Brass and Steel Type Dies :Brass Type is an economical, general-purpose type for marking most materials such as: books, leather, plastics, paper and wood. Brass type outwears softer alloy metals like zinc and lead and holds up well when stamping under heat and/or pressure. Brass type also produces a much crisper, cleaner mark than cheaper alloy types. Alloy type may be less money up front but in the end brass is a much wiser investment.Steel Type is unmatched in durability and is ideal for marking harder plastics or long production runs. Our steel type is made from hardened and tempered tool steel which keeps replacement costs to a minimum. Custom Logo Dies can be produced with any wording or design, in brass or steel, for stamping applications where your text remains constant. Our logo dies are typically made type high (.918” / 23.3mm) to fit in most standard type holders but can also be matched to any size to fit your present type holder.Magnesium Dies are also available for shorter production runs.
