Why Use Deep Drawn Copper Components?

Deep drawn copper components, when applied, provide efficient electrical conductivity, superior thermal management, and unparalleled design flexibility. Using copper for deep drawing components gives electrical systems exceptional conductivity.

Because copper is so malleable, it can easily transform into flexible, three-dimensional complex structures. This is how copper makes the transformations highly functional and meets specific requirements. Where heat dissipation is critical, copper is vital. It can efficiently conduct heat and dissipate it far and wide. It also makes components last longer by resisting corrosion. With our cutting-edge technology in deep drawing,, you can unlock new dimensions of performance and value in innumerable applications and industries.

Tools For Copper Deep Drawing Components

Drawing Press Machine

At JCL, we form copper deep drawing components with a press machine. Through this press machine, we create a tremendous force on the copper sheet and shape it. The deep drawing press machine determines the pressure and speed of the deep drawing process.


Die helps to give the desired shape to the copper deep drawing components. The die is made of steel and its cavity aligns with the copper components' shape. Dies ensure the accuracy and consistency of shape in all the copper deep drawing components.


A punch is a rod typically made with metal. We will use a punch to fit the copper sheet into the die and help it to form the shape of deep drawing components. Die and punch need to function cooperatively to manufacture accurate and complex deep-drawing components.

Blank Holder

During the deep drawing process, the blank holder holds the copper sheet tightly in one place so that it doesn’t move or wrinkle. To have a perfect shape it’s essential the copper sheet goes straight into the die.


Lubricants are also a very crucial element for the copper deep drawing process. They are like soap or oil and are used on the punch, die and copper sheet. These are used to minimize the friction between the deep drawing tools and the copper sheet. So it becomes smoother to draw the copper sheet into the die without any damage.

Types of Deep Drawing Techniques

  • Simple Deep Drawing: This drawing has straight sides and shallow depth. It is used for basic shapes.

  • Complex Deep Drawing: This design has multiple draws and intricate shapes which require advanced tooling.

  • Reverse Deep Drawing: To create this design, we draw the material inward and create a raised form.

  • Thin-Wall Drawing: This design demands the thinnest layer of copper. We push the limits of copper's ductility to create ultra-thin components.
