Nanjing Light Industrial Machinery Works is a company with 30years history directly controlled by the center.In 1999 has promoted to a national grade one large scale enterprise ranking the 234th position among 500 biggest enterprises of Chinese machinery industry.We own a central air-conditioned machining center and imported processing workshop with more than 60 precise process equipments.Our measurement center is national grade II.To keep a distance with the domestic rivals in technology and reduce the gap with foreign competitors at the same time,to ensure that enterprises in the technology advantage in market competition,we continue to absorb the foreign advanced technology to the retrofit design of the welded pipe units.The new product more than 40%among we produced very year.

On the other hand,the company devoted greater effort in reformation of technical equipment,speed up the upgrading on large equipment.Now,we have 15m planer,6m open side planer,4m gantry milling,boring machine and other processing

equipment,based on the configuration of the digital display precision boring machine,5 vertical lathe,diameter of 1.2m,length of 5m,underwater plasma cutting machine,CNC cutting,sandblasting and other large processing equipment.At the same time with purchasing large processing equipment,we bought 10 sets processing center from USA,Italy and other companies,ensured the processing accuracy and efficiency of the key parts of main product include large,special large parts.

Nanjing Zhongqing Machine Making Co.,Ltd is the largest subsidiary of Nanjing Light Group,mainly engaged in manufacturing various series ERW straight seam pipe welding lines,high precision cold roll forming lines,and high speed coil sheet slitting&cut-to-length lines,the technology of the product is in the leading status in the domestic.These lines are capable of producing pipe diameters fromφ8 toφ711(25IN)and the thickness of wall can from 2.3 to 25mm.Adopt advanced flexible forming process,and finite element simulation analysis technique to produce high precision steel pipe meeting API 5L and API 5CT standards with X60-X80 materials.And also specialized in manufacturing precision cold roll forming line,which can produce all kinds of complicated section of roll forming products,widely used for automobile bumper,door sill,steel door frame curtain wall,c-type,U-type,hat-type,stand column,beam and complicated section open or closed rolled product.

We have obtained ISO9001 certificates in 1998,selling well in all cities and provinces around China,our products are also exported to clients in such countries and regions as Indonesia,Vietnam,Qatar,Peru,Kazakhstan,Chile,and Salvador.We will continue to intensify the development of new products,focus on customer request,and meet the requirement of the customers.
