Precision in Every Grain: The Extramet Manufacturing Process
At Extramet Products we know that true precision starts long before a machine ever touches the metal. It starts with a deep understanding of tungsten carbide itself. Our manufacturing process is a blend of advanced technology, old-school craftsmanship, and rigorous science.
From the moment raw powder enters our facility to the final polish on a finished part, we carefully manage every variable. The result? Consistent, high-performance components that give you the strength and wear resistance your industry relies on.
1. Raw Material Selection & Powder Prep
Great parts start with great ingredients. We begin by sourcing only high-quality tungsten and cobalt powders. We don’t take quality for granted—every batch is screened for purity and particle size consistency before it ever hits the blending line.
Our engineers formulate specific grades by balancing hardness and toughness, ensuring the material can survive extreme heat, pressure, and wear. Whether you need a precision cutting tool or a heavy-duty component for the oil and gas sector, we fine-tune the powder mixture to meet that exact need.
2. Pressing, Preforming & Sintering
Once our powder blend is perfected, we press it into blanks or preforms using specialized high-pressure molds. This stage is crucial for minimizing material waste and setting an accurate foundation for the machining to come.
The Transformation: The pressed blanks then enter our high-temperature furnaces. through a process called sintering, the powder particles fuse into a dense, solid structure. This is where the magic happens—controlled temperatures and atmospheres transform a fragile preform into fully hardened tungsten carbide. We carefully match sintering parameters to the specific grade, locking in the grain size and mechanical strength you expect.

3. Precision Tungsten Carbide Machining
After sintering, the real craftsmanship begins. Our machining services include CNC grinding, centerless grinding, surface finishing, and laser etching.
We don’t just “get close” to the numbers. We achieve extremely tight tolerances—often within ±0.0001 inches. This ensures that when you receive a part from Extramet, it fits your assembly perfectly the first time.
Custom Solutions
Need something that isn’t in a catalog? We specialize in the non-standard. Working directly from your CAD files, drawings, or even a rough prototype, we can produce custom components tailored to your exact application. From medical devices to automotive energy systems, we understand the nuances of your industry.

Grade Selection & Support
One size rarely fits all. We offer a wide spectrum of tungsten carbide grades (including EMT-100, EMT-207, EMT-210, EMT-412, and EMT-609).
- Fine-grain grades: Perfect for precision cutting tools.
- Coarser grades: Ideal for heavy-duty, wear-resistant components.
Not sure which one you need? Our team is here to help. We’ll explain how different grades perform under specific loads and temperatures to help you extend tool life and lower maintenance costs.
4. Finishing & Quality Assurance
Before any part leaves our facility, it is cleaned, polished, and rigorously inspected. We verify every dimension, finish, and marking against your specific requirements using precision gauges and optical systems.
Our ISO 9001:2015 certification isn’t just a badge—it’s a reflection of our commitment to consistency. When you open a box from Extramet, you’re looking at a clean, accurate component ready for immediate use.
