PAI Micro-Nozzle Plate | Precision Milled with Ø0.15mm Holes for Industrial Automation

We successfully delivered a precision PAI micro-nozzle plate for an industrial automation equipment manufacturer. Machined from Torlon® 4203 PAI, this component features multiple precision-drilled micro-nozzle holes on a thin-profile milled plate. Each micro-hole functions as an integrated nozzle, ensuring consistent airflow and precise dispensing in high-cycle automation environments.

Project Overview

Key Technical Highlights

• Micro-Nozzle Hole Drilling: Achieved consistent hole diameters down to Ø0.15mm with burr-free edges and exceptional roundness, ensuring uniform airflow and dispensing accuracy.
• High-Precision Hole Positioning: Maintained ±0.01mm position tolerance between multiple micro-holes, critical for multi-channel dispensing applications.
• Thin-Plate Milling Expertise: Machined thin-profile PAI plates (as thin as 1.5mm) with tight flatness control, preventing warping during and after machining.
• Integrated Nozzle Design: Micro-holes function as nozzles directly within the plate, eliminating additional assembly and reducing potential leak points.
• PAI Material Advantages: Torlon® PAI offers exceptional dimensional stability, high temperature resistance, and chemical inertness — ideal for precision dispensing applications.
• Single-Setup Machining: Plate contour milling and micro-hole drilling completed in one operation, ensuring perfect geometric relationships between all features.

Quality Verification

100% inspection performed using ZEISS CMM with 1.2μm repeatability. Micro-hole diameters and positions verified via high-resolution vision measurement system. Flatness checked on granite surface plate. Airflow testing available upon request. Material certification and first-article inspection report provided with each batch.
