When you need metal to be shaped, stamped or cut

Stamping Stamping metal pressings are made by mechanical or hydraulic presses. Mechanical presses are common since they can reach higher cycles over specific periods. Mechanical presses for stampings can deliver full force only at the bottom of the stroke. On the other hand, hydraulic presses delver full force wherever desired. Fine blanking The process of fine blanking is limited in terms of material to brass, stainless steel, aluminum, copper, alloy, and carbon. Although similar in many ways, fineblank stampings differ from other metal pressings. A fine blanking press will include precision components such as a hardened die punch, hardened blanking die, and a guide plate. Stamping vs. fine blanking Both methods of metal pressings are capable of producing the same outcome. However, it is important to consider the material being used, the number of metal pressings needed, and how they need to be made. Fine blanking is a specialized form of blanking that eliminates any fracture zone during shearing since the whole part is compressed while the upper and lower punch extract the fineblanked parts. This process also eliminates the need for secondary operations such as profiles, holes, edges, and semi-pierces. Benefits of fine blanking Fine blanking saves time and money by eliminating the needs for lengthy processes and constant handling of parts. The entire process is automated with the potential to produce accurate edges at the rate of around 100 fineblanked parts per minute. It eliminates costly processes such as forging, manual machining and broaching. With Fine blanking technology, precision components can be produced from a wide range of materials with up to 10mm thickness. In conventional blanking there is considerable distortion on the component and material which can prove costly. On the other hand, there is no distortion during or after the fine blanking process. Fine blanking allows for maximum dimensional control and accuracy. Part flatness is easily maintained while it also produces superior finished edges when compared with other metal stamping processes. The automated process also allows for multiple features to be added simultaneously in a single operation. It is one of the most economical processes for the production of fineblanked parts in large quantities. Slots and holes can be placed accurately very close to the edges of the material or near to each other. Compared with conventional stamping, fine blanking has the ability to produce very small parts especially over 0.250' (6.35mm) thick.
