Pouring molten metal into three-dimensional molds to make metal parts is the basis behind both sand and investment casting. But there are significant differences between these two methods. In sand ...

The second process is used in the foundries for producing cast products. This is the oldest and simplest (in theory but not in practice) means of manufacturing shaped components. Other techniques, ...

Sand-casting metal parts is a technique that has been around for a very long time, but it can be educational to see the process from start to finish. That’s exactly what [Frederico] shows us with his ...

Today, gravity-fed permanent metal molds can produce near-net-shape parts from a variety of aluminum alloys. But it's up to the designer to makes sure it's both possible and profitable to use ...
