For UK jewellery casters running larger production batches, this heavy-duty flask accommodates bigger trees for more efficient vacuum casting. Its extra-large 5" x 7" volume allows for more components per pour, increasing your workshop's output whilst maintaining casting quality.

Key features

  • Extra-large 5-inch by 7-inch size for casting larger items or multiple-component trees.
  • Constructed from stainless steel with a solid 1/8-inch wall for durability during kiln burnout.
  • Evenly spaced perforations along the main body ensure consistent vacuum pull during casting.
  • Features a thick, solid flange at one end for a secure seal on the vacuum casting machine.
  • UK-stocked for immediate dispatch to your workshop.

Who it's for

Designed for professional jewellery casters and small-scale production studios in the UK who need to increase their casting capacity. Also suitable for educational departments and workshops teaching lost-wax casting techniques with larger, more complex pieces.
