Extrusion is the first step in aluminum profile production. The following is knowledge about aluminum profile extrusion.
 

1. Specifications of aluminum profile extrusion machines and diagonal lines of aluminum profile cross sections

 
The tonnage calculation of the extruder is based on the extrusion force, and the tonnage represents the extrusion force. Conventional extrusion presses have extrusion tonnages of 500t, 630t, 800t, 1000t, 1200t, 1800t, 2500t, etc. At Shangli, our extrusion presses have a tonnage of 5,000 tons. The size of the extrusion press tonnage is directly proportional to the size of the aluminum profiles that can be processed. In short, the larger the size of the extrusion machine, the larger the diagonal of the aluminum profile that can be produced, as shown in the figure below: Requirements for the size of the discharge port of a large extruder and the diagonal of the extruded profile.
 

2. Extrusion press size and aluminum profile

 
The extrusion press model and the specifications of the aluminum profile need to match each other. Usually, we will determine the extrusion ratio based on the load diagram of the aluminum profile, and then select an extrusion machine with appropriate specifications. The selection of the extruder is mainly based on the calculation of the extrusion ratio and is also related to the requirements of the aluminum plant. For example, if the extrusion ratio of an aluminum profile is only 5-15, then the design will require the aluminum factory to replace a large extrusion machine to meet the needs of product extrusion. However, for some aluminum profiles, the manufacturer only needs simple requirements, and the mold factory can continue with the design. Therefore, designers usually design the mold based on the information provided by the profile factory.
 

3. Selection of aluminum profiles and extrusion machines of corresponding tonnage

 
The extrusion press is the main equipment for producing aluminum profiles. Its shape, size and appearance quality are closely related to the selection of the extrusion press. At Shangli, we will choose the most suitable extrusion machine for you according to your customized aluminum profile 1 needs. We have rich industry experience and have a systematic understanding of extrusion press models, extrusion capabilities and grades. Now let’s explain how to choose the tonnage of the extruder.
 
Based on the type of alloy to be extruded, the annual production volume of a single machine and the maximum circumscribed circle diameter of the profile, we will initially select the type of extruder. The first issue to consider is the tonnage of the extruder. Generally, the extrusion ratio of the extruder must be calculated first. The extrusion ratio is also called the extrusion coefficient. It refers to the ratio of the cross-sectional area of the extrusion barrel to the total cross-sectional area of the aluminum profile. It is used to measure the aluminum profile in the production of aluminum profiles. The main parameters of alloy deformation. Expressed by the following formula:
 
If the extrusion processing method is used, the extrusion ratio is limited. The extrusion ratio λ of the primary extrusion aluminum profiles and aluminum rods during extrusion is greater than 8-12. The extrusion ratio of the blank used for secondary extrusion is There is no limit to the pressure ratio.
 
Before determining the tonnage of the extruder, it is necessary to understand the cross-sectional shape of the profile to determine the size of the mold and then determine the structural form of the mold. In this way, it can be determined whether the extrusion is a hollow profile or a solid profile. These two different There is a difference in the extrusion press tonnage required for structural profiles.
 
When selecting the tonnage of the extruder, we must fully consider the extrusion coefficient of the extruder, the cross-sectional shape of the profile and the size of the die, as well as our own production conditions and product requirements. According to the calculation formula, we can determine the amount of metal deformation. Only with the appropriate extruder tonnage can we extrude high-quality products that meet customer needs.
