The extruder originated in the 18th century. The manual piston extruder manufactured by Joseph Bramah (England) in 1795 for seamless lead pipe is considered the first extruder in the world. From then on, during the first 50 years of the 19th century, extruders were basically only used in the production of lead pipes, macaroni and other food processing, brick and ceramic industries.

Bewlgy subsequently improved the extruder and used it in 1851 to coat the copper wire of the first submarine cable between Dover and Clais. In 1879, British M. Gray obtained the first patent for Archimedes spiral screw extruder. Over the next 25 years, extrusion methods became more and more important, and electric-operated extruders quickly replaced the traditional manual extruders. In 1935, Paul Troestar, a German machinery manufacturer, produced an extruder for thermoplastics. In 1939, they developed the plastic extruder to a stage of modern single screw extruder.
