Solid Tungsten Carbide Shaping Tools

At WELSCH, our shaping tools represent the pinnacle of powder-metallurgy. We utilize a two-phase material system where a specialized hard carbide phase is embedded within a metallic binder. This combination allows us to engineer tools that possess maximum wear resistance while maintaining the fracture toughness required to survive the high-impact environment of 150 TPM extrusion.

We "Surgically" apply our high-performance carbides to the critical contact points of the extrusion process, ensuring that the profile of the tile remains consistent from the first pallet to the last. Our specialized carbide range includes:

Roller Segments & Side-Roller Discs: Precision-engineered for rotational durability and edge retention.

Slipper Inserts & Side-Slipper Bodies: Optimized for low-friction surface finishing and structural longevity.

Hard Metal Slipper "Skins": Specialized carbide shielding designed to protect the forming head from extreme abrasive wear.

The Hard Phase: We primarily utilize Tungsten Carbide (WC), supplemented by high-performance carbides such as Titanium (TiC), Tantalum (TaC), and Chromium (CrC) to achieve maximum surface hardness.

The Metallic Binder: We utilize Cobalt (Co) as the primary binder phase. This metallic "glue" provides the critical toughness and electrical/thermal conductivity that distinguishes our cemented carbides from brittle ceramics.

We categorize our materials according to the strict recommendations of the Powder Metallurgy Association, allowing us to match the grain structure to the abrasive profile of your concrete aggregates: Nano (less than 0.2 um), Ultrafine (0.2-0.5 um, K06-K30), Submicron (0.5-0.8 um, K10-K50), Fine (0.8-1.3 um, K10-K50), Medium (1.3-2.5 um, K06-K60 / G05-G40), Coarse (2.5-6 um, K70 / G50-G55), and Extracoarse (greater than 6 um, B10-B45).

With a comprehensive and strategically managed inventory of premium cemented metal products, WELSCH demonstrates the highest level of availability in the industry. Our expertise in grain-size selection, from Nano to Extra-Coarse, is the foundation of the long-term, trusting partnerships we share with our global customers.
