Below is a list of Cold Headed Parts manufacturers from Medina, Ohio. Cold headed parts are finished or stock shapes produced through a specialized process more broadly known as cold working. Although cold heading is a popular option, it is part of this larger group of manufacturing processes also referred to as cold forming. As the name would suggest, none of these techniques involve heat, but instead materials are processed and formed at ambient temperatures. While the name might imply that the temperature is further reduced for cold metallurgical processes, most are carried out with machines and materials left at room temperature.
