jiangyin dongjie Textile Machinery Special Parts Co. Ltd. is a well-known company involved in specialized production of such textile machinery special parts and accessories as rollers， rings， tape drive pulleys and ring bars. The company passed the ISO9001-2000 quality system certification in 2002.

Founded in June of 1997， the company has gathered and developed a large number of intermediate and senior engineering and technical personnel with a wealth of practical experience and the ability to develop textile machinery parts after nearly a decade of rapid development. Dongjie is equipped with more than advanced manufacturing equipment of 500 sets， fixed assets of over 60 million yuan， employees of more than 500， and professional and technical personnel of over 50. In terms of the annual production capacity of the company currently， there are 25，000 sets of tape drive pulleys， 15，000 unites of ring bars， five million rollers and three million high-precision rings.

With the professional products， Dongjie cooperates with the well-known textile machinery and textile enterprises at home abroad such as Jingwei Textile Machinery Co.， Ltd. and Marzoli （Dongtai） Textile Machinery Co.， Ltd， to provide its special parts for them.

As one of the excellent textile machinery special parts manufacturers in China， it is the second time for Jiangyin Dongjie to participate the Indotext exhibition， with its newest and hottest products， such as roller and high precision ring.

Its roller products including： roller for spun yarn machine of cotton textile， roller for roving machine of cotton textile， roller for spun yarn machine of woolen textile， roller for roving machine of woolen textile， ramie roller， flax machine roller， jute machine roller， roller for textile machine for silk， and machine roller， bars and roll machine roller， comber roller， roller for twisting frame， fancy twisting machine roller and non-standard roller. And the new generation of super high precision none mechanical wave tight roller is equipped the characteristics： bending resistance improves more than 9.1% comparing with common roller； the random two rollers hatched grafting static pulsation 100% is within 0.05mm， it does not need gasket when installing the upper machine； directly operate to connect and screw down， without checking， dynamic pulsation 98% is within 0.02mm， it does not exceed 0.03mm in maximum； roller none mechanical wave rate reaches over 98%， mechanical wave inspection over 98% is flat wave amplitude， it does not exceed 3mm in maximum； all common variety staple silver reaches 2007 USTER@ Statistics 5% level； it does not move for long term usage and the operation is steady with good consistency.

The high precision ring also serves as an outstanding product of Dongjie. Adopting the special type bearing steel material to beat into the blank， it makes the internal grain structure become very meticulous， compact and symmetrical； the heat-treatability become very steady and the deformation become extremely small. Forming directly by the import special equipment ensures the high precision and the good consistency of making ring， it supports the guarantee to shorten the distance of ingots.

Moreover， the surface becomes smooth and subtle after the nanometer-technology processing. And with roughness of surface is Ra

The technology on surface guarantee the ciliiform of the cladding and thickness is above 8 μm. The cladding attaches firmly and will not fall after long using. The hardness of the surface can not less than 1050HV0.2 good staving quality and steady useful time is above 5 times than normal chrome ring. Therefore， it is extremely fit for the demand of compact-spun high count cotton yarn and high-count yarn and the first choice to be a substitute for the imported ring.
