What is press working?

Pressing is a manufacturing method in which a die is pressed against a sheet of metal to form it. It is used in various fields such as automobiles, electronics, furniture, and home appliances because of its ability to flexibly process metals.

In this article, we will review the basics of stamping and explain the different types of processing and dies.

Basic Knowledge of Stamping Processes

What is press working?A processing method in which a metal plate or other material is sandwiched between dies and formed into a desired shape by applying pressure.It is. Stamping is used to manufacture a wide variety of products, including automotive parts, home appliances, and construction materials. Familiar examples include smartphone housings and automobile body panels, which are manufactured by press working.

Pressing is a processing method that utilizes plastic deformation of metal materials. Plastic deformation is the property of a material that does not return to its original shape when a force is applied to deform it, even if the force is removed. In press forming, this plastic deformation is used to deform the material to match the shape of the die.

The greatest feature of press work is the ability to produce large quantities of products in a short period of time. Once a die is made, products of the same shape can be manufactured efficiently. This is a very big advantage in today's manufacturing industry, where mass production is required.

Pressing is also suitable for manufacturing parts that require dimensional accuracy because of its high degree of precision.

Types of press work

There are various types of press work. This section describes in detail the characteristics and applications of each of the typical types of press work.

▼Types of press work

• shear processing
• Bending Process
• Drawing process

shear processing

Shearing process is,Processing method in which materials are clamped in a die and cut by shear forceIt is It is used not only for cutting materials, but also for drilling and cutting.

Shearing is a relatively simple process that can be used to produce products in a variety of shapes. For example, it is used to cut out a specific shape from a plate or to make a hole.

Shearing can also be combined with other stamping processes to produce products with more complex shapes.

Bending Process

Bending process is,Processing method in which materials are clamped in a die and bent by bending forceIt is It can bend materials at right angles or in arcs.

Bending can be used to manufacture products in a variety of shapes, such as box-shaped or L-shaped components. For example, it is used to manufacture metal boxes, housings, brackets, etc. In bending, it is important to accurately control the bending angle and radius.

Please refer to the following article for more information on bending in sheet metal processing.

Drawing process

The drawing process is,Processing method in which material is sandwiched between dies to form unevenness by squeezing forceIt is. Drawing can be used to produce three-dimensional shaped products such as cups and containers.

For example, it is used to manufacture beverage cans, pots, and automobile fuel tanks. In the drawing process, dies must be designed to take into account the elongation and contraction of the material.

Difference between press working and sheet metal working

Sheet metal fabrication and press work are bothProcessing method using plastic deformationand there is almost no basic difference.

The difference is that sheet metal processing is often performed using general-purpose dies, whereas press work uses specialized dies that are tailored to the shape of the product.

Types of dies used in press work

Various types of dies are used in press work. This section describes in detail the characteristics and uses of each of the typical types of dies.

▼Types of dies used in press work

• one-shot (e.g. story)
• transfer type
• sequential transmission type

one-shot (e.g. story)

Single-shot type is,Molds that perform one process in one press operationIt is It is used to manufacture products with simple shapes. Because of its simple structure, production costs are relatively low and maintenance is easy.

However, since only one process can be performed in a single press operation, multiple single dies must be combined when manufacturing products with complex shapes, which may reduce production efficiency.

transfer type

The transfer type is, Press dies for continuous processing by arranging single dies in process orderIt is It is used to manufacture products with complex shapes.

Equipped with a mechanism to move the material inside the die, multiple pressing processes can be performed automatically. This allows for high productivity and reduced labor costs.

sequential transmission type

Progressive type is,Molds capable of performing multiple processes in succession while feeding materialIt is Suitable for mass production, it can efficiently manufacture products with complex shapes and can automatically perform multiple pressing processes while continuously feeding material. This allows for extremely high productivity.

It also has high processing accuracy and can manufacture high-quality products. However, it has the disadvantages of a complex structure and high production costs.

Examples of stamping products

Press work is used for a wide variety of products around us. The following table summarizes examples of typical press work products.

field	Product Examples
Automotive	Body panels, doors, hood, fenders, bumpers, frames, seat frames, fuel tanks, etc.
Consumer Electronics	Enclosures of refrigerators, washing machines, air conditioners, etc., turntables of microwave ovens, inner pots of rice cookers, etc.
Electronics	Smartphone and PC casings, hard disk drive components, connectors, semiconductor components, etc.
Architecture	Roofing materials, wall materials, sashes, shutters, ducts, etc.
Daily necessities	Cans of juice or canned food, pots, pans, spoons, forks, etc.

Summary

In this article, we reviewed the basics of press work and explained the types of processing and dies.

Pressing is a processing method in which a metal sheet or other material is sandwiched between dies and formed into the desired shape by applying pressure. It can produce a large volume of products in a short time, and once the die is manufactured, products of the same shape can be produced efficiently.
