Low Labor Cost
Because today's metal stamping is automated, minimal intervention is required from the operator controlling the machine. All steps in the manufacturing process are performed by stamping machines, with minimal manual labor involved.

Production Process

Cutting

Cutting is the application of sufficient shear force to separate a material into parts. The shear force must exceed the ultimate yield strength of the material before the material will fail and separate at the cut location.

Punching

Punching, sometimes called punching, works in a similar way to blanking. This is the process of drilling small shapes, such as holes, into a workpiece by applying shear force. Cut a section of the blank off the blank and discard it after ejection. Punching can be combined with the blanking step in a single downward stroke of the punch.

Prune

Trimming is the step of reducing the width to the desired profile by cutting off the outer perimeter of the workpiece. Excess materials are often discarded or can be recycled.

Metal Stamping

Imprinting is a bending process that compresses the workpiece between a punch and die. The compression force is 30 times greater than other bending processes. The punch and die complement each other and their internal dimensions provide the precise angle or curvature of the workpiece. This method produces a more precise bend and eliminates the tendency to spring back.

Metal Flanging

When flanging or bending, the workpiece is clamped between the lower die and the upper pressure pad, and the protruding material is pushed down by the forming punch. Compensate for springback by modifying die and punch angles. This method is suitable for vertical bends.

Casting

Imprinting is a metal processing process that changes the surface roughness of a workpiece by applying compressive stress resulting in plastic deformation. This operation reduces the surface grain size of the workpiece and increases the hardness of the workpiece surface while maintaining its toughness and ductility.

Brushed Metal

Deep drawing is a metalworking process that forms blanks into hollow or concave shapes with seamless edges and parts in a variety of diameters. It is performed by clamping the blank into a die using a blank holder and forcing it through it using a draw punch. As the drawing punch punches downward toward the cavity, the workpiece undergoes a complex series of stresses and deformations to form the finished part.

Embossing

Embossing is the process of creating a raised surface on a workpiece, while debossing is the process of creating raised or depressed areas on the workpiece. These processes are accomplished by pressing the workpiece against a male and female mold. These processes are used to mark or decorate artifacts by adding unique and specific details such as text, logos, and images.
