Poly Di® Polycrystalline
When die life and wire production efficiency take precedent over wire surface finish, consider a Poly Di wire die.
Poly-Di wire dies are manufactured with polycrystalline diamonds, a durable synthetic material with a highly polished surface finish that minimizes friction for an exceptional resistance to die wear, cracking and breakage.
You get significantly longer die life, excellent wire roundness and highly predictable die wear with a good wire surface finish.
0.050 mm – 15.00 mm
- Maximum die life provides highest production efficiency with less downtime.
- Available in a wide range of grain and blank sizes.
- Excellent resistance to die fracture and breakage
- Even, predictable die wear.
Nonferrous wire, especially larger sizes where demanding wear is a problem, but surface finish is less critical.
Aluminum wire, copper wire, stainless steel wire, tire cord, welding wire, galvanized steel wire and saw wire.
