Cast nylon sheet, rod, tube and engineering plastics
We cast nylon in our own plant. Buy it as stock shapes in standard sizes, or order it cut to size or fully machined.

Cast Nylon Sheet
Cast nylon sheet has higher crystallinity and lower internal stress than extruded nylon. Large, thick parts machine without warping.
Standard sizes
| Thickness | 8 – 150 mm |
|---|---|
| Sheet size | 1000 × 2000 mm · 1200 × 2400 mm |
| Cut to size | Strips, blocks and blanks |
| Surface | As cast or face milled |

Colours
- Natural (cream)
- Yellow
- Blue
- Black
- Green (oil-filled)
Applications
- Wear plates
- Slides and guides
- Conveyor side rails
- Cutting boards
- Crane outrigger pads
- Hopper liners

Cast Nylon Rod
Solid cast nylon rod is the raw material for turned parts such as gears, pulleys, wheels, bushings and pins. Used in place of bronze or steel, it cuts weight and maintenance noticeably.
Standard sizes
| Diameter | Ø 20 – Ø 600 mm |
|---|---|
| Length | 500 / 1000 mm (by diameter), cut to any length |
| Surface | As cast or turned |
Intermediate diameters and special lengths are made to order.
Colours
- Natural (cream)
- Yellow
- Blue
- Black (MoS₂)
Applications
- Gears and sprockets
- Pulleys and sheaves
- Wheels and rollers
- Bushings and bearings
- Pins and shaft bearings

Cast Nylon Tube
Hollow cast nylon tube machines into large bushings, rings, sheaves and rollers with much less waste than solid rod. That lowers both material cost and machining time.
Standard sizes
| Outer diameter | Ø 60 – Ø 1000 mm |
|---|---|
| Inner diameter | Matched to the outer diameter, with the wall you need |
| Length | On request |
| Surface | As cast or turned inside and out |
Share your finished part size and we will choose the most economical tube size.
Applications
- Large bushings
- Rings and flanges
- Rope and crane sheaves
- Conveyor rollers
- Bearing sleeves

Cast nylon grades
- Standard PA6GGeneral purpose; high strength and wear resistance. Natural, yellow, blue and black.
- Oil-filled cast nylonOil added to the material lowers friction and extends life in fast, unlubricated bearings.
- MoS₂ filledBlack cast nylon with molybdenum disulphide for better sliding and wear resistance.
- Heat stabilisedFor parts that run at high temperature for long periods.
Key properties
- High wear resistance
- Shock absorbing
- Quiet running
- Corrosion free
- Self-lubricating
- Easy to machine
- Food-grade option
