Split Dies


Split dies are dies that are split in two halves in order for the die to be placed around the wire and bolted back together, without the need to re-string the wire through the die. Split dies are generally used in bunching and stranding machines where considerable effort and downtime are a consequence of using standard dies.

The typical blank of choice is tungsten carbide, generally larger than R5 (see tungsten carbide products for available blank sizes). Size appropriate PCD blanks may be used if your process requires. Contact one of our representatives to see which combination is best suited for your application.
