How to Increase the Service Life of Shaped Drawing Dies?

Changzhou Shen Litong Mould Co., Ltd., a professional manufacturer specializing in high-precision shaped drawing dies and wire drawing dies, is often asked by global customers:

“How can we extend the service life of our shaped drawing dies and reduce production costs?”

Here are the most effective, proven methods based on our 15+ years of experience in the industry.

1. Choose the Right Die Material

The foundation of long die life starts with material selection:

 

For standard applications: Use high-quality Tungsten Carbide (YG6, YG8, YG15).

For high-speed or high-hardness wire drawing: Recommend Imported carbide or Polycrystalline Diamond (PCD) dies.

For special shaped drawing: CVD coated carbide or Nano-coated dies can significantly improve wear resistance.

 

2. Optimize Die Design and Manufacturing Precision

 

Ensure smooth transition angles and proper reduction ratio in the die profile.

Maintain excellent surface finish (Ra ≤ 0.05μm) in the bearing area.

Use advanced CNC grinding and polishing equipment to minimize micro-cracks and stress concentration.

 

At Shen Litong Mould, all shaped drawing dies are manufactured with high-precision equipment and undergo strict quality inspection before delivery.

3. Proper Installation and Alignment

 

Make sure the die is perfectly centered with the incoming wire.

Use high-quality die holders and avoid any misalignment, which causes uneven wear and premature failure.

Install vibration dampers if the drawing machine produces strong vibration.

 

4. Reasonable Drawing Process Parameters

 

Control drawing speed, reduction ratio per pass, and total reduction properly.

Avoid excessive single-pass reduction (generally recommended ≤ 20–25% for shaped dies).

Maintain proper lubrication – use high-quality drawing oil or powder with excellent cooling and lubricating properties.

Keep the wire temperature under control to prevent annealing effect and increased wear.

 

5. Regular Maintenance and Polishing

 

Clean the die regularly to remove metal powder and residue.

Perform timely polishing when signs of wear appear (usually every 50–200 tons depending on material).

Use professional diamond paste and ultrasonic cleaning for best results.

Replace or repair the die before severe wear occurs.

 

6. Storage and Handling Tips

 

Store dies in a dry, clean environment with rust protection.

Avoid impact or dropping during transportation and use.

Use dedicated die boxes for protection.
