ZXSJ-30 · Single Screw Extruder

Equipment introduction:

The extruder originated in the 18th century, and the manual piston extruder manufactured by Joseph Bramah (England) in 1795 for the production of seamless lead pipes was considered to be the world's first extruder. Since then, during the first half of the 19th century, extruders have been basically only suitable for the production of lead pipes, macaroni and other food processing, brick making and ceramic industries. In the development process as a manufacturing method, the first time clearly stated is the patent that R. Brooman applied for the production of Gutebo adhesive wire by an extruder in 1845. G. Wave's H. Bewlgy then improved the extruder and used it in 1851 to coat the copper wire of the first submarine cable between Dover and Calais. In 1879, the British M. Gray obtained the first patent using the Archimedes spiral screw extruder. In the next 25 years, the extrusion process became increasingly important, and the electric hand operated extruders gradually replaced the previous manual extruders. In 1935, German machine manufacturer Paul Troestar produced extruders for thermoplastics. In 1939 they developed the plastic extruder to a new stage – the modern single-screw extruder stage.

The characteristics of the extruder are mainly reflected in the following points:

1. High speed, high output, stable output, and no attenuation with time or speed.

2, low temperature melt plasticization, material plasticization is uniform.

3. The plasticizing process is controlled, and only particles smaller than the isolation gap can enter the melt channel.

4. The material melt is extruded at a lower temperature.

5, using digital control, PLC control and PCC industrial computer control three control systems, to meet the needs of different customers.
