How to Select Aluminum Extruder Correctly
In response to the increasingly complex cross-sectional shape and size of aluminum alloy profiles, aluminum profile extrusion machines, as the primary machinery and equipment for the production and manufacturing of metal aluminum, immediately endanger the appearance quality and precision specifications of aluminum alloy profiles. A good aluminum profile extrusion machine can bring very good economic benefits to the company. With the development trend of extrusion machines towards import substitution and intelligence, the demand for equipment is also increasing, How to choose a suitable extruder has become a common issue for aluminum alloy profile manufacturers. Below are some applicable selection criteria for reference only.
How to Select Aluminum Extruder Correctly
1. Select the extruder according to the model, which can be selected according to different structures. The methods and functions of transmission systems are mainly used in different types, including steam pressure, pressure, column type, and vertical pressure. When selecting the type of extruder, the variety and main use of aluminum alloy profiles can be used as a reference, such as 6063-T5 aluminum alloy profiles, which can be selected as a single acting horizontal extruder; For extruding soft aluminum alloy pipe fittings, a double acting horizontal extruder can be selected. Companies should select suitable extruders based on their own manufacturing and socio-economic standards. In specific industrial production, single acting horizontal oil presses are more commonly used.
2. After defining the types of extruders based on their extrusion working capacity, it is necessary to select the extrusion working capacity of the extruders. Extruders can be divided into super heavy, medium, medium, and small extruders according to their working capacity dimensions. The size of the extrusion working capacity should be calculated based on one's own manufacturing standards, technical strength, machine equipment standards, and market sales standards. The main parameters such as the annual production time, labor per hour, and so on should be calculated to estimate the annual production capacity of the extruder. Due to the size of the production capacity and cross-sectional dimensions, it is determined which type of extruder to choose, Different alloy components require different extrusion capacities. Generally, aluminum alloy profiles require extrusion pressures of 250-400MPa, hollow aluminum alloy profiles require extrusion pressures of 450-1000MPa, and pure aluminum profiles require relatively low extrusion pressures of 150-250MPa. There are also significant differences in pressing methods, with the forward direction pressing requiring 1/3 more pressing pressure than the reverse direction pressing.
3. Selection based on the level of extruder
After the type and working capacity of the previous binary extruder have been clarified, it is necessary to clarify the level of the extruder. It should be clarified based on the brand positioning and capital budget of aluminum alloy profile manufacturers. If the aluminum alloy profile products manufactured by the company are medium in quality, domestic extruders can be selected; If it is precisely positioned as a high-end product, it is necessary to select an extruder imported from abroad. Regardless of which level of extruder is used, it is necessary to calculate based on your own realistic standards. If you only produce medium aluminum alloy profile products and do not need to select an extruder imported from Germany, on the one hand, the amount of investment in the project is relatively large, and on the other hand, it is also very difficult to protect the future. After all, the costs in various fields will increase, and will continue to affect the progress of production and processing. It is necessary to act within your capabilities, Consider multiple aspects.
