Copper Deep Drawn Pressed Components
What materials can be used for deep draw pressing?
Many metals are suitable for deep draw pressing. The most common are stainless steel, aluminium, brass, copper and cold rolled steel. The principal requirement is that the metal should be ductile so that the part can be created without putting any undue stress on it which could lead to cracks or weaknesses in the finished component.
What is the deep draw pressing process?
The process first involves creating a series of geometric dies. These are installed on the deep draw press. A blank metal component is then passed through the press, being pressed (or drawn) into each die in turn. At the end of the process, the final shape is achieved. Typical production speed is 60 parts a minute. The process can be repeated if a particularly complicated shape is required.
Some examples of common household items use deep draw pressed components – and benefit in terms of cost and aesthetics:
- Batteries
- Lipstick tubes / cosmetics containers
- Asthma inhalers
- Catheter holders
- Metal pen lids
- Metal ball point pen refills
- “Widgets” in beer cans
- Plumbing and heating fittings.
- Large enclosures
