At California Nanotechnologies (Cal Nano), precision, durability, and innovation come together to offer best-in-class solutions for materials engineering. Among our specialized capabilities, tungsten carbide dies stand out as a cornerstone of our advanced manufacturing services. Leveraging the exceptional material properties of tungsten carbide, we provide custom die solutions that support industries requiring the highest levels of performance in metal forming, shaping, and powder compaction.

What Are Tungsten Carbide Dies?

Tungsten carbide dies are industrial tools used for shaping, forming, and compacting metals and other hard materials. These dies are composed of tungsten carbide — a composite material made of tungsten and carbon atoms — renowned for its extreme hardness and resistance to wear, deformation, and high pressure.

At Cal Nano, we utilize this material to fabricate dies capable of handling even the most demanding industrial applications. Whether used for wire drawing, cold heading, powder compacting, or extrusion, our tungsten carbide dies deliver unmatched performance and longevity.

Why Choose Tungsten Carbide?

Tungsten carbide is an ideal choice for dies due to its unique combination of hardness, strength, and wear resistance. With a hardness second only to diamond, it resists deformation and abrasion under extreme mechanical loads, making it indispensable in high-pressure or high-friction environments.

Key Advantages:

• Exceptional wear resistance
• High compressive strength
• Resistance to deformation and cracking
• Dimensional stability under high loads
• Extended tool life and reduced downtime

These properties translate into significant cost savings, greater precision, and longer intervals between die replacements — all essential in high-volume or high-tolerance production environments.

Our Tungsten Carbide Die Services

At California Nanotechnologies, we offer comprehensive tungsten carbide die services, from initial design and material selection to final machining and inspection. Our processes are guided by precision engineering, backed by decades of experience in advanced materials and nanotechnology applications.

1. Custom Die Design and Fabrication

We work closely with clients to understand their specific requirements — whether that involves the drawing of metal wire, forming complex fasteners, or compacting powder into solid forms. Our team utilizes CAD and simulation tools to design dies that meet tight tolerances and ensure reliable performance.

2. CNC Machining and EDM

With advanced CNC machining and EDM (Electrical Discharge Machining) capabilities, we are able to achieve complex geometries and precision finishes that are often not possible with conventional methods. This allows us to tailor each die to the client’s application with micrometer-level accuracy.

3. Material Selection and Optimization

Not all tungsten carbide is the same. Based on the intended application, we help clients select the appropriate carbide grade — balancing factors such as hardness, toughness, and corrosion resistance — to optimize die life and performance.

4. Testing and Quality Assurance

Each die undergoes rigorous testing and inspection to ensure it meets customer specifications and industry standards. We use non-destructive testing, dimensional inspections, and wear analysis to ensure every die performs flawlessly from day one.

Applications Across Industries

Our tungsten carbide dies serve a wide range of industries where strength, reliability, and precision are critical.

🔩 Wire Drawing

Used to reduce the diameter of metal wires by drawing them through a series of progressively smaller dies. Our tungsten carbide dies ensure high-speed wire drawing with minimal wear, perfect for steel, copper, and aluminum wires.

⚙️ Cold Heading and Forming

In the production of fasteners such as bolts, rivets, and screws, tungsten carbide dies withstand the immense pressures of cold forming without cracking or distorting — enabling cost-effective, high-volume production.

🧪 Powder Compaction

For industries like automotive and aerospace, we design tungsten carbide dies used to compact metal powders into solid components before sintering. These dies offer the hardness and stability required to create high-strength parts with tight dimensional tolerances.

🏗️ Extrusion and Stamping

In shaping bars, rods, tubes, and profiles, tungsten carbide dies are essential for high-pressure extrusion and stamping applications. Their durability ensures consistent results even under continuous operation.

A Commitment to Innovation and Precision

As a company rooted in advanced materials science and nanotechnology, California Nanotechnologies takes a science-driven approach to die fabrication. Our work with tungsten carbide is informed by deep expertise in powder metallurgy, thermal analysis, and microstructural control — all of which enable us to deliver dies with superior performance characteristics.
