CNC Machining
Nylon 12 is a polyamide made from monomers with 12 carbon atoms, which gives it lower moisture absorption than many other nylons. We supply Nylon 12 CNC parts across the UK, from single prototypes to production runs. Stock is typically supplied in black / white.
It combines good impact resistance and toughness with stable performance under heat, suiting functional parts that see repeated use. As a result it is often specified for complex structural parts, parts under thermal load and automotive parts. Its quoted tensile strength of around 31 MPa gives a useful guide when sizing parts.
Parts are CNC milled or turned and available in black or white. Send us a STEP file and we will quote your Nylon 12 CNC parts promptly, with UK-wide delivery. Finish options (as machined) can be confirmed when you order. Every order is checked against your drawing before dispatch.

Values shown are typical supplier figures for Nylon 12 and may vary with stock condition. Please confirm critical properties before production.
Yes. Nylon 12 is tough and impact resistant and stays stable under heat and repeated use. It can have a slightly grainy surface.
Plastics are softer and expand more with heat than metals, so very tight tolerances and thin walls need extra care. Achievable tolerances depend on part size, geometry and features, so mark any critical tolerances on a 2D drawing with your upload and they will be reviewed and confirmed in your quote.
Nylon 12 is usually supplied as machined, deburred or bead blasted.
Typical uses include complex structural parts, parts under thermal load, automotive parts and medical correction devices.
Nylon 12 absorbs less moisture than nylon 6, so it is more dimensionally stable in humid conditions. Nylon 6 has higher strength and stiffness. POM-C is an alternative for precise low-friction parts.
The typical lead time shown for Nylon 12 is 10 business days from an approved order. Quantity, finishing and any heat treatment can affect this, and your quote confirms the date before you order.
