Cast Bends

The casting process begins by fabricating a pattern in the same shape as the finished product will have. The patterns are normally made of a wax that is injected into the tooling. Once the wax pattern has been made, it is assembled with other wax pieces on a central stick to form a cluster.

The assembled wax structures are then immersed into a ceramic mix. After allowing the cluster to dry, it goes into a furnace for the dewaxing process. The remaining ceramic mold is now preheated to a specific temperature and filled with molten metal. Once this has cooled off, the mold shell is removed, creating the final product.

To meet industry’s strict quality standards, the castings go through rigorous testing. Cast bends are pressure tested and go through electrical batch testing.
