Description
Service Overview
SINO SEIKO（Sino Qtech Industries Co., Ltd.） provides professional PCD semi-finished die services, delivering precision pre-formed dies ready for final polishing and sizing. Our services cover the complete spectrum from PCD blank selection and carbide substrate preparation to pre-forming with tight dimensional tolerances — reducing your in-house processing time and ensuring consistent quality.
Working Principle
PCD semi-finished dies undergo precision grinding and electrical discharge machining (EDM) to create the preliminary die profile. The pre-formed die hole is machined to within 0.01mm of the final dimension, leaving only a minimal amount of material for final honing and polishing. This approach ensures that the final die achieves optimal surface finish (Ra ≤ 0.02μm) while maximizing the service life of your finishing tools.
| Parameter | Specification |
|---|---|
| Pre-Forming Tolerance | ±0.01 mm |
| Surface Finish (Pre-formed) | Ra ≤ 0.4 μm |
| Final Finish (After Polishing) | Ra ≤ 0.02 μm |
| Die Angle Accuracy | ±0.5° |
| Blank Diameter | Φ16 – Φ40 mm |
| Processing Methods | EDM, CNC Grinding, Laser Drilling |
| Lead Time | 7–15 working days |
Key Advantages
Receive dies ready for final finishing — skip the initial pre-forming stage in your workshop.
Factory-controlled pre-forming ensures dimensional consistency across every batch.
Reduce capital expenditure on pre-forming equipment and minimize material waste.
Applications
Wire drawing dies, tube drawing dies, bar drawing dies, and specialty profile dies for copper, aluminum, steel, and specialty alloy processing.
