The [aerospace](https://blog.therseruk.com/ceramic-cores-in-aerospace-ebook-guide) industry represents one of the most technologically advanced fields, encompassing the design, development, and manufacturing of aircraft and spacecraft. This sector plays a critical role in various areas, including transportation, defense, and exploration. It pushes the limits of engineering and science, demanding materials and technologies that can withstand extreme conditions such as high temperatures, mechanical stress, and radiation.

Therser can assist with the stages below:

Drying and Hardening:   
Once the ceramic shell is thick enough, it is dried and hardened to prepare for the   
wax removal stage. The integrity of this ceramic mold is crucial as it must withstand the molten metal's   
temperature during casting.

Wax Removal  
Dewaxing: The ceramic shell with the wax pattern inside is placed in an autoclave or a furnace, where high   
heat is applied to melt and drain away the wax. This leaves behind a hollow ceramic mold. This step must be   
carefully controlled to prevent the ceramic mold from cracking due to thermal stress.

What we offer

Continuous Kilns:   
These kilns are designed for mass production, where the ceramic cores move continuously through the   
kiln on a conveyor belt or rail system. Continuous kilns are highly efficient and can maintain very uniform temperature conditions, making them ideal for large-scale production where consistency is key.  
Batch Kilns:   
Batch kilns heat a single batch of ceramic cores at a time, making them suitable for smaller production runs   
or for cores that require special handling. These kilns offer greater flexibility in temperature and atmospheric control, which is crucial for high-precision aerospace components.  
[Electric Kilns](https://www.therseruk.com/kilns)  
:   
Electric kilns use electric heating elements to achieve high temperatures. They are known for their precise   
temperature control, which is crucial for achieving the specific properties required in ceramic cores. Electric kilns are often used in environments where reducing the introduction of combustion byproducts is critical.  
Gas Kilns:  
These kilns use natural gas or propane as a heat source. Gas kilns can reach higher temperatures than electric kilns and are often used for sintering ceramics that require very high heat. They can also be adjusted to create specific atmospheric conditions that affect the final properties of the ceramic.
