The wax is melted (known as lost wax) and injected into a mold. As it cools, the wax becomes the form to be reproduced.
This method allows the creation of very complex and detailed metal alloy parts, which may or may not be highly alloyed.
The process can be manual or automated. The preferred method at Vestshell is automated since it eliminates the risk of human error. This helps us to achieve a perfect replica of the original mold.
All this means that the investment casting technique (compared to assembly, welding or forging) is the best option for high-end industries and the most demanding clients, for whom errors are not an option.
Before entrusting the casting of precision steel parts to a manufacturer, your responsibility as a buyer or engineer is to select the one that meets all your requirements.
We will invite you on a guided tour of Vestshell’s Montreal foundry to demonstrate the rigour of our investment casting process. You’ll have the chance to ask questions about each stage of the manufacturing process.
Each steel part resulting from precision casting goes through seven specific stages. During this process, N.D.T. testing is performed, depending on the part requirements and manufacturing complexity:
Any anomaly detected during any of these controls starts a correction process, and the time is taken to validate the conformity of the part.
In addition, costly inspection processes can often be reduced, given the quality and stability level of the procedure.
