Rainbow Ming was established in Miaoli, Taiwan, in January 1975. We are one of the leading manufacturers of powder metallurgy parts. We started our business producing oil-impregnated bearings in the early years. Later, we further expanded the business in the production of sewing machine parts. We had received several positive reviews from our customers and partners and earned recognition in the powder metallurgy industry during this period. As the industry progressed and technology evolved, we committed to the development of metal powder materials and production techniques to meet the various demand of different industries. Today, Rainbow Ming’s powder metal parts and components of stainless steel are widely used on the market of home appliances, automobiles, motorbikes, lock systems, medical equipment, power tools, industrial machines, robots, ships and vessels, road alignment equipment, optical equipment, and many more. We are not satisfied with what we have achieved in Taiwan over the decades. Rather, we want to set our foot on the markets in Asia, Europe, and America. We will continue to dedicate ourselves to extensive research and development in powder metallurgy so as to present the best quality products and services to our customers.
