 As Machined The natural finish achieved through the machining process enhances the surface properties of PA(Nylon), making it suitable for use in its machined state. | Functional and structural components |
 Sand Blasting This finish imparts a frosted or matte appearance to PA(Nylon), effectively reducing visible tool marks. | Aesthetic parts, visual housings |
 Teflon Coating Teflon coating can be applied to PA(Nylon) to enhance wear resistance and reduces friction, beneficial in high-wear or sliding applications. | Bushings, sliders, moving assemblies |
 Painting Nylon parts can be coated with paint for visual enhancement or protective finishes. Their slightly porous surface generally accepts paint better than many plastics,although using a primer is often recommended to ensure good adhesion. | Covers, non-load shellsCovers, non-load shells |
 Powder Coating (Less Common) PA(Nylon) can be powder coated using specialized techniques, providing a durable and protective surface finish in various colors, although this is less common. | Customized industrial enclosures |
Due to moisture absorption and thermal limits, PA(Nylon) often requires surface preparation (e.g., drying, priming) before painting or coating.
We provide precision CNC machining services for Nylon (Polyamide), a versatile and durable engineering plastic known for its strength, wear resistance, and machinability. Below are recommended guidelines to achieve high-quality results. Actual settings may vary based on machine setup, tooling, and part design.
| Parameter | Recommended Range | Notes |
| Tooling | Carbide or HSS tools with sharp edges and positive rake (~10–15°); diamond‑coated inserts for filled Nylon | Sharp tools reduce friction and heat; polished flutes help evacuate chips and improve surface finish |
| Cutting Speed (SFM) | Unfilled Nylon: 500–1000 SFM. Glass‑filled Nylon: 300–600 SFM | Higher speeds help reduce heat; reduce speed for abrasive grades |
| Feed per Tooth / Rev | Roughing: 0.10–0.30 mm/rev (0.004–0.012"); Finishing: 0.08–0.20 mm/rev (0.003–0.008") | Faster feeds minimize heat accumulation; reduce feed for filled materials |
| Depth of Cut (DOC) | Rough: 2–5 mm; Finish: 0.5–1 mm | Multiple light passes improve surface quality and dimensional accuracy |
| Cooling / Chip Control | Dry machining with compressed air or mist coolant; frequent chip evacuation | Avoid moisture-induced swelling; Prevent chip recutting and surface blemishes |
| Machining Strategy | Climb milling, high-helix tools, adaptive clearing | Minimizes heat and tool pressure, improves finish |
| Pre‑Drying Material | Dry Nylon at ~65 °C for 12–16 hours to below ~0.2% moisture content | Prevents dimensional changes during machining |
| Fixturing | Use soft jaws or vacuum holding; avoid over‑clamping | Prevents deformation, especially in thin geometriesPrevents deformation, especially in thin geometries |
| Tolerances / Surface Finish | Standard: ±0.05 mm; Precision: ±0.02 mm or better with controlled conditions | Consistent results on tough, wear-resistant components |
Our CNC-machined Nylon (PA6 / PA66) components deliver precision, durability, and versatility across industries—including automotive, industrial machinery, electronics, and consumer products. With a great strength-to-weight ratio and outstanding wear resistance, nylon is ideal for structurally demanding and motion-intensive parts.
