A stamping press is a machine tool that can precisely shape or cut metal to your specifications. The stamping process includes forming, drawing, trimming, and punching the metal with a die. Typically, this process can be applied to both metal sheets and coils. The press consists of a support plate and a slider. The stamping process involves the formation of metal between the two press halves.

The upper component is attached to the rams of the press, while the lower component is attached to the stationary plate (or bed) of the support. Some large stamping presses also have a die cushion integrated into the support plate, which can assist in applying the force of the empty holder.
 

Applications

Stamping presses are an excellent marking tool for repetitive dimpling marking applications. They are machines that require little maintenance and are relatively easy to operate. In fact, manual impact presses are easy to operate. One of the most critical benefits of the press is that it incorporates the versatility and customization of steel punches, types, dies, and counting heads for devices that are suitable for low to high-volume applications. The stamps, type, and dies can be personalized with logos or custom fonts and are made of hardened, high-quality steel tools for long life and longevity.

The production of dies for stamping presses concerns mainly sheets. With the mold, it can do punching, punching, forming, deep stamping, dressing, precision punching, shaping, riveting and stamping, etc. They are widely used in electronics, communications, computers, household appliances, furniture, transportation, and produce cars, motorcycles, and bicycles.
 

Press Types

Stamping also known as pressing involves placing a flat sheet, in the form of a coil or a blank, in the press. In the press, the tool and the die surface form the metal into the desired shape. Punching, bending, stamping, and flanging are the stamping techniques used to shape metal. Before the material forming via the press, you need specialists that can design the tooling using professional engineering technology. These designs need to be as precise as possible to ensure that each punch and bend maintains proper clearance and therefore optimal part quality. But what types of stamping presses are there?
 

Mechanical vs. Hydraulic

There are mechanical and hydraulic drive presses. Mechanical presses usually use an excentric motor, while hydraulic presses use hydraulic cylinders to move the ram up and down. Mechanical presses are powered by a flywheel-driven motor. The handwheel stores kinetic energy to turn the handwheel down to the ground. These types of stamping presses can operate at a steady pace and can quickly manufacture metal goods in assembly environments. Mechanical presses can also produce higher cycles per unit of time and are widely found in industrial presses.

In the case of a hydraulic type, there is a steady pressing force during the stroke and, in the case of a mechanical press, there is a continuous pressing force. A die guides the pressing operation, and the hydraulic press uses air or liquid to exert pressure. Stamps are commonly used in a wide range of industries, including aircraft, transportation, medical, and manufacturing. Stamping is suitable for high-volume, high-precision jobs.
 

Single-acting vs. Double-acting

Single-acting stamping presses have one ram, whereas double-acting presses have a divided ram. The piston is clamped to the end of the die. It creates up and down movement as the metal is fed through the die of the press. The metal was first unwound from the coil and pushed into the straightener. After the metal has been sliced, it can be freely formed. Shearing happens in the case of puncture when piercing the metal.
 

Advantages

Compared with traditional processing, using the stamping press saves energy and materials, and the processing efficiency is higher. The punching machine is composed of the support plate and slider segment, large pad metal block, and the pressing mold is fixed on the metal block. The upper mold and the lower mold are placed between the upper mold and the lower mold, deformed by the punching pressure and further processed into the desired product, and the reaction force produced by the punching is pressed by the punch itself completely absorbed, so the quality of the bed is also an important indicator to ensure the stability of the press.
