Relink SSCD Dies Specifications
Relink provides high-precision SSCD (Synthetic Single Crystal Diamond) wire drawing dies engineered for superior consistency, extended life, and exceptional surface finish in fine and ultra-fine wire applications. Manufactured using premium CVD-grown synthetic single crystal diamond blanks, Relink SSCD dies offer predictable wear patterns, reliable recut potential, and tight dimensional control — fully replacing natural diamond while delivering enhanced stability and cost efficiency.
Size Range & Hole Diameter Specifications
Relink SSCD dies cover a broad spectrum optimized for ultra-fine to medium-fine wire drawing:
-
Minimum hole diameter: 0.015 mm
-
Maximum hole diameter: up to 1.5 mm (larger sizes available upon request for specific applications)
-
Standard coverage for high-precision needs: 0.015 mm – 0.80 mm (ideal for electronics, bonding wire, medical, and precious metals)
-
Extended range: 0.80 mm – 1.5 mm+ for special alloy and stainless steel wires

| > 0.800 | +0 / -0.0030 or custom | Custom | Consult for tight specs |
-
Ovality / Roundness: Typically ≤ 1/3 of tolerance band (e.g., ≤ 0.0003 mm for ultra-fine sizes)
-
Special tight tolerances: Available down to ±0.0004 mm or better upon request for bonding wire and medical applications
Standard Casing (Blank Holder) Specifications
Relink uses high-quality steel or carbide casings for durability and easy mounting:
| Hole Size Range (mm) | Standard Casing Dimensions (D × H mm) | Alternative Options |
|---|---|---|
| < 0.100 | Ø25 × 6 or Ø25 × 8 | Ø28 × 8 |
| 0.100 – 0.399 | Ø25 × 8 or Ø28 × 8 | Ø25 × 10 |
| 0.400 – 0.800 | Ø25 × 8 or Ø28 × 10 | Larger casings |
| > 0.800 | Ø28 × 10 or custom | Custom heights |
Custom casing sizes and shapes (e.g., tapered, special flanges) available to fit all major drawing machines.
