The Benefits of Metal Stamping

Cost-Effective Production: Metal Stamping is a cost-effective manufacturing method, the high-speed operation of stamping presses and the ability to produce multiple parts in a single stroke significantly reduce labor costs and increase production efficiency.

Versatility in Material Selection: Metal Stamping can be performed on a wide range of materials. This versatility allows for the production of stamped components with different properties, strengths, and characteristics to suit specific application requirements.

Material Savings and Efficiency: Metal Stamping optimizes material utilization by nesting multiple parts within a single sheet or strip of material. This minimizes waste and maximizes material efficiency, resulting in cost savings and reduced environmental impact.

Strength and Durability: Stamped components often exhibit excellent strength and durability due to the cold-forming process. The plastic deformation and work-hardening of the metal during stamping increase its mechanical properties, resulting in robust and reliable parts.

Consistency and Repeatability: Once the stamping dies are set up, the process can consistently reproduce identical parts with high accuracy and minimal variation, ensuring quality and reliability in mass production.

High-speed presses: High-speed presses enable fast strokes for high-volume production.

Numerical Control System: CNC (Computer Numerical Control) systems are commonly used to control and program punch presses. They allow precise control of the machine’s movement, speed and power, ensuring accurate and repeatable punching operations.

Automatic Feeding Systems: Automatic feeding systems such as coil feeders and tape feeders are used to feed metal materials into stamping machines. These systems ensure consistent and precise material feeding, reducing set-up time and increasing productivity.

In-die sensors and monitoring systems: In-mold sensors and monitoring systems are used to monitor various parameters during the embossing process, such as e.g. B. force, position, temperature and lubrication. These systems provide real-time feedback to maintain quality and prevent problems.

Quick-Change Tooling System: The quick-change tooling system allows for quick tool setup and quick switching between different punching tasks. They enable efficient production with less downtime.

CNC Turning

To increase cycle times on grinding operations, software is available that measures the pressure and noise generated during the CNC grinding process. When, because of the material characteristics or cut, this software recognises that resistance on the cutting tool has diminished it accelerates the grinding wheel accordingly. Conversely, should noise and pressure indicate that resistance has risen, it slows the tool.

Related CNC Milling 2
CNC Milling

CNC milling is just one of the CNC machining processes available. Milling is a particular form of precision CNC machining. Milling uses a cutter that removes material by moving into the work-piece at an angle. The movement of the cutter is controlled by computer instructions, allowing for extreme precision and repeatability.

What is Metal Stamping?

Metal stamping, also known as sheet metal stamping, is a process that involves the use of a stamping press and specialized dies (tooling) to shape sheet metal into a specific design or form. The die, which is the key component in this process, employs various techniques to manipulate the metal until it achieves the desired shape or form.

The term ‘die’ refers to the tooling utilized to produce the final shape of the workpiece. This manufacturing technique is highly efficient for medium to high volume production of metal parts, making it a cost-effective option for various production requirements.

Evolution of Metal Stamping

The history of metal stamping traces its roots back to when stamping irons or hammers were used to form shapes on coins. This technique saw significant advancement with the development of the screw press in the 14th century. In modern times, metal stamping has evolved to incorporate contemporary equipment and processes, enhancing its efficiency and precision.

Techniques in Metal Stamping

Metal stamping is a cost-effective, high-speed, and precise manufacturing process that employs a variety of techniques, including:

  • Blanking

Blanking removes a piece from the primary material to form the desired shape. In this process, the extracted piece itself becomes the final product or ‘blank’, as opposed to being discarded.

  • Punching

Punching involves using a die and punch to cut shapes out of sheet metal. The punch pushes through the material and into the die, removing sections of metal to form the desired shape in the remaining workpiece.

  • Coining

Coining compresses material between a die and a press or punch with extreme force. This process is used to create fine features and tight tolerances on part surfaces.

  • Bending

Bending shapes sheet metal into bent forms, typically in L, U, or V-shapes. This process involves bending the material beyond its yield point around a single axis.

  • Flanging

In flanging, a die and a flanging tool section work together to produce flanges or flares on a workpiece. The flange part of the tooling shapes the material into the desired form.

  • Drawing/Forming

Drawing and forming use compressive force to mold sheet metal into a cavity or to shape it by wrapping the metal over a die’s shape.

  • Embossing

Embossing employs a shaped die and a press to imprint a pattern or design onto the material, creating a raised or recessed relief.

  • Curling

Curling is used to round off sharp edges or to form hollow rings in a design-specific manner. It also enhances the moment of inertia at the curled part of the workpiece.

  • Piercing

Piercing involves creating holes or closed shapes in a workpiece. The removed section is usually discarded, leaving the pierced pattern as the final part.

These techniques can be used individually or in combination, depending on the complexity of the parts required for a project. For instance, a simple bent design might only need bending, while more complex parts may require a combination of techniques like flanging and piercing. The specific needs of a project dictate which metal stamping techniques are most appropriate.
