Benefits of Aluminium Profiles  

Industrial aluminium profiles are profiles of aluminium shaped by the process of forcing it to flow through a shaped opening in a predesigned die. The extruded material emerges as an elongated piece with the same profile as the die opening. It is widely used in many industrial areas, it comes with the following benefits:

• Easy machining and fabrication
• Long life
• Excellent corrosion resistance
• Wide range of geometries possible
• Raw material cost is lower
• Eternal recyclable
• Good appearance, can be surface treated with different colors
• Good mechanical properties

How to choose the right alloy for extruded aluminium profiles?  

CHAL makes all the standard and custom aluminium alloys for extrusions. We can provide you with any tempers, shapes and sizes you wanted, by both direct extrusion and indirect extrusion. Both seamless and structure extrusions are available. If your demanded quantity exceeds 40 tons, we also have the ability to create a tailored alloy for you. Bellow table shows you typical alloy for aluminium extrusions.

Design a New Die for Your Aluminium Profile

A die also called a tool or mould. It is made of super-hard tool steels, and the hardness ensures it suitable for pressing aluminium material through inter opening. The process of pushing aluminium billet through a steel die to make the final aluminium profile is called extrusion. It determines the shapes of the profile, which is why different tools are used for the production of different aluminium profiles. For example, when we are making solid profiles, we choose a solid die and choose the built-up tool for making the hollow section profile. For making a large-sized aluminium extrusion, we design a die with one opening, and if making a smaller profile, we will create the die with multi chambers. You may find the die is the core part used in the manufacturing of aluminium extrusion.

How to start our cooperation (procedures)?  

1. First, send us your inquiry with technical details (drawing, alloy, temper, surface treatment, etc.)
2. We’ll make a feasibility study, give you suggestions and eventually quote for you.
3. If our offer is accepted, we will send you a final drawing to get your confirmation. Sign and stamp the drawing with your name and date.
4. Based on the approved drawing, we’ll design and make the die for extrusion. It takes about 7-20 days.
5. When the die is ready, we’ll perform a die trial, and send you a piece of a trial sample. It needs to be approved by the customer.
6. After you approve the trial sample, we will make it into the production schedule and start mass production accordingly. It will take about 1-2 weeks.
7. Inform customers and deliver on time.
