HDPE rod is a solid plastic bar made from high-density polyethylene. It’s commonly used for machining wear parts, rollers, guides, spacers, bushes, and marine components. HDPE rod is valued for its impact resistance, low friction, and moisture resistance in industrial, food handling, and outdoor applications.

HDPE rod offers high impact strength, good chemical resistance, low moisture absorption, and excellent machinability. It has a lower stiffness than nylon or acetal but performs well where toughness and durability are more important than tight tolerances or high load-bearing strength.

HDPE rod is available in 20mm to 400mm of diameters, typically from small precision sizes up to large industrial rods. Lengths are usually supplied in standard stock sizes and can be cut to length. Availability depends on diameter, colour, and grade.

Yes. HDPE rod machines easily using standard woodworking or plastic machining tools. It can be turned, milled, drilled, and tapped. Due to its flexibility, sharp tools and correct feeds are important to maintain accuracy, especially on tighter tolerances.

HDPE rod is tougher and more impact-resistant but less stiff than nylon or acetal. It has higher thermal expansion and lower load capacity. HDPE is often chosen for wet environments or where chemical resistance and toughness matter more than precision.

Yes. HDPE rod can be welded using plastic welding techniques such as butt welding or extrusion welding. Mechanical fastening is also common. Adhesive bonding is generally unreliable due to HDPE’s low surface energy.
