The requirements for surface quality and precision will become increasingly higher
The perceived quality of a vehicle refers to consumers' subjective feelings and evaluations of the automobile product as a whole and in various aspects. It represents consumers' perceptual cognition of the product's quality. Among all factors, consumers value the exterior appearance of the entire vehicle the most when assessing its perceived quality. The quality of stamped parts is the most significant influence on the vehicle's exterior, affecting its visual presentation and consumers' judgments about the manufacturer's attention to detail. Achieving higher quality in automotive stamped parts, resulting in superior exterior quality and more refined styling, thereby enhancing the visual quality of the entire vehicle, is the future direction of automotive stamping technology development.
Surface quality and precision requirements will become increasingly high
The increasing demands for visual quality and refinement of the entire vehicle necessitate higher surface quality and precision. Surface quality must restore the lighting and shadow effects of the design, with clear edge lines. Due to inevitable issues in the forming process such as springback and creep, deformation is unavoidable, and minimizing this deformation has always been a challenge for stamping technicians. As the requirements for the quality of hemmed surfaces continue to rise, there is a trend towards fully drawing out the hemmed surfaces for the four doors and two hoods. Precision is the guarantee of gap, flushness, and assembly quality. Precision is also affected by springback and is not easy to control accurately. Currently, some automotive companies have raised the precision requirements for stamped parts, with some precisions already increased to ±0.3 and with further improvements expected. The quality of vehicle seams also has a significant impact on the visual perceived quality of the entire vehicle. If the seams of a vehicle are too large or uneven in width, or if there are large flushness differences or significant flushness variations on the outer panels on both sides of the seams, the vehicle will give off a sense of lower quality. In the field of stamping technology, the most important factors affecting the seam quality of the entire vehicle are the precision of stamped parts and the seam R-angle of outer panels. With the increasing demand for seam quality, smaller seam R-angles and smaller hemming gaps are required to achieve better hemming quality.
