Large RIM molded products [Achieving better design at a lower cost]

More freedom and affordability in large plastic molding.

"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. For inquiries, please contact Koyama Co., Ltd.*
