Plastic Inspection

JLI Plastic Inspection Systems are custom designed turnkey solutions for measuring dimensions, shapes and surface defects in many different plastic products.

Our systems cover a wide range of production processes such as injection and blow moulding, extrusion, thermomoulding, finish, assembly etc. All equipment is designed for the relevant environment. This may include adaption to your existing production, dedicated to any new machinery or as stand alone equipment for sampling.

General features/benefits of JLI turnkey systems include:

  • Adapted to existing production lines
  • Internet connection for support
  • Excellent reliability track records
  • Custom applications
  • Validation according to GAMP5 optional

Examples of Systems Commisioned by JLI

Plastic lid

Plastic Lid Inspection

JLI’s plastic lid inspection system is a compact and portable stand alone unit. The system is 2. generation and has been developed to meet the high demands for the pharmaceutical industry with regards to quality and validation.

  • High accuracy for visual imperfections, dimensional defects, fins and unfinished products
  • 21 CFR PART 11 compliant and complete validation
  • Fast changeover between different lid types
  • Built-in reject mechanism
  • Clever integration of illumination, and specially designed mirrors reducing the need for cameras
Plastic container

Plastic Container Inspection

The system can be used for any type of plastic container production, including injection blow moulding, and employ up to nine high resolution industrial area scan cameras. By using specially designed LED lighting inside the container the system is capable of inspecting an entire plastic container on both the inside and the outside while being rotated in front of a camera.

  • Fast changeover between different container types
  • Built-in reject mechanism
  • Containers are rotated in front of cameras
  • Clever and innovative integration of illumination
  • Trend analysis and statistical process control tool
  • Trends and statistics possible on cavity level

Plastic Plate & Folio Inspection

This vision system inspects immediately after production giving a fast response to production. If any discrepancies are detected, the system can activate a reject mechanism or marking equipment. Statistical data is gathered and enables operators to follow any developing deficiency of the production. The system is easily scalable with respect to plate/folio width, production speed and required tolerances. The system always detects surface defects such as:

  • Scratches
  • Groves
  • Discolorations

 

If the product is transparent or semi-transparent, the system also detects Inclusions in form of:

  • Air bubbles
  • Material deformations
  • Residues from a previous batch
  • Rolled in dirt
Plastic bag

Plastic Bag Inspection

The extrusion of plastic bags can be inspected for surface defects, dimensions, position and quality of the perforation etc. Our systems are designed for extremely high speed production and are scaleable.

  • Single camera operation
  • Camera installation on existing equipment
  • Can be customized for any product
  • Accuracy +/- 0.1mm
  • Line speeds up to 10m/s continuous motion
