Metal stamping is a manufacturing process used to transform metal sheets ( often called “ blanks ”) into different shapes . It uses cold forming techniques , which means that no heat is used to reshape the metal . Instead , the metal is placed between dies and stamping presses that shape and shear it by applying pressure . A high-speed process , metal stamping is one of the fastest and most cost-effective solutions for manufacturers in need of high-quality components ( especially for large-quantity orders ).
Stamping presses utilise the force of a moving ram to transmit force , or an amount of tonnage , to specific tooling to achieve a product ’ s final shape , often with little or no scrap and , whenever possible , with minimal operator intervention . Stamping dies are the tools that shape and cut sheet-metal parts .
There are four main types of metal stamping processes : progressive die stamping , transfer die stamping , four-slide stamping and fine blanking . Within each of these stamping processes , various stamping techniques are employed . These can include punching or perforating ( to remove scrap pieces from the metal sheet as a punch enters the die ); blanking ; bending ; coining ( leaving an impression in a metal workpiece ’ s surface ); flanging ( using a flange or flare tool to create a joint in the metal sheet which connects multiple components ) and embossing . Hot stamping entails heating the material until it becomes malleable . It is subsequently subjected to a formation and rapid cooling process to produce a transformed and hardened material .
Some of the most common types of metal stamping machines include mechanical , hydraulic and servo presses that are fitted with multiple dies to cut and shape the sheets of stainless steel and metals such as aluminium , zinc and copper . Better control , greater speed and versatility , shorter cycle times and higher energy savings are just some of the hallmarks of the latest technologies .

AIDA will debut its NSX mechanical stamping press at FABTECH 2023 in Chicago , USA , this September . This newly designed ; two-point ; 110-metric-ton unitised frame press is capable of speeds ranging from 120-300 strokes per minute . It features a zero clearance ; lubrication-free ; eight-point roller slide guide system and dual counter-rotating eccentric shafts . Press and die integrity are protected by AIDA ’ s metal seal type Hydraulic Overload Protection ( HOLP ) at 10 milliseconds to zero pressure .
AIDA is a global specialist in the design ; manufacture ; sale ; service and support ; refurbishment and modernisation of metal stamping presses and metalforming automation equipment . AIDA servo and mechanical stamping presses range in capacity from 35 to 4,000 tons ; from a few to 800 strokes per minute ; from gap frame to straightside ; high-speed to cold forging , transfer and progressive die ; material handling and coil-feeding equipment .
Two product lines that are dedicated to the production of motor laminations are the AIDA HMX Series and AIDA MSP Series presses . The AIDA MSP press enables users to produce motors such as EV motors , HEV motors and energy-efficient home appliance motors .
