Recently, plastic extrusions (single-screw extrusions and twin-screw extrusions) into the plastic machinery and equipment manufacturing industry's most famous plastic extrusions have what competitive advantages?
Fast high-yield extrusion with high efficiency and high production of competitive advantages allows investors to make relatively low investments to obtain a relatively large output and high revenue. Still, the screw extrusion fast high-yield also adds some problems, such as the material in the screw to reduce the time of stay will lead to uneven material mixing plasticization, the material is subjected to too much shear is likely to lead to rapid heating. Thermal decomposition of the material, extrusion stability Control difficulties will lead to extrudate geometry fluctuations, so the accuracy of the relevant auxiliary equipment and control system must be improved, the screw and barrel wear intensified to use high wear-resistant, and ultra-high wear-resistant materials, reducer and bearing in high-speed operation under the premise of how to improve its service life and other problems must be solved entirely.
High-efficiency multi-functional plastic extrusion of high efficiency is reflected in the key to high output. With low energy consumption and manufacturing costs, its primary use has been broadened to food, feed, electrodes, explosives, building materials, packaging, pulp, ceramics, and other fields. In addition, the "one-step extrusion process," which integrates the mixing, pelletizing, and extrusion processes, is also worthy of great attention.
Larger and more sophisticated extrusion and molding equipment can reduce production costs, which is more competitive in large twin-screw pelletizing units, film-blowing units, pipe extrusion units, etc.
