How can you minimize porosity and shrinkage in casting processes?
Casting is a widely used manufacturing process that involves pouring molten metal into a mold cavity and letting it solidify. However, casting defects such as porosity and shrinkage can affect the quality, performance, and appearance of the final product. Porosity is the presence of gas or air pockets in the metal, while shrinkage is the reduction in volume or dimension of the metal as it cools down. In this article, you will learn how to minimize porosity and shrinkage in casting processes by applying some practical tips and techniques.
