Aluminum extrusion is right on the die BeiAo die (or container) in the metal sheet increased work pressure, strong drive caused a plastic deformation, metal sheet from bay extrusion die of extrusion die hole, and then get the required cross section appearance, specification of aluminum anodic oxidation and has certain physical properties of parts or semi-product plasticity processing way.

Aluminum extrusion molding classification:

According to the direction of metal plastic flow, aluminum shield extrusion can be divided into the following types:

Forward extrusion: during production, the metal flow direction is the same as the punch fitness movement direction

Reverse extrusion: in production, the metal flow direction and punch fitness movement direction in reverse

Compound extrusion: production, part of the metal flow direction of the embryo material and punch fitness movement direction is the same, the other part of the metal flow direction and punch fitness movement direction in reverse

Tangential extrusion: during production, the flow direction of metal is 90 degrees from the fitness direction of punch

Technical characteristics of aluminum extrusion molding:

1, in the whole process of extrusion, the extrusion metal in the deformation area can be more obvious and symmetrical three-way reduction of internal stress than cold rolling calcination, which can make full use of the plasticity of the metal itself;

2, extrusion molding can not only produce simple cross section appearance of rod, tube, type, line goods, but also can produce more complex cross section appearance of aluminum and pipe;

3, extrusion molding operation flexibility, as long as the mold shell and other extrusion special tools, you can produce in a machine and equipment appearance specifications model and type of different products, the use of simple, convenient, time-saving, high efficiency;

4, extrusion products of high precision, product surface quality is good, but also improve the utilization efficiency of metal raw materials and pass rate;

5, the whole extrusion process has good harm to the physical properties of metal;

6, the production process is short, the production is convenient, one extrusion can be more than hot die forging or forming cold rolling and other ways of the total area of the overall parts.
