Product Description

Tungsten carbide cold heading dies are a common type of mold in industrial manufacturing, primarily used for producing various metal parts, especially small-diameter screws, nuts, and bolts. In order to meet the needs of high-speed production, cold mold needs to have characteristics such as high hardness, high strength, high wear resistance, and high crack resistance. Tungsten carbide material is an ideal material that can meet the requirements of cold stamping molds. Choosing appropriate mold materials can ensure the quality and service life of the mold, improve the production efficiency and economic benefits of the enterprise.

Features of Tungsten carbide cold heading die

  • High Impact Toughness & Strength: Designed to withstand strong impact forces (impact compressive stress > 2500 MPa) and bending stresses.
  • Excellent Wear Resistance: Resists severe impact friction, even at elevated surface temperatures (up to 300°C).
  • High Hardness (Surface): Punch hardness typically 60-62 HRC; Die hardness typically 58-60 HRC, providing a wear-resistant working surface.
  • Good Core Toughness: The core material possesses sufficient strength and toughness to resist fracture under impact loading.
  • Optimized Case Hardening Depth: Hardened layer depth is precisely controlled (1.5-4 mm) to balance wear resistance and prevent brittle fracture.
  • High Fatigue Strength: Resists failure under repeated cyclic loading during cold heading operations.
  • High Bending Strength: Withstands bending stresses caused by uneven billet end faces.
  • Good Fracture Toughness: Resists crack propagation under high-stress conditions.

Applications of Tungsten carbide cold heading die

Tungsten Carbide Cold Heading Dies are primarily used on cold heading machines to form metal parts without heating the workpiece. Key applications include:

  • Fastener Production: Forming screws, nuts, bolts, and other standard parts (cold heading, cold stamping, cold pressing).
  • Precision Stamping: Manufacturing small, high-precision components like watch parts, musical instrument spring plates, and small steel balls.
  • Impact-Resistant Forging Dies: Used in forging applications involving significant impact loads.
  • Deep Drawing/High Compression Forming: Stretching steel bars and pipes with high compression rates, forming battery cases, and toothpaste tubes.
  • Bearing Industry: Forming components for bearings.
  • Tool Manufacturing: Producing parts for tools.
  • Ammunition Components: Stamping bullets and shell casings.
  • Powder Compaction (Molding & Stamping): Molding and stamping various metal and non-metal powders.
  • Piercing: Creating holes in workpieces under high stress.
