Extrusion molding is one of the important molding methods for plastic molding processing. Most thermoplastics can be processed by this method. Compared with other molding methods, extrusion molding has the following characteristics: the production process is continuous, the production efficiency is high, the application range is wide, and it can produce pipes, rods, plates, films , Monofilament, wire, cable, profiled materials and hollow products, etc .; less investment, quick results. Extrusion products can be widely used in people's daily life and industrial sectors such as agriculture, construction industry, petrochemical industry, machinery manufacturing, national defense and so on. However, most of the extruders currently used in our country have traditional structures, which are complex in structure, large in size, and high in energy consumption, and have become veritable "electric tigers." Sustainable development has become the focus of attention from all walks of life.

The AC servo motor drive system developed by Elesy is applied to the extruder to achieve precision extrusion and energy saving. Transmission system: (AC servo motor + AC servo controller) + screw. Its advantages are: simple structure, small size, convenient installation and maintenance. No gearbox, greatly reduced noise, no oil leakage, and improved working environment. It adopts PLC + servo controller control to realize stepless speed change, precise control of extrusion speed and extrusion volume, which meets the molding requirements of extruded plastic products with complex cross-sectional shapes and high process requirements. High transmission efficiency and greatly reduced energy consumption.
