Heavy Duty Perforated Casting Flask, X-Large 5"" x 7"", Stainless Steel, 1/8"" Wall, Vacuum Casting

This extra-large perforated casting flask enables efficient vacuum casting of substantial jewellery trees for professional UK jewellers.

What it does

Designed for demanding production, this flask ensures consistent vacuum distribution across larger investment moulds thanks to its precisely spaced perforations. The robust 1/8-inch stainless steel wall construction withstands the thermal stresses of kiln burnout cycles without warping. Its substantial 5" x 7" internal volume accommodates significantly more components per casting pour, streamlining your workflow and increasing workshop output for complex or multi-piece designs.

How to use it

• Prepare your wax tree and place it centrally within the flask.
• Securely attach the flask to your vacuum casting machine.
• Pour investment, allow to set, and proceed with burnout and casting.

Who it's for

This flask is essential for professional jewellers, silversmiths, and small-scale production studios in the UK looking to expand their casting capacity. It replaces smaller flasks, allowing for more efficient casting of larger items or multiple components simultaneously, thereby reducing setup time and increasing throughput.
