The design of the coating die can be done using Excel spreadsheets.
Dyes are used to apply liquid materials to tapes and wire materials. The coating thickness is one of the important management items. We can provide a calculation method for designing the main parameters of the dye. Additionally, for those who want to acquire the technology for flow analysis for dye design in-house, we can also explain the theory of flow analysis and provide technical materials. This service is not suitable for those who want to use expensive package software for rigorous calculations. However, we believe it is a suitable service for those who want to design dyes based on fluid theory in order to respond quickly to customer demands.

basic information
The fluid analysis I am considering here is as follows: 1) It targets Newtonian fluids. While it is possible to address non-Newtonian fluids, it is limited to those for which viscosity can be modeled. 2) The Navier-Stokes equations will be approximated for analysis. The effects of viscous and pressure terms will be taken into account. (This is an analysis based on lubrication theory.) 3) It will be provided as an Excel spreadsheet. By inputting values into the spreadsheet, flow rate and coating thickness can be calculated. It can also calculate the tension of the fluid acting on the workpiece and the pressure generated within the die. As a technical advisor, I believe that die design can be one of the means to solve the challenges you are currently facing. Entering into a technical advisory contract will be a condition for this provision.

Applications/Examples of results
This analysis method was utilized in the design of the coating die for optical fibers. At that time, the coating was being done at over 1000m/min. Currently, it is being coated at even higher speeds. The material used is UV-curable resin, but this analysis method can also be applied to other resins. For example, it can be applied to the design of extrusion dies (the die section of a crosshead). Additionally, this analysis was applied to the design of dies for coating tape substrates. The flow of the coating fluid when the substrate is moving is governed by the flow field caused by the movement of the substrate and the flow field generated by the pressure due to the wedge shape. The analysis we provide calculates that flow field. I think it might be difficult to understand with just a verbal explanation, so please feel free to contact me.

Company information
The D&T Lab focuses on supporting research, development, design, and prototyping for manufacturing process engineering (design) and production technology development (technology). Particularly in the case of new businesses, it is necessary to introduce technologies that the company does not possess and to select and collaborate with partner companies. By utilizing so-called open innovation, we aim to shorten the marketing and product/service development periods, facilitate early entry into new fields and applications, and establish a unique strategy for the company using that information and technology to promote the business in earnest. Once we reach that stage, operations can be managed similarly to existing businesses. Therefore, the challenges of new ventures depend on how efficiently and effectively we design the entry stage. At that stage, it is necessary to gather information and technologies that the company does not possess and to make choices that are suitable for the company. I have experience in the development and launch of mass production equipment and the introduction of new products into factories. From the successes and failures I encountered, I have learned how to design mass production lines and introduce new products in my own way. Additionally, I possess processing techniques for various materials such as copper products, compound semiconductors, quartz glass, and plastics. I will contribute using the insights gained from these mass production technologies and material processing techniques.
