This article explains how precise temperature control improves efficiency and product quality in twin-screw extrusion. It covers key temperature zones, including the feed section, mixing zone, vent port, and die head, and analyzes how temperature interacts with feeding speed, screw speed, melt pressure, and filtration. The guide emphasizes coordinated process control to achieve stable extrusion, effective dispersion, and energy-efficient, environmentally compliant production.

This article introduces four essential screw-cleaning methods used in modified plastic production, especially for twin-screw extruders. It explains the working principles, operating procedures, advantages, and limitations of resin purging, mechanical disassembly cleaning, flame cleaning, and water-based hydrodynamic cleaning. By comparing their effectiveness, risks, and application scenarios, the article helps manufacturers choose the most suitable method for different materials and contamination levels. It also highlights the importance of proper operation, regular maintenance, and standardized cleaning processes to improve product quality, reduce defects, and extend extruder service life.

This article discusses how to increase the output of a twin-screw extruder by optimizing the screw configuration. It explains how improvements in feeding efficiency, melting performance, side feeding design, mixing quality, and pressure build-up can enhance extrusion productivity. By adjusting the screw elements, such as conveying and kneading blocks, manufacturers can achieve higher throughput, better material dispersion, and more stable processing without changing the extruder size.

Seaweed–polymer extrusion is an innovative and sustainable method of processing seaweed directly into polymer materials such as pellets, films, filaments, and 3D-molded parts. Unlike conventional fossil-based polymer production, this process minimizes CO₂ emissions while utilizing all natural seaweed components. The resulting seaweed-based polymers, known as Carraphane, offer biodegradable and eco-friendly packaging solutions with potential applications in films, small parts, and recyclable products. Continuous research aims to enhance water resistance and expand their role in the circular economy.
