Hopefully this site will help the casting designer, user and buyer get more out of the process. There are sections on foundry processes, casting design, tolerances of sand castings, quality assurance methods specific to foundries, an alloy selection guide for nonferrous sand casting alloys and a collection of metalcasting glossaries.
May 08, 2014· In this video we look at the key design considerations for sand castings: draft angles, maintaining constant thickness and machining allowance.
When two or more uniform sections intersect, they create a region of heavy cross-section, resulting in the problems mentioned earlier. One way to minimize this is to core the intersection by a hole, similar to a hub hole in a wheel with spokes.
American Foundry Society announces the launch of a redesigned, reimagined magazine for casting end-users, Casting Source, previously published as Metal Casting Design & Purchasing. Read more. Boost Your Problem-Solving Skills at Management & Development Summit. October 30, 2019.
Our highly experienced engineers use a Design for Die Casting (DFDC) methodology that optimizes casting manufacturability while preserving functionality; The gains from DFDC vary with each job depending on whether the initial design is casting-friendly or not, but our engineers routinely manage to cut total costs by 30% or more; Manufacturability

software can be used, in place of actual casting trials, to detect feeding and risering problems in a steel casting, the present rules still serve several important purposes: • Casting simulation does not provide the initial riser design for a casting; the present rules can be used to develop the first "trial" riser design.

3. Design Guidelines & Numerical Methods Design for sand casting rules prohibit multiple geometries such as sharps corners, figure 6 to prevent hot spots or other casting defects, figure 7 ,. To reduce the shrink defect induced by hot spots, rounded corners (fillets or radii) are introduced. Figure 6 Sharp angle geometry guideline 
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.
Foundry sand is high-quality uniform silica sand that is used to make molds and cores for ferrous and nonferrous metal castings. The metal casting industry annually uses an estimated 100 million tons of foundry sand for production. Over time, foundry sands physically degrade until they are no longer suitable for molds. Consequently, 9
Parting Line. The parting line is where the two halves of the die casting die meet on the part geometry. CAD draft analysis is a quick and powerful way to help design and view the parting line of a die cast part model.
Sand casting is the most popular casting process employed in industry because of its great geometric freedom capability and for its cost effectiveness. In this article, we provide design rules for optimal sand casting performance.
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.
Design Considerations in Metal Casting Mold and Gating System Design, Directional Solidification, and Troubleshooting In the previous sections we discussed the fundamental aspects of manufacturing parts by metal casting. We covered the creation of patterns, …
Designing for the process can shorten lead time, reduce costs and eliminate pain. If your design needs to break some of the guidelines above, we might be able to find another way to achieve the results you are looking for in how we design the mold or specify an alloy suited to the application. We welcome your call.
The of sand and/or metal cores broaden the flexibility Of sand and mold estings by allowing a hole or undercut to produced in a surface of a casting to the parting plane. Since the* are from the sand or metal mold there must be a clearance for place- ment Or movement.
