Tungsten carbide inner diameter dies are widely used in inner diameter stretching processes, particularly for manufacturing metal components, pipes, and other products requiring precise inner diameter forming. In industries such as automotive, aerospace, and mechanical manufacturing, these dies provide reliable processing solutions.
Example Size Specifications: Φ86*Φ80*Φ56.45*Φ49.55-R1*21-C1*45
Custom specifications available to meet specific processing requirements
Performance Advantages
Enhanced Efficiency & Quality: Reduces friction coefficient and processing stress while improving surface hardness. Significantly extends mold service life, prevents product galling and straining, improves product quality, and eliminates the need for unloading, polishing, and reloading - boosting overall efficiency.
Advanced Surface Treatment: PVD coating technology effectively addresses common malfunctions caused by abrasive wear, corrosion, blending, and adhesion. This technology extends product service life by 5-8 times for applications like blanking, cold heading, and powder molding, while resolving issues in extension, drawing, and flanging dies.
Superior Coating Properties: TiCN coating features fine nano-particle microstructure combining high toughness, hardness, and oxidation resistance. Creates extremely lubricious surfaces with frictionless chip evacuation. TiN coating provides excellent surface brightness, low friction coefficient, high hardness, and strong oxidation resistance.
Versatile Application Benefits: Custom coating technologies for various molds (powder metallurgy, stamping, forming, stretching, forging) enhance hardness, wear resistance, corrosion resistance, heat resistance, and surface smoothness. Functions as a release film to improve appearance roughness, precision, and significantly extend mold service life.
