How to reduce aluminium profile’s defective items caused of bending?

As we know, it would be unworthy if aluminium profile defected because of bending, but how to avoid it?

Extrusion Aligning:

Aligning is an important segment that maybe bend the profile, the worker who takes charge of aligning must pay more attention to the force: the strong force will make shape of the profile deformation, closing in and peeling, less force will cause the bending.

Movement after extrusion:

Moving the profile to next process is also very important, the profiles will be shifted into metal frames, please pay attention to: Is the profile large or small? Is it a tube or flat? Generally speaking, two ends of large profile and tube are not easy to bend compared with the small profile and flat. (large profile usually refer to the profile section diameter is more than 80 mm, and the thickness is more than 0.8 mm; on the contrary, it belongs to small profile). When we move the small piece (length more than 5 meters), it’s easy to bend carrying on both ends, so the correct way to carry it is from two ends to the center.

Pending to surface treatment:

The hardness of billets reaches the standard after aging, so the profile is less prone to bending. However pay attention when it hits the shelves, if lifting both ends of the profile, try to avoid fluctuation of upper and lower which could cause certain bending of the profile.

4 Advantages of T-slotted Aluminium Extrusion Frame

Whether you are assembling a large production line, installing automation equipment, or setting up a workbench for a production line, you may need a metal framework to install robotic parts, dispensers, or other automated assembly equipment. Many factory owners choose traditional welded steel structures to enhance their strength and durability. However, aluminum extrusion frames are becoming increasingly popular for several reasons. Hoonly Aluminium Extrusion Framework is a modular solution that consists of Aluminium extrusion profiles with a unique T-slot design, and series of specialized connectors & fasteners , which allows designer or purchaser to adjust the structure frame according to their own needs. Because the framework is aluminum, it often has a higher price tag than steel (actually less than stainless steel). But don't you found that aluminum extrusion frames offer distinct advantages over other material frames (such as wood, stainless steel) systems? 1,

Application of High Strength Aluminum in Automotive Industry

The huge growing world car ownership is great influencing people's work and life, but resulting a series of problems such as energy shortage, environmental pollution is also increasingly prominent. Light-weight, energy saving, environmental protection, safety, comfort and low cost become the target of each car manufacturer, especially in energy saving and environmental protection, which is the major problem for the sustainable development of the human relationship, energy conservation, and emissions reduction has become an urgent problem in the automotive industry. Light-weight of the automobile, which means on the premise of guarantee vehicle performance is not affected, auto-manufacturers should be targeted to reduce automobile weight, to ensure the safety and comfort, and meanwhile should not improve the cost. From the life cycle of the automobile products, a fuel consumption cost is the main part of the vehicle life cycle cost, which occupies 71% of the cycle costs. A

Overview of Chemical Polishing Aluminium, Electra-chemical Polishing Aluminium and Mechanical Polishing

The general engineering application of wrought aluminium alloy material or building aluminium profile is the process of the semi-finished product. Aluminium extrusion profile manufacturers are generally able to directly put the profiles into anodize production line for anodizing. The obtained anodized film has the good protective properties in many engineering applications, which basically achieves uniform appearance requirements. However, if mechanically polished aluminium work-piece is directly anodized, only the smooth anodize oxide film could be obtained, but fails to get the coating film of high reflective. Chemical polishing and electro-chemical polishing can give aluminium profile a very shiny surface, but in terms of polishing, chemical polishing (or electro-chemical polishing) are fundamentally different from mechanical polishing: Chemical polishing and electrochemical polishing, as an advanced finishing method, can remove slight mold marks and scratches on the surface
