The Efficiency of Cold Formingand Micro-manufacturing

and the Modern World

What is Cold Forming?

*It is the process of forging metals at near room temperatures

*Metal is formed at high speed and pressure into tool steel or carbide dies

*This process increases the metal’s hardness, yield strength, and tensile strength

Material UsageBenefits

*Cold Forming production speeds are 500-600, compared to 1-2 parts per minute in screw machining.

*It results in low material loss of 0-3%, which is much less than 70% or more material lost in the machining, grinding, or

chipping processes.

*Due to its efficiency, cold forming results in viable cost effective and high quality parts

*Cold Forming is often the best alternative for metals that are more difficult to work with (i.e. nickel, gold, pure copper,

titanium, palladium)

*The increased metal strength can improve toughness and fatigue performance

Can You See the Difference?

*Other processes leave scraps which are usually discarded or recycled

*Note the absence of scraps in the cold forming process

What is Micro-manufacturing?*Micro-manufacturing is an innovative metal forming

technology

*It produces parts with little to no scrap and produces them up to 100 times faster than traditional processes i.e. screw

machining

*It is applicable to a variety of materials which include: stainless steel, precious metals,

nickel alloys, low-expansion alloys, or anycopper alloy

Its Impact on Industry*in 2012, manufacturers accounted for $1.87 trillion of the economy

*Micro-manufacturing has improved industries such as: medical devices, aerospace, automotive, and energy exploration and

development

*It has contributed safer, more efficient automobiles

*It has produced medical equipment including: as dental implants, endoscopic devices, drug delivery, interventional therapies and

implantable devices.

*It has produced energy efficient technologies such as solar panels, complex navigation systems for airplanes and space shuttles.
