Relink’s SSCD Dies Feature

Relink is committed to delivering high-performance wire drawing solutions. We use premium SSCD (Synthetic Single Crystal Diamond) as the core material, fully replacing traditional natural diamond (ND), to provide customers with more consistent, efficient, and cost-effective drawing performance. Relink SSCD dies combine advanced CVD synthesis technology with precision machining processes, making them ideal for high-precision fine and ultra-fine wire drawing applications.

Key Feature & Advantages

• Exceptional Hardness & Wear Resistance SSCD offers extremely high purity and uniformity, free from the inclusions, cracks, or impurities commonly found in natural diamond. Its hardness matches or exceeds ND, delivering significantly longer service life (on average 30%+ longer than ND), greatly reducing die replacement frequency and machine downtime costs.

• Superior Thermal Stability & Thermal Conductivity The synthetic single-crystal structure ensures uniform heat distribution and excellent thermal conductivity. Even under high-speed, high-temperature drawing conditions, it maintains stability, minimizes thermal deformation risks, and enhances both die durability and wire surface quality consistency.

• Mirror-Finish Surface & Precise Size Control Relink SSCD dies undergo professional mirror polishing and feature optimized smooth entry geometry, resulting in extremely low friction coefficients. This produces wire with mirror-like bright surface finish, excellent roundness, and ultra-tight dimensional tolerances — especially suitable for demanding applications such as electronic wires, medical wires, and precious metal wires.

• High Consistency & Predictable Performance Compared to natural diamond, Relink SSCD blanks provide superior size consistency and more predictable recutting behavior, reducing quality variation and ensuring stable performance across every batch — helping customers maintain consistent production efficiency.

• Eco-Friendly & Supply Chain Stability SSCD is a man-made synthetic material with no conflict mineral concerns and full compliance with international standards such as EU supply chain regulations. Relink guarantees stable raw material supply, avoiding the price volatility and scarcity issues associated with natural diamond, delivering long-term reliable sourcing for customers.

• Wide Size Range & Customization Support Relink SSCD dies cover ultra-fine to medium-fine wire diameters (0.015 mm to 1.5 mm or larger, depending on application), with industry-leading tolerances (as tight as ±0.0004 mm). We offer both standard and fully customized geometries (entry angle, reduction angle, bearing length, etc.) to perfectly match various wire materials (copper, aluminum, gold, silver, stainless steel, special alloys, etc.) and drawing machines (high-speed / medium-speed / single-head / multi-head).

Application Areas

• Electronics industry: ultra-fine copper wire, aluminum wire, bonding wire

• Medical-grade wires: wires requiring extreme surface cleanliness and dimensional precision

• Precious metal wires: high-quality drawing of gold, silver, and other valuable materials

• Others: special alloy wires, fine stainless steel wires, and other high-precision requirements

Why Choose Relink SSCD?

Relink replaces traditional ND materials entirely with SSCD, giving you the consistent quality, longer service life, and superior cost-effectiveness of synthetic diamond — while maintaining (or even surpassing) the premium wire surface quality of natural diamond. Relink is more than a die supplier; we are your partner in improving drawing efficiency and optimizing total cost of ownership.
