Investment Cast Products
In the production of investment castings, the ceramic shell mold is first created with a wax master mold, then dewaxed by high-pressure steam and sintered in high temperature furnace, and then the metal pouring is completed in a vacuum system, and finally the key dimensions of castings will be precisely machined.
Fine surface roughness of the casting (Ra2.5)
Precise dimensional tolerance
Various alloys are available：
- Iron-based alloys (stainless steel, high-alloy cast iron, heat-resistant steel, duplex stainless steel…etc.)
- Nickel-based alloys (Inconel®, Monel®, Incoloy®, Hastelloy®… and other alloys)
- Cobalt-based alloys (Stellite®, HAYNES® series alloys)
- Customized alloy
Features
The melting process of nickel-based and cobalt-based superalloy materials is carried out in a vacuum environment. Not only can the cleanliness of molten metal and product quality be greatly improved, but it also provides a more comprehensive guarantee for the safety of operators and environmental protection.
The maximum size of the casting is about 500mm in diameter, and the maximum weight is about 100kg.
Applications
We provide various kinds of products, and the applicable industries include aerospace, petrochemical, energy, pharmaceutical…etc. Suitable material selection can be made according to the working environment, and there are corresponding solutions for extremely severe environments such as strong acid, strong alkali, high loading in high-temperature environment, high-temperature corrosion, high-temperature wear and even more complex environments.
