Fundamental Technology

• Pigment dispersion technology

  Many pigments are used as colorants, and when it comes to such use, the important thing is to uniformly disperse and stabilize the pigments in the base material in order to maintain the intended color in inks and resin molding materials. Therefore, technology is required to control the properties of the material by controlling miniaturization, particle size, wettability, and other such aspects, and to commercialize the material without pigment aggregation.

• Material design and compounding technology

  In order to increase product value, a wide range of suitable functional materials must be selected according to the environment and application of the final product, and a combination of processes and formulas must be used to maintain its stable performance, with an example being color mixing technology.

• Kneading technology

  Mixing and kneading technologies are important when it comes to ensuring pigment dispersion and material compounding technologies are effective. These technologies are indispensable for product design, as extensional flow and shear flow in action in the process of kneading require optimization of kneading equipment according to the material while appropriately controlling the operating conditions.

• Forming technology

  It is said that the quality of the mold determines the quality of the product. To design the product, we start with analyzing the shape and function required of the molded product, and then design the mold before fabricating it under optimal mold processing conditions. We have accumulated an abundance of design and molding technologies by undertaking molding in optimal molding conditions, evaluating the resulting molded products, and then feeding the results of evaluation back into product design.

• Analytical and evaluation technology

  Alongside production technology, technology to correctly evaluate the performance of products used in various fields is the foundation of manufacturing. We provide reliable products thanks to an evaluation technology based on a wide variety of analysis devices and analysis know-how.

Analytical Equipment

In the process of developing various products, the ability to accurately evaluate the performance requirements of customers and to feed them back to the design of formulations is essential when it comes to rapid product design.
In addition to providing reliable products designed by leveraging our deep analytical know-how, the Tokyo Ink Group proactively works to solve customers’ problems even after products have been delivered by analyzing issues that may subsequently arise.
In addition, we have registered Tokyo Printing Ink as a Working Environment Measurement Agency that can perform the working environment measurement by our own experts (Saitama, No. 11-45). This is to conduct measurement work related to organic solvents, mineral dust, specified chemical substances, and metals in compliance with laws and regulations (analysis in compliance with WEEE and RoHS regulations for products, etc.).
