Qualified aluminum die casting of five criteria
Publish Time: 2016-06-16 Origin: Site
Machinery and equipment liquid steel in aluminum permanent rapid injection process, called aluminum die-casting process, the mold after cooling molding, high production efficiency and repeatable. With high efficiency, high precision, good surface quality, the subsequent processing of simple features. Prior to the factory for aluminum die casting for testing to ensure to be able to put to use are qualified products, the specific criteria:
1, on the aluminum die casting Testing in the way the chemical composition contains, must meet the GB / T15115 standards inspection and re-examination. Chemical composition of the sample contained in the product, and can be adopted from die-casting, meet T15115 / GB requirements; mechanical properties mechanical properties contained in, must meet the requirements of GB / T15115 in the detection methods, the frequency of testing and detection specification on.
2, aluminum die casting samples used in the product, after discussion decided to cut the size of parts, testing style.
3, a wide range of sample extraction or use GB2828 can die casting Testing geometric patterns, testing standard for GB2829, it must meet the specifications on the test results.
4, must be examined one by one before the appearance of quality aluminum die casting factory testing, we must meet the requirements in the standard on the test results.
5, to determine the roughness of the outer aluminum die casting according to the degree of roughness GB / T6060.1 standards.
These are the five rules for small series on aluminum die casting of qualified products standard summary, hoping to help to you.
