Japanese companies Toyoda Gosei and Kansai Paint have unveiled a groundbreaking in-mold coating technology that dramatically cuts carbon emissions during the manufacturing of large automotive plastic parts. The innovation integrates the coating process directly into molding, eliminating the need for traditional post-painting furnaces that are both energy-intensive and costly.
Reducing CO₂ Emissions by 60%
According to Toyoda Gosei, the new in-mold coating system reduces CO₂ emissions by about 60% compared to conventional painting methods. By removing the need for separate drying furnaces used to cure paint coatings, manufacturers can save substantial energy while maintaining production efficiency.
Streamlined Production with Premium Finish
The process not only enhances sustainability but also improves manufacturing efficiency by shortening production time and minimizing workflow steps. Despite the reduced energy use, the technology meets stringent automotive standards for appearance, adhesion, and durability, ensuring that vehicle parts retain a high-quality aesthetic finish.
Advanced Materials and Coating Expertise
Kansai Paint played a key role by contributing its formulation expertise and advanced coating materials. These ensure that the coating adheres perfectly under molding conditions, providing a smooth and durable surface without compromising on texture or color consistency.
Driving Japan’s Green Manufacturing Vision
The collaboration between Toyoda Gosei and Kansai Paint aligns with Japan’s national decarbonization and sustainable manufacturing goals. As global automakers seek to reduce emissions across the supply chain, innovations like in-mold coating represent practical steps toward achieving low-carbon production.
Commercialization and Future Applications
Toyoda Gosei plans to apply this technology to future large automotive components, including bumpers and exterior panels. The companies aim to expand commercialization in the coming years, offering automakers a cost-effective and eco-friendly alternative to traditional painting lines.
A Step Forward in Automotive Sustainability
By merging advanced material science with green engineering, Toyoda Gosei and Kansai Paint are setting a new benchmark for sustainable automotive production. Their innovation not only contributes to carbon reduction but also demonstrates how technology can deliver both environmental and design excellence in next-generation mobility manufacturing.
