Upset Forging

Engraving is a kind of manufacturing process ,which is commly apply to a hard, usually flat surface, by cutting grooves into it. And the aim to decorate the surface of the object and the material mostly can be as silver, gold, steel, and glass.But providing an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called engravings.

Traditional engraving, by burin or with the use of machines, continues to be practised by goldsmiths, glass engravers, gunsmiths and others, while modern industrial techniques such as photoengraving and laser engraving have many important applications. Engraved gems were an important art in the ancient world, revived at the Renaissance, although the term traditionally covers relief as well as intaglio carvings, and is essentially a branch of sculpture rather than engraving, as drills were the usual tools.

And compared to the traditional engraving,upset forging own its unique feature that upset forging is a metal shaping process in which a heated workpiece of uniform thickness is gripped between split female dies while a heading die (punch) is forced against the workpiece, deforming and enlarging the need of the workpiece.  A sequence of die cavities may be used to control the workpiece geometry gradually until it achieves its final shape.  This is a rapid "cold forming" process.
