Product Description

Non-Magnetic Tungsten Carbide Ring Cavity Mold WC-Ni Alloy For High-Precision Compression & Sintering
Our Non-Magnetic Tungsten Carbide Ring Cavities are the ultimate core components for high-precision forming processes. Engineered from specialized WC-Ni (Tungsten Carbide-Nickel) alloy, these cavities deliver the perfect combination of absolute magnetic neutrality, extreme wear resistance, and exceptional thermal stability—critical for producing consistent, high-quality parts in demanding industries like electronics, advanced ceramics, and specialized powder metallurgy.
Core Technology: The Foundation of Flawless Molding
  • Absolute Non-Magnetic Integrity (µ < 1.002): Utilizing a nickel-based binder instead of cobalt, these cavities produce zero magnetic field interference. This is essential when molding parts for MRI components, sensitive electronics, or aerospace systems where residual magnetism is unacceptable. It also prevents magnetic attraction of fine metal powders during filling.
  • Unmatched Wear & Deformation Resistance: With a hardness of 90-92 HRA, WC-Ni provides phenomenal resistance to abrasive wear from powders (e.g., metal, ceramic, ferrite) and repeated ejection cycles. Its high compressive strength (>4000 MPa) ensures the cavity profile remains dimensionally stable under high compaction pressures (often 10+ tons), far outperforming tool steel.
  • Superior Thermal & Chemical Stability: The low thermal expansion coefficient ensures dimensional accuracy is maintained across the wide temperature ranges of sintering or curing processes. It also offers excellent resistance to chemical attack from binders and lubricants used in molding.

Target Applications
Industry / Process Problem Solved Why Our Cavity is Superior
Powder Metallurgy / MIM Wear during compaction of abrasive metal/ceramic powders leads to oversized parts and scrap. WC-Ni hardness extends mold life by 10-50x vs. steel, ensuring consistent part density and dimensions over millions of cycles.
Electronic Component Molding (e.g., Ferrites, Inductors) Magnetic steel molds can magnetize sensitive ferrite materials, degrading final component performance. Guaranteed non-magnetic property prevents part magnetization, crucial for inductors, transformers, and EMI shielding parts.
Precision Ceramic / Carbide Sintering Dimensional drift in steel cavities under high sintering temperatures. Superior thermal stability maintains precise tolerances through high-temperature cycles.
High-Pressure Composite Molding Cavity deformation under extreme pressure, causing flash and poor part geometry. Extremely high compressive strength resists deformation, ensuring clean, precise parts at every press.
Our Value Proposition: Your Partner in Precision Tooling
  • End-to-End Engineering Support: We work from your part print or CAD model to design and manufacture the optimal cavity, considering draft angles, shrinkage factors, and ejection strategy.
  • Advanced Manufacturing & Finishing: Utilizing CNC grinding, Wire EDM, and precision lapping/polishing, we create complex profiles and ultra-smooth surfaces for easy part release.
