📌 Why Choose Preform Specialties & Carbide Metals?

Best For: Toolmakers requiring a mix of custom-shaped preforms and long extruded rods, specifically those looking for tight-tolerance blanks that reduce their own finishing workload.

  • Custom Molding & Extrusion: Operating as a unified facility, this supplier combines the strengths of two distinct entities: Preform Specialties (custom shapes) and Carbide Metals (extrusion). This integration allows them to handle diverse orders under one roof, from complex, pressed-to-shape preforms to extruded coolant rods in lengths up to 37 inches. The supply chain of customers needing both standard stock and engineered specials is simplified.
  • Precision "Green" Machining: They excel in machining carbide in its "green" (pre-sintered) state. Their skilled team can turn, drill, flute, and bore complex geometries before the material hardens. For the buyer, this means receiving a preform that is significantly closer to the final part shape, minimizing the expensive and time-consuming diamond grinding required at your end.
  • Advanced Sinter-HIP Technology: To ensure structural integrity, they utilize Sinter-HIP (Hot Isostatic Pressure) furnaces. This process combines vacuum sintering with high pressure to effectively minimize or eliminate internal porosity. The result is a denser, tougher carbide product with improved transverse rupture strength, ideal for applications involving extreme wear or heavy loading.
  • In-House Precision Grinding: Unlike suppliers who only provide rough blanks, PSI/CMI features a fully equipped on-site grind shop. Whether you need centerless grinding, surface grinding, or polishing, they can deliver finished tolerances as tight as .0002". This "finish-to-print" capability makes them a reliable partner for high-precision projects where accuracy is important.
