  • All the orders, records of production and inspection would be kept for 5 years
  • High Precision:

 

Honed tube (Roughness of tube is 0.2μm and straightness is less than 0.15/1000), piston rod (Plating thickness is 10-100 micron. Surface roughness is 0.2μm and straightness is also less than 0.15/1000)

 

Product details are completely according to International Standard, chrome rod and honed tube must be cut flatly, and no chrome marks on the surface of rod. (Most of domestic mills don’t do this in order to reduce cost)
