ABOUT Cold Forming
Technology: Cold Forming Services are metals forming services similar to cold heading in which pressure is used to cold flow metals into various shapes. It is used to make automotive parts such transmission gears, pinion shafts, etc. A number of different services are associated with cold forming, including coining, thread rolling, ironing, swaging, etc.Material is not removed during the process, producing little scrap compared with conventional machiningCan be a high production rate processCold forming imparts strength to parts through grain redistributionCold forming can increase the strength of weaker material through cold working, often matching the characteristics of superior metals that must be hot formedGood interior and exterior surfaces can be produced
Cold forming is an alternative to forging and machining processes.
Advantages: Cold forming services are capable of producing near net shape parts in a variety of metals.
Limitations of Cold Forming ServicesNot suited to low volume runsThere are limits on diameter to length ratiosGalling of surfaces can occur without appropriate lubrication
Applications: Cold forming services are used to make many parts in the automotive and aerospace sectors.Spline shaftsTransmission gearsMedical devices
