FAQ of SSCD Dies

Relink combines top-grade CVD SSCD blanks with precision manufacturing (Taiwan-based), expert mirror polishing, full customization (geometry, angles, bearing lengths), and strong technical support. We focus on total ownership cost: longer/predictable life, fewer die changes, reduced scrap, stable performance, and dedicated service — delivering premium wire quality with synthetic reliability.

Standard steel or carbide casings:

• Ultra-fine: Ø25 × 6/8 mm.

• Fine: Ø25/28 × 8/10 mm. Custom options (tapered, flanged, special heights) fit all major drawing machines (high-speed, multi-head, single-head, etc.).

Yes — fully synthetic and man-made, so conflict-free, traceable, and compliant with global regulations (e.g., EU standards). No mined material means stable availability, consistent quality, and protection from natural diamond price volatility or shortages.

Due to uniform synthetic crystal structure and consistent blank dimensions, wear is predictable and recut performance is excellent. Most dies support 3–8+ high-quality recuts (depending on wear, size, and application). Relink provides professional recutting services to restore original specs, maximizing total die life and reducing costs.

• Standard tolerances: +0 / -0.0005 mm (ultra-fine <0.040 mm) to +0 / -0.003 mm (larger sizes).

• Tight/custom tolerances: Down to ±0.0004 mm or better.

• Ovality/roundness: Typically ≤1/3 of tolerance band.

• Mirror polish and smooth entry geometry ensure low friction, bright wire surfaces, and consistent roundness.

Relink SSCD dies are ideal for:

• Non-ferrous & precious: Copper, gold, silver, aluminum (especially bonding wire).

• Medical/high-precision: Stainless steel, titanium alloys, guide wires.

• Specialty: EDM wire, high-performance alloys, electronic conductors. Size range: 0.015 mm minimum to 1.5 mm+ (optimal for ultra-fine to medium-fine; custom larger available). They handle soft to medium-hard materials with excellent results.

Relink SSCD excels in ultra-fine wire drawing (0.015 mm – 0.80 mm) where superior surface finish, mirror polish (Ra < 0.02 µm), and tightest tolerances (±0.0004 mm or better) are required. PCD is polycrystalline (sintered diamond particles) and better for:

• Larger sizes, high-volume runs, or abrasive/hard materials (e.g., stainless steel, tungsten).

• Extremely long life in demanding conditions (often outlasting SSCD/ND in volume production). For bonding wire, medical wires, gold/silver, copper fine wires, and electronics — Relink SSCD provides brighter, cleaner surfaces and better precision than PCD.

Relink SSCD offers essentially the same exceptional hardness, thermal conductivity, and mirror-finish capability as natural diamond — but with major improvements:

• More consistent blank dimensions and material properties for predictable wear and recut performance.

• No natural defects (inclusions, cracks, cleavage planes) that cause variability in ND.

• Often 30%+ longer die life and more reliable recuts (typically 3–8+).

• Stable supply and pricing without scarcity or ethical concerns associated with natural diamonds. SSCD can replace ND in virtually all applications, especially where consistency and cost predictability matter.

SSCD stands for Synthetic Single Crystal Diamond (also known as SMCD, MCD, or synthetic monocrystalline diamond). It is a high-purity, man-made single crystal diamond produced using CVD (Chemical Vapor Deposition) under strictly controlled conditions. Relink uses premium-oriented SSCD blanks, which are free from inclusions, cracks, impurities, and natural variations found in mined diamonds.
