Aluminum profile processing is a very important technology. There are many aspects that need to be considered when processing aluminum profiles because the effects of choosing different extrusion methods are different. In this blog post, we provide a brief overview of common aluminum extrusion types and processes.
Definition of the aluminum extrusion process
Aluminum extrusion involves applying pressure to an aluminum alloy material placed in a special mold. This process is called shaping. After forming, use a powerful punch to push the formed aluminum mold and extrude it from the die hole. This is a plastic processing method to obtain parts or semi-finished products with the required cross-sectional shape, size, and certain mechanical properties. Its processing principle can be understood as extruding toothpaste.
Aluminum extrusion process type
According to the type of metal in the extrusion barrel: stress and strain state, extrusion direction, lubrication state, extrusion temperature, extrusion speed, tool and die type or structure, blank shape or quantity, product shape or quantity, etc. Different, it can be divided into the forward extrusion method, reverse extrusion method, (including plane deformation extrusion, axial symmetric deformation extrusion, general three-dimensional deformation extrusion) transverse extrusion method, non-lubricated extrusion, lubricated extrusion, Glass lubrication extrusion method, static pressure extrusion method, continuous extrusion method, etc.
Forward heat deformation aluminum extrusion
During production, the metal flow direction is the same as the punch movement direction. This is a very common aluminum extrusion processing technology. It uses forward thermal deformation extrusion to extrude special molds (usually flat molds, cone molds, and split molds) to obtain customized aluminum materials with consistent cross-sectional shapes material.
The forward extrusion process is relatively simple and has a wide production range, high metal deformation ability, and great production flexibility. However, due to the relatively large friction between the extrusion barrel and the aluminum material, the yield will decrease to a certain extent. The extent of the damage. But these are minor issues that Ruitai‘s post-processing process can easily handle.
Process characteristics of extrusion molding
Fast, time-saving, and efficient: By simply changing extrusion tools such as molds, products of different shapes, specifications, and varieties can be produced on one piece of equipment.
Extrusion offers great flexibility: a single extrusion can produce monolithic structural parts with a larger area than hot forging or form rolling.
High precision: The extrusion products have high precision and the surface quality of the processed product parts is good.
Versatile production: Extrusion molding can not only produce rods, pipes, molds, and wire products with simple cross-sectional shapes but also profiles and pipes with complex cross-sectional shapes.
Strong plasticity: Extruded aluminum has a stronger and more uniform three-dimensional compressive stress state than rolling and forging, is easier to process into customized part shapes, and has a stronger forming force.
The aluminum extrusion process is critical to producing parts with customized cross-sectional profiles. Different manufacturing levels have a great impact on aluminum profile products.
