What is a Stamping Press and How Does it Work?

A stamping press is a sophisticated piece of machinery that uses mechanical or hydraulic force to shape metal. The press operates through a controlled stroke movement, applying precise pressure to form, cut, or shape metal workpieces. Modern presses can achieve hundreds of strokes per minute (SPM), making them essential for high-volume production.

Types of Stamping Presses: Mechanical vs. Hydraulic

Mechanical Presses

• Powered by flywheel energy
• Higher speeds (typically 20-1500 SPM)
• Better for high-volume production
• Fixed stroke length

Hydraulic Presses

• Fluid-powered operation
• Adjustable force and speed
• Ideal for deep drawing operations
• Variable stroke length
