Cornerstone of outstanding products
                  - Upon research and utilization in the field of product application

 

With the development of plastics industry and the expanding application of extruding machines,the requirements of screw element and kneading block is no longer limited to traditional styles. Thanks to our rich experience that we have accumulated in the field of screw elements manufacturing,we intend to provide our customers with the most appropriate solution based on the properties of their own products, for instance nitriding steel,chrome-vanadium steel .stainless steel and wear-resistant powder metallurgy (foreign steel) like SKD11,K110,1.2379,W6Mo5Cr4V2,SuS18,HS35,HS45,HS10V etc. The truth is  that appropriate accessories can  effectively  extend the uptime of  the  basic  machines and meanwhile reduce  the production  cost for customers.

 

Regarding  to  production specifications,apart from offering standard components manufactured by general domestic factories, we alse desgin and  manufacture special-purpose components according   to  your  requests.  At the  same time ,we also provide  surveying and  mapping business  as well  as processing business for  accessories made by major foreign extruding machine  companies.

 

 

Precise Element & Timely Delivery
                 -Our attiude to win the trust of customers

 

In today's booming market ,the accuracy of the product is no longer the gap between foreign manufactures and domestic ones. To ensure that all products will be precisely fitted,German and Japanese original CNC machines hava uesed in the manufacture of screw elements. While inproving the product precision,we alse pay great attention maturity of the heat treatment process. We engage to provide better service along with the upgrade of our technology.

 

What's more, our company is fully accredited with ISO14001 quality management standard. Highly motiveted  team  of  spare parts specialists is ready to do anything to remedy your problem . With abundant raw materials and sufficient inventory, we promise you for timely delivery.
