Masterbatch

Color Formulation and Quality Control of Pellets/Resin

Masterbatch, a concentrated mixture of pigments or additives in a polymer resin, plays a pivotal role in achieving the desired color in plastics manufacturing. Color measurement instruments are integral to masterbatch production, allowing for precise color measurement that helps facilitate accurate color formulation and color quality control of pellets or resin. Konica Minolta offers a comprehensive range of color measurement solutions widely utilized in the plastic industry. Two notable options are the Spectrophotometer CM-5 and Spectrophotometer CM-36dGV, which provide accurate color representation across major colorimetric systems and indices such as CIE L*a*b* and Yellowness index (YI). These versatile instruments are capable of both reflectance and transmittance color measurements, making them ideal for evaluating the color of masterbatches, including resin, pigments, and additives. To ensure consistent and controlled sample preparation, a variety of accessories are available for these instruments, catering to different sample forms ranging from powder and pellet to liquid.

Molded Plastics

Color Quality Control and Verification

Precise color measurement is a fundamental quality control step of molded plastic production. Whether it’s manufacturing preforms or producing plaques and final plastic products, color measurement instruments such as spectrophotometers are utilized to evaluate color accuracy and consistency. Konica Minolta has a range of highly accurate spectrophotometers like the CM-5, CM-36dG, CM-26dG, and CM-700d models. These color measurement instruments enable objective and accurate color measurements of molded plastics, including plastic bottles, sheets, films, and other injection-molded and extrusion-molded parts, ensuring they meet their intended color specifications. With the SCI (specular component included) and SCE (specular component excluded) features, these color measurement instruments can accurately evaluate the color of opaque molded plastics with different levels of gloss and specular reflection. The Spectrophotometer CM-5 and Spectrophotometer CM-36dG also provide transmittance color measurement, enabling accurate and reliable color evaluation of translucent and transparent plastics.

Evaluate Gloss and Surface Finish Quality

Plastics often incorporate various texture effects, such as glossy or matte finishes, which serve both functional and aesthetic purposes. Konica Minolta, partnering with Rhopoint Instruments, has a range of instruments that can evaluate the gloss and other appearance attributes of plastics. One such instrument is the Rhopoint iQ-S, which allows simultaneous gloss measurement at 20°, 60°, and 85° angles, providing a comprehensive evaluation of a wide spectrum of finishes, ranging from matte to high gloss. The Rhopoint IQ Flex 20-S and Novo-Gloss Flex 60, equipped with a remote measuring head, are highly effective options when it comes to precise gloss measurement on small and curved plastic surfaces. Notably, both the Rhopoint iQ-S and Rhopoint IQ Flex 20-S also have the ability to evaluate various appearance attributes, such as reflection haze and DOI (Distinctness of Image).
