"We want to achieve better design at a lower cost." Achilles Teflon responds to such requests from designers and engineers. By adopting RIM molding, it realizes numerous advantages such as "larger molded products" and "freedom of design" without being constrained by the limitations of conventional injection molding or vacuum/pressure molding. Additionally, unlike standard injection molding, Achilles Teflon offers three types to choose from based on application, expanding new possibilities for product design. *For more details, please refer to the catalog.

In the automotive industry, reducing vehicle weight is a crucial challenge for improving fuel efficiency and reducing CO2 emissions. To achieve weight reduction, it is essential to change the materials of components and reconsider their structures. Achilles Teflon's RIM molding allows for more flexible designs compared to traditional injection molding, enabling shape designs that contribute to weight reduction. This allows for greater design freedom, balancing lightweight construction with aesthetic appeal. 【Application Scenarios】 - Automotive parts (interior, exterior) - Parts that require weight reduction - When wanting to enhance design flexibility 【Effects of Implementation】 - Improved fuel efficiency due to weight reduction - Increased design flexibility - Potential cost savings

In the medical device industry, there is a demand for miniaturization, lightweight design, and high precision of products. Particularly for medical devices that support patient safety and accurate diagnosis and treatment, the precision of component shapes and durability are crucial. Traditional molding methods have limitations in design flexibility and cost, but our large RIM molded products address these challenges. 【Application Scenarios】 - Precision medical device components - Complex-shaped medical device housings - Medical devices requiring durability 【Benefits of Implementation】 - Improved design flexibility - Cost reduction - Realization of high-quality products

In the construction machinery industry, there is a demand for large components that balance product durability and design. Particularly for parts used in harsh environments, high impact resistance and weather resistance are crucial. Traditional molding methods may impose constraints on design flexibility and cost. Achilles Teflon RIM molding addresses these challenges. 【Application Scenarios】 - Large exterior parts for construction machinery - Interior parts - Various covers 【Benefits of Implementation】 - Improved design flexibility - Cost reduction - Achievement of high durability

In the interior design of railway vehicles, a balance between aesthetics and functionality is required. In particular, safety and durability are crucial, and high quality is demanded for interior components. Additionally, cost is an important factor, and efficient manufacturing methods are sought. Achilles Teflon, through RIM molding, achieves "large-scale molded products" and "freedom of design" without being constrained by the limitations of traditional injection molding or vacuum and pressure molding. This expands the possibilities for interior design in railway vehicles and enables the realization of high-quality interior components at a lower cost. 【Application Scenes】 - Interior components such as seats, walls, and ceilings of railway vehicles - Interior components with high design quality - Large and complex-shaped interior components 【Effects of Implementation】 - Increased design freedom - Cost reduction - Realization of high-quality interior components
