Recently, the new national standard "General Technical Requirements for Precision Stamping Parts" has been officially implemented, which puts forward higher requirements for dimensional tolerances, surface quality, durability and other indicators of precision stamping series products. The reporter learned from the Municipal Quality Inspection Institute that the new standard has added bending strength testing and corrosion resistance testing items for ultra-thin sheet metal stamping parts.
Multiple companies have stated that they have upgraded their production equipment and adopted laser detection technology to control product accuracy. The Municipal Market Supervision Bureau will conduct special spot checks, focusing on whether precision stamping series products for electronics and automobiles meet the new standards. Experts remind that enterprises need to accelerate technological iteration to avoid losing market competitiveness due to substandard quality.
