Vacuum casting is basically a casting process that is commonly used to generate all types of industrial parts and prototypes. Casting is a very reliable and flexible process which requires a high-quality master model. The master model can itself be the finished industrial part or can be created using stereolithography. Either way, it is very important that the master model is of the correct quality in terms of both its perfect dimension as well as appearance so that no error or issues are transferred to the part at the end of the vacuum casting process.
What Is The Process For Vacuum Casting?
The vacuum casting process starts by placing a two piece of silicon mold in a vacuum chamber. The mold piece is encapsulated in two parts of silicon mold rubber and then is cured at high temperature. When the mold gets cured, it is cut open, leaving a hollow space at the center that completely matches the dimensions of the mold. After this, the master mold is then placed in a vacuum chamber and the hollow center is stuffed with a designated material.
When the master mold is stuffed with the polyurethane material, it is sealed with the vacuum chamber so as to prevent any air bubbles from damaging the final industrial product. Lastly, the resin is cured in the oven and the silicon mold is then detached so that it can be utilized for creating industrial parts. Once it is removed, the final industrial part can further be designed, decorated and painted as per the user’s requirement.
