PET preforms color inspection system (PSIS)

is designed to enable automated preforms color stability check directly on the production line by which preforms are being transferred from the moulding machine to holding containers.

PSIS is a machine vision system which continuously trace images of manufactured preforms on-line, analyzes these images and provides the color of manufactured preforms and their color shift.

TYPES OF PET PREFORMS
PET PREFORM COLOR OF ANY EXISTING TYPE CAN BE MONITORED BY PSIS

Clear
preforms are transparent without a color.

Colored
light preforms with paint, but transparent to naked eye.

Dark
preforms that transmit natural light through one wall.

Opaque
preforms that do not transmit natural light at all.

A color discrepancy to be detected by PSIS system is assigned individually for each category, expressing it as a difference between the benchmark and non-conforming color.

FEATURES

Complete inspection of preforms with various shape, size, color; opaque, translucent, transparent

Integrated operation with control room of the factory

Easy integration into production line

User-friendly program interface

Robust, entirely industrial solution

Express inspection on the production line

Continuous work 24/7/365

Pre-defined profiles that are suitable for inspection of common types of PET preforms

ADVANTAGES

Maximization production line efficiency:

faster manufacturing with fewer defective products and lower labor costs.

Defect detection at the very beginning of production process:

defective preforms are immediately detect in early stage of production, thereby scaling down amount of works with obviously improper products.
