Oil and Gas
Our investment casting process is versatile, perfect for industries like the oil and gas sector where special alloys and smart metals are needed to withstand extreme conditions. We use modern investment casting techniques and surface treatments to produce complex components like valves and pumps that can withstand high temperatures and corrosive environments.

Marine and Shipbuilding
Investment casting plays a vital role when it comes to the marine and shipbuilding industry. Parts and equipment in this sector must be able to endure long-term exposure to highly corrosive salt water and extreme temperatures. Investment casting is the ideal solution for manufacturing corrosion-resistant components like propellers, engine parts, and marine hardware.
Equipment
Having the right equipment for the investment casting process is essential. At The Federal Group USA, we use state-of-the-art technology to ensure the success of every project. Below is just some of the investment casting equipment that we leverage:
- Specialized shell-making equipment
- Highly automated robotic molding machines
- Horizontal vacuum precision furnace
- Vertical vacuum precision furnace
- High-pressure gas quenching vacuum furnace
- Medium to high-volume production
- Reliable quality assurance equipment
Automation

We use the latest wax processing technology. Our semi-automatic wax injection machines allow us to make wax patterns quickly and reduce the time it takes to finish the project.
Our dewaxing machines quickly melt the pattern without cracking the ceramic shell. We use specialized equipment to pour the molten metal without creating air pockets, minimizing the risk of defects. A thorough quality assurance process follows.

Investment Castings vs. Sand Castings: Which Should I Choose?
Investment casting is not the only casting service that we provide. We also offer:
- Stainless steel investment casting
- Sand casting
- Rapid prototype casting
- Centrifugal casting
- Lost foam casting
- Permanent mold casting
- Die casting
The investment casting process is typically used to produce parts that need to be very precise. This casting process makes it possible to have thin walls and complex internal cavities.
The investment casting process provides you with finer details and a smoother surface finish than other casting techniques.
For example, the sand casting process uses a mixture of sand and clay to create a mold around a pattern of the final product. The mixture is more porous than the wax pattern used for investment casting, this means sand casting cannot create as intricate parts.
