The Origin of Molding or Moulding

The word comes from the Old French “moule”, meaning a form or cast. Over time, English adapted it into “mould”, referring to shaping materials like wood, plaster, or metal.

The spelling difference emerged due to the natural divergence between British and American English in the 18th and 19th centuries. American writers simplified spellings, dropping the “u” from many words like colour → color and mould → mold, giving us the now-standard American version, molding.
