Extrusion process of aluminum profile?

Extrusion forming of aluminum profile is an important metal plastic processing method. By applying strong pressure, the aluminum blank is forced to produce directional plastic deformation and extruded from the die hole of the extrusion die, so as to obtain the plastic processing method of parts or semi-finished products with required cross-sectional shape and size and certain mechanical properties. Understanding the extrusion process of aluminum profiles is of great significance for improving production efficiency, reducing costs and ensuring product quality.

raw material

The raw materials used in extrusion molding of aluminum profiles are aluminum alloy bars or blanks, which require high purity, uniformity and stability. Before extrusion, it is necessary to heat the aluminum alloy material to a suitable processing temperature, and at the same time pay attention to the surface treatment of the material to remove impurities such as oil stain and scale.

Extrusion preparation

Before extrusion, a series of preparatory work is needed. First of all, it is necessary to check whether the extruder is in normal working condition to ensure the good cooperation of all components. Secondly, it is necessary to adjust the distance between the extrusion die and the extrusion cylinder and preheat the extrusion die to avoid failure or die damage during extrusion.

Extrusion process

The core link of aluminum profile extrusion is the extrusion process, which includes the steps of profile heating, extrusion die and extrusion molding.

Profile heating: aluminum alloy materials are heated to a suitable processing temperature, generally by resistance furnace heating or gas furnace heating.

Extrusion die: according to the shape and size of aluminum profile to be produced, design and manufacture the corresponding extrusion die.

Extrusion molding: the heated aluminum alloy material is put into an extrusion cylinder, and the aluminum alloy material is plastically deformed by injecting high-pressure liquid into the extrusion cylinder or pressurizing by using a mechanical pressure device, and then extruded from the die hole of the extrusion die, thus completing the extrusion molding process of the aluminum profile.

post processing

After aluminum profile is extruded, post-treatment is needed to improve the quality and performance of the product. It mainly includes the steps of straightening, cutting, grinding and inspection.

Straightening: Straighten the extruded aluminum profile with a straightener to eliminate the bending and distortion caused by extrusion.

Cutting: cutting aluminum profiles according to requirements to obtain aluminum profile products with required length and specifications.

Polishing: Polishing the surface of aluminum profile to remove burrs and acute angles on the surface and improve the surface quality of products.

Inspection: Quality inspection of aluminum profile products, including size, shape and surface quality, to ensure that the products meet the requirements.

Extrusion forming technology of aluminum profile is an important metal plastic processing method, which is widely used in various fields. With the continuous development and progress of science and technology, the extrusion molding technology of aluminum profile will be continuously optimized and innovated to provide more high-quality and high-performance aluminum profile products for the industrial field.
