Tosaf Color Service – Brilliant metallic effects for stunning finishes
With over 50 years of experience, Tosaf Color Service is one of the pioneers in the coloring of plastics and is today a globally recognized specialist in additive and effect masterbatches. Using high-quality pigments, Color Service creates the conditions for cost-effective, environmentally friendly manufacturing of products with brilliant metallic surfaces—as high-quality alternatives to painting and electroplating metal in countless application areas, ranging from automotive parts to consumer goods, furniture, and toys.
With Sax, an experienced compounder, Color Service has been breaking new ground since 2025. Together with Grässlin, an experienced sales partner, the two companies have developed unique plastic compounds that are in no way inferior to high-quality metallic masterbatch solutions in terms of customer-specific color requirements and functional challenges—without compromising on color—for injection molding applications across numerous industries.
The compounds are manufactured using a wide variety of plastics according to customer specifications—typically PC/ABS, PA/ABS, PMMA, PET, PE/PP, and PC for the automotive industry. In principle, however, any polymer is possible, and as a general rule, the more transparent the polymer, the greater the depth, effect, and brilliance of the colors.
A perfect metallic look, even with 3D geometries
Tosaf Color Service’s advanced pigment technology and specialized manufacturing process effectively minimize segregation effects, which frequently occur in critical areas such as weld lines, cross-sectional transitions, or complex three-dimensional geometries with concave or convex contours. This optimization significantly reduces streaking and color variations—a decisive advantage for automotive suppliers as well as other industries with the highest quality requirements and rapidly changing, custom designs.
A sustainable alternative to painted metal
Products manufactured using this technology are characterized by exceptional color depth and excellent surface gloss. When used with eroded tools, they also enable precise, intricate texturing. These properties make the molded parts an environmentally friendly alternative to painted or electroplated components, as they eliminate the need for additional processing steps. This not only saves costs but also reduces the environmental footprint.
Another advantage: These single-material plastic parts are ideal for recycling and thus contribute to a sustainable value chain.
