Extruder plastic processing method and how much the aluminum profile can be stretched when cooled

1. Aluminum extruder processing method, is it a plastic processing method?In addition, is there any spare part for this extruder?

Aluminum extruder processing, from the professional point of view, it is to extrude the barrel of metal blank, so that it from the specific mold hole outflow, and then, to obtain the desired section shape and size of the product.So, from its definition, its processing method, is a plastic processing method.And this kind of extruder, there must be accessories, generally speaking, is a thimble, scale board and skateboard and so on.

2. In aluminum extruder, the parameters of aluminum rod are calculated by volume method and practical weight method. Is the calculation formula the same?

In aluminum extruder, there are two methods to calculate the parameters of aluminum rod, volume method and practical weight method, and their corresponding calculation formulas are not the same.In the volume method, the formula for calculating the extrusion length of aluminum rod is (length of aluminum rod/upsetting coefficient - residual thickness)* extrusion ratio, and the rod length is (extrusion length/extrusion ratio residual thickness)* upsetting coefficient, where the upsetting coefficient is obtained by dividing the sectional area of the cast rod by the sectional area of the extrusion cylinder.

The parameter of aluminum rod, which is calculated by practical weight method, is: aluminum rod weight = extrusion length * weight of profile meters.So, these two have different formulas and come to the conclusion.

3. In the operation of the aluminum extruder, whether to determine the length of the aluminum profile before stretching?

In the operation of aluminum alloy extruder, aluminum profile before stretching, is to determine the length of the material, and then determine the tensile rate, so that you can get the main chuck moving position.Under normal circumstances, the tensile rate of 6063T5 is 0.5% -- 1%, and that of 6061T6 is 0.8% -- 1.5%. If there are special circumstances, it shall be considered separately.

4. What determines the clamping mode of aluminum profiles?When the aluminum profile cooling to how much, aluminum extruder can begin to stretch work?

The aluminum profile clamping method to determine, from a professional perspective, is determined by the shape of the aluminum profile.If it is a large section hollow profile, then, can be inserted into the stretch pad block, but, to keep a sufficient clamping area, in case the extruder in the use of the process of problems.When the aluminum profile cooling to 50℃ below, the aluminum extruder can begin to stretch.
