Development trend of Plastic Extruders

The development trend of plastic extruders are as follows:
(1)Extruders are developing towards large-scale, high-speed and high-efficiency. It is not uncommon for foreign plastic extruders with screw diameters of 200-250mm to have special extruders with screw diameters greater than 400 mm. The production capacity of the extruder can be increased by increasing the diameter of the screw. When the diameter of the screw is doubled, the production capacity of the extruder can be increased several times.
(2) The auxiliary equipment of extruder has been improved and standardized to meet the requirements of different plastic products.

(3) Automation of extrusion, the process parameters of extruder are measured and controlled by microcomputer, and the temperature difference can be controlled within + 1. The extrusion equipment adopts microelectronics technology, which makes the plastic extrusion machine processing develop to the direction of accuracy, precision, energy saving and automation.
(4) In order to meet the requirements of new materials and new processes, new or special extruders are constantly emerging. Such as three-screw extruder, planetary multi-screw extruder, non-screw extruder, reactive extruder, two-color extruder, foam extruder, etc.
Nowadays,modern plastic granulation extruder has been widely used modern electronic and computer control technology, on-line detection of the entire extrusion process, and the use of microcomputer closed-loop control. In order to meet the diversified needs of production development, plastic molding technology has developed vigorously toward modern high-efficiency large-scale production and intelligent control.
