Color measurement of granules and pellets, colored and translucent

Free-flowing pellets, granulates and irregular bulk materials are an important part of the plastics manufacturing process. Plastics processing companies rely on the uniform supply of plastic pellets for further processing in extrusion.

The raw granulate is an irregular, colorless and possibly translucent sample that is tested before mixing with color additives. The colored masterbatches or compounds are then also measured. HunterLab offers the perfect support in quality assurance for this application with precise measurement technology and suitable accessories for inhomogeneous samples.

Our solutions for your products:

Agera

Color measurement “as the eye sees”
  • 0°/45° geometry

    This geometry according to DIN corresponds very precisely to the color impression that the human eye has of the sample.
  • Integrated camera

    The integrated camera helps to place the sample precisely and to save a photo with the measurement data.
  • Integrated QC software

    The EasyMatch QC Essentials quality control software is integrated into the device and provides all the required color indices and metrics.
Agera
  • Full spectrum + UV

    With an illumination range of 360-700 nm, the Agera is also suitable for measuring optically brightened samples.
  • Smart user interface

    Your measurement results can be easily transferred to existing LIMS or SPC systems.

  • Uncomplicated & precise

    Simple "one touch" measurement reduces training time, optimizes the workflow and increases your productivity.

Aeros

Laboratory device for measuring color and degree of browning

  • Non-contact measurement

    The sensor detects the sample without contact, without having to measure through plastic or glass.
  • Large surface area

    The rotating sample plate captures over 170 cm2 of the sample in 35 measurements in 7 seconds.
  • Integrated QC software

    The EasyMatch QC Essentials quality control software is integrated into the device and provides all the required color indices and metrics.
Aeros
  • Intelligent height adjustment

    The distance sensor automatically compensates for height differences in irregular samples.
  • Smart user interface

    Your measurement results can be easily transferred to existing LIMS or SPC systems.
  • Uncomplicated & precise

    Simple "one touch" measurement reduces training time, optimizes the workflow and increases your productivity.

Application example:

Color measurement of plastic pellets with the Agera – The release analysis

Reliable release analysis in the production of plastic granulate is important to ensure consistent color quality of the end product. It is helpful to define the correlation between the color of the granulate and the extruded color sample platelets as precisely as possible so that the number of extrusions required can be reduced. A spectrophotometer that can be used to measure both pellets and platelets is therefore useful. Of course, the measuring process should be as simple as possible and not hold up the workflow. The task Since pellets have a non-uniform surface, the largest possible surface area must be examined during the color measurement or a simple averaging of several measurements...

Color measurement of plastic pellets with the Aeros – routine analysis

Rapid routine analysis in the production of plastic granulate is important in order to detect whether the color of the product is correct at an early stage in the process. Particularly in the case of translucent granules, close attention is paid to the degree of yellowness (Yellowness Index YI). This allows you to intervene in the process in good time to ensure the correct color of the end product. Due to the non-uniform surface of the pellets, it is important to measure as large a surface as possible. Of course, the measuring process should be as simple as possible and not hold up the production process. The task Since pellets have a non-uniform surface, the largest possible surface area...

Color measurement of contact lenses

Color measurement of contact lenses

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light transmission. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
