Overview

Perforated and slotted bolts present unique inspection challenges due to their non-standard shapes, multiple holes, and slotted head designs. Manual inspection is often inconsistent and time-consuming, especially when inspecting both dimensional accuracy and surface integrity.

This Perforated and Slotted Bolts Inspection Machine solves this problem with a fully automated, non-contact optical inspection system driven by AI. It performs both dimensional measurement and defect detection simultaneously, ensuring no defective bolts escape your production line.

Equipped with high-resolution cameras, industrial-grade lighting, and AI-based image recognition algorithms, it provides unmatched precision and repeatability, even in high-speed operations.
