Cast aluminum parts, low cost, technology is good, remelting renewable resources and energy saving, so the application and development of this material enduring.
Casting has excellent mechanical, physical properties, it can have a variety of strength, hardness, toughness with the overall performance, but also both one or more special properties, such as wear-resistant, high temperature and low temperature, corrosion-resistant .
Casting weight and size range is very wide, only a few grams of the lightest weight, most weight up to 400 tons, the thinnest wall thickness of 0.5 mm, the thickness of more than 1 meter length may be a few millimeters to ten meters, to meet the requirements of different industrial sectors.
Casting, it is necessary to control the quality of casting and testing. First to develop from the raw materials, auxiliary materials to each specific product process control and inspection codes and technical requirements. Of each process is strictly according to the technical rules and technical conditions for control and inspection. Finally, for quality inspection of finished castings. Detection methods to be equipped with a reasonable and appropriate testing personnel. The general appearance of the quality of castings can be used to determine the comparison specimens surface roughness of casting; surface cracks can be subtle coloring method, magnetic particle inspection method. Internal quality of the castings, can be audio, ultrasound, X-ray and other methods to check and judge.
