Why are high-precision molds so expensive? There are three main reasons: first, the material must be high-quality steel that is wear-resistant, corrosion-resistant and stable; second, high-precision CNC, EDM and other equipment are required; third, the processing process is complicated, requiring multiple mold trials and measurements with the help of high-precision testing equipment. These factors have pushed up the cost of molds, resulting in a corresponding increase in product prices.
