How to choose a suitable model of Aluminium extrusion press?
                                              –Aluminium extrusion press model selection tips

1. Confirm the target market (Architectural, building material for window and door, curtain wall, Industrial, Automotive)

2. Usually depend on the Max. Cross sectional dimensions. (Aluminium extrusion press model determines how large of an extrusion profile 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.)

3. If aluminum profile cross sectional is too complicated. For example, there are many the bucklings at the sectional layout, means the extrusion resistance will be larger, then need to consider larger model of aluminium extrusion press.

4. The aluminum alloy of aluminum billet. Usually the 6063 aluminium alloy is good for making the building aluminium profile for making window and door and curtain wall profiles. 6061 alloy is used for making for industrial profile. If it is other harder aluminium alloy, so it needs larger model aluminium extrusion press cause by bigger extrusion force.

5. Output and efficiency. If your desire aluminum profile output is large, then consider adopt one large aluminum extrusion press and one small aluminium extrusion press, large press for making the large profile and small press for making small profile. For example, if you want to making the output about 300T aluminium profile for window and door, then you can consider adopt one 600T press and one 1000T or 1250T press. 600T press is used for making the small aluminium window frame profile and 1000T or 1250T aluminium extrusion press for making the large aluminium door and window chute profile. Then you can improve the production efficiency. One set of aluminium profile for window and door includes some small aluminium profiles and some big aluminium profiles. If just use one 600T aluminium extruder, then you can make big aluminium profile; If you use 1000T aluminium extruder to make small aluminium profile, then you will pay 1000T production cost for small aluminium profile output. 

You also can use one production line for 1500T or 1800T. Muilti-pieces pieces small profiles can be extrued from one die at one time. But this production line request the following conditions: 1. Rich experience workers who know the aluminum profile extrusion process very well, and the die maintaining workers who good at die correcting after extrusion. 2. Good quality puller with fly saw. normal aluminum profiles for window and door, you can remove the puller, but muilti-pieces profile production, have to be equipped with puller and the quality must be good. 3. Die. Excellent die design for muilti-pieces profile extrusion also is very important, it can reduce the waste or failure when extrusion.

6. Thickess of aluminum profiles. In currently, with the aluminum profiles manufacture developping, more and more people adopt aluminum profile to decorate the floor, corner, edge of stair, wall and so on. So this aluminum profiles need to be made very thin and small can reach to 0.3mm. Thin aluminum profiles means high extrusion pressure, but if the aluminum extrusion press always in a high extrusion pressure working condition, will be very easy to damage the piston main pump and valve. How to make the thin aluminum profiles also keep the aluminum extrusion press in a stable performance, we need to consider about this problem. But some industry need the thick profiles, and some industry use the aluminum extrusion press to extrusion big billet to small aluminum bar to increase the density. So confirmation of  the thickness also is one of important of model selection factors.

7. The surface quality of aluminum profile: for example, if you need to produce the solar panel product, the surface quality requirment is very high, the tolerance is very strict (like ±0.15mm) . So the extrusion speed can not be fast, if extrusion speed is fast, the surface will be scratches on it, the aluminum profile will be unqualified. So before purchased the aluminum extrusion press, must talk to the dies manfaucture togehter, to check if dies manufacture and extrusion press manufacture can work together to offer you both. If you still worried, you can make a set of dies to trial at aluminum extrusion factory. For special aluminum profiles production, it must be confirm the dies manufacture togehter. 

8. Other extrusion. Big aluminium billet extrusion to small aluminium rod for increasing the density, like the glass table support and others industrial function. aluminium wire extrusion, one set of 600T aluminium extrusion press can extrude some pieces of aluminium wire by one time. It will be equipped with coil winder instead of handing table. Copper solid pipe extrusion. because the copper temperature is higher than aluminium and cool down easier than aluminium, so the extrusion speed is requested faster than aluminium extrusion press. so the extrusion press need to modify and add more motors. copper extrusion press will be equipped with the stainless steel table instead of felt belt handing table.

If you are not sure which model of aluminium extrusion press is suitable to you, we will give you good suggestion according to your aluminium profile cross sectional drawing.
