Maruem Manufacturing contributes to cost reduction across various industries through precision cold forging.
Traditionally, for products that cannot be formed using special stepped parts, screws, or standard two-stage headers, we have relied on machining from bar stock or combining several parts. As a result, various issues have arisen, including high costs, quantitative supply shortages, and increased complexity in assembly. To address this problem, Maruemu Manufacturing Co., Ltd. utilizes multi-stage headers to cold forge complex shapes, contributing to cost reduction and stable supply.

basic information
**Features** ○ Cold forging processing can produce large quantities in a short time without generating chips at room temperature. Compared to machined or assembled parts, it is cheaper and allows for the consolidation of various components into a single part, enabling cost reductions such as savings in parts management. ○ Cold forging processing has minimal dimensional variation, allowing for the supply of high-quality and stable parts. Additionally, it exhibits superior strength compared to machined products due to continuous fibrous structures and work hardening (where metal fibers are not cut). ○ Environmentally, cold forging processing can produce clean products that are considerate of the environment by using cold forging materials that do not contain lead or selenium, which are found in cutting materials. ● For other functions and details, please contact us.

Company information
In 1927, our company started as a manufacturing and sales business focused on hardware products such as cotter pins, and in 1957, we began mass production as a pioneer of stainless steel screws. The frontier spirit that lives on at Maruemu Seisakusho has led to the creation of core technologies based on our history and the accumulation of skills, including "product development of new materials, material processing, and fastening technology."
