Abstract: This research paper presents the design and computational validation of a high-dimensional vacuum die casting chamber intended for the production of high-precision silicone and polyurethane components. The chamber, measuring 610 mm x 680 mm x 1270 mm, was modeled and analyzed using CAD tools and ANSYS simulation environments. Emphasis was placed on structural integrity under atmospheric pressure, air evacuation dynamics, and effective vacuum maintenance. CFD and static structural simulations were conducted to assess pressure distribution, velocity profiles, and von Mises stress values. Results demonstrate the chamber's capability to reach vacuum conditions under 70 Torrs within 7 minutes and maintain the vacuum for up to two hours, validating its ability for elastomeric material casting. To validate the physical design and assess assembly feasibility, a scaled 3D-printed prototype of the vacuum die casting system was fabricated.
