The entire process of aluminum alloy profile extrusion processing

2024,12,04

Aluminum alloy extrusion processing is a process of shaping aluminum alloy billets into various shapes and sizes by applying pressure. Extrusion processing can produce aluminum alloy products with high strength, lightweight, and corrosion resistance, which are widely used in fields such as aviation, automotive, and electronic products. This article will provide a detailed introduction to the entire process of aluminum alloy profile extrusion processing.

Aluminum alloy profile extrusion processing flow

1. Preparation of billets: Firstly, strict inspection and screening of aluminum alloy billets are carried out to ensure that their size and quality meet the requirements. At the same time, the billet is cleaned and degreased to remove surface impurities and grease, ensuring the smooth progress of the extrusion process.

2. Heating before extrusion: Before extrusion, the aluminum alloy billet is heated to a certain temperature to give it good plasticity and flowability. Heating methods can include gas stoves, electric stoves, or induction heating. The reasonable heating temperature and time need to be determined based on the material of the billet and the extrusion requirements.

3. Extrusion process: On the extruder, the heated aluminum alloy billet is placed into a mold, and the shape and size of the mold determine the shape and size of the extruded aluminum alloy profile. During the extrusion process, the aluminum alloy billet is extruded from the mold by applying pressure to form the desired profile. The extrusion speed and pressure need to be adjusted reasonably according to product requirements and equipment performance.

4. Cooling and straightening: The extruded aluminum alloy profile has a high temperature and requires rapid cooling. Cooling methods can include water cooling, air cooling, or vibration cooling. At the same time, the cooled profiles are straightened to remove bending and deformation caused by compression.

5. Surface treatment and cutting: According to product requirements, perform surface treatment on aluminum alloy profiles, such as sandblasting, polishing, oxidation, etc. The processed profiles need to be cut to meet the length and specification requirements of different products. The cutting method can be sawing, milling, or plasma cutting.

6. Quality inspection and packaging: Conduct quality inspection on the cut aluminum alloy profiles, including size inspection, surface quality inspection, and mechanical performance inspection. Qualified profiles are packaged to prevent damage during transportation and storage. The packaging methods can include wooden frame packaging, cardboard box packaging, or plastic packaging.

Key control factors for extrusion processing of aluminum alloy profiles

1. Mold design: The design of the mold directly affects the shape, size, and mechanical properties of aluminum alloy profiles. Therefore, reasonable mold design is one of the key factors in extrusion processing.

2. Squeezing speed and pressure: The control of extrusion speed and pressure is crucial for the quality and performance of aluminum alloy profiles. Too fast or too slow extrusion speed, as well as too little or too much pressure, can lead to a decrease in the quality of the profile.

3. Cooling and straightening: The choice of cooling rate and straightening method will affect the microstructure and mechanical properties of aluminum alloy profiles. Rapid cooling and proper straightening methods can achieve better material properties.

4. Surface treatment and cutting: Choose the appropriate surface treatment method according to product requirements, while ensuring cutting accuracy and stability to meet the length, size, and shape requirements of the product.

5. Quality inspection and packaging: Strict quality inspection procedures can ensure that product quality meets requirements, and appropriate packaging methods can protect products from damage during transportation and storage.

Aluminum alloy profile extrusion processing is an important metal forming process with advantages such as high efficiency, low cost, and high quality. Understanding and mastering the entire process and key control factors of aluminum alloy profile extrusion processing can help improve production efficiency and product quality, and meet the needs of different fields.
