Nylon machines differently from metal, and the problems usually show up after the part leaves the shop. Warping, dimensional shift, surfaces that look finished but won’t fit. VMT specializes in nylon CNC machining, and our process is built around preventing these failures so the parts you receive work the first time.
From industrial automation to medical devices, our nylon CNC machining services have produced parts across a wide range of industries. Every part is custom machined to your drawing and specifications.
Custom machined to tight bore tolerances, suitable for pivot shafts and rotary joints in automation equipment.
Machined for low friction sliding contact, commonly used in linear guides and conveyor systems.
CNC milled tooth profile for precise chain engagement, suitable for light to medium load power transmission applications.
Turned and milled to close concentricity tolerances, used in cable routing and tensioning systems.
Machined with smooth bearing surfaces, designed for low friction sliding contact in linear motion assemblies.
Precision machined blocks built for heavy load linear guide systems requiring consistent dimensional repeatability.
Precision machined wear pads for chain guidance systems, designed to absorb impact and reduce noise in conveyor and drive applications.
Milled housing components with tight dimensional tolerances, used in mechanical assemblies requiring electrical insulation and lightweight
Machined clamp blocks for shaft and tube retention, commonly used in automation equipment where metal clamps would cause surface damage.
Moisture absorption is a material property you cannot machine away, but you can design and prepare around it. Here is how we handle it:
Warping in nylon often stems from residual stress released during machining, combined with the material’s sensitivity to thermal changes. Here is how we control it:
Burrs and melted edges on nylon almost always come down to the same two causes: wrong tooling and too much heat. Here is how we address both:
| Capability | Standard Precision | High Precision |
|---|---|---|
| Dimensional Tolerance | ±0.05 mm | ±0.015 mm |
| Surface Finish (Ra) | 1.6 μm | 0.4 μm |
| Feature Position | ±0.05 mm | ±0.02 mm |
| Flatness / Parallelism | 0.05 mm | 0.01 mm |
| Max Part Size | 400 mm | 400 mm |
| Min Hole Diameter | 0.5 mm | 0.5 mm |
| Min Wall Thickness | 0.75 mm | 0.75 mm |
| CNC Axes | 3 / 4 / 5 Axis | 3 / 4 / 5 Axis |
| Machining Processes | Milling, Turning, Drilling, Tapping, Boring | Milling, Turning, Drilling, Tapping, Boring |
| Surface Finish Options | As Machined, Bead Blasting, Painting, Polishing | As Machined, Bead Blasting, Painting, Polishing |
Nylon parts go through different requirements at each stage of development. From early prototypes where design is still changing, to precision production runs where tolerances and surface finish are critical, our nylon machining services cover the full process so you don’t need to source from multiple suppliers.
The right choice for tight tolerances, complex geometries, and low to mid volume production. No tooling cost, no minimum order, and dimensions are cut directly from solid nylon stock, so what you get matches your drawing exactly.
For early stage prototypes where geometry needs to change frequently, SLS and MJF printing in nylon gives you functional parts fast without committing to machining setup. Best suited for design validation before moving to CNC production.
Injection molding suits high volume nylon parts with stable designs and moderate tolerance requirements. Once your CNC prototype is validated, we support the transition to mass production so your specifications carry through without requalifying a new supplier.
Different grades of nylon behave differently under load, heat, and moisture. Our nylon CNC machining services cover PA6, PA66, PA12, and glass-filled grades, so you can compare your options and choose the right material before production starts.
| Property | PA6 | PA66 | PA12 | Glass Filled (GF30) |
|---|---|---|---|---|
| Tensile Strength | 70 MPa | 82 MPa | 50 MPa | 130 MPa |
| Heat Resistance | 80°C | 110°C | 100°C | 200°C |
| Moisture Absorption | High | Medium | Low | Low |
| Flexibility | High | Medium | Low | Very Low |
| Advantages | Low cost, easy to machine, good toughness | Better strength and heat resistance than PA6, good dimensional stability | Lowest moisture absorption, excellent chemical resistance | Highest strength and rigidity, best dimensional stability, heat resistant |
| Disadvantages | High moisture absorption, dimensions shift in humid environments | More brittle than PA6, higher cost | Lower strength, higher cost | Brittle, abrasive to cutting tools, higher cost |
| Typical Applications | Gears, bushings, structural brackets, general mechanical parts | Bearings, wear pads, automotive components, high load parts | Medical devices, flexible connectors, chemical resistant parts | Aerospace parts, high load gears, electrical housings |
Choosing the right finish for nylon CNC machined parts depends on your functional requirements and operating environment. Our nylon CNC machining services support the following surface treatments:
Nylon behaves differently from metal at every stage of machining. Our team of 6 engineers reviews every drawing before production starts, catching design issues that affect dimensional stability, surface quality, and cost before they become real problems.
Every part is different. Submit your drawing for a free DFM review before production starts.
Our machining nylon process is backed by a rigorous inspection workflow and internationally recognised certifications, so every part that leaves our facility is documented and verified.
Nylon responds to heat, moisture, and stress differently from metal, so our inspection process is built around these specific variables. To help your nylon machined parts meet drawing requirements consistently, we follow a dedicated quality process:
Our nylon CNC machining operations are backed by internationally recognised certifications and full documentation on every order:
What is your standard lead time for nylon CNC machined parts?
Standard lead time for nylon machined parts is 10 to 15 business days depending on part complexity and order quantity. Expedited production is available on request.
Can you machine nylon parts with thin walls or complex geometries?
Yes. Our cnc machining nylon process uses geometry specific fixturing and optimised cutting parameters to handle minimum wall thickness of 0.75mm and complex multi-axis features.
Can you provide CMM inspection reports for nylon parts?
Yes. Every order of cnc nylon machined parts includes CMM dimensional verification. Full inspection reports and Certificates of Conformity are available on request.
What industries do you supply nylon CNC machined parts to?
Our nylon CNC machining services cover industrial automation, medical devices, optical instruments, aerospace, and electronics. Most parts we produce are custom machined to customer drawings.
Can you machine nylon parts to medical or food grade standards?
Yes. We support nylon precision CNC machining in biocompatible grades suitable for medical device components, with full material traceability and documentation provided on every order.
What nylon grade do you recommend for medical device components?
PA12 is generally recommended for medical applications due to its low moisture absorption and good chemical resistance. For structural components, Nylon 6/6 CNC machining in natural colour is also widely used. Final grade selection depends on your specific application requirements.
