Beijing Hengci Magnetic Technology Co.,Ltd.

Company Profile

  Beijing Hengci Technology Co.,Ltd is specialized in developing and manufacturing the 3rd generation rare-earth permanent magnet-Nd-Fe-B.Since its foundation in Beijing in 1989,our company has established our technology development and marketing center in Beijing and set up our own production factories in Shanxi province and Beijing city that now consists of 3 factories.Our production capacity reaches 600tons per year,and we are building a new modern plant whose production capacity will be 1000 tons per year.

     Through continuos investment and innovation, our company has developed quickly and kept in standing at the top rank in the industry in china. A Certificate of Technology Achievement for the high-grade Magnet were granted by State Foreign Economic and Trade Committee in 1998. In 2000, our company has been selected as the high-technological enterprise of   Nd permanent magnet supported by state and provincial government and a total amount of US$6millions were invested for our new plant that will go into operation in July 2001.

    Now various grades and shapes of  the magnet could be supplied. Our maximum magnetic property in mass production is 45M which is the highest in China. With excellent magnetic characteristics and low prices, Our product is under a wide application in many fields such as electro-acoustic device, electrical motor, instrument and meter, auto industry, petrochemical industry and magnetic health-care product.   

    With the powerful technical force, advanced manufacturing technology and scientific management, we have been offering our customers with high quality products, prompt delivery, reasonable prices and good service. It's always our hope to establish a friendly and mutual benefit business relationship with our customers and most importantly it is our commitment to give our customer the best quality with satisfied service.
