Molded Plastic Parts

HunterLab has instrument and sample handling devices to meet almost any customer needs. One such need that we are able to meet is the measurement of molded plastic parts, such as the one pictured above. These plastic parts are actually covers for a stud finder tool. The nature of these parts presents a few difficulties for color measurement.

One of the biggest challenges is that the parts have a curvature to them that make measurements on our bench top instrument difficult. These parts also have a slight shine and texture that needs to be taken into account when measuring. To include the shine component of the plastic part it needs to be measured with a sphere instrument. The measurement on a sphere instrument ensures that the sample is measured in Reflectance Specular Included mode which will measure the appearance of the part.

To accurately measure the sample with the curvature it has, a small area of view should be used. The small area of measurement provides the flattest area possible on the plastic part for the measurement. Since the plastic is slightly non-uniform and a curved area is being measured it is best to average multiple readings to achieve a repeatable measurement method.

The MiniScan EZ sphere instrument with small area view is the best instrument for the measurements on the plastic part. The sphere allows for consideration of the shine and the small area of view helps to measure as flat of an area as possible. Averaging multiple readings on the MiniScan EZ with small area of view provides a very repeatable measurement method for plastic parts such as this.

Optimizing Measurement Consistency

Often times it can be helpful to change the standardization interval on instruments to correspond with shift changes or other events that might be more convenient. When the instrument reaches the end of this standardization interval it will prompt the user to re-standardize the instrument before moving forward with measurements.

To change this setting on the MSEZ instrument navigate to Global Options from the main instrument menu. In the middle of the screen you should see STDZ Interval (h) with a value to the right of it. Scroll down to this option so that it is highlighted and then use the right and left arrows on the key pad to change this interval. The default for this option is usually 8 hours, and is what most users find to be appropriate.

Geformte Kunststoffteile

HunterLab verfügt über Instrumente und Probenhandhabungsgeräte, die nahezu alle Kundenanforderungen erfüllen. Ein solcher Bedarf, den wir erfüllen können, ist die Messung von geformten Kunststoffteilen, wie das oben abgebildete Teil. Diese Kunststoffteile sind eigentlich Abdeckungen für ein Bolzenfinderwerkzeug. Die Beschaffenheit dieser Teile bringt einige Schwierigkeiten bei der Farbmessung mit sich.

Eine der größten Herausforderungen besteht darin, dass die Teile gekrümmt sind, was die Messungen mit unserem Tischgerät erschwert. Diese Teile haben auch einen leichten Glanz und eine leichte Textur, die bei der Messung berücksichtigt werden müssen. Um die Glanzkomponente des Kunststoffteils zu berücksichtigen, muss es mit einem Kugelinstrument gemessen werden. Die Messung mit einem Kugelmessgerät stellt sicher, dass die Probe im Reflexions-Spiegelungs-Modus gemessen wird, der das Aussehen des Teils misst.

Um die Probe mit ihrer Krümmung genau zu messen, sollte ein kleiner Messbereich verwendet werden. Der kleine Messbereich bietet einen möglichst flachen Bereich auf dem Kunststoffteil für die Messung. Da der Kunststoff leicht ungleichmäßig ist und ein gekrümmter Bereich gemessen wird, ist es am besten, mehrere Messwerte zu mitteln, um eine wiederholbare Messmethode zu erhalten.

Das MiniScan EZ Kugelinstrument mit kleinem Sichtfeld ist das beste Instrument für die Messungen am Kunststoffteil. Die Kugel ermöglicht die Berücksichtigung des Glanzes und der kleine Sichtbereich hilft dabei, einen möglichst flachen Bereich zu messen. Die Mittelwertbildung mehrerer Messwerte mit dem MiniScan EZ mit kleinem Sichtbereich bietet eine sehr wiederholbare Messmethode für Kunststoffteile wie dieses.

Piezas de plástico moldeado

HunterLab dispone de instrumentos y dispositivos de manipulación de muestras para satisfacer casi todas las necesidades de los clientes. Una de estas necesidades que podemos satisfacer es la medición de piezas de plástico moldeadas, como la que aparece en la imagen superior. Estas piezas de plástico son en realidad cubiertas para una herramienta de localización de espárragos. La naturaleza de estas piezas presenta algunas dificultades para la medición del color.

Uno de los mayores retos es que las piezas tienen una curvatura que dificulta las mediciones en nuestro instrumento de sobremesa. Estas piezas también tienen un ligero brillo y textura que hay que tener en cuenta a la hora de medir. Para incluir el componente de brillo de la pieza de plástico, es necesario medirla con un instrumento de esfera. La medición con un instrumento de esfera garantiza que la muestra se mida en el modo de reflectancia especular incluida, que medirá el aspecto de la pieza.

Para medir con precisión la muestra con la curvatura que presenta, debe utilizarse un área de visión pequeña. La pequeña área de medición proporciona el área más plana posible en la pieza de plástico para la medición. Dado que el plástico es ligeramente no uniforme y se está midiendo un área curvada, lo mejor es promediar varias lecturas para lograr un método de medición repetible.

El instrumento de esfera MiniScan EZ con vista de área pequeña es el mejor instrumento para las mediciones en la pieza de plástico. La esfera permite tener en cuenta el brillo y la pequeña área de visión ayuda a medir un área lo más plana posible. El promedio de varias lecturas en el MiniScan EZ con vista de área pequeña proporciona un método de medición muy repetible para piezas de plástico como ésta.

成形プラスチック部品

HunterLabでは、ほぼすべてのお客様のニーズにお応えできる装置とサンプルハンドリング装置をご用意しています。そのようなニーズの一つに、上の写真のような成形プラスチック部品の測定があります。これらのプラスチック部品は、実際にはスタッドファインダー工具のカバーです。このような部品の性質上、色測定にはいくつかの困難が伴います。

最大の課題のひとつは、部品に湾曲があり、卓上測定器での測定が難しいことです。また、これらの部品にはわずかな輝きと質感があり、測定時に考慮する必要があります。プラスチック部品の光沢成分を含めるには、球体測定器で測定する必要があります。球体測定器で測定することにより、サンプルは部品の外観を測定するReflectance Specular Includedモードで測定されます。

試料が持つ曲率を正確に測定するためには、小さな測定範囲を使用する必要があります。小さな測定領域は、測定に使用するプラスチック部品上で可能な限り平坦な領域を提供します。プラスチックはわずかに不均一であり、曲がった部分が測定されるため、再現性のある測定方法を達成するには、複数の読み取り値を平均化するのが最善です。

小面積測定が可能なミニスキャンEZ球面測定器は、プラスチック部品の測定に最適な測定器です。球体は光沢を考慮することができ、小面積の視野は可能な限り平坦な領域の測定に役立ちます。MiniScan EZで複数の読み取り値を平均化することで、このようなプラスチック部品の再現性の高い測定が可能になります。
