Risers and Riser Design Riser must be separated from the casting upon completion so the connection area must be as small as possible Figure 11-13 Schematic of a sand casting mold, showing a) an open-type top riser and b) a blind-type side riser. The side riser is a live riser, receiving the last hot metal to enter the mold.
The sand casting process involves the use of a furnace, metal, pattern, and sand mold. The metal is melted in the furnace and then ladled and poured into the cavity of the sand mold, which is formed by the pattern. The sand mold separates along a parting line and the solidified casting can be removed.
Free, printable casting design guidelines pdf. Download now. 1. Wall Thickness. We recommend a wall thickness of at least 0.180 inches. Since permanent mold castings are gravity-fed and aluminum solidifies quickly, this ensure proper metal flow and solidification during casting. Avoid isolated thin or thick sections.

Sand casting process; In this type of casting, liquid molten metal is poured into the casting mold of the desired shape and allowed to solidify. The solid metal is then removed by breaking the mold. ... Based on the casting design guidelines, wall thickness is a vital parameter you should pay close attention to. Thin wall sections often lead to ...
Investment Casting Design Considerations. Size and Weight. Part size and weight are the most critical factors in determining part cost because mold capacity is limited by both size and weight. The more pieces that can run on a mold, the lower the part cost. Our design team will work with you to remove any unnecessary mass in an effort to …
Design considerations. Location of the parting line/plane. By properly locating the parting plane. The number of cores can be reduced. The gating can be made less elaborate. The material wasted can be reduced. The dimensional accuracy can be increased. Use of uniform thicknesses in a casting, where possible.
