In the wire drawing industry, encountering abnormal cracks in a die can be a major setback for production efficiency. As a professional supplier with 20 years of experience, we specialize in providing high-performance PCD and carbide drawing dies.
Today, we will dive deep into the causes of longitudinal (axial) cracks in PCD dies—a common pain point for many manufacturers.
A Case Study: Turning Concern into Trust
One of our Russian customers previously hesitated to purchase PCD dies because their previous supplier’s products failed prematurely due to longitudinal cracking. While common industry knowledge suggests that high wire strength or insufficient lubrication causes such cracks, this was not the case for him.
3 Hidden Causes of PCD Die Failure
When external factors like lubrication are ruled out, the root cause usually lies within the quality of the PCD die itself:
- Inherent Material Defects: Subpar diamond powder or impurities within the PCD structure can create internal stress points.
- Improper Particle-to-Aperture Ratio: Using small diamond particles for a large opening (aperture) can compromise the structural integrity of the die core under high pressure.
- Weak Sintered Metal Reinforcement: If the powder metal sintering process is inadequate, the reinforcing effect of the casing is diminished, leaving the PCD core vulnerable to axial splitting.
How We Ensure Stability and Performance
To prevent these issues, we take a proactive approach to manufacturing and selection:
- Scientific Matching: We select the ideal diamond particle size and aperture based specifically on the material strength of your drawing wire.
- Advanced Sintering: Our production process focuses heavily on the sintering of powder metals to ensure the PCD core is perfectly reinforced and stabilized.
- Customer-Centric Adjustments: Sometimes, a minor technical adjustment in the die geometry can lead to a massive improvement in production efficiency.
More Than Just Drawing Dies
With two decades of expertise, we understand that stability comes from truly understanding a customer’s processing environment. In addition to PCD and carbide drawing dies, our specialized portfolio for the wire industry includes:
- Tungsten Carbide Rollers: For high-speed rolling applications.
- Nail Production Tools: High-wear solutions for fastener manufacturing.
- Carbide Cold Heading Dies: Precision-engineered for impact resistance.
Our summary:
A simple “seller-seller relationship” can no longer meet industrial needs. We prefer to be your technical consultant. If you are facing mold cracking or other failure issues, don’t do it alone.
