Heavy Duty Perforated Casting Flask XX-Large, Stainless Steel, 5" x 8", Vacuum Casting, 1/8" Wall

This XX-large perforated casting flask is engineered for high-volume lost-wax casting, handling substantial jewellery trees with consistent vacuum integrity.

What it does

This robust flask facilitates efficient vacuum casting by allowing even air evacuation through its precisely spaced perforations. The substantial 1/8" thick stainless steel walls provide excellent heat retention, crucial for a smooth metal pour and complete burnout. Its generous 5" x 8" dimensions accommodate larger casting trees, maximising throughput for production runs. The solid, heavy top flange ensures a secure seal against your vacuum table gasket, preventing leaks and ensuring a reliable casting cycle.

How to use it

• Prepare your wax tree and investment as usual.
• Securely seat flask on vacuum table gasket.
• Pour molten metal and initiate vacuum cycle.

Who it's for

Essential for UK-based production jewellers, silversmiths, and trade casters demanding maximum capacity and efficiency. This flask replaces multiple smaller flasks in a high-output workflow, ideal for casting larger single pieces or limited-edition runs where scale is paramount.
