Full-Process Inspection

Challenge

The automotive manufacturing sector faces stringent precision demands across multiple domains. Engine blocks and transmissions have complex surfaces with tight tolerances, while gear surface defects and brake pad flatness require precise detection. Sheet metal assembly struggles with gap control on large reflective parts like bumpers and doors, affecting measurement accuracy. Injection molding of automotive glass and interior components demands exact contour and optical property control, complicated by transparency challenges. There is a pressing need for an intelligent, full-process inspection system covering machining, sheet metal, and injection molding, enabling comprehensive dimensional control from core parts to interior and exterior panels. Automation and full-process data traceability are essential to meet the industry’s dual goals of efficiency and precision. Specialized solutions address unique materials such as reflective bumpers and transparent glass.
