ZHOUSHAN DINGHAI HONGFANG SCREW MANUFACTURING CO.LTD

Since our founding in Zhoushan city in 1999, we are one of the earliest manufacturers producing twin screw barrel in China. Now we have developed our product line to conical and parallel twinscrew barrel, single screw barrel for both extruders and injection molding machines, twin screw main extruders and even whole PVC compounding and granulating line.

During our early operation period, we dedicated ourselves to serve small scale companies who are producing various PVC products. We were helping them to improve product quality by altering screw structure according to their material ingredients and production situation. These experiences help us to accumulate technology know how and understanding customer needs much better.

Now we have developed into a modern company expanding market abroad. We offer various solutions against wear and corrosion to customers and provide training and installing services. If you have problems in choosing screw barrel or main extruder, please talk to us!
