What is copper Stamping?

Copper stamping is a popular process for implementing multiple machining processes to reshape it and convert it into parts.

Have you got it?

In simple words, precision stamping machines  press the copper workpiece. And transform it into the desired shape. It is that simple.

Copper stamping process

The malleable and ductile properties of copper make it an IDEAL PIECE for pressing and stamping.

Progressive Stamping

In progressive stamping, a series of pressing, bending, and cutting occurs progressively. It has multiple tools arranged sequentially and performs bending, lancing, and punching.

Here is how progressive stamping occurs.

• Copper is placed on a conveyer that moves the location of the copper sheet after each operation.
• A simultaneous downward stroke of the press allows the belt to move the sheet to the next station.
• At each station, transforming jobs occur.

What can you do with it?

You can make copper brackets, frames, and caliper plates with progressive stamping.

Transfer Die Stamping

In transfer die stamping, the purpose is the same as progressive stamping, but the technique is different.

Instead of the conveyor belt, you get multiple stations with different jobs. If one station cuts the sheet, another transforms it into the required form.

At each station, you get altered pressure enabling a different job.

What can you do with transfer die stamping?

You can make frames, tubes, or copper shells.

Fourslide Stamping

Fourslide is a super fast and efficient method for copper stamping. We also call it a Multi-stamping process due to multiple rams arranged horizontally.

The horizontal arrangement of rams keeps multiple processes like pressing, cutting, and transforming being done simultaneously. It cuts the time-consuming processes discussed above. Even the efficiency of the process is quite impressive.

What can you do with it?

It makes complex stamping super easy. You can make copper clips, jaws, and HVAC components.

Deep Drawing stamping

Deep drawing is another popular method for shaping copper metals. Deep drawing uses copper sheets. Press machines apply enough force to convert into the shape specified by the die.

Want to know the exact process?

The first station manipulates the copper workpiece to make a blank from it. And a blank is a piece that has to undergo further processing to shape the copper workpiece.

Blank is placed on the die machine. With a punch machine, the copper workpiece is shaped into the required layout. It brings in the required length of the copper sheet also.

The task for the first station is done. The rest of the stations will do the sheet processing, adding features, and cutting the extra metal workpiece.

Common Copper Stamping Operations

Copper stamping is a collection of multiple procedures involving punching, bending, etc. All methods are synchronized to produce a perfect stamped piece of copper.

Let’s have a brief discussion of copper stamping operations.

● Punching

The punching process works like a punch by a stamping tool against the copper workpiece.

A single stroke by the tool shears off the pieces of the metal and creates a hole in the copper at different points. The accuracy of the punching determines the fineness of the metal stamping.

● Blanking

If you have got a copper workpiece and want to cut a specific portion from it, it is called a blanking process.

Whatever portions a stamping machine cuts from the workpiece are essential for further manufacturing. It is exactly opposite to the piercing in which cut-out parts are no longer required.

● Lancing

Lancing is a cutting process done by the stamping machine. Unlike the blanking, we do the partial cutting of the metal workpiece.

● Bending

Bending is a forming process involving the crucial steps of manufacturing the objects we need.

In the bending process, a metal workpiece is bent into multiple forms. For example, bowing the copper metals into the U or V shape bending. You can try whatever shape you expect from your copper workpiece.

To fulfill this process, you should have a PUNCH machine with the die to bend the copper sheet with the required force. When performing the process, you should consider using additional materials.

Why?

It irons out the complexity of the operation and makes the smooth operation possible.

● Coining

Coining requires more force compared to bending and needs more accuracy. The stamping part of the machine moves against the circular portion of the metal workpiece and turns it into the typical circular coin shape you need for further processing of the copper workpiece.

● Embossing

Once coining is done, it is time to think out of the box. You go for the final designs and processing of the copper metal.

For example, if you want to make decorative pieces with the flower imprinted on your copper workpiece, the embossing helps you out.

In this technique, the stamping machine raises the parts of the copper metal. Texts or shapes are printed on metal sheets.

That is how the whole process of copper stamping occurs.

Types of coppers used for stamping

Metal stamping on copper has yet another fanbase for real-world applications.

We have listed some of the most common cooper types of stamping. These are:

Copper

Copper is always an ideal choice for stamping. It has all the features mandated to turn a metal workpiece into the required shapes.

Brass

Brass has got good resistance and malleable features. There we use it for stamping in the metal industry.

Bronze

Bronze is a ductile metal with less brittle features. We deploy bronze in the metal stamping process.

Silver and Nickel

Good corrosion resistance, Malleable and ductile features make silver and nickel good for metal stamping.

Benefits of copper stamping

Copper stamping has several pros that catch the attention. Let’s take a look.

Minimal Material Wastage

Do you want to use all of your metal? Not a BIG deal in the copper stamping process. Every single part of your copper metal is precious. Stamping processes utilize it to make smaller to larger pieces. Therefore, material wastage is reduced to NO WASTE.

High efficiency

Stamping is a very efficient process. Multiple stamping machines operating simultaneously cut down the time and produce new objects faster.

High precision

Stamping provides accurate cutting and manufacturing of products through the sheet workpiece. Automated systems boost accuracy at set standards.

Applications of Copper Stamped Parts

You won’t believe it if I tell you that most real-life products owe to copper stamping—an electrical copper wire or some conducting parts of your Freezers in the home.

The electrical industry is not a single field where copper stamping finds its applications. Instead, the decoration industry uses it to manufacture different patterns and designs for ornaments in the home.

The architectural and aerospace industry utilizes the copper industry to manufacture some parts of an airplane.

And why is it so?

It is possible due to malleable and ductile features bending copper to tons of shapes. AC in our homes is an excellent example of copper stamping.

Conclusion

Copper is an IDEAL choice for metal stamping owing to the malleable and ductile conditions of the copper metal. You get efficient production with accurate stamping processes.
