Shell moulding
The shell moulding process was originally developed by the German inventor Johannes Croning and has been reliably used in foundries around the world for more than 75 years. Even today, shell moulding is indispensable in the production of certain cast components, especially as it is so easy and delivers such high-precision castings.
About the shell moulding process
With the invention of the shell moulding process, Johannes Croning developed a new, stand-alone mould casting process based on an entirely new production principle, as well as an innovative resin-bonded moulding material for the production of castings. The biggest difference between this process, for which a patent application was filed in 1944, and the compact, box-bound mould casting processes was the shell- or mask-like reproduction of the outer contour of the casting mould, which is what gave the process its name.
Today, shell moulding is a technically mature, extensively tested production process for shell and core manufacturing. With regard to the dimensional accuracy of the resulting castings, the shell moulding process is still the most accurate sand-casting process in the foundry industry.
Hüttenes-Albertus offers foundries that use the shell moulding process a wide range of coating resins, finished sands and finished moulding materials.
