Nowadays, more and more metal shells of
aluminum products are made of metal wire drawing technology, which can play a beautiful and anti-corrosive role. Make products both fashionable and technological. In aluminum wire drawing process, the anode processing special skin membrane technology, can make the
aluminum plate surface generating a contains the skin of the composition of the metal film layer, each tiny silk mark is visible, so radiant with fine hair gloss metallic matte.
Common problems and solutions of
aluminum sheet wire drawing.
1. Uneven drawing:
Product of many factors, the problem is one of the most common feeding
aluminum plate width size, positioning when drawing wire drawing operation in the roller wear is inconsistent, cause drawing different specifications of the plate edge location drawing texture depth uneven density. (solution: in the treatment of each batch of
aluminum sheet on the roller before batch production after maintenance, as well as the backup of a set of the roller, the production process of each production, 100-120, zhang replaced the roller location at a time, to avoid the roller edge wear.)
2. There is a difference between the pattern and the pattern:
The biggest factor is that the wire drawing equipment is not well controlled, which leads to a shallow grain. Moreover, after oxidation corrosion, the clarity of
brushed aluminum plate decreases again.
3. Surface sand of
aluminum plate:
Production line in the bath concentration is low, the temperature is too high dusting, two reasons cause this is human factors, is the production personnel did not monitoring in place to bath liquid bath concentration and temperature deviates from the standard process.
