As technology matures, machine vision suppliers need to provide systems that do more than simply detect and reject defective parts. Pressco Technology Inc. developed the INTELLISPEC™ Machine Vision System with this important distinction in mind. The product is a culmination of nearly two decades of experience in supplying high speed, on-line vision inspection equipment to the global food and beverage container industry.

However, technology advancements alone miss the mark unless they provide a benefit to the customer. Recognizing this simple yet significant concept, Pressco has incorporated features into the INTELLISPEC™ product designed to help customers solve process problems and reduce costs.

Indicator Values: the INTELLISPEC™ system can graphically display important process information. Several types of graphs are available, such as Pressco’s patented correlation technology, where defects are related to machine part components (cavity, transfer arms, spindles, liner guns, pockets, etc.). This feature significantly reduces troubleshooting time by clearly identifying which component is contributing to defective parts.

The system can also be configured to display critical dimensional information. For example, by monitoring gate offset distance, customers can correct process variations before defective containers are produced. The system also provides statistical information, such as mean, standard deviation, CPK and PCI data for each dimension.

Reduced Spoilage: the percentage of parts rejected by existing vision inspection systems can be as high as 1% of the product manufactured, with false rejects accounting for as many as 25% of all parts rejected. Reducing the number of false rejects has obvious financial benefits, and Pressco’s patented Chromapulse illumination technology enables the INTELLISPEC™ system to highlight and detect defects while drastically reducing the number of false rejects.

INTELLISPEC’s™ advanced algorithms also contribute to a reduction in false rejects because they are able to distinguish between one small defect (which can be allowed to pass) and several small defects (which can be rejected).
