1. The surface of the aluminum alloy shell material is generally printed with imported barcodes, clear handwriting, trademark identification, manufacturer, detailed address, and even telephone universal identification. The surface of counterfeit and inferior aluminum veneer materials is mostly packaged and printed. The device is copied and the handwriting is blurry. Its manufacturer, logo, etc. Usually unknown or unmarked.
2. The aluminum alloy shell material is made of high-quality raw materials. High precision in processing technology. The surface and inner layer are smooth, even without black spots.
3. The aluminum shell thickness of the aluminum alloy shell processing plant is uniform, and the aluminum veneer material is tightly connected. The quality and thickness of aluminum plates exceed national industry standards. Although there is a significant thickness error in counterfeit products, the aluminum plate is too thin and the gaps between the aluminum veneer materials overlap. Very large.
4. High quality aluminum alloy casing can be used for testing the impact resistance of aluminum veneer materials in small and medium-sized pressure pumps. The actual engineering fracture working pressure of aluminum plates can generally exceed or exceed the requirements of relevant laws and regulations; Although the work pressure of counterfeit projects is generally low, aluminum shell processing plants cannot consider applying for regulations.
