Colour measurement of granules and pellets, coloured 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, colourless and possibly translucent sample that is tested before mixing with colour additives. The coloured 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

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

    This geometry according to DIN corresponds very precisely to the colour 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 colour 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.

  • Easy to use and precise

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

Aeros

Laboratory device for measuring colour and degree of browning

  • Non-contact measurement

    The sensor detects the sample without contact and without having to measure through plastic or glass.

  • Large surface area

    The rotating sample plate captures 177.25 cm2 of the sample in 35 measurements in 5 seconds.

  • Integrated QC software

    The EasyMatch QC Essentials quality control software is integrated into the device and provides all the necessary 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.
  • Easy to use and precise

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

Application example:

Colour measurement of granules with the Aeros spectrophotometer

Color measurement of granules and pellets with the Aeros spectrophotometer from HunterLabDetect color changes at an early stage, ensure quality and increase productivity In the production of various granulates, the product is analyzed with a spectrophotometer during the manufacturing process to ensure the correct shade. A change in the color of the end product should be detected at an early stage in the process in order to be able to intervene in time and "save" the product. Production should not be disrupted or held up by this quality control. Special measuring techniques help to carry out reliable checks during production with simple handling. With the HunterLab Aeros you can precisely...

Colour 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...

Measuring the color of nuts

For snack food, it is important to ensure that the instrument has a large observation area, as this allows the sample to be easily placed under the sensor in different sized sample plates or in a Petri dish.
