Why Choose Parallel Twin Screws for High-Output Extrusion

In high-volume plastic extrusion—especially for profiles, panels, and sheets—manufacturers often face several key challenges: low output, poor melt consistency, and frequent machine downtime. This is where the parallel twin screw system becomes a powerful solution.

Parallel twin screws are designed for high-output, high-stability extrusion. With a constant screw diameter along the entire length, they offer a longer effective processing zone, allowing for better plasticizing, enhanced mixing, and more efficient material flow. For applications such as window profiles, wall panels, and technical profiles, this results in smoother surfaces and tighter dimensional tolerances.

One major issue customers often face is screw and barrel wear due to continuous operation and abrasive materials like PVC or wood-plastic composites (WPC). Standard screws may degrade quickly, leading to inconsistent production and expensive replacements. That’s why wear-resistant parallel twin screws—especially those with bimetallic liners or nitrided surfaces—are essential. They last longer, reduce maintenance costs, and help ensure steady, reliable output.

Another common pain point is poor material feeding or overheating during high-speed runs. Parallel twin screws, with optimized flight geometry and venting design, provide excellent temperature control and pressure stability—critical for heat-sensitive materials and additives.

At Zhoushan Juyuan Machinery Co., Ltd., we manufacture customized parallel twin screw barrels engineered for your specific extrusion application.
