3" x 5" Perforated Casting Flask for Vacuum Casting, 304 Stainless Steel Flask with Flange and Rubber Sprue Base for Jewelry Making and Metal Cast

Features: Easy maintenance The 304 stainless surface and open perforation layout simplify post-cast cleaning, so residue and investment material , supporting repeated operation while minimizing maintenance downtime and corrosion risk. Ergonomic handling and workshop efficiency With its compact 3 x 5 inch footprint, manageable weight, and precision dimensions, the flask slots into constrained benchtop areas and many vacuum chambers, can be stacked or stored efficiently, and offers consistent placement and alignment for small-batch production workflows, improving overall workshop organization Specifications: Material: 304 stainless steel Color: silver Size: 3 x 5 inches Package includes: 1 x Perforated Casting Flask Notes: Manual measurement, please allow slight errors on size. The color may exist a slight difference due to different screen displays

• Precision Vacuum Casting: the perforated casting flask is engineered to facilitate uniform flow and suction of casting liquids under vacuum, allowing air to be evacuated evenly across the surface, which decrease bubble formation and casting defects and helps artisans reproduce intricate jewelry and small components with reliable detail and repeatability
• 304 Stainless Steel Construction: measuring approximately 3 x 5 inches and fabricated from 304 stainless steel, this sand casting flask tolerates high-temperature casting environments and corrosion during repeated heating cycles, ensuring dimensional stability and consistent performance across multiple pours and thermal processes
• Seamless Integration with Vacuum Systems: the vacuum flask's dimensions and rim profile are designed to fit snugly within standard vacuum chambers and casting setups, minimizing pressure loss at the interface so that suction remains steady throughout the pour, enabling controlled metal or resin flow and improved casting consistency for precision work
• Perforation Pattern Engineered for Uniform Air Evacuation: a carefully distributed array of perforations promotes optimal air circulation beneath , allowing trapped air to escape quickly and evenly; This controlled ventilation supports uniform metal or resin flow into delicate cavities and lowers the incidence of surface and internal voids
• Broad Applicability Across Casting Techniques: this perforated flask is applicable in a range of processes including investment casting, lost-wax casting, and sand casting, and accommodates a variety of casting materials; Its versatility makes it appropriate for jewelry fabrication, decorative art pieces, prototype components, and other small-scale metalworking projects
