Dear friends we are a holding investors company based on u a e - dubai right now we are interesting to build aluminium extrusion plant in some place in Africa ,we need full information about the…Continue
Hi,this is ,i am a engineer professional in prototyping and tooling in China.Hope we could learn more each other in here and also hope have an opportunity to work with you.
Please tell your experiences with different CAM software for the manufacturing of Aluminium Extrusion Dies. What are most important features of a CAM solution, which is used for the manufacturing of Extrusion Dies ? (for 2-, 3-, 4- and 5-Axis)
Standard Hole Shapes: In modern Die Design software solutions certain common port hole shapes can be categorized for automatic model creation. Here is an example of a automatic multi cavity function for rectangular port holes.
Traditionally "Bearing Lenghts" are defined on 2D drawings. To transfer them to 3D Model is a very time consuming work, which has to be done frequently by die designers. Modern softwares are capable of automating this task and saving tremendous design time. At the photo you see, how "ExtrusionPower" is handling this task, especially the automatic tapering and blend creations on side-faces are bringing great time savings.http://www.extrusionpower.com

Laina , one more . may bo Good .
Thank you Andrew. Teh site must be having a bad day. I keep getting an error message:

Thanks Laina for good first galance
Here, the cutting process and the next process in the press, but already giving opportunities element modeling in 3D.....
The steps in the extrusion process are as follows:
The next step is sawing. After extrusions have been stretched they are transferred to a saw table and cut to specific lengths. The cutting tolerance on saws is 1/8 inch or greater, depending on saw length. After the parts have been cut, they are loaded on a transportation device and moved into age ovens. Heat-treating or artificial aging hardens the metal by speeding the aging process in a controlled temperature environment for a set amount of time.
I have found wonderful material on this, that makes for a simple understanding.
Extrusion is defined as the process of shaping material, such as aluminum, by forcing it to flow through a shaped opening in a die. Extruded material emerges as an elongated piece with the same profile as the die opening. To aid in understanding the extrusion process think about a Play Doh Fun Factory and how it works. Think of the Fun Factory as the extrusion press, the handle as the ram, the shape bar as the die, and the Play Doh as the aluminum billet. The first step is to choose the desired shape and color. Think of the shape as the die which will be used and the color as the temper and alloy needed. Next, the Play Doh is inserted into the holding chamber and pressure is applied to the handle, which forces Play Doh through the shape. In an extrusion press, pressure is applied to the billet by the ram where the dummy block is attached to the end of the ram stem. When Play Doh begins to emerge, it has effectively been "extruded". The same principles apply to extrusions from aluminum billets but considerably more detailed and sophisticated technology are involved.Press size determines how large of an extrusion can be produced. Extrusion size is measured by its longest cross-sectional dimension, i.e. its fit within a circumscribing circle. A circumscribed circle is the smallest circle that will completely enclose the cross section of an extruded shape.The most important factor to remember in the extrusion process is temperature. Temperature is most critical because it gives aluminum desired characteristics such as hardness and finish.
