1.Do you have these Difficulties?
 
Difficulties a material that is difficult to shape or form
not to invest capital to replace worn out machines, retool machines or add capacity
using equipment infrequently and can't justify the expense
benefit from the reduced machining associated with near net shapes
buying from machine shops and find the cost expensive
lack the skilled labor to produce precision, high-quality parts or who can't find skilled craftsmen

If yes,please use Precision Cold Drawn Products
2.Feature and Customer Benefits
 
Cold drawn products Features Customer Benefits
Improved Size and Section Tighter size & section tolerances Reduces machining losses
Dimensional consistency within each bar
Dimensional consistency from bar to bar
Better surface finish  Ground and polished Reduces surface machining &
improves quality
Surface Improvement (Shaving or turning to produce "Defect Free" surface)
Tighter straightness tolerances  Improved Straightness Facilitates automatic bar feeding
Increased Mechanical Properties Yield strength Can reduce the need for hardening
Tensile strength
Hardness
Improve Machinability and Productivity Increased machining rates Enables higher machining feeds & speeds and
improved machined finish
Longer tool life
Improved yield
Improved Formability Improves response to spheroidization Cold Drawn and Annealed
Improved Cost Effectiveness Optimizes machinability and reduces yield losses
