parts.

Tolerances define how close a part’s dimensions are to its design. In nylon CNC machining, typical tolerances reach ±0.01mm. However, due to nylon’s thermal expansion and moisture absorption, design allowances must be considered.

Engineers should balance tolerance with function and cost—tight tolerances increase machining time and price. Understanding achievable tolerances helps ensure parts meet both performance and budget requirements.

Although nylon is naturally smooth, additional finishing can enhance performance and appearance. Polishing improves surface smoothness and reduces friction. Laser marking adds permanent part identification.

For assemblies, surface treatments may include inserts or coatings to increase wear resistance. Choosing the right finish depends on your application’s mechanical, cosmetic, and branding needs. At RALLY, we provide flexible finishing options tailored to your parts.

Nylon and POM (Delrin/Acetal) are both popular engineering plastics, but they differ in performance. Nylon is stronger, tougher, and more heat resistant, while POM offers lower friction, better dimensional stability, and easier machining.

Nylon suits structural parts like gears and bushings, whereas POM excels in precision components like bearings and connectors. The best choice depends on whether strength or dimensional accuracy is your priority.

CNC nylon parts are widely used in multiple industries. Automotive manufacturers rely on nylon gears and bushings for durability and lightweight design. Electronics use nylon washers and insulating parts.

Industrial machinery adopts nylon rollers and guides for smooth operation. Even consumer appliances employ nylon housings and fasteners. Its strength-to-weight ratio and wear resistance make nylon a versatile choice across engineering applications.
