How to judge the quality of aluminum housing?

 The aluminum profile industry has become a very mature industry. The aluminum density is only 2.7g/cm. Although it is soft, it can be made into duralumin, hard aluminum, rust-proof aluminum, cast aluminum and other aluminum alloys. Nowadays, the application of aluminum housing is very extensive, let us see how to judge the quality of aluminum housing?

1. The text on the surface of the aluminum shell material is generally printed with imported inkjet codes. The text is clear, and the trademark identification, manufacturer, address, telephone, etc. are generally clearly marked. The text on the surface of the real fake aluminum veneer material is mostly printed by ordinary printing machines. Blur, its manufacturer, display etc.

2. The aluminum outer packaging material is made of high-quality raw materials, with high technical precision, and the surface and inner layers feel smooth and even.

3. The wall thickness of the aluminum shell is uniform, the aluminum veneer material is tightly combined, the quality and thickness of the aluminum sheet can reach the national standard. The wall thickness deviation of the fake and inferior products is large, the aluminum sheet is thin, and the aluminum veneer material has a large overlap gap.

  

4. High-quality aluminum housing can be used to measure the pressure resistance of aluminum veneer materials with a small pressure pump. The internal blasting pressure of real aluminum veneer is high, which can generally meet or exceed the requirements of relevant national regulations. Generally, the internal blasting pressure is low and it is difficult to meet the requirements of use.

The main alloying elements of the aluminum shell are magnesium and silicon, which are excellent in processability, weldability, extrudability and electroplating, corrosion resistance, toughness, easy to wear, color film, and anodizing effect. It is a typical extrusion alloy. . The high-quality aluminum shell is technically good. Using the first-processed coating process, the aluminum plate can be processed into complex geometric shapes such as planes, arcs, and spheres.

It needs the following four points for quality inspection

 

1. Display inspection: Whether the standard number and production license number of the product are marked on the aluminum profile and packaging.

 

2. Surface quality: The surface of the aluminum profile should be clean, and defects such as cracks, peeling, corrosion and bubbles are not allowed, and defects such as corrosion spots, electric burns, black spots, and oxide film shedding are not allowed.

 

3. Oxide film thickness: The oxide film of aluminum profile is formed during the anodizing process, which has protective and decorative effects and can be measured with an eddy current meter.

4. Sealing quality: After the aluminum profile is anodized, there are many voids left on the surface. If it is not sealed or not, the corrosion resistance of the aluminum profile will decrease. Commonly used methods of sealing quality inspection include acid leaching method, admittance method, phosphoric acid method.

What's the properties of POM?

  Polyformaldehyde (POM) thermoplastic crystalline polymer. Known as "Super Steel" or "Sai Steel", The English abbreviation is POM. Generally, polymers obtained by formaldehyde polymerization have a low degree of polymerization and are easily thermally depolymerized. It can be used as a raw material for organic chemicals and synthetic resins, and as a fumigant for drugs. 1.General property POM  is a hard, dense material with a smooth surface and gloss, light yellow or white, thin-walled partly translucent. Combustion characteristics are easy to burn, and continue to burn after leaving the ignition source. The flame is yellow at the upper end and blue at the lower end. Melting dripping occurs and has a strong pungent formaldehyde smell and fishy smell. POM is white powder, usually opaque, good coloring, specific gravity 1.41-1.43 g/cm3, molding shrinkage 1.2-3.0%, molding temperature 170-200℃, drying conditions 80-90℃ for 2 hours. POM's long-term heat resistance ...

There are several coloring methods for stainless steel parts

  There are several coloring methods for   st ainless steel parts 1. Electroplating Electroplating: The process of attaching a metal film to the surface of metal or other materials by electrolysis. It can prevent corrosion, improve wear resistance, electrical conductivity, reflectivity and enhance aesthetics.   2. Water plating It does not rely on external power supply in the aqueous solution, but only relies on the reducing agent in the plating solution to carry out the chemical reduction reaction, so that the metal ions are continuously reduced on the autocatalytic surface to form a metal plating layer.   3. Fluorocarbon paint Refers to coatings with fluororesin as the main film-forming substance, also known as fluorocarbon paint, fluorocoating, and fluororesin coating.   4. Spray paint The paint is sprayed into a mist with compressed air and applied to the stainless steel plate to form different colors.   Additional ： The current color stainless steel pl...

What is 'Catch hook and thin-wall' of plastic mold products?

What is 'Catch hook and thin-wall' of  plastic mold products ?​ 1. The Catch hook The catch surface and the amount of catch hook are the important basis for the test data during assembe.  Once made any tiny mistake about these numbers, It would become a huge mistake of the product. Therefore, during mould design, We needs to pay special attentin to the catch hook assembly and testing. 2. The thin-wall What is the big problem about thin wall? The binding point is particularly easy to press and brittle, Then could't pass the test. It will be difficult to assemble in the next step, The product will be uneven filling, shrink, and easy broken.
