Investment Castings FAQs
What is investment casting?
Investment casting, also known as lost-wax casting, uses a ceramic mold to produce metal components. Molten metal fills the mold, then cools and solidifies. The ceramic shell is removed to reveal the finished casting.
How does EQI evaluate my part before production?
We start with a Design for Manufacturing (DFM) review to assess your design and production requirements. This helps us identify opportunities to improve manufacturability while meeting your specifications.
How are wax patterns created?
We design and build a wax injection mold based on your part design. Wax is injected into the mold to create patterns that replicate the component. These patterns are then assembled onto a central structure called a tree.
How is the ceramic mold made?
The wax tree is repeatedly dipped in ceramic slurry and coated with sand to build a durable shell. Each layer dries before the next is applied.
What happens to the wax?
The ceramic shell is placed in an autoclave, where steam and pressure remove the wax. This leaves a hollow mold in the shape of your components.
How is the metal poured?
The ceramic mold is heated to prepare it for pouring. Molten metal is then introduced into the mold, filling the spaces left by the wax patterns.
How are parts removed from the mold?
Once the metal cools and solidifies, the ceramic shell is broken away. Individual components are then separated from the metal tree.
Will my investment-cast parts need machining?
Investment casting produces fine details and smooth surfaces, which can reduce the need for machining. When specific features require additional finishing, EQI can provide machining or grinding to deliver a complete component.
