Aluminum Extrusion Process Steps
1. Process raw materials as aluminum raw materials are called billets. Aluminum tickets are heated to 350 - 500 degrees Celsius. 2. After the billet reaches the desired temperature, the lubricant is transferred onto the film as a thin film. Heat will prevent the mold and the material from sticking together. 3. The billet is transferred to the carrier. 4. The billets are pushed in turn into the RAM enclosure. 5. Aluminum billets larger than the mold are in full contact with the carrier walls, crushed by the opposite mold. As aluminum is pushed through the mold, the liquid flows around the mold to cool the nitrogen process. In some cases nitrogen gas is used instead of liquid nitrogen. 6. The pressure finisher billet aluminum begins to squeeze out of the cavity of the mold. 7. The temperature is instantaneously measured and recorded during the extrusion process. The aim of knowing the temperature is to be able to maintain maximum pressure velocities. The target outlet temperature at the extruder also depends on the aluminum alloy. For example, for 6063, 6463, 6063A and 6101, the output temperature is at least 500 ° C 8. During profile drawing, the extrusion outlet is cooled by a series of fans along the length of the cooling table 9. On the billet block the oxidized part is discarded. 10. When the aluminum profile reaches the desired length, it is cut with the help of a profile saw. 11. The cut Aluminum Profile is transferred to the cooling compartment. 12. The aluminum profile is advanced, moved and cooled, then transferred to the next division, subjected to stretching and aligning operations (this part is important, there may be companies that do not do this in terms of cost and loss of work power). 13. The next step is the cutting saw. Aluminum profile is transferred to cutting saw and cut with certain length according to customer demand. 14. After the profiles are cut, they are placed in thermal baskets and transported into the furnace. Aluminum is hardened by aging (thermal treatment) in a controlled temperature environment. (This section is important, companies that do not do this in terms of cost and loss of work.) 15. Thermo-processed profiles shall be packaged and ready for delivery if no surface treatment (anodic coating, painting, wood transfer, etc.) or mechanical processing is to be done.
