Hello dear BESTECH, 

Good Morning. 

Here is Anna from Hengong Casting iron bar foundry, which is now a leading and professtional manufacturer.

The most notable characteristic of continuous iron bar is its fine-grained, dense, as-cast mircostructure. 

 therefore this material can be widely used in machinery industry and also a better choice for stator and piston in Vacuum pump. 

May i visit you this afternoon today by telephone? thanks a lot. 

Best Regars

Anna
