What is die casting?
What is die casting?. A mold is loaded into the die casting machine, and then aluminum or aluminum alloy heated in a liquid state is poured into the material inlet [...]
Analysis and Solution of Blowholes and Impurities in Aluminum Die Castings
The most effective method of using aluminum alloy die casting parts for steam holes and sand holes is to use a new ceramic filter material without using secondary nozzles to reduce impurities.
Paint and Coating for Die Casting Parts
To produce a good quality aluminum alloy die-casting, a lot of steps and processes are required, and no error can occur in every process. The brushing method of aluminum alloy die-casting painting and coating is also an important part of the die-casting surface quality.
What problems aluminum alloy die casting shrinkage will cause?
In the solidification process of the aluminum alloy molten metal, the shrinkage pores are generated due to the shrinkage of the volume or the lack of liquid metal in the final solidified portion. The uneven thickness of the casting or casting is locally overheated, resulting in slower solidification in one part and recessed surface in volume shrinkage. Due to the existence of pores and shrinkage holes, the aluminum alloy die-casting is troublesome for surface treatment. The holes may enter water. When baking is performed after painting and electroplating, the gas in the pores expands by heat, or the water in the pores may become vapor. Volume expansion, resulting in aluminum alloy die casting surface blistering, so in the production of appropriate methods to solve the causes of these defects.
