Viva Nylons has become synonymous with innovation, quality and technical excellence in relation to cast polyamide finished parts. The divisional integration between polymer production and components conversion has become a trademark for the company in providing machined components to a wide range of industries and clients.

Cast nylon finshed parts collection

Viva Nylons provides a full engineering solution for finished-machined mechanical plastic parts, with application engineers working directly with clients from initial concepts to the functioning finished component. Our in-house CNC milling machines and CNC lathes cater for production of complex components, particularly suited to environments where high friction and wear are evident. We cater for one-off prototypes through to medium and high-volume component batches.

  • Our CNC milling centres use 3-axis milling and 4-axis indexed milling to rapidly cut a choice of more than 20 mechanical-grade plastics into complex shapes and precision components
  • Our CNC turning centres use mechanical plastic rod and tube stock, which is rotated against live tooling to create final parts with axial and radial holes, flats, grooves and slots


6C materials can be milled on conventional machinery employing cutters with well backed off tooth forms. Sharp fly cutters, side and face cutters, slot drills and single-point tools are recommended. Cutter speed of 5m/sec. with feed rates of 4mm/sec. are achievable.

All work pieces must be securely supported during all milling operations.


6C materials should be turned using speeds of 3.0 – 4.5m/sec. (surface speed) with roughing cuts at feed rates (per rev.) of 0.010 –0.25mm. Without changing the feed rate, a perfect surface finish can be achieved with a cut of 0.025–0.041mm. High-speed steel tools are employed, providing a keen edge is maintained.

All work pieces must be securely supported during turning operations.

When boring 6C nylon rods ≥80mm ⍉, it is advisable to drill a 6mm → 10mm ⍉ pilot hole first. This process has the effect of releasing any residual stress and thereby prevents possible fracture of the component during machining.


General purpose drills are found to be suitable for 6C materials. They should be ground to an angle of 80o → 110o with a 10o → 15o lip clearance. Drill speeds and feed rates should be high, and the drill must be frequently withdrawn to prevent swarf build-up


A clean 6C appearance can be achieved without the use of coolants. Coolants are generally recommended for long production runs where extended tool life is preferable.
