Background

Extruder was originated in the 18 th century and the hand-operated piston extruder manufactured by Joseph Bramah in 1795 for making seamless lead tubes was considered the first extruder in the world. Since then, during the first 50 years of the 19 th century, extruders were essentially only suitable for use in the lead tube production, macaroni and other food processing, brick making and ceramic industries. In the development as a manufacturing process, patent No. 1 explicitly described r.brooman in 1845 for the production of a cable of curebox with an extruder. The extruder was subsequently modified by the firm bow h.bewlgy and used in 1851 to clad the copper wire of the 1 st submarine cable between the Dover and Calais companies. In 1879, the first patent to use an archimedes screw extruder was obtained by the english man m.gray. In the next 25 years, extrusion processes have become increasingly important and the past manual extruders have been rapidly replaced by electrically operated extruders. In 1935 the German machine manufacturer Paul Troestar produced extruders for thermoplastics. In 1939 they developed the plastic extruder to a current stage, the modern single screw extruder stage.
