In automotive component manufacturing, the machining precision and mass production stability of seat hardware directly determine the assembly quality of complete vehicles. Combined with automotive industrial production standards, this article conducts an in-depth comparison of CNC machining and stamping molds in terms of cost, precision (±0.005 mm), efficiency and applicable scenarios, and proposes the optimal process selection strategy: CNC prototyping + stamping mass production.
In the manufacturing of auto parts, the machining precision, surface quality and mass production stability of automotive seat hardware (including seat frame brackets, adjustment slide fasteners, locking mechanisms, etc.) directly affect the assembly accuracy, operating feel and service life of entire vehicle seats.
Currently, the two mainstream manufacturing processes adopted in the industry are CNC machining (precision numerical cutting) and stamping mold processing (continuous/progressive die forming). Many seat Tier 1 suppliers often face difficulties in process selection during new product development and mass production phases. Based on automotive industry standards, this paper compares the pros, cons and applicable scenarios of the two processes in detail to deliver an accurate selection guide.
