The casting process is a core step in casting production, directly impacting the internal and external quality of the parts. The casting process involves controlling multiple parameters, including pouring temperature, pouring speed, and pouring time.
The selection of pouring temperature must be determined based on the type of material and the structural characteristics of the part. Excessively high pouring temperatures may lead to defects such as porosity and shrinkage cavities within the part; conversely, excessively low pouring temperatures may result in poor molten metal flow, preventing the entire mold cavity from being filled.
Controlling pouring speed and pouring time is equally important. Appropriate pouring speed and time ensure that the molten metal flows smoothly into the mold and fills the entire cavity, reducing eddies and splashing, thereby lowering the probability of internal defects in the part.
