Development History Of The Extruder
Jul 21, 2018

The extruder originated in the 18th century, and the manual piston extruder manufactured by Joseph Bramah (England) in 1795 for the manufacture of seamless plumbing 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 it was clearly stated is the patent that R. Brooman applied for the production of Gutebo adhesive wire by an extruder in 1845. H.Bewlgy of Gutepo subsequently improved the extruder and in 1851 used it 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 quickly 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 modern stage - the modern single-screw extruder stage.
