As a leading provider of tungsten carbide tools in Switzerland, they have earned a reputation for their durability and precision. But what sets Graf Hartmetall apart from other suppliers? The secret lies in their mastery of the tungsten carbide sintering process. In this article, we will delve into intricacies of this process and explore how it unlocks a world of cutting-edge ceramic innovations.

The Importance of Tungsten Carbide Tools

Before we dive into the sintering process, it’s essential to understand why tungsten carbide tools are so highly regarded. Known for their exceptional hardness and resistance to wear, tungsten carbide tools are the go-to choice for industries that demand precision and durability. From aerospace engineering to automotive manufacturing, these tools play a crucial role in shaping our modern world.

Graf Hartmetall: Pioneers in Tungsten Carbide

Graf Hartmetall has established itself as a pioneer in the field of tungsten carbide tools. With a relentless focus on innovation and quality, they have become one of the leading suppliers in Switzerland and beyond. Combining cutting-edge technology with expert craftsmanship, Graf Hartmetall consistently delivers reliable and long-lasting tools to their customers.

The Tungsten Carbide Sintering Process

At the heart of Graf Hartmetall success lies the tungsten carbide sintering process. Let’s take a closer look at the key steps involved:

1. Powder Preparation

The process begins with the careful preparation of tungsten carbide powder. This powder is produced by combining tungsten metal and carbon in a precise ratio. The result is a fine powder with uniform particle size, ensuring a homogenous mixture during the subsequent steps.

2. Blending and Binder Addition

Next, the tungsten carbide powder is blended with a binder material, typically cobalt or nickel. This binder acts as a temporary adhesive, holding the powder particles together during the sintering process. The ratio of powder to binder is carefully controlled to achieve the desired properties of the final product.

3. Compaction

Once the powder and binder are thoroughly mixed, the resulting paste is ready for compaction. This step involves subjecting the paste to high pressure, typically through a pressing or extrusion process. Compaction ensures that the powder particles are tightly packed together, creating a dense and uniform structure.

4. Pre-sintering

After compaction, the formed shapes undergo pre-sintering. This step involves heating the compacted parts in a controlled atmosphere furnace. The heat causes the binder material to melt and diffuse into the surrounding powder, binding the particles together. The pre-sintering process helps remove any remaining porosity, resulting in a more structurally sound product.

5. Final Sintering

The final and most critical step in the tungsten carbide sintering process is the final sintering. This step involves heating the pre-sintered parts to a higher temperature, typically above the melting point of the binder material. As the temperature increases, the binder material fully liquifies and uniformly infiltrates the surrounding tungsten carbide particles. This process, known as liquid phase sintering, leads to the formation of a dense and cohesive ceramic material.
