PRANCE metalwork is a leading manufacturer of metal ceiling and facade systems.
A business manager understands that ensuring high-quality products requires strict control over the raw materials used. Aluminum panels, for instance, are made from aluminum alloy, which means that to produce excellent aluminum veneer products, it is crucial to select the right raw materials. In this article, we will discuss how to judge the quality of aluminum panel materials, building on the information provided by PRANCE, a reputable aluminum panel manufacturer.
One way to assess the quality of aluminum veneer is by visually inspecting and touching the surface characteristics, as well as the inner and outer layers of the material. Upon observation, genuine aluminum panel materials typically display clear surface labeling, printed with imported inkjet codes. The handwriting is legible, and critical details such as trademark identification, manufacturer information, address, and even contact number are easily identifiable. Conversely, the surface writings on counterfeit and inferior aluminum veneer materials are usually printed with ordinary printing machines, resulting in blurred handwriting. The manufacturer, logo, and other crucial markings are generally missing or indiscernible.
Another aspect to consider is the feel and texture of the aluminum panel. Authentic materials are constructed with high-quality raw materials and meticulous precision, resulting in a smooth and flawless surface without any spots or imperfections. On the other hand, fake aluminum veneer products, often produced with cost-cutting measures, tend to have a relatively lower quality. Consequently, the surface and inner layers may feel rough, and imperfections may be present.
A significant factor in determining the quality of aluminum veneer is the uniformity of wall thickness. Genuine aluminum panel materials exhibit consistent wall thickness, with tightly combined layers that adhere to relevant national standards for quality and thickness. In contrast, counterfeit and substandard products often have larger deviations in wall thickness, with thinner aluminum sheets and an insufficient overlap of aluminum veneer materials.
To further assess the authenticity of aluminum panel materials, one can conduct a burn test. By igniting the aluminum pipe with an open flame, true aluminum-plastic pipes will demonstrate a tight interface due to their production through ultrasonic lap welding or butt welding, mainly using hydrogen arc welding. This tight interface ensures that the aluminum sheets do not detach when exposed to flame. In contrast, counterfeit and inferior aluminum-plastic pipes, along with other combined pipes, have loose interfaces because the aluminum sheets are not properly welded. Consequently, the aluminum sheets will detach upon ignition.
In addition to the burn test, the use of pipe shears to cut the aluminum panel material into spiral strips can provide further insight into its quality. By peeling off the layers of aluminum veneer material and PE (polyethylene) layer by hand, one can discern the quality of the adhesion. Genuine aluminum-plastic pipes possess a 5-layer composite structure, with the aluminum layer and PE layer closely adhered to each other. This results in the aluminum panel material layer and the PE layer being difficult to separate when peeled. However, counterfeit and inferior products compromise on the quality of adhesion between the aluminum layer and the PE layer, making it effortless to peel them apart.
Lastly, using a small pressure pump to evaluate the pressure resistance of aluminum panel materials can provide crucial information about their quality. Genuine aluminum-plastic pipes exhibit high bursting internal pressure, which generally surpasses or meets the requirements of relevant national specifications. Conversely, fake and substandard products tend to have low or inadequate bursting internal pressure, making them unsuitable for their intended use.
In conclusion, by employing the aforementioned methods, one can effectively judge the quality of aluminum panel materials. By closely examining the surface characters, feeling for smoothness and uniformity, conducting burn and peel tests, and assessing pressure resistance, one can make informed decisions when selecting aluminum veneers for the production of high-quality aluminum panel products.
