What are the methods for on-site inspection of aluminum alloy die-casting molds?

What are the on-site inspection methods for aluminum alloy die-casting molds? 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; Before mass production, the inspection of aluminum alloy molds is a very important process, because if there are defects in aluminum alloy die-casting parts, it can easily cause losses in mass production.
Therefore, aluminum alloy die-casting manufacturers will use various inspection methods when conducting mold inspections on site. Today, Yuhuasheng Zinc Alloy Die Casting Manufacturer will give you a simple analysis:
The most commonly used inspection method for aluminum alloy die-casting molds by our manufacturer is color inspection; The inspection method is to utilize the permeability of colored liquids by spraying a highly permeable colored solution on the surface of the mold. The solution is prone to enter the opening defects, and at the same time, the liquid layer on the surface of the mold is wiped off. Spray the penetrant on the surface of the casting at the fastest speed, absorb the residual penetrant in the opening defects, and then dye the display agent to reflect the shape, size, and distribution of the defects.
Aluminum alloy die-casting molds must be inspected before leaving the factory. Only by passing this standard can we put it into use. The testing qualification standards are divided into five aspects:
1. The inspection standards and re inspection of aluminum alloy die-casting parts must comply with the GB/T15115 standard; The chemical composition of the sample product can be selected through die-casting, meeting the requirements of GB/T15115; Mechanical properties, testing methods, inspection frequency, and inspection specifications must comply with the requirements of GB/T15115.
2. The dimensions of the samples and cutting parts used in aluminum die-casting molds, as well as the design of experimental tests, must be discussed and decided upon.
3、 The geometric design testing of aluminum alloy die-casting parts can be carried out using large samples or GB2828 and GB2829 standards, and the test results must meet the requirements of the specifications.
4、 The appearance quality of aluminum alloy die-casting parts must be inspected one by one before leaving the factory, and the inspection results must meet the requirements of this standard.
5. The surface roughness of aluminum alloy die-casting molds shall be in accordance with the GB/T6060.1 standard.
