PEACE-LON VIETNAM COMPANY LIMITED
Peace-Lon is a brand of Heiwa Sangyo Co., Ltd., a Japanese company that has manufactured self-lubricating oil-impregnated plain bearings and sintered mechanical parts utilizing powder metallurgy and sintering technology since its establishment in 1961. Peace-Lon specializes primarily in small self-lubricating oil-impregnated plain bearings with diameters ranging from approximately 0.5 to 22 mm, which are used in motors, automobiles, home appliances, office automation equipment, and various precision mechanisms for shaft support and maintaining stable operation. With over 60 types of raw materials, we can develop materials and propose combinations tailored to the specific requirements of each application, such as low noise, high load capacity, wear resistance, oil leakage prevention, and high-temperature environment compatibility. By consistently performing all processes from raw material selection and mixing, mold design, compaction, sintering, sizing, and oil impregnation to final inspection, we propose optimal bearing specifications according to load, speed, PV value, operating temperature, and required lifespan. Furthermore, Peace-Lon is expanding its overseas production and sales system. In Vietnam, its fifth factory has been established at Lot C8b-2, Ngang 4 Street, Phu An Thanh Industrial Park, Ben Luc, Tay Ninh Province, Vietnam, strengthening the supply system for self-lubricating oil-impregnated plain bearings and sintered parts for customers in the Southeast Asian region.

About Casting
Powder metallurgy is a processing technology that manufactures parts by forming metal powder and sintering it at temperatures below its melting point. Because it does not involve a melting process, it enables the compounding of high melting point metals and dissimilar metals that are difficult to mix by melting. It also offers excellent material yield and is characterized by the ability to reduce post-processing through near-net-shape forming. Representative processing methods include press forming using molds and metal injection molding (MIM) for complex shapes. It is utilized for manufacturing high-precision and high-performance parts in a wide range of fields, including automotive parts (gears, bearings), electrical and electronic components (magnetic materials), porous filters, cemented carbide tools, and aerospace parts. The high degree of design freedom, leveraging the characteristics of the materials, is also a major advantage.
