Extruder originated in eighteenth Century, since the development, technology is also constantly upgrading, K this year, Reifenhuser to "Rethinking" as the theme, exhibition extruder prototype and a 2020.
One of the research in the future is plasticized Energizer launch concept innovation, can minimize the energy input, screw barrel parts without cooling. Using Energizer, in the same yield and quality under the melt, melt temperature can be reduced by 20 degree.
In the extruder this concept of the future, Reifenhuser extrusion technology with special emphasis on energy, power, reliability, maintenance, operation and the role of design and functionality. The concepts of how far away we are? All these concepts together, and ultimately to achieve commercial production economics, Reifenhuser that takes six years.
Through cooperation with Siemens, extrusion technology and in particular to demonstrate the concept of motor drive can be free to choose out of form, without the need for additional engineering investment, customers can motor protection and cooling way free to select the desired. This technology is expected in 2015 will enter the market. Application of another prospect is cooling and heating using the Peltier element in the target segment of the slotted sleeve.
Plastic extruder is mainly reflected in the high output, low energy consumption, low manufacturing cost. In the aspect of function, screw extruder is not only used for extrusion of polymer materials and mixing process, its use has been extended to the field of food, feed, electrode, explosives, building materials, packaging, paper pulp, ceramics etc.. In addition, the mixing and granulation and extrusion process Become "one-step extrusion process" are also worthy of attention.
Extruder developed countries now has been commonly adopted in modern electronic and computer control technology, the extrusion process parameters such as melt pressure and temperature, the body temperature, the main screw and the feed screw speed, feed rate, the ratio of the motor parameters, a variety of raw materials, the current and voltage, online testing, and using microcomputer closed-loop control. Some companies have been using online remote monitoring, diagnosis and control, the network control extrusion production line. To ensure the stability of the process conditions, improving the precision of products are very favorable.
