Bleeder Screw Inspection Machine – Overview

Our optical sorting machine for bleeder screw is engineered to deliver next-level accuracy for automotive bleeder screws, cross-hole screws, and cone-type precision components. Built with high-resolution vision sensors and intelligent algorithms, it performs complete 360° inspection covering cross-hole presence, hole continuity testing, cone concentricity measurement, top-flat surface inspection, and outer body scanning. Every part is measured for cone angle, OD, major/minor diameter, part length, thread presence, and dimensional integrity—ensuring every screw meets OEM standards.

This advanced optical sorting machine for bleeder screw also detects critical surface defects like cone surface damage, head dents, thread cracks, burrs, shank marks, and bottom-surface imperfections. Whether the component is micro-turned, machined, or cone-shaped, the system guarantees reliable defect detection and true Zero-Defects Inspection. Its high-speed intelligent OK–NG dual-ejection mechanism maintains quality without slowing production.

Designed for fastener manufacturers and automotive suppliers, this optical sorting machine for bleeder screw delivers real value by reducing rejections, eliminating manual errors, and improving consistency across the entire production line. With unmatched versatility, speed, and reliability, it becomes a powerful asset for any facility aiming for flawless quality control.
