Precision Gear Manufacturing with Consistent Quality
Gears and pulleys are critical mechanical components that require precise material selection, dimensional accuracy, and tooth profile accuracy. If any of these requirements are not met, the component cannot perform its intended function. At Minami Design, we manufacture high-precision gears and pulleys with stable and reliable quality, utilizing the advanced machining skills of our experienced engineers. In prototype development, gears and pulleys are often designed with unique shapes and custom dimensions that cannot be accommodated by standard off-the-shelf products. By combining NC lathe machining with secondary processes such as machining center operations, we are able to handle complex geometries and high-precision requirements through integrated, multi-process manufacturing. We accept orders starting from a single unit, making our services ideal for prototyping and small-lot production. From functional prototypes to pre-production verification parts, we propose the most suitable manufacturing methods based on your application and requirements. Please feel free to contact us for any inquiries regarding gear and pulley manufacturing.
