MJF Finishing Options for Nylon Parts
Choose finishing based on appearance, sealing, wear, and assembly requirements.
Standard Bead Blasting
Removes loose powder and evens the surface to a uniform matte finish. Recommended for functional parts where appearance consistency and clean handling are required.
Vapor Smoothing
Reduces surface roughness and improves cleanability and moisture resistance. Recommended for parts that require a smoother touch, better sealing surfaces, or improved cosmetic appearance.
Tumbling & Painting
Tumbling smooths contact points and softens the surface feel. Painting adds color and improves UV stability for visible housings and end-use assemblies.
Custom Finishes
Custom options available on request: dyeing, priming, threaded inserts, sealing, and secondary machining. Share your color target, cosmetic requirements, and any CTQ features during quoting.
