Machine Vision-Based Preform Inspection Equipment

Our AI-Driven Preform Inspection System revolutionizes quality control for PET bottle manufacturing with advanced machine vision technology. Designed for high-speed production environments, this equipment performs 100% inline inspection of preforms at rates up to 8,000 units/hour with micron-level precision.

Core Technology:

• Multi-spectral imaging: 5MP CMOS cameras (x8) with coaxial LED illumination and polarizing filters

• Deep learning architecture: Convolutional Neural Networks (CNN) trained on 2M+ defect samples

• 3D profile analysis: Laser triangulation sensors (0.01mm resolution)

Key Inspection Capabilities:

1. Geometric dimension verification

   • Neck finish Ø tolerance: ±0.05mm

   • Weight deviation: ≤0.3%

   • Wall thickness variation: <5µm

2. Surface defect detection

   • Voids/cracks ≥15µm

   • Black specs ≥20µm

   • Stress marks (birefringence imaging)

3. Material integrity checks

   • IV value monitoring (NIR spectroscopy option)

   • Color consistency (ΔE<0.5)

Operational Advantages:

• Zero-touch rejection: Pneumatic sorting with <2ms latency

• Self-adaptive lighting: Automatic compensation for material translucency

• OEE optimization: Reduces scrap rate by 40% vs. manual inspection

Compliant with FDA GMP and ISBT 128 standards, the system features HMI with real-time SPC dashboards and comprehensive reporting (PDF/CSV). Optional cleanroom (ISO Class 7) and high-temperature (85°C) configurations available for stretch-blow molding lines.

Target Applications:
▶ Beverage preforms ▶ Pharmaceutical jars ▶ Chemical containers

Integrated with Industry 4.0 protocols (OPC UA, MQTT), this future-proof solution delivers >99.95% detection accuracy while eliminating human inspection costs.
