Aluminum extruded is imposed the outside force to the metal germ material which put in the container(extruded tube),make it to flow out from the special mold hole,that is one way for the plastic process to be the requisite fracture surface shape and specification.
The composing of the aluminum extruded machine:
The aluminum extruded machine is composed of engine base,frontal column frame,tension column,extrusion cylinder,a hydraulic system by electrical control,the other is equipped with mold base,thimble,scale plate,plate etc.
Classification of extrusion methods for aluminum profiles
According to the direction of extrusion: forward extrusion, backward extrusion, lateral extrusion
According to the deformation characteristics: plane deformation extrusion, axisymmetric deformation extrusion, general three-dimensional deformation extrusion
According to the state of lubrication: no lubrication, extrusion, lubrication, extrusion, ideal lubrication extrusion
According to the extrusion temperature: cold extrusion, hot extrusion, warm extrusion
According to the extrusion speed: low speed extrusion, high speed extrusion, impact extrusion (ultra high extrusion)
According to the type of mold or mold structure: flat die extrusion, mold extrusion, split die extrusion, with perforation, needle extrusion
According to the type of equipment: vertical extrusion horizontal extrusion, continuous extrusion
