Automotive parts processing is a complex and diverse process that involves multiple processing techniques and technological processes. When processing automotive parts, in order to avoid cracking, the following measures can be taken: Strictly control material quality: ensure that the quality of the raw materials used is reliable and meets relevant standards. For critical components, material testing and chemical composition analysis should be conducted to ensure compliance with requirements and reduce the risk of cracking from the source. Optimiza procedura fabricationis: disvelope fluxum rationale procedentis et assecura ut singuli gradi stricto controlli sunt. For key process links that may cause cracking, Advanced process technology and equipment should be adopted to reduce the possibility of cracking.
