How to distinguish the quality of 1590XX 1790NS Cast Aluminum Enclosure

(Summary description)Nowadays, many electronic products, such as power bank, Bluetooth headset, etc., are basically quality 1590XX 1790NS Cast Aluminum Enclosure. The reason is that the quality 1590XX 1790NS Cast Aluminum Enclosure is easy to process, has high flexibility and high grade, which can effectively increase the added value of products. What is its forming process?

What is its forming process?

1590XX 1790NS Cast Aluminum Enclosure

Nowadays, a large number of aluminum shells are still formed by vehicles, which is due to the difficulty of making cold extrusion molds. It should be noted that the corners and threads of the machined aluminum alloy shell must be rounded to avoid sharp edges and burrs. At the same time, the knurling design of the connecting ring of the aluminum housing should try not to use the cloth pattern. For the plated parts processed by the cloth pattern knurling, corrosion will inevitably occur in the knurled part during the salt spray test of the coating. Relatively speaking, the corrosion degree of the straight-grained knurled connecting ring during salt spray inspection is much lighter.

The quality of quality 1590XX 1790NS Cast Aluminum Enclosure is good or bad, mainly depending on the quality of the aluminum profile. In fact, another important factor is the shape of the aluminum enclosure. The shape of the aluminum alloy casing determines the quality of the aluminum casing. How to distinguish the quality of the aluminum casing in normal applications?

1. Logo inspection: The text on the surface of the quality 1590XX 1790NS Cast Aluminum Enclosure is generally printed with imported inkjet codes. The text is clear, the trademark identification, manufacturer, address, telephone, etc. are generally clearly marked, and the text on the surface of the real fake aluminum veneer material is multi-purpose Ordinary printing machine printing, the text is blurred, its manufacturer, display, etc. are general.

2. Surface quality: quality 1590XX 1790NS Cast Aluminum Enclosure material is made of high-quality raw materials, with high technical precision, and the surface and inner layers feel smooth and uniform. In addition to the surface of the aluminum profile should be clean, no defects such as cracks, peeling, corrosion and bubbles are allowed, and no defects such as corrosion spots, electric burns, black spots, and oxide film shedding are allowed.

3. Oxide film thickness: high quality quality 1590XX 1790NS Cast Aluminum Enclosure can use a small pressure pump to measure the pressure resistance of aluminum veneer materials. The internal pressure of real aluminum veneer is high in blasting, which can generally meet or exceed the requirements of relevant national regulations. Generally, the internal pressure of blasting is low and it is difficult to meet the requirements of use. The oxide film of aluminum profile is formed in anodizing, which has protective and decorative effects and can be detected by an eddy current thickness gauge.

4. Sealing quality: quality 1590XX 1790NS Cast Aluminum Enclosure has many voids on the surface after anodization. If it is not sealed or the sealing is not good, the corrosion resistance of the aluminum profile will be reduced. The commonly used methods of sealing quality inspection are acid leaching, admittance method and phosphobutyric acid method. The acid leaching method is generally used in the on-site inspection, that is, the surface of the aluminum profile is scrubbed with acetone to remove oil and dust, and 50% nitric acid by volume is dropped on the surface and gently scrubbed. After 1 minute, the nitric acid is washed off with water, and then wiped Dry, drip a drop of medical purple medicine onto the surface, after 1 minute, wipe off the purple medicine and thoroughly clean the surface, carefully observe the traces left, the aluminum profile with poor sealing will leave obvious marks, the heavier the traces indicate the sealing quality The worse.
