Precision plastic molding of thermosetting resin for optical device modules.
BMC molding solution that achieves both optical precision and high rigidity.
To achieve high measurement accuracy and performance maintenance in camera modules and various optical units, it is essential to select materials that are resistant to surrounding thermal changes and are less prone to aging, along with advanced processing technologies. In particular, for internal structures where slight misalignment of the optical axis affects performance, it is required to achieve a high level of both excellent rigidity and low thermal expansion (low CTE). Our BMC molding processing technology provides high-precision module components that meet these stringent optical requirements. 【Main Application Scenes】 - Structural components requiring precise optical axis retention: lens barrel holding frames, sensor module housings, precision bases for actuators - Optical components exposed to high temperature and thermal environments: module components for automotive cameras, peripheral mechanisms for high-output projectors 【Benefits of Implementation】 - Weight reduction and cost savings through metal alternatives - Stabilization of optical axis and dimensional accuracy under thermal cycling environments - Increased design flexibility in complex optical module designs *Product materials summarizing the corresponding technologies and precision molding equipment of Murakoshi Seisakusho can be checked via the catalog download button.
