Deep Drawn Pressings

Deep Drawn Pressings
Innovation. Experience. A worldwide leader in deep drawn pressings.

Stroud Metal has been on the cutting edge of deep drawn pressings technology for nearly a century, innovating highly developed methods to deliver cost-effective precision components to our customers across a wide range of industries and regions. We're constantly investing in new technology so that our engineers can bring you the very latest in state-of-the-art deep drawn presswork solutions.

Our expertise in deep draw pressings gives us the ability to manufacture an unparalleled range of parts that traditionally have been created by other processes, such as turning, casting or assembly. Deep draw can produce highly aesthetic complex designs that other manufacturing techniques can’t create without using expensive secondary operations. It’s also hugely versatile, capable of manufacturing items of any size, and in a variety of shapes.

What’s more, deep draw pressings offers tremendous value. With less material used in the process, there’s less waste, which reduces cost. Component quality is often higher than with other processes and shows better repeatability in production batches, meaning you get higher volume, higher quality – at a lower cost.

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

Those are just a few examples – any item, from any industry, that features a seamless metal tube could include a component that has been deep drawn pressed.

What materials can be used for deep draw pressings?

Many metals are suitable for deep draw pressings. 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 pressings 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.

When are deep draw pressings components used?

Where large volumes are involved, deep draw pressings is an extremely cost-effective process. This is because once the dies have been installed on the deep draw press, the process is entirely mechanical. We have engineered deep drawn components that have offered more than 85% reductions in unit cost when compared to the original machined parts. This makes the process ideal for high volume, low retail price items.
