06 Jun . 26Metal Extrusion Basics
1. Historical Background The first hydraulic press was tested by J. Bramah in England in 1810, designed specifically for extruding lead. Later, in the 1890s, A. Dick applied the same principle to alloys with higher melting points in Germany. Dick used a pressure head (or disc) separated from the ...
