Common extrusion methods can be divided into the following categories.
 
(A) Forward extrusion, metal flow direction and transverse direction of movement of convex consistent. Is divided into a solid piece extruded hollow forward extrusion is extruded two.
 
Forward extrusion method can create various shapes of solid and hollow parts such as screws, spindles, tubes and shells and so on.
 
(B) Anti-extrusion, metal dust flow direction and punch movement in the opposite direction, anti-extrusion method can produce a variety of cross-sectional shape of the cup-shaped pieces,
 
Such as the instrument casing, universal joint bearing covers.
 
(C) The combined extrusion, metal flow direction and the rough part of the punch movement in the same direction, while the other part of the metal dust and convex flow direction is mode of movement in the opposite direction,
 
Composite extrusion can produce double-cup type parts; you can create glass rods and levers parts.
 
(D) Diameter extrusion to a lesser extent by a metamorphosis is extrusion, cross-section only for mild rough cut. Mainly used in the manufacture of diameter less stepped shaft
 
as well as the deep cup-shaped piece of finishing processes.
 
Squeeze more than a few common characteristics: gold dust flow direction parallel with the axis of the punch, it can be referred to as axial extrusion. There are also radial extrusion and upsetting squeezing.
