The aluminum extrusion process can be done by direct extrusion and indirect extrusion. The direct extrusion process (also is called forward extrusion<\/b>) is the most common aluminum extrusion process for many aluminum extrusion manufacturers. But do you know about indirect extrusion (also is called backward extrusion, or reverse extrusion<\/b>)? Do you know some extrusion products must be produced by indirect extrusion? Let’s know more about the indirect extrusion process.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

What is indirect extrusion?<\/b><\/strong><\/h2>\n<\/div>

Normally, during extrusion billet is moved through the extrusion channel under pressure. During indirect extrusion processes<\/a>, the die is held constant as the billet moves with the container. For this to happen successfully, a stem is applied. One of the stem\u2019s properties is that it must be longer than the container moving with the die.<\/p>\n

The length of the stem will determine how long the final length of the product being extruded will be. Therefore, manufacturers decide the shape of an extrusion product by cutting the same on the stem. This way, both the extruded Aluminum and stem will share the same length thus determining how long your Aluminum extruded product is.<\/p>\n

For indirect extrusion to be complete, some requirements must be met. First, the billet must be preheated, although this is a requirement of all extrusion processes. This is then forwarded into the pressure chamber.<\/p>\n

Again, both direct and indirect extrusion processes happen under pressure. The movement happens as a hollow plunger pushes the billet through a hollow die. At the end of the stem, there\u2019s some blockage of sorts. This allows the billet to absorb pressure and travel back through the hollow die.<\/p>\n

As this happens, the billet assumes the shape of the die. The extruded Aluminum product that leaves the extrusion unit assumes the shape of the die!<\/p>\n

When making the decision about which extrusion process to choose, a lot is considered. The advantages of indirect extrusion are considered if one wants to settle for this process. The reverse is true.<\/p>\n

Manufacturers explore other extrusion options if their benefits outdo the indirect extrusion process, or if the disadvantages of this option are way too many. On that note, let\u2019s consider the advantages and disadvantages of indirect extrusion.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

What Aluminum extrusion products are made by indirect extrusion?<\/b><\/strong><\/h2>\n<\/div>

The aluminum extrusion product is used to make specific products due to the nature of the process. Besides, some products can only be best produced using this extrusion option. Here are some of the products that can be produced using this option.<\/p>\n
