Tension on a web must be understood if using a machine vision system

Tension and the materials you produce make a difference to inspection systems. Another area where defects can be introduced into the inspection process is due to tension variation. This can happen where there is poor tension control, particularly when the tension is too low or due to the material properties of the web.

Learn how rollers and web handling affect your 100% inspection system’s performance

The following article explains the many reasons why rollers (idlers) and web material properties can adversely affect inspection performance especially for 100% print inspection. Let's understand exactly the effects of idlers and web paths on your vision system.

Vision systems used to improve a technical composite manufacturing process

Laboratory system to analyse plastic sheets for gels and carbons

US based manufacturer of technical composite materials required a system to verify the purity of its pellet production process. OneBoxVision built a system that could be used in the laboratory.  SheetFlow  was used to perform gel counting so as to measure the component quality of an advanced composite process. OneBoxVision designed the complete apparatus to secure the sample being inspected which includes a linear slide so as to automate the scanning process.  The project was build and delivered as a complete unit to the client, with calibration and test certification.

California based extruder uses SurfaceFlow to guarantee powder milk bag production

Plastic film extruder required multiple systems to inspect and track defects

A US plastic film client with multiple US locations  approached OneBoxVision with a challenge. The company was producing bags for powered milk. The goal was to inspect the film while being extruded on a blown film line and alert the operators in real time to carbon specks so that it can be corrected at source. The extruded plastic would then be shipped to a second site where the film would be used on an automated line producing bags. The client wanted us to check again and also allow the second plant to access the inspection data for the first process.

Surface inspection is now standard on plastic extrusion lines

Inspection is now standard in the plastic industry!

The modern extrusion and converting/laminating lines now use surface inspection systems as standard. Your customers demand 100% quality control.  All plastic film include some level of contaminates, arising from the production process or due to the nature of Polymers. Therefore gels are only a question of resolution. Extrusion and converting lines classify many defect types such as gels, black specs, fish eyes, holes, oil stains, insects, scratches, coating voids, air bubbles etc. These all originate from different issues but most all can have an impact on the further processing.

Inspection 4.0 for plastic film extruders

ASIX - Inspection 4.0 for plastic film

Industry 4.0 requirements are now a staple element of modern industrial automation solutions.For inspection systems this translated into the ability to conform to automation standards and integrate with historians while supplying real time data for analytics. To this end we have developed a complete video data archival capability that conforms to ISA 95 automation standards.

The different types of plastics

Plastics can be divided into two major categories:

1. Thermoset or thermosetting plastics. Once cooled and hardened, these plastics retain their shapes and cannot return to their original form. They are hard and durable. Thermosets can be used for auto parts, aircraft parts and tires. Examples include polyurethanes, polyesters, epoxy resins and phenolic resins.

2. Thermoplastics. Less rigid than thermosets, thermoplastics can soften upon heating and return to their original form. They are easily molded and extruded into films, fibers and packaging. Examples include polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).

A glossary on plastic packaging

Often terms are thrown out acronyms and mistakes are made. The following is a short glossary of terms used by the plastic film and packaging sectors when discussing processes and types of plastics.  If talking to a machine vision system provider that is providing an inspection solution , it's probably better to provide the longer description. Hope you find it useful.

100% inspection tool for process control

Often it's difficult in high speed manufacturing to get good feedback on what you would consider obvious issues. Opacity measurement, color reflectivity in plastic film processing, textiles, coating variations for converters, formation analysis for non woven inspection and other visual measurements that change during a long run are not normally measured in real time and 100% inspection vision systems usually target defects that are visually obvious, ignoring the slow moving process issues that cost you dearly in the long run.
