Toyota is also providing its patents and expertise to vacuum press manufacturer Mikado Technos, which has incorporated its own technologies to develop and manufacture a stamping-type plating machine for sale through Kanematsu.
As the world swelters and arctic fires burn uncontrolled, Toyota Motor Corporation is reducing CO2. Toyota is using the world’s first stamping-type plating technology that has a polymer membrane (solid electrolyte membrane), through which metal ions can pass, to apply plating only to areas requiring it. The technology is used in the plating process for forming copper, nickel, and other metal coatings on substrates during the manufacturing of electronic parts.
This new stamping-type plating machine eliminates the need of a dipping process where parts to be plated are completely immersed in multiple baths of plating solution, which is required in the most common plating processes at present. As a result, waste solution can be dramatically reduced to about one-thirtieth and CO2 emissions to about one-third, which contributes to a significant reduction in environmental impact. The technology also reduces plating time and the process footprint.
Toyota has also announced a collaboration with Mikado Technos Co., Ltd. and Kanematsu Corporation to manufacture, sell and expand the use of new plating machines based on this technology.
During the next two to three years, Toyota hopes to sell the stamping-type plating machine to several companies as a test machine for verification and evaluation. Then, from 2023 or 2024, with the aim of achieving widespread use, it will expand sales more broadly for general users as a full production machine.
Toyota decided to launch the stamping-type plating machine, which is expected to deliver these outcomes, and expand use to many companies in a range of industries not just to its business partners in the production of Toyota automobiles, to help reduce the impact on the environment and provide other benefits.
The newly developed stamping-type plating machine has a head, with the upper part filled with solution, and a solid electrolyte membrane, through which metal ions pass, mounted to the tip of the head that is pressed against the area to be plated. Hence the stamping name. This structure enables the solid electrolyte membrane, which is mounted to the tip of the head, to be pressed against only that part of the substrate that requires plating. When the electric current flows, the metal plating is applied, like a stamping but only to the area in contact with the membrane.
In the conventional plating process, however, substrates are completely immersed in solutions of copper, nickel or other plating metal and the metal film (plating) is created when the electric current flows. Multiple large baths for dipping the complete substrates are required for this and substrate washing processes before and after plating. Large amounts of plating solution must also be used because the complete substrates must be immersed in the baths, which means that large amounts of plating solution must also be discarded (wasted) after use. The entire plating process, including the equipment for removing toxic substances released into the air and for treating large amounts of waste solution, can be extensive.
Toyota announced the Plant Zero CO2 Emissions Challenge as part of the Toyota Environmental Challenge 2050, an initiative to contribute to the creation of a sustainable society, which is part of a set of 17 goals for achieving a sustainable society. The Toyota Group will work together to fulfill this challenge, adopting stamped plating machines within the Group and steadily reducing the amount of CO2 it emits during its production processes.
