Sand Casting Design Rules Pennsylvania State University
Vent Holes and Riser Placing 3.2. Shrinkage Shrinkage is a type of casting defect resulting due to formation of shrinkage cavity as such due to lack of design and insufficient feed metal. Shrinkage results due to formation of a closed loop at a specific point during solidification which creates a cavity because of absence of feed of molten metal. Shrinkage can be classified into three types as... Pipe clamps offered in this section are designed for support and attachment of pipe to structural members. A wide range of pipe clamps are available for various applications. Materials Carbon Steel is used in the manufacturing of riser and pipe clamps. Stainless Steel and other materials are available.

  • Types of Chills: Internal Chills and External Chills Riser design: 1. Risers help to feed liquid metal into the last portion of the casting. Proper placement of the risers on castings changes the way in which both the casting and riser(s) solidify such that the riser is the last to solidify. 2. When designed correctly, a casting that’s free of shrinkage will be produced because all the

  • If the riser is located on the casting then it is known as a top riser, but if it is located next to the casting it is known as a side riser. Top risers are advantageous because they take up less space in the flask than a side riser, plus they have a shorter feeding distance. If the riser is open to the atmosphere it is known as an open riser, but if the risers is completely contained in the
