What is Fourslide Stamping?

Fourslide stamping,also referred to as multislide stamping, is a metalworking technique for producing elaborate and complex metal pieces. It is a type of progressive die stamping in which parts are produced from flat strip or wire stock using a fourslide machine, sometimes known as a multislide machine. The machine moves the material through a succession of dies using four or more slides to generate the desired form.

This technology has various advantages over typical pressing processes, including enhanced variety, greater design flexibility, faster production, and cheaper production costs. Given these benefits, fourslide stamping has become a popular production technique for high-precision applications in a variety of industries, including automotive, aerospace, medical, and electronics.

Advantages of Fourslide Stamping

1.Fourslide stamping machines are capable of performing multiple forming and stamping tasks in a single operation, making them a start-to-finish solution for creating complex parts. Unlike other stamping methods, such as progressive die stamping, fourslide stamping does not require additional secondary operations, reducing overall production time and costs.

2.Fourslide stamping offers versatility in metalworking as it can manipulate the workpiece from multiple directions to produce complex parts with intricate details, twists, and curves. Additionally, this process can be used with various materials such as copper, steel, aluminum, bronze, brass, and more, making it suitable for a wide range of applications.

3.Design flexibility is another advantage of fourslide stamping. Traditional press operations often require expensive and time-consuming modifications to the die or the manufacture of an entirely new die to accommodate design changes. However, fourslide stamping machines can perform multiple motions and accommodate design modifications with simple adjustments to individual sliding tools. This allows for greater flexibility in product design and a faster turnaround time for design changes.

4.Fourslide stamping can save costs by reducing the need for additional secondary operations, such as bending, forming, or drilling, which may be required with other metalworking processes. The process also produces minimal scrap or waste, which can further reduce material costs. Overall, the cost efficiency of fourslide stamping makes it an ideal option for producing high-quality parts at a low cost.

5.Speed is another key advantage of fourslide stamping, as it operates at high speeds and can perform multiple operations in one pass. This not only helps to reduce costs but also enables a much faster turnaround time for production.

Additional process employed in Fourslide Stamping

Fourslide stamping involves a variety of processes beyond the basic technique of drawing sheet metal into a 3D shape. These processes can be used to further customize and refine the final part.

  • Adding beads, ribs, and flanges to the part’s surface. These raised features can enhance the strength, stability, and rigidity of the part.
  • Bulging:stretches and expands metal in specific areas to create a desired shape or feature.
  • Coining:compresses the metal in a particular area to create a raised or recessed feature, often for decorative or functional purposes.
  • Curling:bending the edges of the metal sheet to form a rounded or curved shape.
  • Dimpling creates a small indentation or depression in the metal sheet, usually for aesthetic or functional purposes.
  • Embossing:raises or recesses a design or pattern in the metal sheet.
  • Extruding is another process that forces the metal through a shaped die to create a continuous profile or shape.
  • Hole forming is used to punch or drill holes into the metal sheet for attachment or assembly purposes.
  • Ironing is a process that compresses the metal sheet to create a smoother and more uniform surface finish.
  • Marking can stamp or laser etch identifying information onto the part, such as part numbers or logos.
  • Necking :narrows the diameter of the metal sheet in a specific area to create a desired shape or feature.
  • Notching :involves cutting small grooves or notches into the metal sheet, often for assembly or attachment purposes.
  • Threading creates threads on the part either by cutting them directly into the metal or by adding a threaded insert.
  • Trimming involves cutting excess material from the edges of the part to achieve the desired final shape and dimensions.

How does Fourslide Stamping Work?

Fourslide stamping machines are used to mould and shape metal wire or strip into complex pieces using a mixture of sliding tools, punches, and dies. The machine receives the wire or strip and feeds it through a sequence of stations where various tools and dies carry out particular shaping and cutting processes. These stations could involve threading, cutting, bending, and straightening.

The metal strip or wire is pressed under pressure by the sliding tools at each station before being molded or cut into the required shape. The workpiece gradually assumes its final shape as it passes through the various stations.

Different tooling and dies can be added to the machines itself to personalize them, allowing for variety and flexibility in the kinds of parts that can be produced. Aside from making design modifications very simple, this customization also eliminates the need for pricey new dies or tooling.

Fourslide Stamping Design Guidelines

The reasonable design of the fourslide stamping directly determines the price, quality, and capacity of the product.

 The material type should be carefully chosen depending on the intended use and the part’s needs.We suggest to choose the ductile and easily formed materials, such as steel, aluminum, stainless steel .

Thinner materials are easier to shape, but they may lack the necessary strength. Then the material thickness should be chosen to guarantee that the finished product is strong and durable.


The N and R values are essential characteristics that assist determine the material’s formability. More formability is indicated by higher N and R values.

 To ensure that the final product has the proper dimensions and shape, the blank size and shape should be carefully created.

Part geometry should be tailored to reduce stress concentrations and ensure that the component can be manufactured without tearing or wrinkling.

To guarantee that the part is produced correctly and to reduce the danger of flaws, the press speed should be carefully managed.

 Carefully plan the draw radii to guarantee that the part can be created without tearing or wrinkling.

The draw ratio is the proportion of the blank diameter to the final part diameter. A larger draw ratio necessitates more force and may lead to material thinning.

To reduce the chance of faults in the final item, the die surface finish should be smooth and devoid of imperfections.

 The die temperature should be carefully managed to ensure proper material formation and to reduce the danger of flaws.

 To reduce friction and ensure that the part can be produced without tearing or wrinkling, a suitable lubricant should be used.

 The draw bead height and shape should be carefully planned to guarantee that the part can be produced correctly and that faults are minimized.

Binder pressure should be carefully managed to ensure proper part formation and to reduce the chance of faults.

 The binder deflection should be carefully designed to ensure proper component formation and to reduce the risk of faults.

The standoff height should be carefully selected to enable proper part formation and to reduce the chance of faults.

Fourslide Stamping FAQ

Below you will find the answers to the most common questions we get about the metal stamping process. 

Fourslide stamping is a metalworking process that involves bending and shaping flat metal strips or wire into complex shapes and forms using a four-slide machine. The four-slide machine has four slides or moving components that work together to form the metal into the desired shape. The slides can move in multiple directions, allowing for intricate bends and curves to be created in the metal.

The disadvantages of fourslide stamping include limited part complexity and difficulty in maintaining tight tolerances. Fourslide stamping may not be suitable for producing complex or intricate parts, and may require additional finishing operations to achieve the desired level of precision. Additionally,the production rate for fourslide stamping is generally slower than those other methods.

Fourslide stamping and traditional stamping differ in their equipment and production processes. Fourslide stamping uses a specialized machine with four slides that move horizontally and vertically to shape the metal into the desired form. This allows for more complex shapes to be produced in a single step, and also enables tighter tolerances and finer details.

Traditional stamping, on the other hand, uses a hydraulic or mechanical press to apply force to a sheet of metal, which is then cut and formed into the desired shape using a single die. While traditional stamping can also produce complex shapes, it typically requires multiple steps and dies, resulting in a longer production time and potentially higher tooling costs.

Overall, fourslide stamping is a more efficient and precise method for producing complex metal parts, while traditional stamping is better suited for simpler shapes and larger production runs.

As a general rule of thumb, any material less than 2-in. wide, less than 0.075-in. thick, and within 15-in. in blank length, can use the fourslide process.

Fourslide stamping is a versatile process that can be used to create a wide range of small to medium-sized metal parts, such as clips, brackets, springs, electrical contacts, and various other components used in the automotive, aerospace, electronics, and medical industries.
