Aluminium profile extrusion technical knowledge

　　First, the principle of aluminium extrusion

　　Aluminium extrusion is a plastic processing method that applies external force to the metal billet placed in the container (extrusion cylinder) to make it flow out from the specific mold hole to obtain the required cross-section shape and size.

　　Second, the composition of aluminium extrusion machine

Aluminium extrusion machine consists of machine base, front column frame, tension column, extrusion cylinder, hydraulic system under electric control, and is equipped with mold base, ejector pin, scale plate, slide plate and so on.

　　Third, the classification of aluminium extrusion method

According to the type of metal in the aluminium extrusion cylinder, stress-strain state, aluminium extrusion direction, lubrication state, extrusion temperature, extrusion speed, the type or structure of the die, billet shape or number of products of the shape or number of different, can be divided into positive extrusion method, reverse extrusion method (including plane deformation extrusion, axial symmetry deformation extrusion, general three-dimensional deformation extrusion), lateral extrusion method, glass lubrication Extrusion method, hydrostatic extrusion method, continuous extrusion method and so on.

　　Four, forward thermal deformation extrusion

The vast majority of hot deformation aluminum production enterprises adopt the forward thermal deformation extrusion method through a specific mold (flat mold, cone mold, sectional mold) to obtain the aluminum material with the required section shape, which is also the conventional Aluminum Profile production method taken by Foshan Changyin Precision Manufacture Company so far!

       Direct extrusion process is simple, the equipment requirements are not high, the metal deformation capacity is high, the production range is wide, the aluminium properties can be controlled, the production flexibility is large, and the tooling is easy to maintain and repair.
