In these images, you can observe the "hut" positioned over the crucible pot. Its purpose is to contain the SF6 gas (sulfur hexafluoride) used in magnesium die casting as a cover gas. This gas is pumped over the molten magnesium's surface to create a protective atmosphere, preventing it from reacting with oxygen in the air. To facilitate manual handling of the material to the shot cylinder, we must first remove the automatic ladling device. The "hut" has a trap door that is pneumatically activated by a foot pedal for this purpose.
While there are more automated and efficient methods for casting magnesium, Simalex's involvement in magnesium casting is limited. This is primarily due to the stringent safety requirements and the extended setup and teardown times associated with the process. Magnesium casting is provided more as a customer service to a select few clients who specifically request it. As such, we only undertake magnesium casting projects a few times per year.
