What is stamping press machine?

A stamping press machine is employed in the manufacturing sector to shape and cut metal into desired forms. The machine is commonly used in the stamping process, utilizes dies and punches to cut and shape metal with precision. Stamping press machines can be either mechanical or hydraulic, offering the ability to produce diverse products with high accuracy and speed. The machine operates by exerting force on the metal, typically using a ram or plunger. This force transforms the metal into the desired shape, determined by the specific dies and punches employed. Stamping press machines find application in various industries such as automotive, aerospace, appliance, and electronics, where they contribute to the production of items like automotive body parts, electrical contacts, and electronic components.

Types of Presses

Two common types of presses include mechanical presses and hydraulic presses. Typically, presses are connected to an automatic feeder that feeds sheet metal into a medium in the form of coils or blanks.

Mechanical

Mechanical presses use an electric motor connected to a flywheel to transmit and store energy. Depending on the particular press, their punch sizes range from 5 mm to 500 mm. The speed of mechanical presses also varies, usually between 20 and 1,500 strokes per minute, but they tend to be faster than hydraulic presses. These presses range in size from 20 to 6,000 tons. They are well suited for making shallower, simpler parts from sheet metal coils. They are often used for progressive and transfer stamping for high-volume production.

Hydraulic

Hydraulic presses use pressurized hydraulic fluid to apply force to the material. A hydraulic piston discharges the fluid at a force level proportional to the diameter of the piston head, allowing for advanced control over the amount of pressure and more consistent pressure than mechanical presses. Additionally, they have adjustable stroke and speed features that typically provide full power at any point in the stroke. These presses are typically sized from 20 tons to 10,000 tons and have stroke sizes from approximately 10 mm to 800 mm. Hydraulic presses are typically used in smaller production runs to make more complex and deeper stampings than mechanical presses. They offer greater flexibility due to adjustable stroke lengths and controlled pressures.
