The principle of extrusion is simple: A heated billet is pressed through a die with great force, and the finished profile emerges from the die in a manner that is not unlike piping icing through a pastry bag to decorate a cake.
The profile emerges at a speed of 5–50 meters per minute and reaches a length of 25–45 meters. Cooling takes place immediately, by air or water. To ensure that the profiles are straight and to release internal stresses, the profiles are stretched after cooling. At the same time, they are checked to ensure that all key functional dimensions are correct and that the surface quality is correct. The profiles are then cut to the appropriate length. The material is then subjected to natural aging or artificial aging to bring it to its permanent level of tensile strength.
ASE Profiles serve a wide range of industries.
With in-depth knowledge of the material, ASE ensure all customers get the optimum aluminum products for their requirements.
Sourcing standard or bespoke extrusions from ASE offers customers the benefits of time-savings, reduced costs, flexibility, finishing, design and engineering assistance, as well as the latest technological advances

Our expertise in designing profiles can be seen through the wide range of companies that we extrude for
From automotive parts, to greenhouses to firefighting equipment. They have just one thing in common. Our expertise in turning their designs into reality and producing quality extrusions time and time again.
We are able to offer our customers a complete solution for their aluminum needs with an extensive array of surface treatment and mechanical fabrication.
ASE have invested in the most modern equipment and the latest control systems, including long length profile machining centres and double mitre saws. Sapa can offer a vast array of fabrication and finishing services to turn your component into a finished product.
Milling machines for fabrication of aluminum have larger teeth pitches than equivalent tools for steel and therefore a more spacious groove for chips.
As with other sawing, a high cutting speed is required for a good result.
A high quality surface demands high power and stability in the tool and feed mechanism.
As with most machining, drilling should be carried out at a high speed. When using standard bits, they should be sharpened so as to reduce the pressure required and obtain a better result. Special bits for aluminum are only required for deep holes or soft alloys. It is important to note that the hole will be considerably larger than the bit diameter when drilling in aluminum, especially when drilling in soft alloys.
Aluminum can be turned in standard, special and automatic lathes and should be carried out at high speeds of rotation. Parts to be turned should therefore be fitted securely to avoid vibration. Spacers between the part and the mounting prevent marks on the metal and deformation.
Internal and external threads can be made using all available machining methods as well as through plastic deformation. Heat treatable alloys give especially high quality results. Taps for steel can be used for threads under 6 mm but special taps should be used for larger diameters.
Press work is normally carried out in eccentric presses with a cutting (shearing) tool. The press tools for aluminum are slightly different from those designed for other metals. Punch and die of hardened tool steel are recommended. Burrs are avoided by regularly sharpening the punch and die.
Aluminum's high coefficient of thermal conductivity is not so desirable in applications where low heat transfer is wanted such as in windows. There are many ways of insulating, two techniques that greatly reduce the ability to conduct are commonly used. In the first the extrusion is pressed in one piece and a closed space in the extrusion is filled with polyurethane. When the polyurethane has set, the extrusion is divided into two parts held together by the polyurethane. In this way the thermal bridge is interrupted (fill and mill).
In the other method two extrusions are joined using polypropylene or polyamide strips. These are rolled into position. This way of insulating makes it possible to use different colors on the inside and outside of the window.
Plastic Forming :
Aluminum extrusions can be bent using the same equipment as for other metals. Bending can take place with the hardened metal for larger radii but smaller ones usually require soft annealed or T4 (half-hardened) metal. It is possible to harden to full strength after bending. Bending should be carried out before anodizing if a complete anodized layer without cracks is required.
High shaping accuracy. The extrusion is held tightly at both ends and the shaping takes place by the tool moving.
Stretch forming :
With or without internal and external supports. The extrusion is held tightly and rotates with the tool. This method is suitable for small radii and can be repeatedly carried out.
Roller bending :
Used to bend extrusions with large radii. The extrusion is rolled between three wheels of which one is adjustable. It is possible to vary the radius on the same component using CNC-controlled machines.
Press bending :
Suitable for simpler operations in large batches. The parts are shaped in a two-part tool in, for example, an eccentric or hydraulic press or other simple equipment.
Turn your profile into a finished product
ASE today is just as much a knowledge company and an industrial partner, as an extruder of aluminum profiles. Often an aluminum profile is part of a larger whole, and has to work together with other components in a system. The earlier a customer brings us into a project, the more value we can add.
An ASE profile is often the result of a partnership between the customer's design department and out technical staff. But our job doesn't finish when the profile is extruded, processed and treated. As a complete industrial partner, we can turn your profile into a finished product – ready for shipping to wholesalers, retailers or directly to end customers.
A part of our customer's production chain.
ASE understands aluminum down to the tiniest detail. We have the most modern equipment and the latest control systems and tools. And we are constantly developing and refining our processing methods.
