Knock-Up Benches & Accessories


MARC manufactures a few types of Fire Assay Lead Button Knock-up Benches: Basic, Extracted with Basic Features and Extracted with a Few More Options.

  • Here the moulds are tipped over and the lead buttons cleaned and shaped using a chisel & hammer.  
  • The MARC Knock-Up Benches include a strengthened “anvil” for the hammering process as a standard feature – this allows for the use of a hammer on the button without too much force being passed onto the bench frame. 
  • Since there is risk of lead exposure in this process due to slag dust MARC strongly suggests the Extracted models.
