Design and Machining of Tungsten Carbide Insert Powder Metallurgy Die & Pressing Tooling

Tungsten carbide insert pressing dies typically feature precision multi-stage buffer structures and quick-change die systems. Core components include upper punch, precision cavity die, lower punch plate, and multi-stage buffer ejection mechanisms. The die’s core components are machined by experienced engineers with tolerances up to ±0.002mm and surface finish polish up to RA0.05. Critical core components are manufactured from high-performance tungsten carbide, a material produced through powder metallurgy processes using refractory metal carbides and metal binders, achieving HRA hardness of 86 to 93, equivalent to 69 to 81 HRC. Additionally, it exhibits excellent heat resistance, maintaining hardness virtually unchanged at 500°C and retaining high hardness even at 1000°C, making it ideally suited for long-duration, high-load powder pressing operations.

Through optimized process design and high-performance die materials, a single set of dies can stably produce over 400,000 pieces, tripling the service life compared to conventional dies, with finished insert qualification rates exceeding 99%. Precision guide mechanisms and buffer systems ensure stable and reliable pressing processes, guaranteeing uniform density distribution and precise geometric dimensions in the pressed insert blanks.
