Wire Drawing Die Manufacturing Process.
Our manufacturing workflow is designed to control die geometry, dimensional accuracy, and surface quality throughout production. Depending on the die material and design, the process may include blank inspection, core mounting, bore preparation, internal profiling, polishing, and final quality checks..
01
Blank Selection
Rigorous screening of premium PCD, ND, and SSCD blanks to ensure structural integrity and thermal stability for demanding production lines.
02
Casing & Sintering
High-pressure mounting and sintering of the diamond blank into a robust steel casing to withstand extreme drawing forces without deformation.
03
Laser Piercing
Utilizing advanced laser technology to create the initial bore, ensuring optimal reduction angles for the specific wire material being drawn.
04
Ultrasonic Profiling
Precision shaping of the reduction zone and bearing length using ultrasonic equipment, creating perfectly smooth internal transitions.
05
Micro-Polishing & Sizing
Achieving pure cylindrical geometries and flawless surface finishes. We strictly eliminate any annular grooves that could compromise wire quality.
06
Microscopic QC
100% final inspection under high-magnification microscopes. Every die is verified to meet strict ±0.001mm tolerances before global shipment.
