Why Choose Nylon for Engineering Parts?
Polyamide (Nylon) is a premier wear-resistant plastic, offering a superior strength-to-weight ratio and exceptional mechanical toughness for demanding industrial environments.
From Nylon gear machining to structural components, this material excels in high-load applications requiring fatigue resistance and excellent energy absorption.
Its natural self-lubricating properties significantly reduce friction, making it the ideal choice for custom Nylon bushings and wear-intensive moving parts.
Compare Material GradesHigh Impact Strength
Nylon absorbs significant kinetic energy without fracturing, making it perfect for high-impact housings and protective guards.
Self-Lubrication
Low friction coefficients enable the production of Nylon gears and slides that operate quietly with minimal maintenance requirements.
Chemical Resistance
Exceptional resistance to oils, greases, and fuels makes Nylon the engineering standard for automotive Nylon parts and fluid manifolds.
Nylon Material Grades Matrix: PA6 vs. PA66
Nylon 6 (PA6): Toughness & Value
PA6 (often processed as Cast Nylon) is the go-to choice for large-scale industrial components requiring high impact damping. It offers a balanced combination of mechanical strength and chemical resistance, providing a cost-effective solution for heavy-duty wear parts. For detailed insights on different materials, see our materials overview.
- Superior impact resistance and vibration damping
- Lower internal stress in Cast Nylon (MC) forms
- Ideal for large-diameter rollers, pulleys, and wear plates
Nylon 6/6 (PA66): High-Strength Engineering
PA66 (Extruded Nylon) delivers higher mechanical stiffness and thermal stability compared to PA6. With a higher melting point and lower moisture absorption rate, it excels in high-stress precision applications where dimensional stability under heat is critical.
- Enhanced fatigue performance for high-speed gears
- Higher melting point for engine-room environments
- Superior base material for Glass-Filled (GF30) reinforcement

Solving Critical Challenges in Nylon Machining
Nylon is known for dimensional instability. We expertly manage PA6 and PA66 variables through moisture control and annealing, ensuring parts meet strict tolerances. Explore our advanced solutions for nylon machining.
Moisture Expansion & Stability
Nylon absorbs up to 3% moisture, causing swelling. We calculate a precise Moisture Allowance and use non-aqueous coolants to ensure dimensional stability.
Burr-Free Nylon Engineering
Nylon's toughness often creates burrs. We use sharp carbide tooling and down-milling for burr-free Nylon components with clean edges, eliminating rework.
Warp-Free Plastic Through Annealing
Raw material stresses can cause warping. We use Symmetric Machining and multi-stage stress relief annealing to ensure warp-free plastic for all geometries.

Nylon Machining & Annealing FAQs
How do you manage Nylon's moisture absorption during machining?
Nylon is highly hygroscopic. We store all raw PA6 and PA66 in humidity-controlled environments and apply "Moisture Allowance" design strategies to ensure parts remain within specified tolerances after environmental exposure. For more details about our processes, please visit our about page.
Why is stress relief annealing critical for precision Nylon parts?
Annealing eliminates internal stresses caused by the extrusion process or heavy material removal. This thermal treatment prevents warping and ensures long-term dimensional stability for complex components like manifolds and housings.
Can you achieve tight tolerances on Glass-Filled (GF30) Nylon?
Yes. While glass fibers are abrasive, we utilize specialized carbide tooling and optimized feed rates to maintain tolerances of ±0.02mm, even on high-stiffness structural parts used in automotive and aerospace applications.
What is the advantage of CNC machining Nylon vs. Injection Molding?
CNC machining is ideal for low-to-mid volume production and prototyping. It allows for thicker wall sections, avoids expensive mold costs, and enables the use of high-performance grades like Cast Nylon (PA6) for large-scale industrial gears. If you have questions, feel free to contact us.
