Quality control methods and standards for hardware mold die casting mold manufacturing vary depending on the type and application of the hardware products. Some common quality control methods and standards are: dimensional analysis, which checks the size and shape of the hardware products against the design specifications, surface roughness testing, which measures the smoothness and texture of the hardware products’ surface, hardness testing, which evaluates the resistance of the hardware products to deformation and indentation, corrosion testing, which assesses the durability of the hardware products in different environments and conditions, and functional testing, which verifies the functionality and usability of the hardware products.
