In recent years, high-speed, high efficiency, energy saving has been the main theme of continuous improvement of international plastics machinery. We will enable high-speed and high-yield investors a lower return on investment was high. However, the screw speed of about a series of very high-speed solution to the question: If the material in the screw to stay within a short time, mixing plastic materials easily lead to uneven; high shear may be caused by sharp temperature materials and thermal decomposition; Stability may be out of the question; Auxiliary and the need for high-performance control systems with sophisticated facilities; screw and barrel wear and tear, as well as slow down transmission box design and so on. As a result, for high-speed potential to provide solution, is the twin-screw supplier of technological innovation important one.
(Berstorff) Germany has introduced a new twin-screw extruder-ZEUTX series, the performance difference is to have a good screw diameter / productivity ratio. Screw the maximum design speed of up to 1200rpm, torque, out of production capacity in the 100 ~ 3500kg / h between. At the same time mixing the material, the reaction processes, such as exhaust. Screw and barrel modular design that can meet the requirements of a variety of special technology, processing technology with excellent flexibility, ZSEF also has the side-feeding, can achieve high transfer rate of solid particles, granulator May yield a different match and materials processing.
In order to adapt to high-speed & high-yield, the extruders have a number of improvement. Equipped with a heater tube, in a very short period of time to complete the extruder temperature, the maximum heating temperature of up to 450 ℃; flow cooling design truly reverse the flow of cooling and optimize the cooling system; configuration of the "bow-shaped folder Compact device "to replace the barrel of time than traditional bolt-faster connections; barrel uses a patented high-frequency hardening quenched technology to give excellent wear resistance and thus eliminate the need for high wear-resistant bush; In addition, the company is equipped with advanced process control system.
Multi-function
The twin-screw extruder is no longer limited to the molding and mixing of the higher polymer material, it has been extended to food, feed, explosives, building materials, packaging, pulp and ceramics and other fields. In addition, the mixing and granulation combined extrusion process of "one-step process directly out of the" very attractive.
WPC (WPC) for outdoor applications, such as the ceiling for the deck and fence have been for a long time, especially in the United States, Cincinnati Fiberex specializes in the development of the series, and we will continue to make the best of shape for the WPC. The fourth-generation Fiberex, with a long, wear-resistant processing unit, is able to fully meet the different requirements of customers, and achieve high yields. In last year's NPE show, the Cincinnati company demonstrated the entire Fiberex pilot production lines, production lines with a production capacity of 200 kg / h (440 lb / h) of Fiberex T58 extrusion machine for forming 75% The amount of wood flour-filled PP-allocation mix. Their manufacturing production lines have furniture industry profile, wall thickness 2.5mm and the speed out of shape 2m/min.
Large-scale and precision
Extrusion equipment for the realization of large-scale production can reduce the cost of grain for large-scale twin-screw unit, blown film crew, especially pipe group. In China, large-scale long-term dependence on imported equipment, large-scale twin-screw is being made of grain research unit. It can improve the precision of gold products, such as multi-layer co-extruded composite film. Melt gear pump out as an important means of precision should make greater efforts to carry out research and development. |
