  • Shrinkage in Casting: Causes and Solutions - ThomasNet

    Shrinkage in Casting: Causes and Solutions. Fabrication shops and foundries attempt to create metal castings that closely adhere to design specifications with as few deviations as possible. However, avoiding defects in a product run can be a challenging task since most metals shrink to .

  • Health and Safety in Foundries Home Page

    Foundry processes can be divided into two types:- ferrous foundries and non-ferrous foundries (the latter usually work at a lower temperature). In any case they have the common process of pouring molten metal into a shape called a mould. This determines the outer configuration of whatever is being cast.

  • Sand Casting Process, Defects, Design

    Sand casting is able to make use of almost any alloy. An advantage of sand casting is the ability to cast materials with high melting temperatures, including steel, nickel, and titanium. The four most common materials that are used in sand casting are shown below, along with their melting temperatures.
