Getting to Know More About Deep Drawn Pressing Process
Deep drawn presswork is one of the industrial manufacturing processes with various applications today. It involves the progressive formation of pieces from metal sheets into 3D-shape by mechanical drawing of the “blank” metal sheet by using a forming die that will cut into the metal thus forming the necessary shape for the finished product.
The deep drawing process works by feeding coiled lengths or strips of metal sheets into the metal press, which can be done manually or automatically. This will then be turned into a 3D-shape by drawing the “blank” sheet of metal into the forming die.
Generally, the process can be called deep drawing if the depth of the part drawn will exceed the diameter. A series of dies is necessary so that the specific depth of component will be attained and this is done by redrawing until the resulting product retains a metallic mold or cup shape. The process is otherwise known as reduction.
The process of deep drawn presswork is not entirely a simple process because in most cases the necessary size of component cannot be cut into the desired shape after the initial reduction process. Therefore, the component shall undergo a series of progressive reduction cycles until the necessary size is achieved.
The process becomes more complicated because it depends on what kind of material is utilized even though it can be used to most types of materials. However, even if this is so, there are still other metals that will not do well with deep drawn metallic presswork since the process involves high levels of stress that they are subjected to. The process may involve heat treatment operation, otherwise referred to as annealing, before it can be further processed by way of reductions.
Applications of Deep Drawn Pressing
Generally, the application of deep drawn pressing is wide including storage objects like tins and canisters. However, this process is not simply production of smaller items like these. The process of deep drawn pressing continues its way into the medical industry and automotive industry as well as other large industrial companies with metal components need manufactured via deep drawn pressing.

Advantages of Deep Drawn Pressing
There are several advantages when using deep drawn pressing. For instance, the mass-production of components and products has been made possible because the process can be performed repeatedly as soon as the dice and tooling required are prepared. The procedure can be done with less downtime and maintenance.
In addition, the process of deep drawn pressing is beneficial in generating products with high functionality. The end products are required to be lightweight but at the same time very strong or durable and this process are able to at
tain as such.
Furthermore, deep drawn p
ressing allows for more variety of shape especially those with geometries. As you know, cylindrical objects often gain benefit from this setup without sacrificing its
production quality and flow.
Simple Operation of Deep Drawn Pressing
The process of deep drawn pressing involves a metallic product or component and may require skill with professional hands especially those with metallic presswork.If you visit metal stamping manufacturers’ production unit, you can learn more about stainless steel pressings,steel pressing, aluminium pressing, deep drawn pressing process etc…
Understanding Deep Draw Pressing Process
Overview
Deep draw pressing is a fabrication process that makes seamless metal parts.
Reason behind the use of deep draw pressing
Deep-drawn-pressings
Manufacturing parts that were created traditionally through different processes like assembly, casting or turning has different advantages to both the designer and production expert including –
- Only a few material is required for deep draw pressing thus lessening material waste and the cost of the manufacturing process
- The process of deep drawing can manufacture components with complex designs, which is often not possible using other traditional fabrication techniques without the aid of expensive secondary processes
- The quality of finished components are better than other methods and demonstrates better results in producing repeated batches
Applications of Deep Draw Pressing Components
Deep draw pressed products often varies from small to large components and often with varying shapes such as square, cylindrical and rectangular. This method offers better flexibility.
Some of the deep draw pressing components can be found in the household. These items benefit from the cost and design of this process and it includes –
- Asthma inhalers
- Batteries
- Lipstick tubes/cosmetic containers
- Metal ballpoint pen refills
- Metal pen lids
- Plumbing and heating fittings
- Widgets in beer cans
In other words, all items that have metal tubing incorporated in them are usually items that have been deep drawn pressed, which are widely used in many industries.
Materials for Deep Draw Pressing
A lot of metals are used for this method including stainless steel, cold rolled steel, aluminium, copper and brass. The process requires that the metal used is ductile allowing the components to be manufactured without placing unnecessary stress on the metal that will lead to weaknesses or cracks to the finished products.
Process of Deep Draw Pressing
Deep draw pressing involves a series of geometric dies. A metal material is then passed through the press so it can either be pressed or drawn into each die. As a result, the final shape of item is achieved and it takes about an average of 60 components in a minute.
The process may be repeated if there is a need to manufacture complex shapes.
Stamping, otherwise known as progressive die pressing, is similar to deep draw pressing but is only able of producing shallow and simple components with the exception of using thin sheet metal instead of blanks. The progressive die pressing produces around 250 parts in a minute.
When to use deep draw pressing components
Deep draw pressing is a process which is a cost-effective method where production of large volumes is concerned. When the dies are installed on the machine, the process becomes completely mechanical. There is more than 85% reduction in the unit cost using engineered deep drawn components compared to the authentic parts. This process is therefore best when producing large volumes with low retail price.If you visit metal stamping manufacturers’ production unit, you can understand more about this topic.
