Uking Diamond’s SSCD (also abbreviated as SMCD, MCD, or Mono-Diamond) drawing dies are engineered under strictly controlled HPHT (High Pressure High Temperature) conditions. They are the premier choice for zero-defect continuous drafting of ultra-fine and fine filaments:

Fine Steel Wire Industry : High-tensile steel cords, tire cords, saw wires, and precision stainless steel wires.

Electronics & Photovoltaics: Ultra-fine copper wires, tinned copper wires, and advanced semiconductor cutting wires.

Precious Metal Micro-Drawing: Fine gold, silver, and platinum lines where stable geometric tolerances are critical.

Refractory Metal Filaments: High-temperature drawing of tungsten, molybdenum, and welding alloy wires.

Product Details

1. The Power of Controlled (111) Crystal Orientation

Every single crystal diamond blank selected for Uking’s SSCD drawing dies is synthesized under extreme, multi-stage calibrated laboratory environments. We strictly align the internal diamond core to the (111) crystal face orientation.

Because the (111) plane represents the atomic structure with the absolute highest packing density and hardness in the diamond lattice, our SSCD dies exhibit isotropic, predictable wear behavior. This eliminates the premature structural chipping common in poorly oriented single crystals, ensuring that your manufacturing line achieves consistent, long-run production campaigns.

2. Elimination of Defects for Stable, Zero-Error String-Up

Traditional or secondary-grade single-crystal tools often harbor microscopic internal stresses or volatile nitrogen impurity clusters that rupture under heavy drawing tension. Uking’s advanced laser-scanning inspection filters out any blanks with trace cracks or inclusion vectors.

Our proprietary nano-mirror inner channel polishing guarantees a perfectly smooth wire entry zone. This geometric optimization drastically lowers initial friction coefficient, prevents metal shaving generation, facilitates immediate string-up, and keeps the wire perfectly round even after severe operational mileage.

Key Features

Predictable & Stable Campaign Life: The ultra-high purity and flawless consistency of synthetic mono-crystals make your tooling replacement schedules 100% predictable, cutting unexpected machine downtime.

Flawless Nano-Mirror Surface Finish: Smooth entry and reduction zones eliminate scratching on delicate fine steel or electronics wires, ensuring an elite grade finish.

Exceptional Photothermal Dissipation: The ultra-high thermal conductivity swiftly removes localized frictional heat from the die core during high-speed continuous drawing, preventing premature thermal fatigue expansion.

Uncompromising Geometric Consistency: Manufactured via automated high-precision laser profiling, ensuring every single die in your bulk order delivers identical micron-level precision.
