At present, people's requirement of automobiles tend to be high performance, low energy consumption and low pollution based on energy and environmental protection. There are two ways to realized that....
Surface treatment of aluminum alloy die casts can be classified into pre-treatment and post-treatment. Pre-treatment is used for removing oxide skins and oil so as to improve adhesion force of post-treatment...
7. Segregation Features: The chemical composition at the bottom and top of the crucible is uneven during the smelting process. The die casting part which solidifies first and the die casting part that...
4. Inclusions Features: Inclusions are particles, whose composition is different from that of the casting, formed on the surfaces of the die casting part or inside the casting due to the coating materials,...
1. Blowholes Features: First, the surfaces of the hole wall are relatively smooth with metallic luster. Second, blowholes are existing under the surfaces of the die casting parts individually or in groups....
We have X-ray inspections for die casts, and find some inner defects such as shrinkage cavities, blow holes and shrinkage porosity existing in die casts after die casts are manufactured. We put forward...
We believe that technical key points of lower cylinder blocks are mainly as the following according to experimental analyses. 1. Scientifically design gating systems of cylinder block die casts; inserts...
In recent years, energy saving and emission reduction has become the trend of the time and lightweight of automobile is also general trends. Under the background of the two trends, aluminum alloy materials...
1. Aluminum phosphating Guanidine nitrate has features of good water solubility, small amount and rapid film forming, which is an effective accelerator for aluminum phosphating. Fluoride can accelerate...
Characteristics of Aluminium Die Casting and Service Lives of Dies Is it a good idea to use aluminium for die casting products? Aluminum has advantages of high thermal and electrical conductivity,...
