Aluminum extrusion molding (or aluminum extrusion molding) is to apply strong pressure to the aluminum billet placed in the die cavity (or extrusion cylinder), forcing the aluminum billet to produce directional plastic deformation, and extrude from the die hole of the extrusion die. To obtain a plastic processing method for parts or semi-finished products with the required cross-sectional shape, size and certain mechanical properties.
The principle of aluminum extrusion is similar to squeezing toothpaste.
The aluminum ingot is divided into several metal streams under pressure, enters the welding chamber through the shunt hole, gathers in the welding chamber, and is welded again under the environment of high temperature, high pressure and high vacuum, and finally passes through the core and mold. The gap between the holes flows out to form a pipe or hollow profile that meets the size and performance requirements. If bending is required, a bending tool is added to the rear equipment.
