Frequently Asked Questions

What is the difference between PCD and natural diamond dies?

PCD (Polycrystalline Diamond) is sintered diamond with high toughness and long life. Natural diamond offers the best surface finish but is more brittle. PCD is ideal for high-volume production.

Can you customize dies for special applications?

Yes, we offer full customization including hole geometry, angles, coatings, and materials for unique industrial needs.

What industries use your dies?

Our dies are used in wire & cable, automotive, aerospace, electronics, medical devices, and construction industries.

Do you provide technical documentation?

Yes, we provide detailed specs, application guides, and technical support for all products.
