Cheap Custom Tungsten Carbide Stamping Die Parts Machining

Stamping dies are specialized equipment used in cold stamping processes, whereby materials (metal or non-metal) are fashioned into parts (or semi-finished products), and are referred to as cold stamping dies (commonly known as cold dies). Stamping involves applying pressure to the material at room temperature using dies mounted on a press, causing the material to either separate or undergo plastic deformation, thereby obtaining the desired part through a method of pressure processing.

Tungsten carbide, utilized for its superior hardness and wear resistance over any other type of mold steel, does have lower bending strength and toughness. Tungsten-cobalt tungsten carbide, which are used for dies that experience minimal impact but require high wear resistance, can be selected with a lower cobalt content. For dies that are subject to greater impacts, a higher cobalt content tungsten carbide is advisable.

Steel-bonded tungsten carbide are produced by adding a small amount of alloying element powders (such as chromium, molybdenum, tungsten, vanadium) to iron powder used as a binder, with titanium carbide or tungsten carbide serving as the hard phase, and are sintered using powder metallurgy methods. The matrix of steel-bonded tungsten carbide is steel, which overcomes the drawbacks of poor toughness and difficult machining typical of tungsten carbide. Steel-bonded tungsten carbide can be machined, welded, forged, and heat-treated. Although their hardness and wear resistance are lower than those of tungsten carbide, they still surpass other types of steel and can reach hardness levels of 68 to 73 HRC after quenching and tempering.
