Description
These acetal plastic rods are manufactured from high-quality acetal copolymer, providing excellent stiffness, dimensional stability and wear resistance in a versatile engineering plastic format. Supplied in 3000mm lengths and a comprehensive range of diameters from 3mm up to 36mm, they are ideal for machining into precision components, spacers, bearings and structural parts.
Available in both white and black grades, with smaller diameters such as 3mm, 4mm, 5mm, 6mm and 8mm supplied in convenient multi-length packs, these rods are widely used across industrial, mechanical, automotive and engineering workshops. Their low friction, good fatigue resistance and reliable performance make them a popular alternative to metal in many light to medium duty applications.

Key Features and Benefits
- Excellent machinability allows precise turning, milling and drilling on standard metalworking equipment, helping reduce production time.
- Low moisture absorption and good dimensional stability help maintain tight tolerances in service, even in humid environments.
- Low coefficient of friction and good wear resistance make these rods ideal for sliding or rotating parts where reduced lubrication is desirable.
- High stiffness-to-weight ratio offers a strong yet lightweight alternative to metal, easing handling and reducing overall assembly weight.
- Good fatigue and impact resistance provide long service life in dynamic, cyclic loading applications.
- Chemical resistance to many oils, greases and solvents ensures reliable performance in demanding industrial settings.

Applications and Ideal Uses
These acetal copolymer rods are suitable for a wide range of engineering and industrial applications where stable, low-friction plastic components are required.
- Machined precision components, spacers, bushes and wear strips in general engineering.
- Low-friction guide rails, sliders and rollers in material handling equipment.
- Mechanical parts, cams and gears in automation and machinery build.
- Jigs, fixtures and prototype parts in workshops and fabrication facilities.
- Replacement parts for light-duty bearings and seals where corrosion resistance is needed.
Frequently Asked Questions
Can these acetal rods be machined using standard metalworking tools?
Yes. Acetal copolymer rods can be easily machined using conventional metalworking tools such as lathes, milling machines and drills. Sharp tooling and appropriate cutting speeds are recommended to achieve a smooth finish and maintain dimensional accuracy.
Are the rods suitable for outdoor or wet environments?
Acetal has low moisture absorption and good dimensional stability, making it suitable for damp or humid environments. However, long-term outdoor exposure to UV may cause surface degradation, so for fully exposed external applications additional protection or alternative UV-stabilised materials may be preferable.
How do I choose the correct diameter and pack size for my project?
Select a diameter that comfortably covers the largest finished dimension of your machined part, allowing for machining allowances. Smaller diameters such as 3mm, 4mm, 5mm, 6mm and 8mm are supplied in multi-length packs, which are ideal for batch production of small components. Larger diameters are better suited to individual or larger components where fewer lengths are required.
