Heavy Duty Perforated Casting Flask, Stainless Steel, 4" x 5.7", Medium Size, Vacuum Casting, 1/8" Wall Thickness

For jewellery casters using the lost-wax vacuum method, this heavy-duty flask is a workshop essential. Its perforated design ensures an even vacuum draw through the investment, which is critical for a complete fill and a clean surface finish on precious metal castings.

Key features

• Perforated walls allow consistent vacuum pressure across the entire investment.
• Constructed from heavy-duty stainless steel with a 1/8" wall thickness for durability.
• Features a wide, solid flange for a secure seal against the vacuum table gasket.
• Sized at 4" x 5.7" to fit standard medium-scale jewellery vacuum casting machines.
• Designed for repeated heating and cooling cycles in a casting burnout kiln.

Who it's for

Built for professional UK jewellery makers, small-scale casting houses, and dental lab technicians who rely on vacuum-assist casting. It is suitable for casting precious metals like gold and silver, as well as non-precious alloys where a high-quality surface is required.
