What is metal stamping?

What is metal stamping?
Metal stamping involves using a die to apply pressure to sheet metal, causing plastic deformation;

typical precision ranges from ±0.001 to ±0.004 inches.

Main types of stamping processes
Six key processes: perforating, blanking, deep drawing, coining, piercing, and embossing.

Types of stamping equipment
Crank presses, screw presses, and hydraulic stamping presses.

Stamping dies and tooling
The core component is the stamping die; associated tooling includes punches, bending dies, and various auxiliary tools.

Materials used in metal stamping
Common materials include carbon steel sheets, stainless steel sheets, aluminum-magnesium alloys,

and copper/zinc sheets; carbon steel is the most widely used, accounting for approximately 45% of the total.

Typical stamping manufacturing process
The process relies on presses and dies to apply external force to sheet metal,

causing plastic deformation or separation to achieve the desired workpiece shape.

Common Defects in Stamping
Defects generally fall into three categories: forming quality, dimensional accuracy,

and surface condition; the most typical issues are cracking, wrinkling, and burrs.

Industries Using Metal Stamping
Metal stamping has a wide range of applications, primarily in automotive manufacturing,

followed by electronics, home appliances, and aerospace; it is also extensively used in the medical, construction,

and consumer goods sectors.

How to Choose the Right Stamping Equipment
Clarify process and product requirements; calculate the necessary pressure (tonnage);

evaluate parameters and select the equipment type; and finally, consider the brand and after-sales support.

Quality control in metal stamping
Ensuring quality requires maintaining the die in good condition, using high-quality materials,

and establishing proper quality control procedures.

Consistent quality throughout the entire process-from first-article inspection during die debugging to mass production-along with appropriate inspection methods, is essential to guarantee the quality of stamped parts.
