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.

What needs to be measured in plastic film?

Looking at the plastic film industry from the point of view of an inspection supplier can be quite narrow. This article focuses on measurement requirements often ignored.

Plastic film defect segmentation

Roll defects versus film defects

There are so many sources of defects in plastic film processing. By  segmenting according to roll or film, root causes can be addressed. The  table below looks at providing an exhaustive list for the both blown and it can also be applied to cast processes also.

Why we do it?

As we design inspection systems for the plastics industries, I am always searching for great knowledge bases on the cause of defects and problems in the extrusion and printing processes. The goal for OneBoxVision is to provide information to our clients that will help them improve. I came across a great paper from LyondellBasell.  The following blog entry and supporting document is a mix of info from that white paper and some other sources. Hope you find it useful.
