Automotive headlight airtightness electrical testing fixture

Description

This fixture is specifically designed for comprehensive testing of the airtightness and electrical properties of automotive lighting, and is compatible with multiple passenger and commercial vehicle models. It boasts a positioning accuracy of ±0.02mm and an airtightness leakage rate ≤10Pa/min, simultaneously performing seal testing and electrical continuity/insulation verification. Utilizing a high-strength aerospace-grade aluminum base material and a scratch-resistant sealing structure, its modular quick-change design improves testing efficiency by 40%. Compliant with ISO 21409 standards and IP67 protection requirements, it achieves non-destructive testing through pressure attenuation, significantly reducing missed detections and short-circuit defects. It is a core piece of equipment for efficient quality control in automotive lighting production lines.
