What is the on-site inspection method for aluminum alloy die-casting molds? With the development of molds, aluminum alloy die-casting has become one of the most competitive molds. Testing aluminum alloy molds is a very important process before mass production of products, as defects in the molds can easily lead to large-scale losses. Therefore, manufacturers will apply many testing methods when inspecting molds at the factory. Today, the editor will give you a brief analysis.
The most commonly used testing method for aluminum alloy die-casting molds by our manufacturer is through dye testing. This detection method operates by utilizing the permeability of colored liquids. A highly permeable colored solution is sprayed onto the surface of the mold, which can easily enter the opening defects. At the same time, we dry the liquid layer on the surface as quickly as possible, and then spray the display onto the surface of the casting. After the residual penetrant in the opening defects is absorbed, the display agent is dyed, reflecting the shape, size, and distribution of the defects.
Aluminum die-casting molds must undergo testing before leaving the factory. Only by passing this standard can we put them into use. The qualification criteria for testing are divided into five aspects:
Firstly, the inspection standards and re inspection of aluminum alloy die-casting must meet the standards of GB/T15115. The chemical composition of the sample product can be selected from die-casting, meeting the requirements of GB/T15115; The mechanical properties, testing methods, frequency of testing, and testing standards in mechanical characteristics must meet the requirements of GB/T15115.
Secondly, the sample products used in aluminum die-casting molds, the size of the cut parts, and the testing experimental styles need to be determined through discussion.
Thirdly, the geometric styles of aluminum alloy die-casting inspection and testing can be tested by obtaining samples on a large scale or using the standards of GB2828 and GB2829 for testing experiments. The results of the testing experiments must meet the specifications.
Fourthly, the factory inspection of the appearance quality of aluminum alloy die-casting parts must be carried out one by one, and the inspection results must meet the requirements of this standard.
Fifth, the roughness of the surface of aluminum die-casting molds should be carried out according to the standard GB/T6060.1.
