Against the background of global carbon neutrality goals, the whole industry of Plastic Extrusion Equipment is carrying out comprehensive energy-saving technological transformation, and low-power extrusion hosts and recycling matching auxiliary machines have become the core selection standard of plastic product manufacturers. The global plastic machinery market scale reached 7.6 billion US dollars in 2026, and the compound annual growth rate is expected to reach 5.1% by 2033, which is closely related to the tightening of carbon emission standards for manufacturing industries in various regions.
Single screw extruder and conical twin-screw extruder, two mainstream core hosts, have carried out key structural optimization. The new bimetallic wear-resistant screw barrel reduces melting energy consumption by 15%–20%, and allows mixing 30% waste plastic fragments without damaging the surface quality of finished pipes and profiles. The front-end feeding link is equipped with a fully sealed spiral feeder machine, which realizes automatic closed conveying of powder and particles, completely eliminating material overflow waste and dust pollution in the workshop.
The complete production line matches plastic crushers and mixing units to build a closed-loop recycling production system. Waste plastic scraps are crushed into uniform particles and sent to PVC hot-melt granulation production line for secondary melting and granulation, then re-transported to the extruder to produce new plastic products. All heating sections of the extrusion unit adopt electromagnetic heating modules, which save 40%–60% electricity compared with traditional resistance heating, complying with the EU mechanical energy efficiency regulations to be implemented in 2027.
European and Southeast Asian governments have launched tax subsidies for enterprises purchasing green extrusion lines, accelerating the elimination of outdated high-energy machinery. Equipment manufacturers focus on developing digital twin remote control systems, which can simulate extrusion parameters in advance to reduce raw material loss during trial production. Industry insiders said that low-carbon plastic manufacturing will become the core competitive track of extrusion equipment manufacturers in the next decade, and all supporting auxiliary machines will realize synchronous IoT linkage with the main extruder to further cut overall carbon emissions of plastic processing factories.
