Automated Pipe Fitting Vision Inspection & Packaging Line for Indonesian Injection Molding Factory

Project Overview

Production Workflow

1. Discharge from Injection Molding Machine

   
   

   Molded pipe fittings are discharged directly from the injection molding machine onto a conveyor belt, eliminating manual transfer and secondary contamination.
2. Conveyor Belt Feeding

   
   

   The conveyor belt transports parts steadily to the vibratory bowl feeder, matching the takt time of the injection molding machine and ensuring continuous upstream supply.
3. Vibratory Bowl Feeder Orientation

   
   

   The custom-engineered vibratory bowl feeder sorts and orients pipe fittings in a unified posture, feeding them one by one into the inspection station in a stable, orderly manner.
4. 8-Camera Vision Inspection System

   
   

   Parts enter the rotary-indexing inspection machine, where eight industrial cameras arranged at multiple angles capture full-surface images. The vision system inspects:

• Dimensional specifications (outer diameter, inner diameter, height, wall thickness)
• Appearance defects (scratches, burrs, flash, voids, discoloration, stains)
• Structural defects (short shot, deformation, cracks, gate residue)

5. Sorting & Packaging
   
   
   Qualified parts automatically flow into the downstream packaging machine for counting and bagging/boxing. Rejected (NG) parts are discharged separately through the dedicated NG outlet. Operators can simply clean or rework defective parts and feed them back into the line for re-inspection, minimizing material waste.

Key Technical Highlights

• 360° all-round inspection via 8 cameras with no blind spots on outer surface, inner wall and end faces
• High-speed inspection matching injection molding cycle, supporting 24/7 continuous operation
• Stable and repeatable detection accuracy, eliminating human eye fatigue and missed judgment
• Modular design, easy to integrate with existing injection molding and packaging equipment
• User-friendly HMI for parameter adjustment, production data statistics and defect type analysis

Customer Benefits

• Reduced manual inspection workforce and labor cost
• Improved product outgoing quality and lowered customer complaint rate
• Real-time production quality data traceable for process optimization
• Reduced scrap rate through cleanable and re-inspectable NG parts
• Enhanced production automation level and overall plant efficiency
