Precision Metal Stampings
Typically light gauge metal parts, precision metal stampings can be formed at minimum thicknesses of around .002" to .005". Able to be formed from a wide range of materials, precision metal stampings can be stainless steel, platinum, beryllium copper, phosphor bronze, nickel silver, aluminum and many others. Best in small to medium production runs, precision metal stampings should be utilized in all industries in which exact part measurements are crucial to the success of their applications.
Precision metal stampings are formed in the same manner as normal metal stampings, mainly differing in terms differ in terms of measurements and accuracy. To begin, mechanical and hydraulic presses can both be used to form precision metal stampings. However, hydraulic presses are more commonly used because they have a variety of types of frames, including C-frames, straight sides, H-frames and four-column, as well as the ability to deliver full power at any point in the stroke, making the ideal for precision metal stampings. When the press is in operation, the ram, also referred to as a slide, maintains movement to and from the motionless press bed. The die, which is a press tool with a uniquely designed cavity, shapes metal parts from inserted sheet metals. The upper component of the die is connected to the press slide, and the lower component is connected to the press bed. A die component called the punch is used to create the shape by pushing the metal sheet through the die. After the precision metal stampings are formed, they are typically subjected to varied secondary processes, depending on the requirements of the application. Some common secondary processes used on precision metal stampings include electropolishing, deburring, heat treating, plating and passivation.
