A stamping press machine is a type of metalworking equipment used to shape or cut metal sheets by applying pressure through a die. It operates by forcing a piece of metal into the desired shape or size using a combination of pressure and precision-made dies. Stamping press machines come in various types and configurations, including mechanical, hydraulic, and servo-driven presses, each offering unique advantages and capabilities. These machines are commonly used in industries such as automotive, aerospace, electronics, and appliance manufacturing for processes like blanking, forming, piercing, bending, and coining.
What Is Metal Stamping
Metal stamping is a manufacturing process that involves shaping flat sheet metal into a desired final shape using heavy-duty pressing machines equipped with upper and lower halves of a die set. These dies can perform a variety of operations such as shearing, bending, blanking, trimming, piercing, drawing, or stretching the starting material to achieve the correct dimensions for the final product.
The versatility of stamping allows for the creation of a wide range of products, from simple brackets to complex automotive vehicle frames.
This efficiency-focused strategy is fundamental to high-volume, cost-effective production across multiple industries. By streamlining manufacturing processes and reducing the need for additional equipment, labor, and time, metal stamping offers significant cost savings for large-scale production. Compared to machining, which involves material removal to create parts, stamping is generally more material-efficient and quicker for high-volume production runs.
Conversely, in comparison to forging, stamping can be more cost-effective for certain intricate and precise part geometries, offering advantages in terms of speed and consistency.
6 Types of Metal Stamping Process
Punching
This process involves using a punch and die to cut holes or create openings in the sheet metal. It is widely used for creating perforations, slots, and openings in various products, such as automotive parts and electronics applications. Punching can create holes with precise size tolerances, with accuracy depending on the material kind and thickness, the hole size, and the quality and wear condition of the tooling.
Blanking
Blanking is akin to punching but focuses on cutting out the desired shape from the sheet metal rather than creating holes within a desired final shape. Steel blanking is a cost-efficient process for tailoring metal parts to specific needs, with continuous material feed-reducing setup and part handling. It minimizes waste through efficient part nesting and cuts shipping costs by sending just the net weight. Initially catering to the automotive and fabricating sectors, its adaptability to various industries is expanding due to the blanks’ capacity to conform to the final part shape, making it increasingly attractive to a broader industrial spectrum.
Bending
Bending is the process of shaping sheet metal by applying force to deform it at specific angles. In press brake forming, a workpiece is placed over a die block, which molds the sheet into a shape by exerting both tensile and compressive stresses. Springback occurs post-bending, requiring over-bending to achieve the desired angle. Material type and forming method influence springback. Bending elongates sheet metal, measured as bend deduction from outer edges and bend radius on the inside, influenced by: die choice, material properties, and thickness. Additionally, items like tabs and channels are crafted through bending.
Coining
Coining is a metal-forming process that employs pressure to shape and harden the surface of a workpiece, creating precise forms and smoothing edges. This method reduces the need for secondary processes like deburring and grinding, saving time and costs. Coining finds applications in various industries, especially when intricate details and fine features are essential, such as in: coin production, badges, buttons, and precision components.
Embossing
Embossing involves creating raised or recessed designs on the surface of sheet metal. It is commonly used for decorative purposes on items like ornate panels. Precision in embossing ensures the desired aesthetic and tactile qualities.
Flanging
Flanging is the process of forming a raised edge or lip on a sheet metal component. It is employed in applications such as automotive panels and ductwork. The accuracy of flanging is to ensure proper sealing and structural integrity.
