1. Is the processing method of an aluminum profile extrusion press a plastic processing method? In addition, does this type of extrusion press have accessories?

Aluminum profile extrusion processing, from a professional perspective, applies external force to the metal billet inside the extrusion cylinder, causing it to flow out from a specific die hole to obtain a product with the required cross-sectional shape and size. Therefore, from its definition, its processing method is a plastic processing method. This type of extrusion press certainly has accessories; generally speaking, there are things like plungers, scale plates, and slides.

2. In the aluminum profile extrusion press, using the volume method and the practical weight method to calculate the aluminum rod parameters, are the calculation formulas the same?

In the aluminum profile extrusion press, the calculation of the aluminum rod parameters uses two methods: the volume method and the practical weight method, and their corresponding calculation formulas are different. In the volume method, the calculation formula for the extruded length of the aluminum rod is (aluminum rod length / upsetting coefficient - residual thickness) * extrusion ratio, and the rod length is (extruded length / extrusion ratio + residual thickness) * upsetting coefficient, where the upsetting coefficient is obtained by dividing the cross-sectional area of the cast rod by the cross-sectional area of the extrusion cylinder.

If the aluminum rod parameters are calculated using the practical weight method, it is: aluminum rod weight = extruded length * profile weight per meter + residual weight. Therefore, these two have different calculation formulas, and the above conclusion is drawn.
