Hello, everyone! Welcome to Thesun Industry, we are committed to bringing you the latest and most advanced metal stamping technology. If you’re looking to take your crafting game to the next level, you’ve come to the right place. We’re here to show you how metal stamping can transform your production process and take your products to new heights. So, buckle up and get ready to dive into the world of metal stamping with us!
Now, let’s get down to business.Metal stamping transforms flat metal sheets into precise shapes through various techniques such as blanking, punching, bending, and piercing. This intricate process is vital for producing components across automotive, aerospace, medical, and other industries.
Numerous companies in China specialize in metal stamping, catering to the growing global demand for rapidly produced, complex parts in large quantities.
Stamping, or pressing, involves placing flat sheet metal (either in coil or blank form) into a stamping press where a tool and die shape the metal into the desired form. Techniques such as punching, blanking, bending, coining, embossing, and flanging are commonly employed to achieve various shapes.
The process begins with designing precise tooling using CAD/CAM engineering technology. Accurate designs ensure each punch and bend maintains proper clearance, crucial for optimal part quality. Given the complexity, a single 3D tool model can contain hundreds of parts, making the design phase intricate and time-intensive.
Types of Metal Stamping Techniques:
Progressive Die Stamping
Progressive die stamping utilizes a series of stations, each performing a distinct operation. The process begins with a metal strip fed through a press, where it unrolls from a coil into the die. Each station incrementally shapes the metal through various cuts, punches, and bends, culminating in a finished part. This technique is ideal for complex geometries due to its:
– Faster turnaround times
– Lower labor costs
– Shorter run lengths
– High repeatability
Fourslide Stamping
Fourslide, or multi-slide stamping, involves four horizontal slides that simultaneously shape the workpiece. This method allows for intricate cuts and complex bends, offering:
– Versatility for more complex parts
– Flexibility for design changes
Material is fed into the fourslide machine and bent by tools on each slide in quick succession, making it suitable for highly detailed components.
Deep Draw Stamping
Deep draw stamping involves pulling a sheet metal blank into a die with a punch, forming it into a desired shape. It’s termed “deep drawing” when the depth of the drawn part exceeds its diameter. This technique is cost-effective for parts requiring multiple diameters and is commonly used for:
– Automotive components
– Aircraft parts
– Electronic relays
– Utensils and cookware
Short Run Stamping
Short run stamping is ideal for prototypes or small projects due to minimal upfront tooling costs. After creating a blank, manufacturers use custom tooling and die inserts to bend, punch, or drill the part. While per-piece costs might be higher, the lack of tooling expenses makes it cost-efficient for projects needing rapid turnaround.
Metal Stamping Design Processes
Metal stamping involves several intricate metal forming techniques, such as blanking, punching, bending, and piercing.
Blanking:
This initial process cuts the rough shape or outline of the product, aiming to minimize burrs that can increase costs and extend lead times. Key considerations include determining hole diameter, geometry/taper, and spacing between edges and holes, along with the first piercing placement.
Bending:
Designing bends in your stamped metal part requires ensuring sufficient material is available for the bend. Important factors include:
– Avoiding deformations by ensuring bends are not too close to holes.
– Designing notches, tabs, and slots with widths at least 1.5 times the material thickness to prevent punch breakage.
– Incorporating corner radii at least half the material thickness.
– Minimizing burrs by avoiding sharp corners and complex cutouts when possible and noting burr direction in the design.
Coining:
Coining flattens or breaks burrs by striking the edges of a stamped metal part, resulting in a smoother edge and added localized strength. This process can reduce the need for secondary deburring and grinding operations.
Upon finalizing the tool design, manufacturers utilize machining, grinding, wire EDM, and other techniques to produce the tool, readying it for the stamping process.
