Precision PAI Suction Nozzle | Micro Holes & Perpendicular Mounting for Automation

We successfully delivered a high-performance PAI (Polyamide-imide) suction nozzle for an advanced automation equipment manufacturer. Machined from Torlon® 4203 PAI, this component features micro suction holes and precision-machined mounting features with tight perpendicularity requirements. The design incorporates thin-wall sections with drilled mounting holes at right angles, ensuring secure fixation and reliable performance in high-cycle automation environments.

Project Overview

Key Technical Highlights

• Micro Suction Hole Drilling: Achieved consistent hole diameters down to Ø0.2mm with burr-free edges, ensuring reliable vacuum pickup of miniature components.
• Precision Perpendicularity Control: Maintained ≤0.02mm perpendicularity between mounting face and fixation holes, guaranteeing accurate nozzle positioning and repeatable performance.
• Thin-Wall + Drilled Hole Integration: Machined thin-wall sections with precision-drilled mounting holes at right angles, combining lightweight design with secure fixation.
• PAI Material Excellence: Torlon® PAI offers exceptional strength, stiffness, and wear resistance at elevated temperatures — ideal for high-cycle automation applications.
• Single-Setup Machining: All critical features — micro holes, mounting faces, and thin-wall sections — machined in one operation, ensuring perfect geometric relationships.

Quality Verification

100% inspection performed using ZEISS CMM with 1.2μm repeatability. Perpendicularity verified via optical comparison. Micro-hole diameters measured using non-contact vision measurement system. Material certification and first-article inspection report provided with each batch.
