Φ50 Nylon Rod Extrusion Production Line

Product Overview

The Φ50 nylon rod extrusion production line is a complete turnkey solution for manufacturing solid PA6/PA66 round rods with a 4-strand die design, capable of producing two rod diameters (Φ40mm and Φ50mm) with one machine. From pellet feeding to finished rod stacking, every stage is automated in a single continuous flow, making it an efficient choice for suppliers of engineering plastic rods, gears, bushings and wear parts.

Designed for stable, long-running production, the line is driven by a 15kW main motor with frequency inverter control and a PLC-based control system, giving operators precise speed regulation and repeatable process conditions. With an output of 15–30 kg/h, it suits both small plants entering the nylon rod market and established manufacturers expanding capacity.

Standard Configuration

The complete line consists of six core units, each selected for reliability and easy maintenance:

Spiral feeding and drying system

1. — a 300G auto loader together with a 50KG drying hopper removes moisture from PA pellets before extrusion, preventing bubbles and voids in the finished rod.

Φ50 single screw extruder

2. — the heart of the line, featuring a nitrided screw and barrel made from high-grade alloy steel for excellent wear resistance and a long service life, with multi-zone independent temperature control for uniform plasticizing.

Solid rod die set (4-strand)

3. — precision die with sizing sleeve, forming up to four solid rods at once in Φ40mm or Φ50mm, with a die stand for quick alignment.

Caterpillar traction machine

4. — servo-driven upper and lower belts grip the rods steadily, ensuring constant pulling speed and consistent rod diameter.

Synchronous saw cutting unit

5. — frequency-controlled automatic cutting at preset lengths, with water spray cooling and a chip collection trough for clean, square rod ends.

Stacking rack and mold temperature controller

6. — a 1.5m galvanized stacking rack for orderly collection, plus a mold temperature control unit that keeps the die at a stable working temperature.

Why This LineOne machine, two diameters

● — the 4-strand die set produces Φ40mm and Φ50mm rods on demand, giving you product flexibility without extra investment.

Stable output

● — frequency inverter plus PLC control keeps screw speed, traction pull and cutting cycle synchronized, reducing downtime and material waste.

Long service life

● — nitrided alloy steel screw and barrel resist wear even with glass-filled or high-viscosity PA grades.

Easy operation

● — centralized control cabinet with independent zone switches makes setup, adjustment and maintenance straightforward for operators of any experience level.

Applications

The rods produced by this nylon rod extrusion production line are widely machined into gears, bushings, rollers, guide rails, insulation parts and wear plates for textile machinery, food processing equipment, conveyor systems, printing machines and automotive components. Nylon's self-lubricating, low-noise and impact-resistant properties make it a popular metal replacement in mechanical engineering.

Service & Customization

We provide complete support from plant layout and installation guidance to operator training and after-sales spare parts. Custom configurations — different rod diameters, colors, or higher output — are available on request.
