From 2017, we established an intelligent workshop with all automatic machined. There are five lines only for producing exported products. The new workshop is executing 6S strictly. The production capacity will be 1500 tons per month.

Jiangsu New Heyi Machinery Co., Ltd is specialized in producing precision long small diameter axes and  hydraulic piston rod. The products are widely used in mine machinery industry, textile and printing machinery industry and so on. Hydraulic cylinder piston rods are also supplied as the OEM parts for  many large and medium enterprises, such as Heli Forklift Ltd, Hangzhou Forklift Ltd, Sanyi Heavy Industry Ltd.  We have enjoyed a good reputation with high quality and good after-sale service in recent years.  Also our products are exported to USA, Canada, Southeast Asia, Austria, Australia and Brazil etc.

We have set up the principle of “high quality, good reputation”, carried out a series of rigorous quality 

management system, and have already passed the ISO9001:2008 international quality system. Our inspection 

apparatus and production equipment are advanced and superior, that ensure the product of high quality.

We have complete piston rod manufactured equipment covering all processes. The critical processes of heat 

treatment and chrome plating are finished in our own company, which ensure the quality control of the key 

technical requirements.

Our factory is located in Wuxi which is famous for the peaches. The transportation is very convenient, only 

30 minutes to Wuxi Airport and railway station. About 1 kilometer from the entrance of the expressway access 

to Shanghai. The factory covers an area of about 25000 square meters and has more than 200 employees,
