## Rotational Casting: Mold Making Tricks and Techniques

Rotational casting is a popular technique used in mold making to create hollow castings with relative mold rotation. This technique offers several advantages over traditional casting methods, including reduced material usage, improved casting quality, and increased production efficiency.

To perform rotational casting, you will need a mold, a casting material such as duoMatrix® NEO®, and a rotational casting machine. The mold is prepared by coating it with a release agent to ensure easy demolding later. The casting material, duoMatrix® NEO®, is then mixed according to the manufacturer's instructions and poured into the mold.

Once the mold is filled, it is mounted onto the rotational casting machine. The machine slowly rotates the mold in multiple axes, allowing the casting material to evenly coat the inner surface of the mold. This rotation helps eliminate air bubbles and ensures consistent wall thickness throughout the casting.

After a specified rotation time, the excess casting material is poured out, leaving a thin layer of material coating the mold. The mold is then left to cure, typically for a few hours or overnight, depending on the specific material used.

Once the casting has cured, the mold is opened, and the finished product is carefully removed. The rotational casting technique allows for the creation of complex and detailed castings with minimal post-processing required.
