Plastic extruders expected to realise plasticising concepts

Extruder began in the 18th century, since the development trend so far, technology is also continuing to update, 2021 K exhibition, Reifenhuser with "Rethinking" as the theme style, exhibition of a 2020 extruder prototype.

One of the scientific studies for the future is the release of the independent innovation of the melting concept Energizer, which can be reduced to the minimum kinetic energy input, the vast majority of the barrel without refrigeration. With the Energizer, melt temperatures can be reduced by 20 degrees for the same amount of production and melt mass.

In this futuristic extruder, Reifenhuser Extrusion Technology emphasizes the role of power energy, output power, stability, maintenance, practical operation, design and versatility. How far apart are those concepts? To put all these concepts together and finally complete the commercial production of economic development, Reifenhuser thinks it must take six years.

In collaboration with Siemens PLC, the extrusion technology company, in particular, has demonstrated the concept of extrusion drive, which can choose the motor mode at will, without additional project investment, the customer can choose the waterproof level and cooling method of the motor. This technical forecast will enter the sales market in 2015. Another futuristic application is the cooling and overall target heating of Peltier components in the slotted casing segment.

The key to the high efficiency of plastic extruders is reflected in the high return, energy saving and low manufacturing costs. At the functional level, the extruder screw extruder has not only been used for the extrusion forming of fiber materials and the production and processing of mixed rubber, its main use has been expanded to food, concentrate feed, electric grade, gunpowder, decorative building materials, packaging, paper paddle, porcelain and other industries. In addition, the "one-step extrusion process" that combines the mixing granulation and extrusion forming process is also worthy of great attention.

Extruders in today's capitalist countries have widely used contemporary electronic devices and electronic computer control systems, and the main parameters of the entire extrusion process such as melt working pressure and temperature, the overall body temperature of each section, the speed ratio of the main extruder screw and the feeding extruder screw, the feeding amount, the main extrusion process. The main parameters such as the preparation of various raw materials and the current intensity of the motor are monitored online, and the micro-computer closed-loop control system is selected. Some enterprises have selected online remote control detection, diagnosis and manipulation, to carry out networking control of extrusion forming production lines. This is extremely beneficial to ensure the stability of the processing standard and improve the precision of the product.
